“海洋石油707”综合勘察船的总体设计

综合勘察船作为海洋油气田勘探的主力船型，具有钻探取样、海洋水文调查和海底地形地貌勘察等多种功能。简要介绍某综合勘察船的主要技术特点、总布置特点、船舶性能和船舶定位系统设计等。为提高舒适性，该船对上层建筑布置进行优化，满足《2006年海事劳工公约》的要求；为提高作业能力，该船布置钻机系统、单波束、多波束、浅剖和海流剖面仪等大量专业设备；为兼顾深水和浅水的定位能力，该船配备动力定位系统和四点锚泊系统。耐波性和稳性作为关键性能，将直接影响勘察船的作业能力，在对该船进行设计时采取一系列措施提高其作业能力。为保证该船的稳性和装载能力，空船重量控制也是重点工作。

General Design of the Multi-Functional Survey Vessel Hai Yang Shi You 707

As a major ship type of offshore oil and gas exploration, Multi-functional survey vessel has the functions of sample boring, oceanographic investigation and geotechnical exploration. This paper briefly introduces the technical specifications, the general arrangement, the performance and the positioning system of the multi-functional survey vessel. The superstructure of the vessel has been optimized for comfortability to meet the requirement of MLC2006. Some professional devices are equipped to improve the operation capability, including the drilling system, single-beam/multi-beam sub-bottom profiler and current profiler. The dynamic positioning system and four-point mooring system provide the ship with the positioning ability both in deepwater and shallow water. Besides, a series of measures have been taken to improve the ability of the ship as the sea-keeping ability and stability of the ship directly influence the survey operation. Light weight control is also one of the key considerations to guarantee the stability and loading capacity.
