摘　　要：海底管线终端设备(PLET)是深水水下油气田开发的核心设备,其关键技术长期被国外垄断。为了掌握深水海底管线终端设备的设计、制造、测试及安装关键技术,实现该产品的完全国产化,根据深水海底管线终端设备的应用特点,依托我国南海某气田示范工程项目,完成了500 m水深级分体式海底管线终端设备的设计和工程样机的研制。在完成常规陆地测试的基础上,结合我国南海海域的环境条件,在330 m水深的陆丰海域进行了海上安装和实海功能测试。测试结果表明:ROV可以清晰读取工程样机上数字、字母及阀门的开关位置指示,水下阀门ROV操作顺利,开关位置指示准确,阀门整体功能完善;深水分体式PLET工程样机两侧锁臂的开关销操作方便,两侧锁臂能够正常开关;PLET本体能够正确就位于防沉板基础内,且管线部分不发生倾斜;PLET本体从防沉板基础中脱离、回收至甲板均不存在障碍,各项测试结果均满足设计的指标要求。研究成果对深水海底管线终端设备及其他深水水下生产设施的技术研究和产品研制均具有重要的借鉴意义。The PLET is the core product of deep-water oil and gas field development,whose technologies have long been monopolized by foreign countries.To master the key technologies for the design,manufacture,testing and installation of deep-water PLET and realize the complete localization of the product,according to the application characteristics of deep-water PLET,relying on the trial project of a gas field in the South Sea of China,a split PLET engineering prototype for water depth 500 m is designed and developed.After completing the conventional land test,considering the environmental conditions of China’s South Sea area,offshore installation and function test are carried out in the 330 m water depth of Lufeng sea area.The test results show that the ROV can clearly read the numbers,letters and valve switch position indications on the engineering prototype.The underwater valve is smoothly operated by ROV.The switch position indication is accurate,and the overall valve function is complete.The switch pins of the lock arms on both sides of the deep-water PLET engineering prototype are easy to operate.The lock arms on both sides are normally opened and closed.The PLET body can be correctly located in the anti-sinking board foundation,and the pipeline part does not tilt.The separation from the anti-sinking board foundation and recovery to the deck of the PLET body is smooth.All test results meet the design index requirements.The research results have important reference significance for the technical research and product development of deep-water PLET and other deep-water production facilities.
