Jensen Maritime Consultants, Inc., a Crowley company, has designed two new barges for Global Marine Transportation, Inc. Both 10,000-barrel tank barges are scheduled to be constructed and delivered in 2010. Designed for lightering services, the barges are being built by Trinity Marine Products, Inc., and will be chartered to Maxum Petroleum, Inc.
The tank barges are designed with corrugated cargo tank bulkheads to ease tank stripping and cleaning. All cargo tanks are completely smooth-sided except for the deck stiffeners above. The structure and deck arrangements were fully modeled to allow visualizations of the structural parts and the working deck before any steel is cut.
The first barge, due to be delivered in June 2010, will carry diesel oil and jet fuel in, and around the ports of Los Angeles and Long Beach, Calif. It has a day room and sleeping quarters in a forward deckhouse, for accommodations during times of remote anchorage. While the pump engines and generator are housed in a pump room aft, there is also a midship control booth for centralized control and observation of bunkering operations.
The second barge, to be delivered in July, will be home-ported in Seattle, Wash., and will carry diesel and lube oils in segregated tanks. Both barges are double-hulled completely to OPA-90 standards and will be ABS-classed as well as USCG-inspected.
