October 2012www.marinelink.com 27The marine geophysical com- pany Polarcus Limited received its eighth 3D seismic vessel on 21 June 2012 when PolarcusAdira was delivered at Ulstein Verft in Norway. The vessel is the second of two 12-14 streamer Arctic 3D seismic vessels built at the yard, and is the eighth vessel in the Polarcus fleet of the Ulstein SX134design, characterized by the sleek UlsteinX-bow hull design the shipbuilder has be- come known for. The sistership Polarcus Amani was delivered by the yard at the end of March. Earlier vessels were built under license by Drydocks World Dubai LLC.. They include Polarcus Nadia (2009), and Polarcus Naila (2010), 12streamer vessels of type SX124, Polar- cus Asima (2010) and Polarcus Alima (2011), 12 streamer vessels of type SX134, Polarcus Samur (2011) and theRussian flag vessel Vyacheslav Tikhonov (2011), 8 streamer vessels of type SX133. The other vessels carry Bahamas flag. All vessels are designed by Ulstein Design and Solutions AS. Following a short shakedown Polarcus Adira will com- mence operations on charter for TGS- NOPEC Geophysical Company ASA (TGS). Polarcus Limited, registered on the Oslo Stock Exchange, operates a fleet ofhigh performance 3D/4D seismic vessels. Polarcus offers contract seismic surveys and multi-client projects worldwide and employs over 500 professionals. The company's principal office is in Dubai, United Arab Emirates. Main vessel data The hull of Polarcus Adira and Polar- cus Amani were built at Kerch Shipyard Zaliv in Ukraine. As is the custom for the ships built by Ulstein Verft shipyard in Ulsteinvik. This was the seventh hull built at the yard. The vessels are equipped with streamer winches, towing points and gun winches. The X-bow hull line design, combined with a redundant diesel-electric propul-sion system, ensures good performancewith regard to speed and fuel consump- tion. The overall length of Polarcus Adira, yard number 293, is 92m and thebreadth is 21m, which is identical tothose of sister vessel Polarcus Amani. Depth to main deck is 9.0 m, design draftis 6.5m and maximum draught 7.5 m.The deadweight at maximum draught is4,472dwt. Gross tonnage is 7709GT andnet tonnage 2313NT. The hydrodynamic efficiency of the X- BOW, result in good sea-keeping abili- ties, it also provides a safe and comfortable workplace for the crew both during transit and seismic surveys, as it eliminates slamming. The soft entry in waves also reduces spray and eliminates icing. The vessel is equipped with a he- lideck (D-value 22.2 m, 12t, UK-CAA CAP-437 suitable for Sikorsky S-61N / S-92) for added safety and to ensure anefficient crew change, and is built ac- cording to IMO code of safety for Spe-cial Purpose Ships (SPS), enabling it tooperate worldwide. The vessel has two workboats, by Westplast, and a Norsafe MOB boat onboard and six life rafts eachfor 35 persons with dedicated davit. Machinery The vessel has diesel-electric propul- sion. The main propulsion system com- prises two Wärtsilä 9L26 main diesel generators, each 2920ekW at 1000rpm,plus four Wärtsilä 9L20 1710ekW diesel SEA READYSEA TOUGHSEE SILVERSHIPS.COM 251-973-0000 ? silverships.com DESIGNERS AND BUILDERS OF ALUMINUM BOATS VISIT US AT THE INTERNATIONAL WORKBOAT SHOW BOOTH # 126 MR#10 (26-33):MR Template 10/2/2012 11:13 AM Page 27
