TANKERS Jones Act trade. The vessel is divided into distinct modules for production that can be subcontracted to facilities experienced with that particular aspect of marine fabrication and outfit. Atlantic Marine Alabama is the primary fabrication and assembly shipyard.

L-3 Communications is responsible for the Integrated Diesel Electric Propulsion System and Integrated Bridge Systems, with Louisiana Machinery/Caterpillar Mak supplying the Main Diesel Generators. AHL TANKER PROJECT Key Project Milestones • Contract Signing – July 2, 2007 • Steel Deliveries Commenced – Nov. 19, 2007 • Start of Fabrication at R&R – Feb 11, 2008 • Start of Fabrication at Atlantic – Feb 18, 2008 • Keel Laying at Atlantic – April 2008 • Initial Module Loadout at R&R – July 2008 • Main Engines Arrive from Germany – Aug 2008 • Launch – March 2009 • Delivery – September 2009 • Follow Ship Deliveries – Apr. 2010 and Dec. 2010 MODULE BREAKDOWN The final module breakdown includes: main hull including bow structure, aft end structure, machinery power module, deckhouse, and main deck/cargo pipe rack. The philosophy behind each module boundary was to maximize pre-outfitting and commissioning of the systems and machinery prior to final assembly and to minimize the interface connections required at the interface shipyard facility. The final design is a vessel with an overall length of 188 meters, a beam of 32 meters and a design draft of 11 meters with a total cargo capacity of about 330,000 bbl in 12 tanks. The twin-screw diesel-electric machinery plant is configured with three medium speed diesel generator sets of 5,765 kW capacity each, any two of which will provide enough power to operate the vessel under normal conditions driving the 2 x 4,650 kW propulsion motors which give the vessel a range of 12,000 nautical miles at a service speed of 14.0 knots. The design utilizes primarily mild steel with high tensile steel used in higher stress locations such as the main deck, sheerstrake and upper strakes of longitudinal bulkheads. The aft deckhouse is configured for a complement of 30 crew that includes 22 single cabins for ship personnel and two additional four-person cabins for the riding crew. Other facilities include multiple recreation and mess spaces together with a gymnasium. An extensive model test program was completed to fine tune the resistance, sea keeping, and directional stability per- 32 MARINE LOG FEBRUARY 2008 www.marinelog.com http://www.bn-korea.com http://www.bn-korea.com http://www.marinelog.com
