Wartsila reveals new ECA pump for LNG fueled engines
Wärtsilä Svanehøj informed that a new ECA Fuel Pump (EFP) has been developed in close cooperation with designers of liquefied natural gas fuel systems to support gas fueled engines that achieve greater efficiency.
The new Wärtsilä pump has no tank connections below liquid level, no electrical components inside the tank, and hardly any contribution to the generation of boil off gas. Having less heat and pressure build up in the fuel tank makes the new pump very safe, while in harsher operating conditions it also maintains the pressure, thereby ensuring a continuous gas flow to the LNG fuelled engine, the company said in a statement.
The Wärtsilä Svanehøj ECA Fuel Pump is designed to be compatible with Wärtsilä’s LNGPac fuel bunkering and supply system, and in accordance with regulations covering vessels operating in Emission Control Areas (ECAs). The pump can also be used with other types of fuel, such as ethane and methanol.
There are currently more than 5000 Wärtsilä Svanehøj deepwell gas pumps in operation around the globe. This latest version is designed for a service life of at least 25,000 operating hours or five year service intervals.
