| 1 | Floating production storage and offloading systems' cost and motion performance: A systems thinking application显示文摘Floating production storage and offloading(FPSO) units increasingly represent a practical and economic means for deep-water oil extraction and production. Systems thinking gives a unique opportunity to seek a balance between FPSO technical performance(s),with whole-cost; stakeholder decision-making is charged to align different fit-for-use design specification options' that address technical-motion(s), with respective life-cycle cost analyses(LCCA). Soft system methodology allows situation based analyses over set periods-of-time by diagnosing the problem-at-hand; namely, assessing the antecedents of life-cycle cost relative to FPSO subcomponent design alternatives. Alternative mooringcomponent comparisons for either new-build hulls or refurbished hulls represent an initial necessary consideration to facilitate extraction, production and storage of deepwater oil reserves. Coupled dynamic analysis has been performed to generate FPSO motion in six degrees of freedom using SESAM DeepC, while life-cycle cost analysis(LCAA) studies give net-present-value comparisons reflective of market conditions. A parametric study has been conducted by varying wave heights from 4 – 8 m to understand FPSO motion behavior in the presence of wind and current, as well as comparing the motions of turreted versus spread mooring design alternatives. LCCA data has been generated to compare the cost of such different mooring options/hull conditions over 10 and 25-year periods. Systems thinking has been used to explain the interaction of problem variables; resultantly this paper is able to identify explicit factors affecting the choice of FPSO configurations in terms of motion and whole-cost,toward assisting significantly with the front-end engineering design(FEED) phase of fit-for-purpose configured FPSOs, in waters off Malaysia and Australia. | Rini NISHANTH Andrew WHYTE V.John KURIAN | 2018 | Frontiers of Engineering Management2018，5，3： | 0 |
| 2 | 考虑拆解的老龄固定式离岸平台条件评估技术的历史回顾显示文摘In this study,the technical papers on structural condition assessment of aged fixed-type offshore platforms reported over the past few decades are presented.Other ancillary related works are also discussed.Large numbers of researches are available in the area of requalification for life extension of offshore jacket platforms.Many of these studies involve reassessment of existing platforms by means of conducting pushover analysis,a static nonlinear collapse analysis method to evaluate the structure nonlinear behaviour and capacity beyond the elastic limit.From here,the failure mechanism and inherent reserve strength/capacity of the overall truss structure are determined.This method of doing reassessment is described clearly in the industry-adopted codes and standards such the API,ISO,PTS and NORSOK codes.This may help understand the structural behaviour of aged fixed offshore jacket structures for maintenance or decommissioning. | Mohamed Mubarak Abdul Wahab V.John Kurian Mohd Shahir Liew Do Kyun Kim | 2020 | Journal of Marine Science and Application2020，19，4： | 0 |
