Résumé :

Objective: To examine eating disorder attitudes and psychopathology among female university students in Australia and Thailand. Method: Participants were 110 Caucasian Australians, 130 Asian Australians and 101 Thais in Thailand. The instruments included the Eating Attitudes Test (EAT) and the Eating Disorders Inventory (EDI). Results: Eating disorder attitudes and psychopathology scores in the Thai group were found to be highest. The Asian Australian group did not have significantly higher scores on the EAT-26 than the Caucasian Australian group, but had higher scores in some subscales of the EDI-2. That the Thai group had the highest scores in susceptibility to developing an eating disorder and eating disorder psychopathology may be partially explained in sociocultural terms, with pressure to be thin more extreme in Thailand than in Australia. The evidence suggested that unhealthy eating disorder psychopathology is not limited to Western societies but is already present in Thai and other Asian societies.

Résumé :

Objectives: Transtympanic pressure has been shown to influence endolymphatic hydrops. As endolymphatic hydrops plays a key role in Ménière’s disease, a few studies, undertaken by the inventors, manufacturers and associates of the Meniett device,have demonstrated positive short-term effects of transtympanic pressure treatment via the Meniett device in medically intractable Ménière’s disease. The aim of our study was to independently investigate the long-term efficacy and safety of transtympanic pressure treatment in the management of recalcitrant vertigo in Ménière’s disease.Design: Cross-sectional case study.Setting: Tertiary referral centre.Participants: Eighteen patients with Ménière’s disease, suffering from medically intractable symptoms. All patients in the study had Ménière’s disease according to the criteria of the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology, Head & Neck Surgery.Main outcome measurements: Outcome and severity of symptoms were assessed, using the six-point functional scale and the vertigo visual analogue scale (VAS), as recommended by the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology, Head & Neck Surgery. Changes of pure tone average thresholds and vestibular calorics before and during treatment with the Meniett device were recorded. The mean follow-up time was 18 months.Results: Twelve out of 18 patients showed significant improvement in the functional score and in the VAS. Five patients displayed an audiometric improvement, out of which three patients showed a pertaining significant hearing gain of more than 10 dB; the remainder had stable hearing levels. Of six patients without any improvement, four had previous invasive surgery for theirMénière’s disease and two had previous vestibular ablation with gentamicin.No changes in vestibular function were noted. There were no complications duringthe treatment with the Meniett device.Conclusion: According to this independent study, the Meniett device seems to be a minimally invasive, non-destructive treatment tool, which can reduce vertigo and associated functional handicap in Ménière’s disease. These effects are maintained up to 18 months after treatment so far. Previous surgical or chemical vestibular ablation procedures may adversely influence the effect of the Meniett device.

Texte intégral

Résumé :

The northern beef cattle herd accounts for more than half of Australia’s beef cattle population, and is a major source of anthropogenic methane emissions for Australia. National Greenhouse Gas Inventory predictions of methane output from Australian beef cattle are based on a predictive equation developed for British breeds of sheep and cattle offered temperate forage-based diets. However, tropical forage diets offered to cattle in northern Australia differ markedly from temperate forage-based diets used in the United Kingdom to develop the predictive equations. In this paper we review recent respiration chamber measurements of daily methane production for Brahman cattle offered a tropical forage or high grain diet, and compare them with values predicted using methodologies of the Australian National Greenhouse Gas Inventory Committee and the Intergovernmental Panel on Climate Change. We conclude that a reliable inventory of methane emissions for cattle in northern Australia can only be achieved after a wider range of tropical forage species has been investigated. Some opportunities for reducing methane emissions of beef cattle by dietary manipulation are discussed.

