CHANGE OF ROLE: TurkStream sees Pioneering Spirit in pipelaying mode for the first time, with underwater stinger and its transition frame now suspended in bow slot while the heavy-lift beams on either side mostly take it easy.

Floating 30 kilometres out from the coast in 350 metres of water, the ship picked up and connected to the end of the shore approach section (laid in early summer by Allseas vessel Audacia), and started its deepwater mission straight off down the continental slope. Over the following 11 weeks the vessel went on to install 200 kilometres of Line 1 before laying the end down in a depth of 2170 metres at the edge of Russian waters. By mid-September, Pioneering Spirit was back inshore, picking up the second line and heading off south-west again, parallel to Line 1 and generally about 300 metres from it. This journey will continue for 870 kilometres until a laydown near the Turkish coast in May next year. Edward Heerema appears delighted with the way Pioneering Spirit has been shaping up as a pipelayer. The vessel has laid roughly 245 kilometres of TurkStream so far, he said at the start of October. Yesterday we reached a peak of 4.6 kilometres, our best daily rate yet. Every week is getting a little better, he added. We will surpass our current best daily rate, I just dont know how often. Of course the average is a lot less because you have days with bad luck. So far the average has been about 2.6 kilometres a day. All in all, the ship and its equipment have been behaving completely up to expectations, said Heerema. Frankly, it is fantastic to get such performance so quickly with a ship that is completely new. Teething problems can never be avoided, but there have been no major surprises on this front. The vessels DP stationkeeping is reported as excellent, not least when laying down the Russian slope. At some points the line had to be placed in a corridor just two metres wide. Behaviour in bad weather is earning plaudits as well. Weve had days that were so stormy that no support vessel could come near the ship, and still we continued laying pipe, said Heerema. Allseas client also appears satisfied. We are pleased to see that Pioneering Spirit is progressing in line with our schedule, says Jay Chaudhuri, project manager for Gazprom company South Stream Transport (SST) in Amsterdam, although it is too early for us to evaluate the performance in detail. technology The magazine for oil & gas innovators Issue 4 2017 Signs of life Charting a new course for floating production Joint efforts: Pipelay giants tackle the tough jobs Subsea solutions: Tapping technology to improve tie-back economics Produced and distributed by ready for the resource revolution Meet our e Booth 13250 Hall 13 www.upstreamtechnologymagazine.com 42017 EDITORIAL OFFICES UK: Upstream Technology, 7th Floor, 125 Wood Street London EC2V 7AN.
