The American Bureau of Shipping (ABS) has granted an approval in principle to Japan’s Kawasaki Heavy Industries Ltd. (KHI) for its LPG as Fuel system design. The design is for a dual-fuel vessel propulsion engine capable of using both marine diesel oil and LPG as fuel. KHI maintains the system simultaneously reduces fuel consumption and enables the power plant to meet nitrogen oxide Tier 3 emissions regulations.

“Using LPG as a fuel can lower emissions to air compared to conventional fuels, both in terms of greenhouse gas emissions and other pollutants,” said Patrick Ryan, ABS senior vice president of global engineering and technology. “We are proud to work with innovative partners such as KHI, supporting the delivery of the next generation of cleaner vessels.”

KHI’s design is for an electronically controlled, LPG-injection marine diesel engine, or ME-LGIP, the first order placed for an engine of this type in Japan. “LNG as fuel is attracting widespread attention as an environmentally friendly option, but LPG as fuel has advantages over LNG, including potentially reduced initial investment and simpler handling onboard,” said Hideaki Naoi, KHI general manager. “As a result, we believe LPG as fuel will prove increasingly attractive to the market in the future.”

ABS is a leading global provider of classification and technical advisory services to the marine and offshore industries.
