Abstract:
Introduction. Statistical analysis of fires at storage, refining and transportation facilities for oil and petroleum products over the past 20 years shows that out of 200 fires, 92% of them occur in land tanks. In a fire, liquid combustion in the tank is a diffusion combustion of a jet of steam in the air. In the process of burning the liquid in the tank changes the mechanical properties of its metal wall, which affects its fire resistance duration. In the event of a fire in the tank, the drywall may be destroyed. Destruction of dry tank wall can lead to oil spills and cascading fire. Therefore, the main problem is to determine the fire duration before the destruction of the dry wall of the tank, i.e. its fire resistance.Purpose. Develop a method for determining the fire resistance of the dry wall of the storage tank of oil and petroleum products.Methods. To develop a method for determining the fire resistance of storage tank dry wall of oil and petroleum prod-ucts, it is necessary to solve the following problems:1) to determine the temperature effect on sheet material of tank dry wall on its strength;2) to obtain the dependence for determining the duration of time before the occurrence of ultimate destructive stresses of the sheet material of tank dry wall;3) to obtain the dependence for determining the time of fire resistance of tank dry wall of oil and petroleum products in the event of a fire.To solve the first problem, the temperature influence of the sheet steel used to make the tank wall on the yield strength σT was established.To solve the second problem, a dependence was obtained to determine the length of time before the occurrence of critical temperatures at which the destruction of the sheet material of tank dry wall is possible.To solve the third problem, a block diagram of the algorithm for determining the fire resistance of tank dry wall in case of fire was developed, on the basis of which a package of applications was developed.Conclusions and specific suggestions:1. The influence of the temperature of the sheet material of tank dry wall on its strength is established. The research results showed that the temperature of the tank drywall material in the range of 690-710 ºC is critical and it can lead to its destruction.2. The results of the research allowed to obtain the dependence for determining the duration of time to critical temper-atures occurrence at which the destruction of the sheet material of tank dry wall. The results of calculations for the tank RVS-5000 showed that its fire resistance varies within τv = 13…15 minutes. Of course, this value of fire resistance for tank dry wall is very small in terms of the fire extinguishing process. Therefore, it is necessary to develop and implement certain measures to increase the fire resistance of tank dry wall.3. To determine the time of fire resistance of tank dry wall storage of oil and petroleum products in the event of a fire was obtained dependence, which allows to determine the temperature T in ºC from the duration of burning the tank τ per minute, the height of the dry wall h0 in m upper edge. The research results allowed to develop a block diagram of the algorithm for solving this problem, as well as a package of applications based on it, which are written in the C # programming language.

Abstract:
The growth, production and survival of Nile tilapia Oreochromis niloticus, with an average individual weight of 0.2 g were used to determine the density-dependent growth and production relative to phytoplankton and periphyton biomass in periphyton-based aquaculture. The trial was conducted in 10 m2 concrete tanks for a 56 day period. A 10 cm layer of soil was placed at the bottom of each tank. To act as substrates for periphyton, bamboo poles with an approximate submerged surface area of 50% to that of the total tank surface area were vertically posted in the tank bottom. A weekly fertilizer dose of urea and triple superphosphate at a rate of 28 kg N and 7 kg P/ha/week was added. Four stocking densities in triplicate were used: 5, 10, 20, and 40 fish/m2 (50, 100, 200, and 400 fish/tank). The results indicated that the carrying capacity of periphyton-based tanks for Nile tilapia was 293 g/m2 in a 56-day culture period. The relationships between gross yields of tilapia (y) and periphyton dry matter (x), or chlorophyll a (x) were described as y = 353.2483-109.1809x, R2 = 0.5646, P = 0.005, y = 125.5916 + 0.9698x, R2 = 0.5841, P = 0.004. Provision of substrates at 50% of total tank surface area was sufficient for periphyton production in nutrient-rich aquaculture ponds where grazing rate and fish density in the system are balanced.DOI: http://dx.doi.org/10.3126/on.v11i2.9646 Our Nature 2013, 11(2): 105-115

