据8月26日Offshore Energy 报道，Nord Stream 2 AG公司在波罗的海的俄罗斯、芬兰、瑞典和德国水域铺设了长达1855公里的海上天然气管道，这相当于管道双线总长度的75%。

Nord Stream 2 AG是俄罗斯天然气工业股份公司(Gazprom)的子公司，也是该项目的运营商。该公司周一表示，该项目剩下的工程将在下一季度继续实施。

北溪2号设计为两条平行的48英寸长的线路，大约1200公里长，管线从圣彼得堡西南部开始，在德国海岸格赖夫斯瓦尔德结束。北溪2号天然气管道每年将有能力向欧盟输送550亿立方米（bcm）的俄罗斯天然气，输送时间至少为50年。

在德国领海和芬兰水域，这两条线都已完成施工。管道工程目前正在俄罗斯海域进行。在德国和俄罗斯的陆上地区，建筑工程已经进入关键阶段。

相关人员介绍，双管系统所需的所有管道均已涂有混凝土重量涂层，后勤业务已接近完成。

8月初，赛塞浦路斯的管道铺设船Castoro10开始在德国鲁根附近作业，将去年铺设在海床上的北溪2号管柱的两端连接起来。

今年夏天，在汉科、芬兰和瑞典卡尔沙姆，最后一批管道被装载到铺管船上。储存和物流作业分别在芬兰和德国的枢纽Kotka和Mukran继续进行。

Three quarters of Nord Stream 2 offshore pipeline laid

Nord Stream 2 AG has laid 1,855 kilometers of the offshore gas pipeline in the Baltic Sea in Russian, Finnish, Swedish, and German waters. This corresponds to 75 percent of the overall length of the twin pipeline.

Nord Stream 2 AG, a subsidiary of Russia’s Gazprom and the operator of the project, is proceeding with implementing the remaining quarter of the project, the company said on Monday.

Nord Stream 2 was designed as two parallel 48 inch lines, roughly 1,200 kilometers long, each starting from south-west of St Petersburg and ending at German coast, Greifswald. Nord Stream 2’s natural gas pipelines will have the capacity to transport 55 billion cubic meters (bcm) of Russian gas a year to the EU, for at least 50 years.

Both strings have already been completed in German territorial waters and Finnish waters. Pipelay is currently ongoing in Russian territorial waters. At the landfalls in Germany and Russia, construction works have reached an advanced stage.

According to the operator, all pipes needed for the twin pipeline system have been concrete weight coated. Logistics operations are nearing completion.

Earlier in August, Saipem’s pipelay vessel Castoro 10 started the work off Rügen, Germany to tie together the two ends of a Nord Stream 2 pipe string laid last year on the seabed.

In Hanko, Finland and Karlshamn Sweden, the last pipes were loaded out to pipelay vessels during this summer. Storage and logistics are continuing in the Finnish and German hubs, Kotka and Mukran, respectively.
