HHI Builds Twin-Engine VLCC

Stena Vision, a unique VLCC built by Korea's Hyundai Heavy Industries Co., Ltd. (HHI) in that it features twin-engines and twin-propellers, was recently christened at the Ulsan Shipyard. Concordia Maritime AB's new ultra-large 315,000-dwt VLCC was christened by Mrs. Karen Fidler, wife of the president of Sunoco Inc., the company that chartered the VLCC. Built for Concordia Maritime, a public tanker company of the Swedish-based Stena organization, the VLCC is a revolutionary type of crude oil carrier. The 1,102 ft. (336 m) long Stena V-Max design VLCC differs from other large tankers built in the world to date. In addition to double hulls, the VLCC has double, completely separate engine rooms, double rudders and double propellers. This twin-engine configuration gives the VLCC substantial advantages since one main engine can be shut down for maintenance while the vessel continues its voyage with the other. But these double functions represent an extra safety feature, and provide the VLCC with maneuverability touted as far superior to that of other conventional VLCCs. The new VLCC - with a service speed of 16.9 knots - also employs an exceptionally beamy, shallow-draft hull form. The vessel has a beam of 229.6 ft. (70 m), compared to the normal 190-197 ft. (58-60 m) one for VLCCs. These features make it possible for the VLCC to offer a 30 percent higher loading capacity on a limited draught than more conventional VLCCs. The second of the two-ship order is scheduled for delivery in June. When delivered, these two innovative VLCCs will be put on a charter to Sunoco Inc. in Philadelphia, one of the largest independent U.S. petroleum refiner-marketers. As per the charter agreement, the revolutionary VLCCs will service Sunoco Inc.'s two refineries located on the Delaware River near Philadelphia.