Abstract:
People in the dry zone of Sri Lanka where hydraulic civilization once thrived, suffer from occurrence of a chronic kidney disease of unknown etiology (CKDu). The etiology for CKDu is now shown to be multi factorials and but related to water. Ancient people in the dry zone used surface water of tank cascades system and this system was interlinked with the ecosystem and social system of the area. It is hypothesized that the adverse changes that took place to the ecosystem of the tank cascade system and new commercial practices of agriculture in the CKDu prevalent area have also become reasons for the spreading of CKDu. This review assesses the effect of different components of the tank cascade systems in improving the water quality. A number of studies have reported positive effects of improving the surface water quality of the tank by the Wew Ismaththa (closer catchment), Thaulla (upper peripheral gentle sloping land), Kattakaduwa (Interceptor) Iswetiya or Potawetiya (upstream soil ridges), Godawala (small silt trapping pond). The review also identified functions of Thaulla area approximately similar to a constructed wetland. This review highlights the issues and gaps in our understanding the ecological functioning of Globally Important Agricultural Heritage System. It is suggested that reconstruction of ecofriendly structural components of tanks and reestablishment of tank cascade system in the area would help to combat the spreading of CKDu in dry and intermediate zone of the country.

Abstract:
The present work aimed to assess the partial replacement of artificial diets by wet bioflocs biomass in the culture of Nile tilapia juveniles. Fish were fed on different combinations of commercial dry diets (CD) and wet bioflocs biomass (BF), as it follows: 75% CD + 25% BF, 50% CD + 50% BF, and 25% CD + 75% BF, dry matter basis. There were also positive control tanks in which the fish received only commercial diet (100% CD), and three negative control tanks where the reductions of dry diets were not compensated by wet bioflocs biomass (75% CD, 50% CD, and 25% CD). Bioflocs were produced in one 500-L outdoor tank, which did not belong to the culture system, and it was called “separate BFT tank”, in which there was a daily adjustment of the C: N ratio of water to 15: 1, by the application of dry molasses to the water. There were no significant differences between the treatments for water pH, O2, TAN and NH3. Except by 25% CD, nitrite concentrations in water were lower in bioflocs tanks than in the artificial diet tanks. The final body weight of fish was significantly higher in tanks that received only dry diets (21.9 ± 6.4 g) than in tanks with a combination of 50% dry diet and 50% wet bioflocs biomass (10.4 ± 2.5 g; p < 0.05). It can be concluded that the impairment on the growth performance of tilapia submitted to feeding restriction is lessened if wet bioflocs biomass is provided to the animals. Besides, the total substitution of artificial diets for wet bioflocs biomass in clear-water tanks is unfeasible because it leads to higher rates of mortality of tilapia in a relatively short period.

Abstract:
Abstract Rainwater harvesting is an ancient practice aiming to cover water needs for domestic, irrigation and livestock uses. In this study, the rainwater harvesting tank size was investigated to meet five water-need levels of a mixed goat–sheep farm using a daily water balance method. This method was applied using daily rainfall data for a period of 16 years from six meteorological stations in selected regions of Greece, characterized by different rainfall regimes and well-developed livestock activity, taking into account, among other parameters, the water needs of animals, the rainwater collection area and the runoff coefficient. There is a great variation in the rainwater harvesting tank size among the stations studied due to differences in the annual rainfall and the maximum dry period. Results showed that meeting full demands (100% reliability) requires tank sizes ranging from 20 m3 for short dry period stations–low demand scenario (320 L/day) to 115 m3 for long dry period stations–high demand scenario (576 L/day), assuming a maximum collection area of 450 m2. Correspondingly, reliability analysis showed that very high values of reliability (95%) can be obtained with tank sizes ranging from 10 to 85 m3, respectively.

Abstract:
The current problem of the need to modernize the Russian fleet and, in particular, the power plants of ships, is caused by the decommissioning the most of the dry cargo and bulk carriers that are in using at this moment. Over time, most of these boards have ceased to be suitable for navigation and can not be repaired, and modern shipyards and shipyards are unable to use and service new ships designed for the domestic fleet. In view of this, there is a discrepancy between the number of required boards and the volume of orders from shipbuilders. The new brand of a foreign manufacturer's engines using on dry cargo and bulk ships of the previous generation significantly reduces the operating costs and repairing diesel engine’s costs, and also increases their service life. The comparison of the aggregates used at this moment and the model under consideration is made and a conclusion is made about the expediency of using the proposed engine for the purpose the Russian shipbuilding’s and ship repair’s long-term development. Subject: the study’s subject is the possibility of using foreign ships’ dry-cargo and tanker vessels for the modernization and improvement of the sides of the selected type.Materials and methods: in the work’s course is a comparative analysis of several types of diesel engines, possible for installation on the sides of the Volga-Don and Volgoneft, was carried out.Results: as a result of the work, a comparative table was developed for the characteristics of the diesel engine’s types under consideration, and the efficiency of using the considered brand’s foreign aggregates was revealed.Conclusions: the use of Yachai YC6CL diesel engines as powerplants on board dry cargo and liquid ships is advisable, because of their undeniable advantages in comparison with domestic units and economic feasibility.

