Résumé :

Surveys of microbial communities across transitions coupled with contextual measures of the environment provide a useful approach to dissect the factors determining distributions of microorganisms across ecological niches. Here, monthly time-series samples of surface seawater along a transect spanning the nearshore coastal environment within Kāneʻohe Bay on the island of Oʻahu, Hawaiʻi, and the adjacent offshore environment were collected to investigate the diversity and abundance of SAR11 marine bacteria (order Pelagibacterales) over a 2-year time period. Using 16S ribosomal RNA gene amplicon sequencing, the spatiotemporal distributions of major SAR11 subclades and exact amplicon sequence variants (ASVs) were evaluated. Seven of eight SAR11 subclades detected in this study showed distinct subclade distributions across the coastal to offshore environments. The SAR11 community was dominated by seven (of 106 total) SAR11 ASVs that made up an average of 77% of total SAR11. These seven ASVs spanned five different SAR11 subclades (Ia, Ib, IIa, IV, and Va), and were recovered from all samples collected from either the coastal environment, the offshore, or both. SAR11 ASVs were more often restricted spatially to coastal or offshore environments (64 of 106 ASVs) than they were shared among coastal, transition, and offshore environments (39 of 106 ASVs). Overall, offshore SAR11 communities contained a higher diversity of SAR11 ASVs than their nearshore counterparts, with the highest diversity within the little-studied subclade IIa. This study reveals ecological differentiation of SAR11 marine bacteria across a short physiochemical gradient, further increasing our understanding of how SAR11 genetic diversity partitions into distinct ecological units.

Résumé :

Purpose – The purpose of this paper is to find good values of onsite-offshore team strength; number of hours of communication between business users and onsite team and between onsite and offshore team so as to reduce project cost and improve schedule in a global software development (GSD) environment for software development project. Design/methodology/approach – This study employs system dynamics simulation approach to study software project characteristics in both co-located and distributed development environments. The authors consulted 14 experts from Indian software outsourcing industry during our model construction and validation. Findings – The study results show that there is a drop in overall team productivity in outsourcing environment by considering the offshore options. But the project cost can be reduced by employing the offshore team for coding and testing work only with minimal training for imparting business knowledge. The research results show that there is a potential to save project cost by being flexible in project schedule. Research limitations/implications – The implication of the study is that the project management team should be careful not to keep high percentage of manpower at offshore location in distributed software environment. A large offshore team can increase project cost and schedule due to higher training overhead, lower productivity and higher error proneness. In GSD, the management effort should be to keep requirement analysis and design work at onsite location and involves the offshore team in coding and testing work. Practical implications – The software project manager can use the model results to divide the software team between onsite and offshore location during various phases of software development in distributed environment. Originality/value – The study is novel as there is little attempt at finding the team distribution between onsite and offshore location in GSD environment.

Résumé :

The global lifestyle of this modern world has become more dependent on petroleum-based products, whose applications are involved almost everywhere. Since a large quantity of oil is being used on a daily basis, the spilling of oil by various means during its storage and transportation has become inevitable. This work focuses on the spilling of oil in a marine environment, generally referred to as an offshore oil spill, in contrast to an onshore oil spill associated with a terrestrial environment. These oil spills not only devastate the natural resources and unsettle the economy, they also jeopardize marine life, as well as human health. The remediation of an oil spill remains very challenging, when the disaster is associated with a large aerial extent. In this context, a sound understanding is required on the origin, seeping, composition and properties of the spilled oil in order to better monitor the spreading of the oil spill. In this manuscript, a detailed list of fundamental queries, which will be required to be addressed at the instance of an oil spill has been deduced, which will be extremely useful for the oil spill respondents as there are no previous studies that exclusively provide the type and nature of data required to be collected, immediately following an oil spill. Furthermore, this manuscript has deduced a list of sensitive and essential plots that will be required in order to analyse and forecast the spreading of an oil spill. An essence of weathering and its associated movement of oil spill has been included.

Résumé :

Changing the conditions of offshore environment influences the offshore units' stability. In paper, a study of the impact of marine environment on a jackup rig was implemented. Firstly, the procedures of departure, transit, and emplacement on any emergency jacking location / stand by location are reviewed. After that, the conditions of weather forecasting are predicted and computed such as wave and wind lengths, speeds, and heights. Maps of changing wind and wave conditions are plotted. Surveying methods are used to determine the final location of the jackup rig. Maps of positioning the jackup rig are constructed. Additionally, the impact forces on the rig derrick are therefore computed. The developed results are effectively predicting the safe conditions and optimizing the positioning survey of the rig.

