| The Polarled pipeline has crossed the Arctic Circle  On Friday 21 August, Statoil's Polarled gas pipeline crossed 66 degrees and 33 minutes north of the equator becoming the first subsea pipeline to take the Norwegian gas infrastructure across the Arctic Circle. Ramboll designed the pipeline which will open a new gas highway from the Norwegian Sea to Europe.The 482-kilometre Polarled pipeline will run from the Aasta Hansteen field in the Norwegian Sea to the Nyhamna gas terminal in western Norway. Moreover, the pipeline is setting world record for deep water installation of a 36-inch pipeline. Ramboll started working on the FEED for the Polarled pipeline in 2012, and continued with detailed design starting in January 2013, which continued until February 2015. Furthermore, Ramboll's environmental specialists assisted with environmental impact assessment. Currently Ramboll is providing engineering services for the follow-on phase. The world's largest pipelaying vessel, Solitaire from Allseas, is carrying out the job and is advancing steadily. The line pipes each being 12.2 m long are welded together on-board the pipelaying vessel. On average 300 - 400 pipe joints are welded together per day, equivalent to a production rate of an amazing 3.5 to 5.0 km/day of pipeline installed on the seabed. A long and challenging journey is coming to an end Ramboll project manager Lars Eriksen is thrilled to see the pipeline project being realised. - It has been a long and challenging journey from FEED design, through detailed design and now during the construction phase, and it is very satisfactory to see the various parts of the projects coming together. After crossing of the Arctic Circle, the majority of the Polarled pipeline has been installed successfully in accordance with our design. The Polarled design team has done an excellent engineering job and contributed to significant cost savings for the client. We are all very proud to be part of such an important pipeline project. write your comments about the article :: © 2015 Construction News :: home page |
