海洋管集束技术特点与应用分析

Technical characteristic and application analysis of pipeline bundle

海洋管集束(以下称“管集束”)系统由承载管、护管、油气液输送管线、电缆和拖拉头等结构组成,是一种将功能各异的管线集束在一起,在陆地完成预制、组装和测试后,拖航至海上油田现场进行定位与安装的新型油气集输形式。其工期、质量、造价、保温性能及机械性能较传统海底管线优势明显。针对管集束的特点,对其设计、制造、安装和费用情况进行介绍,与传统管道进行对比分析,同时对其在中国海洋油气开发的运用前景进行了展望。

Pipeline bundle(refer as“bundle”)system consist of carrier pipe[1],sleeve pipe,flowlines,umbilical and towhead,etc.It is a new type of oil and gas transportation system through gathering all pipelines with different functions,onshore prefabrication,assembly,commissioning then towing to the offshore field for positioning and installation.Comparing with the conventional pipeline[2],bundle has the transparent advantages in construction period,quality guarantee,cost,insulation and mechanical property.This article gives a characteristic introduction about bundle’s design,fabrication,installation and cost,makes comparison with conventional pipeline,also makes an expectation of using in China seas.
