NEWS Q4 2012 also saw Arctech Helsinki ink an order,
Each cat in the Wind Express 27 series will carry approximately 10tonnes’ worth of wind turbine spares and related equipment
Express 27 class, will comprise 26.5m loa, 12-passenger cats, each with the capacity to carry 10tonnes’ worth of equipment and turbine spares, and they will operate at service speeds of approximately 27.5knots. Te vessels will be constructed at Austal’s facilities in the Philippines, which the group acquired in November 2011, specifi- cally to reduce costs and thereby to gain a competitive advantage in supplying larger transfer vessels to European offshore wind farm service suppliers. Each cat in the Wind Express 27 series will be
powered by four Caterpillar C18 diesel engines, steering Rolls-Royce Kamewa waterjets, and will feature Z-bow hullforms. Austal will also install a ride control system, made up of forward T-foils and transom interceptors, in a bid to reduce excessive rolling. Te vessels will be classed by DNV, and construction of all three is planned to take place between March and December 2013.
Arctic Vitus Bering breaks the ice
Arctech Helsinki has delivered its 99.9m x 21m x 7.6m ice-breaking rescue vessel Vitus Bering, previously NB506, to Russian operator Sovcomflot. Te vessel, which was originally ordered in December 2010 (see p.26, Offshore Marine Technology Q3 2012), features the ability to handle ice thicknesses of up to 1.7m, and in temperatures plummeting to -35˚C, and has commenced operations in the Arktunun-Dagi oil and gas field, in the Sakhalin region, off Russian’s eastern coast. Vitus Bering is powered by four Wärtsilä engines, two
rated at 3,000kW and the other pair at 6,000kW, result- ing in a service speed of 15knots for this 3,950dwt vessel. Te ship can accommodate up to 22 members of crew and as many as 195 rescued persons. Arctech Helsinki is now working to complete a sister vessel, NB507, which will join Vitus Bering at the Arktunun-Dagi site upon delivery. Speaking at Vitus Bering’s handover, in December 2012, Jonas Packalén, Arctech Helsinki Shipyard project manager, said: “Te building of NB-506 has been a challenging
project...it is a great pleasure to deliver this technically demanding vessel to the client four months ahead of schedule.”

valued at approximately €100 million (US$134 million) to build and deliver a 120m x 27.5m icebreaker to the Russian Ministry of Transport. Te vessel will be deployed in the Black Sea on a year-round basis, and in the Arctic during the Summer season, and will be designed to operate in temperatures as low as -40˚C, with a maximum icebreaking capacity of 1.5m. Arctech Helsinki will build the vessel in cooperation with Russia’s Yantar Shipyard, with Vyborg Shipyard providing the basic design, major components and half of the vessel hull blocks. Scheduled for handover in August 2015, the vessel will be equipped with four main diesel generator sets, rated at 27MW combined.
Contract Ulstein wins order for
multifunctional ship Ulstein has entered into a contract to deliver a 130m x 25m multifunctional offshore vessel to Island Offshore. Based on Ulstein’s SX121 design, the forthcoming vessel will be customised with well intervention, repair and maintenance and offshore construction tasks in mind. Te vessel will be equipped to Dynamic Position-
ing 3 (DP3) capabilities, and be capable of performing subsea operations at depths down to 3,000m. A vertical lay system (VLS) will facilitate the laying of cables and flexible pipes upon the seabed, and it is likely that a rotating carousel will be installed below deck, this item featuring the capacity to load 2,500tonnes. Ulstein is also planning the installation of an active
heave compensated crane, with a 250tonne capacity at 14m outreach, as well as a below-deck winch. Te vessel will carry two ROVs, for deep-sea operations, which crew will be able to launch from the starboard side or from a moon pool. In terms of propulsive arrangement, the vessel is intended to incorporate diesel-electric engines, three azimuth main thrusters and six large generator sets. In total, the ship will be able to accommodate up
to 130 persons, and will meet the safety requirements for vessels operating off the Norwegian Coastal Shelf. Delivery is scheduled for May 2014. OMT
