The PSVs are based on Wärtsilä Ship Design?s VS 485 PSV MKIII design; designed to offer a high energy yet environmentally ef Þ cient vessel courtesy of an optimized hull design for greater efÞ ciency, with corresponding reduced emission to air. The AHTS vessels are to be con- structed according to the Wärtsilä Ship Design VS 4612 AHTS design. The primary function of AHTS vessels is to set anchors for drilling rigs, and tow mobile drilling rigs from one location to another. Since the sea and weather conditions in which these ships work is often extremely challenging, a design that offers reli- ability and high levels of efÞ ciency and performance is called for. Wärtsilä Wins Subsea 7 DSV Design Deal Wärtsilä signed a contract for the design of a new diving support vessel (DSV) to be built for Subsea 7. The new VS 4725 DSV design was created by Wärtsilä Ship Design speci Þ cally for this vessel, which will be built at the Hyundai Heavy Industries (HHI) shipyard in Korea. The contract was signed with HHI in December, and the vessel is scheduled for delivery in 2015.The vessel is intended for North Sea diving operations on a year round ba-sis. In customizing the design, close co-operation between Subsea 7, HHI, Drass Energy, the diving equipment supplier and Wärtsilä was employed. The result: a technologically advanced vessel design that should offer high safety and good working conditions to all personnel onboard, as well as safe and efÞ cient operations in often challenging sea and weather conditions. The DSV will be equipped with the latest integrated diving equipment, with a three-split engine and propulsion conÞ guration for redundancy. Under this conÞ guration, the systems relating to the generator sets, propulsion ma- chinery, thrusters, electrical controls and all related auxiliary equipment, are divided into three sections. This is also designed to ensure a high ERN (Environmental Regularity Number) score, while limiting the failure risk. In a worst case failure scenario, most of the generator sets and thrusters will remain in operation. ?The development of the Wärtsilä VS 4725 DSV, the development of the dive system by Drass, and the overall design and building by HHI is the result of good cooperation between all the parties involved,? said Stuart Smith, Vice President for Technology and Asset Development, Subsea 7.

BP ......approx. 145t PSV LaunchedThe largest ship ever built by The Craig Group, an S class Platform Supply Vessel (PSV), launched at Balenciaga Shipyard in Northern Spain. The Craig Group has committed $81m to the construction of the vessel, The Grampian Sovereign, and its sister ship, The Grampian Sceptre. Man- aged by The Craig Group division North Star Shipping, the two IMT-982 designed vessels will also create 50 new jobs for the Aberdeen-based company. Going on long term charter in 2013 in the North Sea, the vessel represents a contin-ued drive by the group to operate the larg- est and most modern British wholly owned ß eet engaged in the UK offshore industry, supporting 50 installations in the North Sea. The vessels are 83m long with an 18m beam and have diesel electric propulsion systems offering a greater fuel economy and efÞ ciency. They have been speci Þ cally designed to meet the requirements of oper- ators in the North Sea. North Star manag-ing director, Callum Bruce, said: ?We are constantly looking at ways of modernizing our ß eet through new builds using the most up to date vessel technology and designs as we aim to meet our customers? needs in terms of safety, quality and ef Þ ciency.? This investment brings the total new-build programme by Craig Group since 2003 to over $375m, representing 22 new vessels built. ESG Launches Harvey Deep-Sea Eastern Shipbuilding Group launched Harvey Deep-Sea, the fourth of its Tiger Shark Class Offshore Support Vessels being constructed for Harvey Gulf Inter- national Marine, LLC of New Orleans, LA. Harvey Deep-Sea was launched on December 12, 2012, after completing all regulatory hull exams. Harvey Deep-Sea is Eastern?s second Construction Vessel (LCV) for Harvey Gulf, and the yard has built 10 vessels for Harvey Gulf International since 2002.ABS class includes the ABS DPS-2 no- tation and FIFI 2. It is AC Diesel-Electric powered with twin Schottel Z-drives and it measures 302 x 64 x 24.5 ft.. This Multi- Purpose Construction Vessel (LCV), the Harvey Deep-Sea, will be equipped with an active heave-compensated, National Oilwell Varco 165-ton knuckle boom crane capable of lifting/setting 100 tons at depths up to 10,000 ft. The Harvey Deep-Sea is scheduled for Þ nal out Þ tting and delivery in the summer of 2013. MR #1 (42-50).indd 49MR #1 (42-50).indd 491/3/2013 11:37:59 AM1/3/2013 11:37:59 AM