Texte intégral

Résumé :

Following the publication of Geoscience Australia Record 2014/09: Petroleum geology inventory of Australia’s offshore frontier basins by Totterdell et al (2014), the onshore petroleum section of Geoscience Australia embarked on a similar project for the onshore Australian basins. Volume I of this publication series contains inventories of the McArthur, South Nicholson, Georgina, Amadeus, Warburton, Wiso, Galilee, and Cooper basins. A comprehensive review of the geology, petroleum systems, exploration status, and data coverage for these eight Australian onshore basins was conducted, based on the results of Geoscience Australia’s precompetitive data programs, industry exploration results, and the geoscience literature. A petroleum prospectivity ranking was assigned to each basin, based on evidence for the existence of an active petroleum system. The availability of data and level of knowledge in each area was reflected in a confidence rating for that ranking. This extended abstract summarises the rankings assigned to each of these eight basins, and describes the type of information available for each of these basins in the publically available report by Carr et al (2016), available on the Geoscience Australia website. The record allocated a high prospectivity rating for the Amadeus and Cooper basins, a moderate rating for the Galilee, McArthur and Georgina basins, and a low rating for the South Nicholson, Warburton and Wiso basins. The record lists how best to access data for each basin, provides an assessment of issues and unanswered questions, and recommends future work directions to lessen the risk of these basins in terms of their petroleum prospectivity. Work is in progress to compile inventories on the next series of onshore basins.

Résumé :

This paper examines the empirical relationship between working capital management (WCM) and firm performance (FP) for Australasian publicly listed firms. Australia and New Zealand are attractive investment destinations due to their business friendly environments. The past two decades have seen increased academic attention in studies linking WCM and FP across various parts of globe. The empirical relationship between WCM-FP has not been sufficiently examined in regards to Australian and New Zealand firms. This study measures the role of WCM during the 2008 global financial crisis in both Australia and New Zealand firms. This study uses System General Method of Moments to address the endogeneity problem in order to reduce the possibility of biased results. The results show that WCM has a significant relationship with FP. More specifically, the Cash Conversion Cycle (CCC) and the Inventory Conversion Period (ICP) exhibit negative relationships with FP indicating that a reduction in the CCC and the ICP help to improve FP in Australasian firms. However, in the case of the Average Collection Period (ACP) and the Average Payment Period (APP), the results vary between both countries. In Australia, the ACP has no significant relationship, whereas APP has a positive relationship. This is contrary in the case of New Zealand firms. Another important finding is that firms in both markets were relatively efficient collecting their receivables during the 2008 global financial crisis period. These findings provide new empirical evidence that WCM matters for improving FP in Australasian firms.

Résumé :

Grain production is a key source of food globally and is an important agricultural system for the Australian economy. Environmental impacts such as the emissions of greenhouse gases (GHG) associated with grain production are well documented and the Australian grains industry has strived to ensure ongoing improvement. To facilitate this improvement, the industry funded the development of life cycle inventories to provide broad geographical coverage. Cradle-to-gate inventories for wheat were developed for each of the grains industry agro-ecological zones, and inventories were developed for minor cereal crops (e.g. barley, sorghum), oilseeds (i.e. canola) and legumes where relevant. Data for inventory development were taken from numerous sources and validated by using data collected through interviews with experts in each agro-ecological zone. Inventory data were also collected so that indicators in addition to global-warming impacts could be assessed. Global warming impacts for wheat production ranged from 193 to 567 kg carbon dioxide equivalents (CO2-e) t–1, and global warming impacts were 597–851, 333–361, 169–285 and 74–672 kg CO2-e t–1 for canola, sorghum, barley and grain-legume production, respectively. Results for eutrophication, freshwater ecotoxicity, land-use and abiotic depletion (fossil-fuel use) are also presented.

Résumé :

Purpose – This paper aims to document the measures taken by Australian corporate treasurers in the areas of cash, inventory, accounts receivable, accounts payable and risk management to survive the global financial crisis (GFC). Design/methodology/approach – Using qualitative techniques like interviews and a survey questionnaire, this paper summarises the various measures adopted by working capital managers. Findings – The results show that more than half of the participants in the survey altered their working capital management practices during the crisis. Capital expenditure was curtailed, as they aimed at preserving their cash levels while reducing inventory levels. Credit worthiness of institutions became more important, and there was a general decline in credit availability. The results also show that Australian working capital managers exhibit behavioural biases, particularly overconfidence. Originality/value – It is the first paper that uses open-ended questions to capture the effects of the GFC on working capital management in Australia.