Résumé :

A three dimensional computational model of a full scale axial flow tidal turbine has been used to investigate the effects of a range of realistic environmental conditions on turbine performance. The model, which is based on the Reynolds averaged Navier-Stokes equations, has been developed using the commercial flow solver ANSYS Fluent. A 1:30 scale tidal turbine is simulated in an open channel for comparison to existing experimental data. The rotor blades are directly resolved using a body-fitted, unstructured computational grid. Rotor motion is enabled through a sliding mesh interface between the rotor and the channel boundaries. Reasonably good agreement in thrust and power is observed. The computed performance curves are offset from the measured performance curves by a small increment in rotor speed. Subsequently, a full scale axial flow turbine is modelled in a variety of conditions representative of tidal channel flows. A parametric study is carried out to investigate the effects of flow shear, confinement and alignment on turbine performance, structural loading, and wake recovery. Mean power and thrust are found to be higher in sheared flow, relative to uniform flow of equivalent volumetric flow rate. Large fluctuations in blade thrust and torque occur in sheared flow as the blade passes through the high velocity freestream flow in the upper portion of the profile and the lower velocity flow near the channel bed. A stronger shear layer is formed around the upper portion of the wake in sheared flow, leading to enhanced wake mixing. Mean power and thrust are reduced when the turbine is simulated at a lower position in a sheared velocity profile. However, fluctuations in blade loading are increased due to the higher velocity gradient. The opposite effects are observed when the turbine operates at greater heights in sheared flow. Flow misalignment has a negative impact on mean rotor thrust and power, as well as on unsteady blade loading. Although the range of unsteady loading is not increased significantly, additional perturbations are introduced due to interactions between the blade and the nacelle. A deforming surface is introduced using the volume-of-fluid method. Linear wave theory is combined with the existing free surface model to develop an unsteady inflow boundary condition prescribing combined sheared flow and free surface waves. The relative effects of the sheared profile and wave-induced velocities on turbine loading are identified through frequency analysis. Rotor and blade load fluctuations are found to increase with wave height and wave length. In a separate study, the performance of bi-directional ducted tidal turbines is investigated through a parametric study of a range of duct profiles. A two dimensional axi-symmetric computational model is developed to compare the ducted geometries with an unducted device under consistent blockage conditions. The best-performing ducted device achieves a peak power coefficient of approximately 45% of that of the unducted device. Comparisons of streamtube area, velocity and pressure for the flow through the ducted device shows that the duct limits the pressure drop across the rotor and the mass flow through the rotor, resulting in lower device power.

Résumé :

Includes bibliographical references.
The extraction of mineral resources from deep ocean waters has been made possible by the development of large compliant offshore structures. Mooring cables are crucial components in these offshore facilities and form the basis of this study. The aims of this thesis are: to provide a comprehensive review on all aspects of cables, to determine criteria for numerical modelling, and to ascertain the capabilities of the finite element method for cable analyses using the F.E. package ABAQUS. Difficulties associated with large sag cables arise as a result of their inherent flexibility which causes ill-conditioning of the stiffness matrices. Furthermore, the cable winding configuration causes a nonlinear stress-strain relationship, it's sagged geometry results in nonlinear strain-displacement relations, and the immersion in water leads to nonlinear fluid loadings arising from Morison's Equation as well as uncertainties in the fluid parameters. Various models, starting with the developed. Convergence difficulties basic catenary, have been at start-up, caused by a lack of stiffness in the transverse direction, are avoided by supporting the cable when applying loads. It is further established that numerical analyses of flexible structures are most stable in dynamic analyses and when under tension. In general both displacement based isoparametric and hybrid beam elements were found to be more reliable and applicable than truss elements. Cable whip, ocean floor contact and harmonic motions of cables were analysed. Finally a cable/tower interaction was modelled and subjected to a Stokes's wave. Conclusions and guidelines are presented based on the numerical experiments carried out in this study.

