Wärtsilä to Provide Systems for 'Most Environmentally Sustainable LNG Carriers Ever Built'

Evergas will be able to use the ship for LPG and Ethane as well as LNG

Wärtsilä Corporation (Wärtsilä) says it will supply integrated systems for a series of dual-fuel liquefied natural gas (LNG) carriers that will make them "the most modern and environmentally sustainable LNG carriers ever built."

Danish petrochemical gases and natural gas transporter Evergas has ordered the ships, which will be able to carry and reliquefy Ethane and liquefied petroleum gas (LPG) as well as LNG, from the Sinopacific Offshore & Engineering (SOE) shipyard in China.

The Wärtsilä equipment for the ships will include dual-fuel engines, propulsion equipment, cargo handling packages, and Wärtsilä Energopac rudders, which streamline water flow to reduce resistance and increase propulsion power.

"The customer's essential requirements for these vessels are to achieve the operational and fuel efficiencies needed to optimize their operating costs, while at the same time complying with the upcoming Tier III environmental regulations," said Aaron Bresnahan, Vice President Sales, Wärtsilä Ship Power.

"The advanced technology solution to be provided by Wärtsilä, whereby the cargo handling system, the gas supply system, and the propulsion machinery are fully integrated with each other, will make the vessels the most modern and environmentally sustainable LNG carriers ever built."

The ships will run primarily on LNG to comply with anticipated environmental regulations but will also be capable of operating on various conventional fuels, allowing for flexibility and redundancy.

Wärtsilä said the fact that it is supplying various components for the ships as integrated systems means it can achieve better results, for example by using the LNG supply system to provide cooling in the cargo handling system in an efficient, environmentally friendly manner.

Wärtsilä, a major supplier of dual-fuel technology for LNG carriers, recently signed an agreement to maintain the largest ever liquefied natural gas (LNG)-powered passenger ferry, Viking Grace.
