New Device for More Efficient LNG Power
In an effort to improve the efficiency of liquefied natural gas (LNG) as a fuel, U.S. and U.K. marine engineering company Houlder Ltd. (Houlder) says it has developed a device to manage boil-off gas.
The stand-alone unit, designed for bunker vessels and client ships, recondenses vapour created by warming tanks or during fuel transfer, reducing the footprint and power requirements of host vessels.
It also promises to provide savings for vessels with slow-speed, low-pressure engines with non-pressurised tanks, which do not allow for management of boil-off gas through changes in tank pressure.
"We're very excited to have announced our concept this week," said Ian Meaden, the company's lead on LNG Projects.
"We've already engaged with industry and will work more closely with stakeholders throughout 2014 to bring the system to market."
Johan Sperling, vice president of Jensen Naval Architects and Marine Engineers, recently said that, while LNG is cheaper and less polluting than diesel, it is not as power-efficient.