Résumé :

Coal seam gas (CSG) accounts for about one-quarter of natural gas production in Australia and rapidly increasing amounts globally. This is the first study worldwide using airborne measurement techniques to quantify methane (CH 4 ) emissions from a producing CSG field: the Surat Basin, Queensland, Australia. Spatially resolved CH 4 emissions were quantified from all major sources based on top-down (TD) and bottom-up (BU) approaches, the latter using Australia's UNFCCC reporting workflow. Based on our TD-validated BU inventory, CSG sources emit about 0.4% of the produced gas, comparable to onshore dry gas fields in the USA and The Netherlands, but substantially smaller than in other onshore regions, especially those where oil is co-produced (wet gas). The CSG CH 4 emission per unit of gas production determined in this study is two to three times higher than existing inventories for the region. Our results indicate that the BU emission factors for feedlots and grazing cattle need review, possibly requiring an increase for Queensland's conditions. In some subregions, the BU estimate for gathering and boosting stations is potentially too high. The results from our iterative BU inventory process, which feeds into TD data, illustrate how global characterization of CH 4 emissions could be improved by incorporating empirical TD verification surveys into national reporting. This article is part of a discussion meeting issue ‘Rising methane: is warming feeding warming? (part 1)’.

Texte intégral

Résumé :

This study investigated whether the conditions in which the Coopersmith Self-Esteem Inventory was administered had any effect on subjects' scores on the Inventory. The study also examined normative and reliability scores in the ACT, the effect of various demographic variables and the relationship between happiness scores and self-esteem. The Coopersmith Self-Esteem Inventory was administered to groups of year seven students from a Canberra high school under two different conditions: friendly and impartial. After five weeks the Inventory was readministered to rearranged groups under the different conditions. No significant differences were found in the scores from the students in the different conditions. No significant differences were found on an indication of student happiness under each condition. A normative value was calculated combining scores from the first testing sessions and a test-retest reliability correlation calculated from combined scores from the first and second testing sessions. The validity of the lie scale and the use of the Inventory in Australia are discussed. With a few reservations it appears that the Coopersmith Self-Esteem Inventory measures a relatively stable trait and is a reliable measure of overall self-esteem. A summary of recent literature using the Coopersmith Self-Esteem Inventory is included. Mean self-esteem scores on the Coopersmith Self-Esteem Inventory were compared with students grouped by sex, socio-economic status, birth order, whether they came from a single parent family or whether their mother worked. Significant differences were found with SES and birth order but recent literature shows that these variables are often interrelated and results may be instrument dependent. New self-concept tests (based on a sound theoretical framework) are being developed which acknowledge the multidimensionality of self-concept and appear more able to detect variation in facets of self-concept.

Texte intégral

Résumé :

This thesis focuses on the factors which lead to off-shore manufacture of Australian inventions. It establishes this phenomenon as a problem, both in terms of its incidence in the post-war period, and in the strategic importance of innovative activity to economic growth. The thesis utilises a case study approach and concentrates on the experiences of one company, the Orbital Engine Corporation (Orbital). In 1989 Ralph Sarich, inventor of the Orbital Combustion Process (OCP) engine and founder of Orbital, signed an agreement with the Michigan state government to manufacture the engine in the United States of America (USA), in preference to several alternative sites in Australia and overseas. This occurred in the context of Orbital actively pursuing assistance from the Australian government to secure local production. The research question is: Why did Orbital decide to manufacture its engine invention ofshore? A multi-disciplinary approach to this question is adopted. Three different conceptual frameworks are employed: industrial organisation theory, market failure theory and policy network theory. The analysis is not structured around a pre-existing hypothesis; instead, the aim is to generate potential explanations for more rigorous testing by subsequent researchers. The thesis concludes that, in terms of industrial organisation theory, the decision to manufacture OCP engines off-shore was a function of the poor quality of the Australian industrial context and the failure by those seeking assistance from the Commonwealth government to stress Orbital's status as an exemplary enterprise in Australian industry. Market failure theory indicated that offshore production of the OCP engine was made more likely by the suboptimal operation of the price mechanism, the neglect of market failure arguments by those supporting local production of the engine and 'government failure'. Policy network theory explained Orbital's decision as the result of: ineffective employment of negotiation tactics by proponents of the engine's domestic manufacture; and the chaotic nature of negotiations which allowed certain personal and ideological prejudices to dominate the issue resolution process. It is shown that some or all of these explanations underlie a number of other examples where Australian inventions have been manufactured offshore. In commenting on policy implications, the thesis points to the economic potential of the Orbital invention and the value of interventionist industry policy. The thesis identifies a number of actions which might be taken to lower the incidence of foreign manufacture of Australian inventions. Further research is necessary to determine the relative importance of the various factors which are identified as leading to offshore production. In addition, there remains a particularly crucial need to improve the social efficiency of existing cost-benefit techniques employed by government policy-makers and commercial analysts.

