Battery power provides boost for gas-fuelled ships

摘要

Four years ago, platform supply vessel (PSV) Harvey Energy became the first US ship fuelled by LNG when it went on charter to Shell in the Gulf of Mexico. Harvey Energy will soon make history once again as the first US-flag, dual-fuel, battery hybrid-powered PSV, after a retrofit at New Orleans-based Harvey Gulf International Marine's shipyard. "The vessel can already outperform any PSV in the [US Gulf of Mexico] today in terms of speed, emissions, cost for fuel and fuel burn," says Harvey Gulf International Marine chief executive Shane Guidry. "We want to continue to bring lower emissions and lower fuel cost savings to our customers."