Abstract:
The effects of Reynolds number (Re) and surface roughness on the wind pressure coefficient on a MAN type dry gas tank were analyzed in detail by wind tunnel tests. A wind load calculation model was then established, which is suitable for the wind resistant design of the gas tanks. The test results revealed that in the range of 7 × 105 < Re < 1.0 × 106 (supercritical regimes), the drag coefficient (Cd) and wind pressure coefficient remained constant, consistent with 2D cylinders in a uniform flow. However, in common with 2D cylinder flows, the surface roughness with the spacing ratio (λ) greater than 0.9 had a significant effect on the wind pressures coefficient. The minimum pressure coefficient (Cpmin) sharply increased from −2.3 to −0.65 with increasing surface roughness. The corresponding angle for the minimum pressure coefficient θmin was in between 140°and 90°, which was in a gradual decreasing trend with the increase in surface roughness of the model. The calculation method of the wind pressure coefficient with vary surface roughness was proposed, based on which, the calculation results were in good agreement with the test data.

Abstract:
This thesis presents an independent, sediment-based record of landscape change within an agricultural hinterland. Established historical and archaeological sequences document the primary occupation of Anuradhapura, Sri Lanka’s ancient capital, beginning ca. 400 BC and lasting until it was largely abandoned in AD 1017. Anuradhapura is located in the island’s dry zone, which depends almost completely on the unpredictable Northeastern Monsoon for water. Oral history and historical narratives have long held that large-scale irrigated rice cultivation took place in the hinterland to produce an agricultural surplus that sustained the urban and monastic populations. However, until the onset of the Anuradhapura Hinterland Project in 2005, the archaeological record of the hinterland was undocumented, leaving existing narratives untested. The geoarchaeological research presented here was undertaken as part of the Hinterland Project, in order to document the chronology and cultural and environmental processes that contributed to the formation of this irrigated landscape. Optical dating of sediments demonstrates that the onset of large-scale irrigation began ca. 400 BC, and the construction of new works continued until Anuradhapura’s late occupation period. Sampled reservoirs and channels began to infill, indicating widespread disuse, within ca. 100 years of Anuradhapura’s abandonment. Soil micromorphology and bulk sediment characterisation document hinterland habitation, water management, and cultivation activities prior to the establishment of large-scale irrigation. This work illustrates the coping strategies that people employed to deal with the vagaries of the dry zone environment and demonstrates that hinterland land use changed throughout the primary occupation period. Although largescale irrigation works infilled relatively rapidly, cultural activity and land use re-emerged following this period of disuse.

Abstract:
Nell'elaborato è stato proposto un confronto in termini di rischio tra sei differenti soluzioni tecnologiche applicate alla zona di stoccaggio di impianti per la gestione di gas naturale liquefatto (LNG). Si sono analizzate zone serbatoti con diverse tipologie di serbatoi tra cui single, double e full containment e differenti dimensioni e materiale del bacino di contenimento esterno. Sono state prese in considerazione anche le le tubazioni connesse ai serbatoi. Per svolgere il confronto si è scelto di sviluppare un'analisi di rischio. Come linee guida per l'analisi si è scelto di seguire le "Guidelines for Chemical Process Quantitative Risk Analysis", CCPS. La metodologia prevede una prima fase di definizione del sistema e di identificazione dei pericoli, per passare poi all'analisi delle conseguenze con relativa stima delle frequenze di accadimento dei guasti che danno origine ai rilasci di materiale pericoloso. Una delle fasi più importanti nell'analisi di rischio è senza dubbio la definizione degli scenari che possono generarsi in seguito all'innesco di un rilascio di sostanza pericolosa. Dopo un'attenta valutazione e valendomi del supporto tecnico di esperti del settore, sono state individuate prima le tipologie di rilascio (rottura di serbatoi e/o piping) e in seguito gli scenari incidentali principali (pool fire, flash fire, jet fire e vapor cloud explosion). Per il calcolo delle conseguenze e del rischio (espresso come frequenza annua di morte) è stato utilizzato Phast Risk 6.7, software in grado di calcolare intensità dell'effetto e probabilità di morte attorno alla sorgente di rilascio di materiale pericoloso. Le frequenze di guasto dei componenti (serbatoti, piping, valvole, flange e connessioni strumentali) sono state estratte a partire dall'analisi di alcuni database. I risultati trovati sono molto interessanti e mettono in luce l'importanza delle proprietà del materiale e delle dimensioni del bacino di contenimento esterno.