Texte intégral

Résumé :

This research study was in the field of adult education, focusing on the role of adult educators. Sixty four adult educators in the Australian Capital Territory, from a wide range of institutions took part in the study. The educational orientation of the adult educators, on an andragogical-pedagogical continuum, was measured by The Educational Orientation Questionnaire, (Hadley, 1974). This test was based on Knowles, theory of andragogy "the art and science of helping adults learn" and its corollary, pedagogy, "the art of teaching children" (Knowles, 1985). The E.O.Q. tested adult educators' attitudes in six areas of education to discover the extent to which educators were more andragogical or pedagogical in their orientation. Four personality dimensions of adult educators were measured by The Personal Style Inventory (Champagne and Hogan, 1979) - a test based on Jung's theory of psychological types. The data was analysed and four null hypotheses were tested. Two were rejected and two were accepted. The findings revealed that there was a statistically significant correlation at the .01 level of significance, showing a definite relationship between two of the dimensions, extraversion-introversion and sensing-intuition, and the educational orientation of adult educators: extraversion and intuition with a more andragogical orientation and introversion and sensing with a more pedagogical orientation. The interpretation of these findings raised numerous questions and issues on the role of adult educators as well as recommendations for further research on the correlation of other variables with the educational orientation of adult educators.

Résumé :

The government has indicated that innovation fosters economic growth and is essential to maintaining a competitive position in international markets. Patents are the preferred mechanism by which the Australian Government and other governments encourage their nationals to protect their innovations. The question of the entitlement was raised in several cases in the Federal Court of Australia where there has been a failure to name all of the inventors on a patent grant (non-joinder) or where persons were mis-named as inventors, who were not and consequently have no interest in a grant (rnis-joinder). In both cases, parties who were not themselves daiming an entitlement to the invention, brought objections based on a number of grounds, including entitlement. The results have been the revocation of the patent in the case on the non-joinder of an inventor and in the case of mis-joinder, the preliminary view of a judge of the Federal Court has been, that the patent would be invalid through lack of entitlement. The result is that competitors are permitted to 'exploit' the invention, as the subject matter is not protected by a patent. The implications are far reaching, For example, where a research team in collaboration with another develops an invention but omits the inventive contribution of even one member of one team or includes a person who has not made an inventive contribution in the patent grant, the patent will be invalid. In these circumstances, the author considers that the result produces a disincentive to innovate. Consideration of this area in other jurisdictions reveals that the U.S. and the U.K. have recognised this as an unsatisfactory state of affairs. As a result, Congress in the U.S. made provision in their Patent Code in the early 1950's, that in the case of error or mistake giving rise to a non-joinder or mis-joinder of inventors, the patent would not be invalid but could be rectified by the Director of Patents and Trade Marks (the 'Director'). In the U.K., the Comptroller has powers to deal with a wide variety of cases involving entitlement to ownership of a patent. The situations include but are not limited to cases where some but not all of the persons entitled to the grant have been granted the patent, i.e. non-joinder, or where a person entitled to be granted a patent, has been granted a patent together with a person who is not entitled, i.e. mis-joinder. The thesis will focus on the non-joinder and mis-joinder of inventors, but the U.K. provision addresses a wider field of parties entitled, whether entitled as inventors or on some other basis. In addition, the U.K. and Germany have made provision restricting the persons who are able to challenge a patent on entitlement grounds. This is restricted to those persons having an interest in the patent, rather than open to any person, as is the case in Australia. The Australian decisions have been determined on historic cases dating back to the 17th century. It is timely to consider amendments which will overcome revocation of patents under Australian law, for what is essentially a matter between the persons interested. These amendments will accordingly encourage innovation, particularly in an environment where intellectual property has taken on greater importance and where the identification of the inventor has become more complex as collaborations in research become more common.