Résumé :

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO
Os sistemas de produção de petróleo em águas profundas, incluindo as unidades flutuantes de produção (plataformas ou navios) e todos os equipamentos que participam da produção são atualmente projetados por complexos sistemas de modelagem computacional. Tais sistemas envolvem as áreas de cálculo estrutural, meteo-oceanografia (forças de correntes, ondas e ventos), hidrodinâmica, risers (tubos de aço rígidos ou flexíveis para levar o óleo do poço em sub-superfície até a unidade de produção), sistemas de ancoragem, equipamentos submarinos, fundações e avaliação de risco geológico-geotécnico. O projeto de uma nova unidade de produção é um processo longo e custoso, podendo durar anos e consumir centenas de milhões de dólares, dependendo da complexidade da unidade e da maturidade da tecnologia desenvolvida para tornar o projeto econômica e tecnicamente viável. Os projetos são conduzidos por diversos especialistas, por vezes geograficamente dispersos, gerando artefatos e resultados independentes, porém altamente inter-relacionados. A necessidade de colaboração é uma característica inerente aos projetos de unidades flutuantes de produção para águas profundas. A possibilidade de compartilhar informações entre usuários, controlar a execução de diferentes ferramentas de modelagem, visualizar e manipular modelos 3D virtuais em ambientes imersivos de Realidade Virtual vem empurrando os limites das atividades dos times na indústria do petróleo especialmente em Engenharia de Petróleo. O objetivo desta tese é o de fundamentar os princípios e equacionar os principais problemas para o desenvolvimento de um Ambiente Colaborativo para Engenharia, denominado CEE (Collaborative Engineering Environment), de forma a permitir a visualização colaborativa e interpretação dos resultados de simulações criadas nos projetos de engenharia, que em geral envolvem também diferentes especialidades. Devido à característica multidisciplinar dos projetos, a visualização colaborativa torna-se um componente de fundamental importância durante o ciclo de vida de projetos de engenharia, especialmente os da área de Engenharia Offshore, utilizada neste trabalho como caso de estudo. Propomos um ambiente integrado para visualização colaborativa a ser usado pelas equipes de engenheiros projetistas durante a execução e controle de projetos de engenharia complexos como é o caso dos projetos de unidades flutuantes de produção para águas profundas. Os requisitos do sistema foram levantados com o objetivo de permitir uma colaboração efetiva entre os participantes, criando um ambiente propício para discussão, validação, interpretação e documentação dos resultados das simulações executadas durante as fases de um projeto de engenharia. Para aumentar ainda mais a capacidade de interpretação e uma melhor compreensão dos resultados o suporte a visualização em ambientes imersivos 3D também esta disponibilizado na ferramenta de visualização utilizada, que foi especialmente adaptada para a área de Engenharia Offhore. Para atingir estes objetivos, propomos uma Arquitetura Orientada a Serviços para o CEE. Esta arquitetura é composta pela integração de diferentes tecnologias de Trabalho Colaborativo Auxiliado por Computador (CSCW), Realidade Virtual e Computação em Grade. Utiliza-se um sistema de Gerência de Workflows de Experimentos Científicos (ScWfMS), baseado em BPEL (Business Process Execution Language), para execução de simulações de engenharia em uma infra-estrutura de computação em grade subjacente e um sistema de Videoconferência (VCS) para suporte a colaboração de áudio e vídeo. Para a visualização dos resultados um sistema de visualização, especializado para Engenharia Offshore, ENVIRON, foi desenvolvido em conjunto com a equipe da PUC-Rio/TecGraf.
Deep-water production systems, including floating production units (platforms or ships) and all the equipments playing a part in the production process, are currently designed by means of complex computational modeling systems. Those systems involve the areas of structural calculus, meteo-oceanography (currents, waves and wind forces), hydrodynamics, risers (rigid or flexible steel pipes for carrying oil from the well in subsurface up to the production unit), mooring systems, submarine equipment, seabed foundations and Geologic/Geotechnical risk assessment. The project of a new production unit is a lengthy and expensive process, that can last many years and consume hundreds of million of dollars, depending on the complexity of the unit and how mature is the technology developed to make the project technically and economically feasible. Projects are conducted by diverse specialists, sometimes geographically distributed, yielding independent but highly interrelated artifacts and results. The need for collaboration is an inherent characteristic of deep-water floating production unit projects. The possibility to share information among users, control the execution of different modeling tools, visualize and manipulate virtual 3D models in immersive Virtual Reality (VR) environments is pushing the limits of teamwork activities in oil and gas industry especially in Offshore Engineering. The objective of this thesis is to establish the fundamental principles and address the main issues in the development of a Collaborative Environment for Engineering, named CEE (Collaborative Engineering Environment), in order to allow the collaborative visualization and interpretation of simulation results produced in engineering projects, which in general also involve different specialties. Due to the multidisciplinary characteristic of those projects, collaborative visualization becomes a key component during the life cycle of engineering projects, especially those in Offshore Engineering, used in this work as case of study. We propose an integrated collaborative environment to be used by project engineers teams during the execution and control of complex engineering projects, as is the case of the projects of deep-water floating production units. The system requirements were carefully compiled aiming to enable an effective collaboration among the participants, creating a suitable environment for discussing, validating, interpreting and documenting the results of the simulations executed during the different phases of an engineering project. To further improve the interpretation capacity and a better comprehension of results the support for immersive 3D visualization is also available in the visualization tool, especially tailored for the Offshore Engineering domain. In order to meet these goals, we devise a Service- Oriented Architecture (SOA) for CEE. This architecture is composed of the integration of different technologies of Computer Supported Collaborative Work (CSCW), Virtual Reality (VR) and Grid Computing (GC). We use a Scientific Workflow Management System (ScWfMS), based on BPEL (Business Process Execution Language), a Grid-enabled software infrastructure for executing engineering simulations, and a Video Conferencing system (VCS) to furnish audio and video collaboration. For visualizing the results, a VR visualization tool, specialized for Offshore Engineering, ENVIRON, has also been developed in conjunction with the PUC-Rio/TecGraf team.

