南海FLNG上部模块总体布局方案研究 总被引:1,自引:0,他引:1
FLNG在南海深水气田开发中应用前景广阔,应加强对其设计技术的研究.本文结合调研和项目经验,总结FLNG上部模块总体布置原则和规范,研究布局影响因素,并提出南海FLNG布局建议.FLNG上部模块设计时,应符合安全、经济、合理的原则,并遵守船级社和本行业在总体、工艺、安全等方面的规范;在选择布局方案时,应重点考虑系泊、外输、解脱、工艺方案等4个因素的影响;对于南海FLNG总体布局方案,采用旁靠时建议按从船首到船尾"单点-火炬-预处理-液化-外输-电站/公用-生活楼"布局,采用尾靠时建议按"生活楼-单点-电站/公用-预处理-火炬-液化-外输"布局.本研究成果可以为今后开展南海FLNG上部模块设计提供参考. 相似文献

This work details the simulation of tsunami waves generated by seaquakes in the Manila Trench and their effect on fixed oil and gas jacket platforms in waters offshore North Borneo. For this study, a four-leg living quarter jacket platform located in a water depth of 63 m is modelled in SACS v5.3. Malaysia has traditionally been perceived to be safe from the hazards of earthquakes and tsunamis. Local design practices tend to neglect tsunami waves and include no such provisions. In 2004, a 9.3Mw seaquake occurred off the northwest coast of Aceh, which generated tsunami waves that caused destruction in Malaysia totalling US$ 25 million and 68 deaths. This event prompted an awareness of the need to study the reliability of fixed offshore platforms scattered throughout Malaysian waters. In this paper, we present a review of research on the seismicity of the Manila Trench, which is perceived to be high risk for Southeast Asia. From the tsunami numerical model TUNA-M2, we extract computer-simulated tsunami waves at prescribed grid points in the vicinity of the platforms in the region. Using wave heights as input, we simulate the tsunami using SACS v5.3 structural analysis software of offshore platforms, which is widely accepted by the industry. We employ the nonlinear solitary wave theory in our tsunami loading calculations for the platforms, and formulate a platform-specific risk quantification system. We then perform an intensive structural sensitivity analysis and derive a corresponding platform-specific risk rating model. 相似文献

The past quarter of a century has brought with it significant change in the field of port management, both in terms of the goals that are set and the tools used. This trend has resulted in increased pressure on port authorities. The purpose of this paper is to deal in greater detail with developments in this area of port economics. 相似文献
