Latest developments and news from the pipeline industry

POLARLED REPORTS FIRST EUROPEAN PIPELINE EVER TO CROSS THE ARCTIC CIRCLE In an unprecedented feat of engineering for the Polarled project the first pipeline crossing the Arctic Circle was laid by a consortium of Statoil - led companies. The Polarled gas pipeline crossed 66 degrees and 33 minutes north of the equator becoming the first pipeline to take the Norwe- gian gas infrastructure across the Arctic Circle. This will open a new gas highway from the Norwegian Sea to Eu- rope. The 482-kilometre long and 36-inch wide pipeline will run from Nyhamna in western Norway to the Aasta Hansteen field in the Norwegian Sea. The world’s largest pipelaying vessel, Solitaire from Allseas, is carrying out the job and is advancing slowly, exactly 24.4 metres at a time, every sixth minute or so, around the clock. During the start-up in March the pipeline was pulled in to Nyhamna. During September the vessel will arrive at the Aasta Hansteen field, if weather permits. Even early in the autumn high waves and strong wind leading to interrup- tions must be expected. The weather has been good for a long period now: «We are progressing well at the moment, conditions have been good for more than 50 days in a row, and at the end of July we set a record of laying 4.8 kilometres of pipes in one day,” says Kenneth Aksel Kristensen, one of Statoil’s company representatives on board the vessel. Pipeline installation is taking place at water depths reach- ing 1265 meters and this is the first time a 36-inch wide pipe is laid in such deep waters anywhere in the world. Polarled is expected to begin shipping gas to Europe this autumn. GENERAL ELECTRIC REELS IN BIG CONTRACT WITH TRANS-ANATOLIAN NATURAL GAS PIPELINE (TAN- AP) PROJECT General Electric (GE) has secured a multi-million dollar contract to pro- vide advanced turbo machinery for the Trans-Anatolian Natural Gas Pipeline (TANAP), facilitating the transport of natural gas from Azer- baijan via Turkey to European energy markets. The gas turbines bring high levels of operational efficiency and low emission levels. These critical systems are seen to be the “heart of the pipeline.” GE reports that gas turbines will be manufactured and tested at the GE Oil and Gas for shipment to Turkey in 2017. Rami Qasem, President & CEO, GE Oil & Gas MENAT, said: “We are pleased to be providing technologically advanced GE O&G solutions for the prestigious TANAP project and building partnerships and trust with SOCAR, BOTAŞ and BP. This marks a key milestone for GE Oil & Gas and underlines our long-term commitment to Turkey where GE has been driving several localization initiatives as part of its US$900 million investment announced in 2012 in support of Turkey’s Vision 2023.” For further information: GE Oil & Gas Media Relations For further information: Morten Eek, Statoil It takes six boat in shuttle traffic to keep the two cranes on Solitaire sup- plied with pipe around the clock (Photo: Eva Sleire, Statoil ASA) GE Oil & Gas to provide advanced turbomachinery for landmark TANAP project INDUSTRY AND PRACTICE 14 PIPELINE TECHNOLOGY JOURNAL