Résumé :

Rehabilitation coatings of offshore equipment rarely perform as well as the original coating, despite the high cost involved. The performance gap is probably due to high relative humidity, salt contamination and limitations on the use of abrasive blast cleaning. Thus, this research aims to deepen the understanding of surface preparation parameters that affect organic coating performance. Carbon steel samples were subjected to a variety of surface alterations consisting of salt contamination, mechanical (wire brushing) and chemical (rust converter and remover) surface preparations followed by coating application and performance testing. The samples were first pre-corroded in a corrosion chamber to mimic degradation from service then surface preparations were performed after which a coating was applied. Coated new samples (RN) and fully corroded samples (SN) were the reference sets, while other samples were prepared to a variety of surface conditions. Visual inspection and electrochemical impedance spectroscopy (EIS) were performed prior to exposure and periodically during accelerated cycling corrosion testing for a period of 30 days. The visual condition of the samples was used to rank the performance of the prepared samples. These results were used as benchmark to decide the optimum EIS method, either phase angle at high frequency or total impedance at low frequency, for early evaluation of the organic coating performance under the conditions studied. Furthermore, adhesion pull-off testing was performed to rank the effectiveness of the coating over various prepared coating. The reference new samples (RN) proved to be the best surface condition and the corroded samples without preparation (SN) had the worst performance for all tests performed. In addition, it was established that salt contamination had a stronger impact on the coating performance than the amount of corrosion product remaining on the surface. Moreover, it was determined that the best preparation approach after precorrosion of the plates was to apply rust converter to the surface before coating. Adhesion measurement was of secondary concern on the studied coated surfaces as cohesive failure occurred on the pre-treatment layers rather than coating adhesion failure between the coating and the treated surface.

Résumé :

Navigation channels are periodically dredged to maintain safe depths. Dredged sediment was historically placed in upland management areas or in offshore disposal areas. Florida state law prohibits placement of beach fill sediment that contains more than 10% by weight of silt and clay, which is typically a characteristic of dredged material. An alternative is placement in a nearshore berm. Some potential benefits of nearshore berms include wave energy dissipation, reduced cost of dredging and shore protection, and possible onshore movement of the berm material. This study considers sediment distribution, morphological evolution, sediment transport, and shoreline trends along Fort Myers Beach, Florida, related to the nearshore berm constructed in August 2016. Due to timing of the field study, this report also includes information on the influence of a major hurricane that impacted the area. The overall conclusion of this study is that the dredge-sourced sediment in the berm performed as expected. Within 2 years, the berm adjusted to the shoreface environment, maintained a large part of its original volume, and contributed to protection of the beach and shoreline. The impact of Hurricane Irma included a shift in sediment textures and a large but temporary increase in shoreface sediment volumes.