Résumé :

Although there are numerous instruments available for assessing classroom learning environments at the tertiary level, no instrument has been specifically designed and validated for measuring the business management education learning environment (Brennan & Ahmad, 2005). My aims were (1) to design, develop and validate an instrument, the Business Management Education Learning Environment Inventory (BMELEI), for assessing business management students’ perceptions of the psychosocial learning environments of university seminars and tutorials and (2) to relate learning environment to attitudes towards the subject and attitudes towards the case study teaching strategy. This study is distinctive in that it involved both quantitative and qualitative methods. The BMELEI and two attitude scales were administered to 480 final-year undergraduate and postgraduate business studies students in 30 classes at both Curtin University of Technology and Edith Cowan University in Perth, Australia. The qualitative component of the study involved semi-structured interviews with 42 randomly-selected participants from the above universities. Factor analysis supported a six-factor structure (Student Cohesiveness, Teacher Support, Involvement, Task Orientation, Cooperation and Equity) with scale alpha reliabilities ranging from 0.78 to 0.90 for the actual form and from 0.80 to 0.92 for the preferred form using the individual as unit of analysis. Students’ attitudes were found to be positively associated with classroom learning environment.
Also differences were found between students’ perceptions of the actual and preferred classroom environment, and between male and female students’ perceptions of the actual and preferred classroom environment. Findings suggested that students preferred a more positive and favourable classroom learning environment than they perceived as being actually present.

Résumé :

This study explores the issues involved in the theoretical bases, rationale and implementation of practical work in junior secondary science programs. The part that practical work has played in science education, both internationally and in Australia, is reviewed. Links are made between statements made by science educators more than 200 years ago to those made by modern day researchers into science teaching and learning. The study draws together the research traditions of the philosophy of science, science curriculum development, learning environments, and educational psychology. The researcher has carried out a multi-stage field study using both qualitative and quantitative methods to achieve the objectives of the study. Developments in the philosophy of science as they impinge on science education are reviewed. Science practicals are defined for the purposes of this study and a new Theoretical Model for Science Practicals is proposed. The model enables the description and statement of purpose of eight types of science practicals. The target population of the study is Australian science teachers and students. The model provides a theoretical basis for the development of the survey instrument, Science Practicals Inventory (SPI), to investigate students’ perceptions of the use of practicals in science learning. The eight types of practicals described in the model were used as the scales for the SPI. Qualitative data collected during separate group interviews of science teachers and students supported the development of the SPI together with quantitative data from three pilot studies. The SPI was validated using samples of high school students from Tasmania and Western Australia.
Using statistical procedures involving factor analyses, alpha reliability, discriminant validity, and ANOVA, a valid, reliable, efficient, eight scale, 50 item instrument has been developed. Analysis of the quantitative and qualitative data in this study enabled issues involved in the theoretical bases, rationale and implementation of practical work in junior secondary science programs to be clarified and better understood. The results of this study include implications for science curricula and recommendations for further research and are generalizable to science teachers and students in Australia. The SPI is available for further application in action research, science program evaluation, science teacher professional learning and science program renewal.