Abstract:
A produção de petróleo e gás em campos brasileiros é cada vez mais proveniente de regiões com águas profundas e situadas longe da costa, chegando a distâncias de mais de 100 km, como, por exemplo, na Bacia de Campos ou de Santos. Devido à falta de infra-estrutura e às características do petróleo desses campos, a cadeia de abastecimento e o sistema de exportação da produção possuem grande importância para a indústria offshore. Uma maneira usual para a exportação da produção é através de dutos submarinos, onde o óleo e/ou a gás flui das plataformas diretamente para o continente. Com esta infra-estrutura é possível a utilização de sistemas de produção sem capacidade de armazenamento e, conseqüentemente, torna-se desnecessário o uso de navios para o alívio da produção. No entanto, devido à qualidade do óleo e às distâncias entre os poços e a costa em alguns campos brasileiros, a utilização dos oleodutos mostra-se uma solução pouco viável. Por este motivo, é bastante comum o uso de FPSOs ou semi-submersíveis conectadas a sistemas auxiliares, como o FSO (Floating Storage and Offloading). Nas plataformas, outra característica importante e desejada é tornar viável o uso de um sistema de completação seca (árvore de Natal acima da linha dágua) com o objetivo de diminuir, significativamente, os custos operacionais envolvidos. Esse tipo de completação é utilizado, com excelência, por unidade do tipo TLWP ou Spar, devido ao baixo nível dos movimentos e acelerações observadas nestas plataformas. Entretanto, as condições ambientais severas amplificam as dificuldades para encontrar um sistema com grande capacidade de armazenamento e que permita o uso de completação seca. Neste contexto, pesquisadores e engenheiros estão sendo obrigados a desenvolver novos conceitos capazes de atender a essa demanda. Desta forma, uma nova solução, considerando um FPSO e uma TLWP operando a uma curta distância e trabalhando de forma acoplada com a conexão garantida por cabos sintéticos vem sendo estudada. Essencialmente, o grande atrativo deste conceito é o fato de que toda a produção e o armazenamento são concentrados no FPSO e a TLWP é responsável pela perfuração e extração dos hidrocarbonetos através de risers verticais. Assim o sistema trabalhando de forma conjunta possui capacidade de armazenamento e permite o uso da completação seca. Nesta dissertação, foi realizado um estudo sobre a evolução deste novo conceito, dividido em três fases. A primeira focada no dimensionamento do sistema de conexão e ancoragem das unidades e em uma investigação da interação hidrodinâmica entre as unidades de forma a mostrar a viabilidade do sistema. A segunda fase, focada na validação dos resultados por meio da comparação com os testes realizados no modelo em escala do NMRI (National Maritime Research Institute - Japão). Finalmente, a terceira fase, com foco no redimensionamento do sistema de amarração e no sistema de conexão, com base nos resultados obtidos na segunda fase.<br>The oil and gas production in Brazilian fields are commonly found in deep water and situated far away from the coast, reaching distances of more than 100 km as, for example, in the Campos Basin or Santos Basin. Due to the heavy oil and lack of pipeline infrastructure found in these fields, not only subsea equipments that must support high pressure but also logistics problems such as supply chain and production exportation system play an important role for the offshore industry. A usual way to export the production is to concentrate it in hubs of submarine pipelines which flows the oil or gas from the platforms to the continent. This infrastructure makes possible the use of no storage production systems and, consequently, releases the use of the shuttle tanks employment. However, due to the quality of the oil and the distances between the wells and the coast, some Brazilian fields do not allow the use of the pipelines to export their production. For this reason, is quite common to use FPSO and semi-submersible aided by auxiliary systems such as the FSO (Floating Storage and Offloading) units. Another important and desired characteristic of production platforms is to make it feasible to install a dry Christmas tree system aiming to decrease, significantly, operational costs involved. This feature is performed, with excellence, by TLWP and Spar units due to the low level of motions and accelerations observed in these platforms. Harsh environmental conditions can bring difficulties to find a solution of a system with both storage and dry tree system capability. In this context, researchers and engineers are being forced to develop new technological systems capable to support this demand. In this way, a new solution considering a FPSO and a TLWP coupled in a short distance by synthetic ropes has being studied. Essentially, the attractive feature of this concept is the fact that the production is performed by the FPSO whereas the TLWP is responsible to support the risers and drilling facilities turning the system coupled, equipped with a dry Christmas tree and with the possibility to storage the production. By now, the concept evolution has been divided in three phases. The first phase concerned about an advanced research focusing on the connection and mooring system development and the hydrodynamic interaction between the units and having in mind the verification of the concept feasibility. The second phase, concerned about the results validation by a comparison with scale model tests performed in the NMRI (National Maritime Research Institute Japan). Finally, the third phase, has the focus in the mooring and connection system resizing based on the results obtained on second phase.

