深水钻井船波浪载荷研究及总强度分析

Research on wave load and total strength of deep-sea drilling ship

深海钻井船作为一种兼具试采、储存和油气处理能力的高端海洋工程装备,可在中国南海等多区域进行作业工作。但是深海区域海洋环境条件恶劣,油气资源开发难度高,针对深海钻井船这一特殊船型,利用挪威船级社(DNV)SESAM软件进行波浪载荷研究,并结合相关规范进行有限元强度分析,结果符合设计要求,可为今后相关船型设计提供依据,具有一定的工程意义。

With the increasing demand for oil and the increasing pressure of energy supply in the world,the proportion of existing oil reserves is increasing,which requires further exploration of new oil resources.Offshore oil and gas has attracted the attention of all countries because of its abundant reserves.As a kind of high-end offshore engineering equipment with test production,storage and oil gas processing capacity,deep-sea drilling ship can operate in the South China Sea,West Africa and other regions.In the future,it will become an important tool for China’s far-reaching development of offshore oil and gas.However,the deep-sea area has rough environment conditions,and it is difficult to develop oil and gas resources.Aiming at the special ship type of deep-sea drilling ship,this paper studies the wave load by using the software SESAM,and does the finite element strength analysis combined with the relevant specifications.The results meet the design requirements,which can provide the basis for the future design of relevant ship types.
