GE Marine reports that the United States Navy’s future USS America (LHA 6) amphibious assault ship recently completed successful acceptance sea trials powered by two GE LM2500+ marine gas turbines. Acceptance sea trials were conducted in the Gulf of Mexico by Huntington Ingalls Industries, nearby its Pascagoula, Mississippi, shipyard. “The selection of the LM2500+ gas turbines offers propulsion commonality for this first-in-class ship with the U.S. Navy’s USS Makin Island LHD 8 amphibious assault ship. The LHD 8 was the first U.S. Navy ship to use this hybrid propulsion system configuration, as well as the first military application of the LM2500+ gas turbine,” said Brien Bolsinger, Vice President, Marine Operations, GE Marine, Evendale, Ohio. The LHA 6 ship's hybrid mechanical-electric propulsion system consists of two LM2500+ gas turbines and two, 5,000 horsepower auxiliary propulsion motors, allowing the ship to reach speeds in excess of 20 knots. The hybrid propulsion system enables the ship's propellers to be driven either by the gas turbines or by the electric motors, which are powered from the ship service electrical system. The hybrid propulsion system allows the ship to operate in a more fuel efficient mode throughout its speed range, America-class ships are 844 feet long,106 feet wide and displace 44,971 long tons, and can accommodate a crew of 1,204 (102 officers) and 1,687 troops

Tech & Design Solutions for Modern Workboats

“There is a cost implication for owners to comply with IMO Tier 3 and EPA Tier 4 requirements, which is causing an increase in engine prices of about 30 percent regarding Tier 4, which probably results in a five percent increase in total construction costs for U.S.-built tugs. In some countries such as Asia, with low labor costs, total costs can increase by 10 percent.” - Mike Fitzpatrick, President, Robert Allan Limited (Photo: Mike Zeft)

EPA Tier 4 regulations (for engines of 804 hp and higher) and propulsion advancements have many manufacturers and vessel designers changing course to adapt to new requirements and customer demands.   Jensen Maritime is designing a new 110-ft