Résumé :

Spatial and temporal information on catchment sediment sources and sinks can provide an improved understanding of catchment response to human-induced disturbances. This is essential for the implementation of well-targeted catchment-management decisions. This thesis investigates the nature and timing of catchment response to human activities by examining changes in sediment sources and sinks in a dry-tropical subcatchment of the Great Barrier Reef (GBR) catchment area, in northeastern Australia. Changes in catchment sediment sources, both in terms of spatial provenance and erosion type, are determined using sediment tracing techniques. Results indicate that changes in sediment source contributions over the last 250 years can be linked directly to changes in catchment land use. Sheetwash and rill erosion from cultivated land (40-60%) and channel erosion from grazed areas (30-80%) currently contribute most sediment to the river system. Channel erosion, on a basin-wide scale, appears to be more important than previously considered in this region of Australia. Optically stimulated luminescence and 137Cs dating are used to determine pre-and post- European settlement (ca. 1850) alluvial sedimentation rates. The limitations of using 137Cs as a floodplain sediment dating tool in a low fallout environment, dominated by sediment derived from channel and cultivation sources, are identified. Low magnitude increases in post-disturbance floodplain sedimentation rates (3 to 4 times) are attributed to the naturally high sediment loads in the dry-tropics. These low increases suggest that previous predictions which reflect order of magnitude increases in post-disturbance sediment yields are likely to be overestimates. In-channel bench deposits, formed since European settlement, are common features that appear to be important stores of recently eroded material. The spatially distributed erosion/sediment yield model SedNet is applied, both with generic input parameters and locally-derived data. Outputs are evaluated against available empirically-derived data. The results suggest that previous model estimates using generic input parameters overestimate post-disturbance and underestimate predisturbance sediment yields, exaggerating the impact of European catchment disturbance. This is likely to have important implications for both local-scale and catchment-wide management scenarios in the GBR region. Suggestions for future study and the collection of important empirical data to enable more accurate model performance are made.

Résumé :

This chapter discusses the extra-territorial influence of American English on Australian English, in comparison with other varieties within the spectrum of World Englishes. Its aim is to compare the different orientations to American English in Australia that can be observed using qualitative and quantitative methods, and so to illuminate the different ways in which extra- and intra-territorial influences can impact on individual varieties. Two kinds of evidence are presented: (i) attitudinal data derived from Australians commenting in the complaint tradition on elements of pronunciation and spelling; and (ii) corpus data on lexical and morphosyntactic sets where shifting preferences are attributed to American influence. While perceptions of the extent of American influence are inflated, the inventory of Americanisms used in Australia continues to grow.

Résumé :

Australia has a coastline of around 32,000 km, with varying rock types and structure, coastal type and climate. Outstanding and representative coastal sites form a significant part of the Australian inventory. Major terrains included inland deserts (for example the Simpson Desert dune field, northern tropical savannah (the Kakadu World Heritage Region, glacial and periglacial upland in the far south (southwest Tasmania, broad inland riverine plays and the young volcanic provinces of southeastern Australia and northeastern Australia.

Résumé :

The Environmental Impact Statement (EIS) for the proposed Australian National Repository for low and short-lived intermediate level radioactive waste was submitted to Environment Australia for approval in the summer of 2002 and has subsequently undergone a consultancy phase with comments sought from all relevant stakeholders. The consultancy period is now closed and responses to the comments have been prepared. This paper describes some of the issues relevant to determining the radiological risk associated with the repository to meet the requirements of the EIS. These include a brief description of the three proposed sites, a description of the proposed trench design, an analysis of the radioactive waste inventory, the proposed approach to developing waste acceptance criteria (WAC) and the approach taken to determine radiological risks during the post-institutional control phase. The three potential sites for the repository are located near the Australian Department of Defence site at Woomera, South Australia. One site is inside the Defense site and two are located nearby, but outside of the site perimeter. All have very similar, but not identical, topographical, geological and hydrogeological characteristics. A very simple trench design has been proposed 15 m deep and with 5 m of cover. One possible variant may be the construction of deeper borehole type vaults to dispose of the more active radioactive sources. A breakdown of the current and predicted future inventory will be presented. The current wastes are dominated in terms of volume by some contaminated soils, resulting from experiments to extract U and Th, and by the operational wastes from the HIFAR research reactor at ANSTO. A significant proportion of the radionuclide inventory is associated with small volumes of sources held by industry, medical, research and defence organisations. The proposed WAC will be described. These are based on the current Australian guidelines and best international practice. The preliminary radiological risk assessment considered the post-institutional control phase in detail with some 12 scenarios being assessed. These include the impact of potential climate change in the region. The results from the risk assessment will be presented and discussed. The assessment work is continuing and will support the license application for construction and operation of the site. Please note that this is not the final assessment for the licence application.

