石油设备网讯 据世界能源新闻网2019年4月19日伦敦报道，北溪-2天然气管道的1000公里长的钢管目前已在波罗的海的芬兰、瑞典和德国三国海域完成铺设作业。
国际著名海洋承包商Allseas旗下的两艘管道铺设船——《Pioneer Spirit》号管道铺设船和《Solitaire》号管道铺设船——时下正在瑞典海域铺设管道。
目前大约有20艘船在波罗的海从事这个项目，有近1300人在管道铺设船、管子供应船和勘测船上工作。
上周，这个项目的涂层和物流承包商Wasco也达到了另一个里程碑，在其在芬兰科特卡(Kotka)厂中完成了其钢管份额的混凝土加重涂层，在那里，大约有10.1万根钢管被涂上保护层。这相当于北溪双管道系统所需钢管的一半。
北溪双管道系统由两条长约1230公里的天然气管道组成，每条天然气管道由大约10万根钢管焊接而成。
北溪- 2是一条计划通过波罗的海的天然气管道，从俄罗斯的世界最大天然气储量出发，通过最有效的途径把天然气输送到欧洲消费者手中，全长大约1230公里。北溪-2天然气管道项目将在很大程度上遵循成功的北溪天然气管道的路线和技术概念。

1000 Km of the Nord Stream 2 Pipeline Laid
1000 km of the Nord Stream 2 pipeline has now been laid in the Baltic Sea in Finnish, Swedish and German waters.
Two Allseas pipelay vessels - Pioneering Spirit and Solitaire - are currently installing the pipeline in Swedish waters.
Some twenty vessels are currently being engaged in the project in the Baltic Sea, with nearly 1,300 people working on board the pipelay, pipe supply and survey vessels.
Another milestone was also reached last week, when the project’s coating and logistics contractor Wasco completed concrete weight coating of its share of the steel pipes in its plant in Kotka, Finland, where approximately 101,000 steel pipes had been coated.
This corresponds to half of the pipes needed for the twin pipelines.
The twin pipeline system consists of two approximately 1,230-kilometres-long pipelines, each made up of some 100,000 pipe joints.
Nord Stream 2 is a planned pipeline through the Baltic Sea, which will transport natural gas over some 1,230 km from the world’s largest gas reserves in Russia via the most efficient route to consumers in Europe. Nord Stream 2 will largely follow the route and technical concept of the successful Nord Stream Pipeline.
