内转塔式单点系泊系统设计方法研究   总被引：1，自引：0，他引：1  

白雪平  李达  范模  易丛  邹星 《海洋工程》2015,33(3):36-42

以南中国海恩平24-2油田开发工程为背景,针对南中国海海域恶劣环境条件,提出了新建单点系泊系统的总体方案规划与设计方法,为工程总承包(EPCI)提供技术支持,并确定了适用于恩平24-2油田开发的单点形式——带解脱装置内转塔式永久单点系泊系统。首先针对恩平24-2油田海域特征,规划出最适宜的单点总体布置,然后根据油田环境参数,提出了内转塔式单点系泊系统(包括浅水系泊系统、动态立管和动态电缆)的设计方法并对其系泊系统进行分析。研究结果可以看出内转塔式单点系泊系统设计方法对于环境恶劣海况下的单点设计具有指导意义,并能为国内单点的技术发展积累设计经验。  相似文献

Aims and Scope
Being an international journal, China Ocean Engineering takes as its prime function the integration of new research concepts, equipment, technology, materials and structures and other scientific advances within the field of estuarial, coastal, offshore, and deepwater engineering with particular reference to developments. The Journal is concerned with all engineering aspects involved in the exploration and utilization of ocean resources. Topics regularly covered include research, design and construction of structures （including wharfs, dikes, breakwaters, platforms, mooring systems, etc.）, instrumentation/testing （physical model and numerical model）, wave dynamics, sedimentation, structural/stress analysis, soil mechanics, and material research.  相似文献   

LH11-1半潜式平台的船体-系泊系统测量     

屈衍  杜宇  武文华  时忠民  岳前进 《海洋工程》2013,31(6):1-8

深水海洋平台的现场监测是对平台性能的直接评估,对保障平台安全,改进平台设计方法等具有重要意义。介绍在南海LH11-1平台上开展的现场监测工作,内容包括海洋环境、平台运动以及系泊系统测量。对平台在洛坦台风中的运动响应进行了测量结果与分析结果的比较分析。结果表明数值分析结果与测量结果部分吻合,但仍有差异,测量结果的波频分量大于计算结果,但计算的精度在可接受的范围内。  相似文献

During the summer of 2008, the third CHINARE Arctic Expedition was carried out on board of Xuelong Icebreaker in the central Chukchi Sea. A submersible mooring system was deployed and recovered at Station CN-01 (71°40.024′N, 167°58.910′W) with 33 days of the current profile records, and continuous observation of temperature and salinity data were collected. This mooring station locates in the blank of similar observation area and it is the first time for our Chinese to finish this kind of long-termmooring work in this area. Thismooring systemfinished integrated hydrological observationswith long-termcontinuous record of the whole profile velocity for the first time. Based on time series analysis of temperature, salinity, velocity and flow direction, we get the following main results. (1) During the observation period, the mean surface current velocity is 70.2 cm/s eastward, and velocity reaches itsmaximumin average at 3mlevelwithmagnitude 90.0 cm/s, direction 206°. (2) In 9-30mlayers, the semidiurnal period variationis themost obvious, the flow direction is quite stable, and the flow is synchronous and consistent vertically. (3) Besides the semidiurnal period variation, the main variation in the upper layer is in 11-d period, with variations in period 5.5, 5.5, and 3.7 d, which reflect the influences of sea surface wind change and maintenance. (4) Near the bottom, the temperature change is correlated and synchronizedwith the conductivity.  相似文献

Shallow Water Effects on Surge Motion and Load of Soft Yoke Moored FPSO   总被引：2，自引：0，他引：2  

肖龙飞  杨建民李欣 《中国海洋工程》2007,21(2):187-196

Much attention should be paid to a large FPSO moored permanently in an oil field with water depth of only about 20 m, since shallow water effects on the hydrodynamics may bring about collision and damage. A 160kDWT FPSO with a permanent soft yoke mooring system is investigated with various shallow water depths and focuses are the low frequency surge motion and mooring load. Computation for the FPSO system is made based on linear 3-D potential fluid theory and time-domain numerical simulation method. Corresponding model test is carried out in the ocean engineering basin of Shanghai Jiao Tong University. It is shown that, in the surge natural period, low frequency surge motion and mooring force increase remarkably with the decrease of water depth. Especially, the smaller the ratio of water depth and draught is, the quicker the increase is. The shallow water effects should be taken into account carefully for determining the design load of a single point mooring system.  相似文献
