Icebreaking supply vessel













Arctech Helsinki Shipyard has been awarded a contract to build an icebreaking supply vessel for the Russia´s largest shipping company Sovcomflot. The new vessel will be built for the North East Sakhalin Offshore region oil and gas field where she will be used as a platform supply vessel for Sakhalin Energy Investment Company Ltd. (SEIC). The total value of the order is about EUR 100 million.

The vessel brings together the very latest innovations in arctic shipbuilding science and technology and is a further developed version of the two multifunctional icebreaking supply vessels Vitus Bering and Aleksey Chirikov delivered for Sovcomflot in 2012 and 2013. The new icebreaking supply vessel measures 100 m in length and 21 m in breadth. The six main diesel generator sets have the total power of about 21 000 kW and the propulsion power of 13 000 kW.

The vessel is designed for extreme environmental conditions in the Sakhalin area. The main duty of the vessel is to supply between land bases and the offshore drilling and production sites.

The vessel will be able to safely convey and transfer cargo on deck and bulk cargo underdeck in all seasons. The vessel will also be operating in thick drifting ice for ice management and icebreaking duties in temperatures as cold as minus 35 C°. The icebreaking capability of the vessel is extremely high, the vessel is able to proceed independently in 1.7 meter thick ice. The vessel will be outfitted for emergency evacuation, rescue and fire fighting operations, oil spill response and platform overboard working and helicopter operations. The vessel can also act as diving support vessel including a moon pool feature.