Résumé :

13 uranium mines operated in the South Alligator Valley of Australia’s Northern Territory between 1953 and 1963. At the end of operations the mines, and associated infrastructure, were simply abandoned. As this activity preceded environmental legislation by about 15 years there was neither any obligation, nor attempt, at remediation. In the 1980s it was decided that the whole area should become an extension of the adjacent World Heritage, Kakadu National Park. As a result the Commonwealth Government made an inventory of the abandoned mines and associated facilities in 1986. This established the size and scope of the liability and formed the framework for a possible future remediation project. The initial program for the reduction of physical and radiological hazards at each of the identified sites was formulated in 1989 and the works took place from 1990 to 1992. But even at this time, as throughout much of the valley’s history, little attention was being paid to the long term aspirations of traditional land owners. The traditional Aboriginal owners, the Gunlom Land Trust, were granted freehold Native Title to the area in 1996. They immediately leased the land back to the Commonwealth Government so it would remain a part of Kakadu National Park, but under joint management. One condition of the lease required that all evidence of former mining activity be remediated by 2015. The consultation, and subsequent planning processes, for a final remediation program began in 1997. A plan was agreed in 2003 and, after funding was granted in 2005, works implementation commenced in 2007. An earlier paper described the planning and consultation stages, experience involving the cleaning up of remant uranium mill tailings and other mining residues; and the successful implementation of the initial remediation works. This paper deals with the final planning and design processes to complete the remediation programme, which is due to occur in 2009. The issues of final containment design and long term stewardship are addressed in the paper as well as some comments on lessons learned through the life of the project.

Résumé :

Gas production flowlines are presenting flow assurance challenges in hydrate management resulting from low ambient seawater temperatures in an increasing number of deepwater developments. During operation the equilibrium hydrate temperature of the produced fluid may be above the minimum seabed temperature, and hence there is a risk of hydrate blockage in the subsea system should the hydrate inhibition system fail. The continuous injection of MEG, with little or no insulation of the subsea system, is a common hydrate mitigation strategy for a gas production system. If insufficient inhibitor is injected there is a risk of hydrates forming and potential blockage of the pipeline in parts of the field. The industry-preferred approach for hydrate blockage remediation is Dual Sided Depressurisation (DSD). The objective is to depressurise the flowline to below hydrate onset conditions, allowing hydrate dissociation and safely disposing of the gas inventory. This is typically performed by one of two methods; installation of a dual flowline system for facility based depressurisation (with CAPEX implications); or a Mobile Offshore Drilling Unit (MODU) can be connected to an appropriate point upstream of the blockage to allow simultaneous depressurisation at the MODU and the facility (with OPEX implications). It is recognised that either method incurs significant costs. Typically the cost and time uncertainties of bringing in a MODU to solve these production stoppages is unattractive. Consequently subsea gas developments have often incurred the increased CAPEX of providing dual flowlines to permit DSD from the facility. An optimisation of the MODU-based intervention method is the subject of this paper. The feasibility of using a “lightweight” intervention vessel (for example an Offshore Support Vessel) in place of the MODU to depressurise the flowline is discussed. This paper discusses hydrate remediation difficulties and case studies; presents emerging hydrate remediation methods and briefly introduces vessel requirements. In discussing this optimisation, this paper also presents an introduction to hydrate remediation theory, some practical challenges, case studies and vessel requirements. The study concluded: • Significant CAPEX reductions may be achieved by adopting the outlined strategy; namely avoiding dual flowline infrastructure, and ensuring a reduced response time and day rate for any hydrate remediation operations to be performed. • For this strategy to be adopted cost effectively, pre-engineering, along with suitable contractual arrangements, are required to make the necessary equipment and personnel resources readily available should a hydrate blockage occur. For assets in remote locations, e.g. Australia, making the resources available is a significant challenge. • Flowline system access for depressurisation may be achieved by two methods; via the subsea Christmas tree or via suitably located fluid injection/vent access point(s).