In ASME 2013 15th International Conference on Environmental Remediation and Radioactive Waste Management. American Society of Mechanical Engineers, 2013. http://dx.doi.org/10.1115/icem2013-96359.

Full text
Abstract:
This study explores the development of a mechanical based system to retrieve single-shell tank waste at the Hanford site, located in Richland, Washington, without the addition of water. Out of 177 tanks at Hanford, there are 149 single-shell tanks (SST) and 28 double-shell tanks (DST). There are currently 67 SSTs that have leaked radioactive waste to the surrounding groundwater in the past or assumed to have questionable tank integrity. Leaking tanks continue to be a major concern as it was recently announced in February 2013 that six SSTs are leaking, even though they were believed to have been stabilized back in 2005. There are also several tanks with significant in-tank obstructions, such as air-lift circulators, where an arm-based retrieval would not be possible. All current methods of waste retrieval deployed involve the addition of significant amounts of water to generate a slurry that can be pumped out of the tank. This water, however, can exacerbate the leak and risk the potential of leaking more waste into the surrounding soil, subsequently contaminating the groundwater. It also reduces available waste storage space in DSTs, and increases the risk of dangerous buoyant displacement gas release events (BDGRE) in the headspace of DSTs. Focusing on leaking tanks, tanks with significant in-tank obstructions, and utilizing existing risers in Hanford’s tanks, this study evaluates commercially available dry technologies, such as augers and high-powered vacuums, for feasibility, safety, and efficiency of waste retrieval at Hanford.

Full text
Abstract:
A low decay heat (implying Spent Fuel (SF) pebbles older than 8–9 years) bulk dry storage section is proposed to supplement a 12-tank wet storage section. Decay heat removal by passive means must be guaranteed, taking into account the fact that dry storage vessels are under ground and inside the building footprint. Cooling takes place when ambient air (drawn downwards from ground level) passes on the outside of the 6 tanks’ vessel containment (and gamma shielding), which is in a separate room inside the building, but outside PBMR building confinement and open to atmosphere. Access for loading / unloading of SF pebbles is only from the top of a tank, which is inside PBMR building confinement. No radioactive substances can therefore leak into atmosphere, as vessel design will take into account corrosion allowance. In this paper, it is shown (using CFD (Computational Fluid Dynamics) modelling and analytical analyses) that natural convection and draught induced flow combine to remove decay heat in a self-sustaining process. Decay heat is the energy source, which powers the draught inducing capability of the dry storage modular cell system: the more decay heat, the bigger the drive to expel heated air through a higher outlet and entrain cool ambient air from ground level to the bottom of the modular cell.

Full text
Abstract:
Truss Spars that are designed to accommodate dry transportation encounter certain constraints because the overall length and hard tank diameter of the Spar cannot exceed the limits of the transport vessel. When these constraints are removed, hulls can be longer. Increased length allows the fixed ballast and hard tank steel weights to be reduced. Although the truss steel weight is increased for deeper drafts, there is an overall savings in steel when the hard tank and soft tank are taken into account. The heave response of a Spar can be adversely affected by tensioners used to support TTRs. Deeper drafts can improve heave response and an additional heave plate can be introduced if necessary.

Full text
Abstract:
In this paper the performance of a new conceptual semisubmersible design that provides motion response similar to a Spar is investigated. The new invention introduces a new feature which is the Free-Hanging Solid Ballast Tank, hence the name FHS Semi. The use of the free-hanging Solid Ballast Tank (SBT) significantly increases the heave natural period while controlling the heave response in the wave frequency range and, therefore, enables the use of the FHS Semi in dry tree applications. The new design’s quayside integration technique and its interface with the top tensioned risers are presented in this paper. Case study for the new design to support a 32,000 ST payload including 15 Top Tensioned Risers (TTRs) in an ultra-deepwater of 8,000 ft water depth is considered. Frequency domain and fully coupled time-domain hydrodynamic analyses have been performed and numerical results are presented to illustrate the new semisubmersible design response in extreme Gulf of Mexico hurricane events.

Full text
Abstract:
The net working capacity of floating roof tanks is the product inventory that is stored between the maximum and minimum operating levels of the floating roof. The product that remains in the tank when the floating roof is at its minimum operating level is residual inventory, referred to as the product heel. This trapped inventory is a valuable product asset that is not part of the tank net working capacity. This paper describes considerations that must be made when lowering the minimum operating level of floating roofs, both for new and retrofit tank applications, and presents methods of achieving these improvements. Some tank turnover operations require that the floating roof be landed and the tank drained dry. Tank turnover operations include those where it is important to avoid cross contamination of products. Recent studies have shown the importance of the emissions that occur during heel turnover operations. This paper describes a method for determining the heel turnover emissions and presents abatement options for controlling these emissions.

Full text
Abstract:
Corrosion is the key factor responsible for the degradation of ship structures and in no place is this truer than water ballast tanks. Coating protection system is a continual research interest for classification societies and coating industries. Up to now, most coating performance analyses are qualitative not quantitative. Coating life prediction is almost always based on experience and various assumptions, due to unavailability of practical data support systems. This paper describes a preliminary impartial investigation of coating life carried out with interviewees from the Australian Defence Science and Technology Organization (DSTO), shipyards, coating supplier and an independent expert. Plate surface, edges and welds in ballast tank were considered and the influences of dry film thickness (DFT) and surface preparation (SP) are addressed. The investigation gives some insight into the life of practical coating systems for water ballast tanks. Coating life is proposed to be representable by a normal distribution when corrosion breakdown is below 10% of plate thickness, which is of practical implication.

Abstract:
Abstract Petroleum product needs to be stored and transported from various sources before they get to the final consumers, there by requiring storage tanks. Calibration of storage tank by dry and wet strapping process have evolved over the years with state-of-the-art facilities. The calibration charts are used to determine and know the volume of fluid in a tank given the height of the petroleum products stored in the tank. Calculating volume of a tank with the integration method has a lot of sources of error thereby affecting the result of the volume calculated and causing losses in revenue due to inaccurate calibrated tanks. With the losses in revenue due to wrong computations or computational errors, a fast, dynamic and cost-effective solutions become imperative to solve these computation problems. The tank charts having been delivered for daily usage and fiscalization process after the tank strapping process, calculation errors need to be minimized in order to report accurately petroleum products in stocks, which is a function of temperature, density and volume correction factor. This paper aims to solve the problem by semi automating the process of calculating total volume of product in stock with error free results. Approach in this paper was used and test run for a storage facility X. This paper shows how calculations from calibrated tanks can be done with a virtual method using excel spreadsheet and converted into a software for effective use and making percentage error almost zero. The results obtained from this method of computation were error free and devoid of human errors.

Abstract:
The dry tree production and drilling Top Tensioned Riser (TTR) systems have been extensively used with Tension Leg Platforms (TLPs) and Spar floaters in deepwater applications. However, the large heave response of the conventional Semisubmersible floaters makes this type of platforms not suitable for dry tree applications largely due to the ultra-long stroke tensioner that would be required in this case. The Free Hanging Solid Ballast (FHSB) Semi is an innovative new semisubmersible design that is suitable for dry tree applications due to its low heave response that is comparable to that offered by Spar floaters. The new design resembles the conventional Semisubmersibles with an added free-hanging solid ballast tank placed deep below the keel of the Semisubmersible hull and connected to the hull through four groups of chains. The Solid Ballast Tank (SBT) acts as a motion damper that significantly improves the heave motion response. In this paper, the design of the dry tree TTR system for the FHSB Semi is presented. The typical GoM’s drilling and production conditions are used in designing the TTR system including the tensioning system and the interface between the SBT and the riser keel joint. The feasibility and performance of the designed TTR system are demonstrated through static and dynamic TTR analyses.
