The integrated Wärtsilä solution, comprising the main propulsion equipment, the gas fuel supply system, and the cargo handling system, has been ordered for 3 new state-of-the-art 27,000 cbm LNG/Multigas Carriers for Evergas, the Denmark based transporter of petrochemical gases and natural gas liquids.
Wärtsilä explain that this order is an extension of the one placed in 2013 for a series of three similar vessels. The ships are being built by the Sinopacific Offshore & Engineering (SOE) shipyard in China, and feature an advanced design that offers very high efficiency and unparalleled flexibility.
For each vessel Wärtsilä will supply two Wärtsilä 50DF dual-fuel main engines, two Wärtsilä 20DF auxiliary gensets, the gearbox, and the controllable pitch propeller. Wärtsilä will also supply the Cargo Handling System with reliquefaction and an integrated LNG fuel supply system, enabling the vessels to utilize the LNG energy even further. This integration means that less energy and power is needed for cooling the cargo, thereby increasing both the efficiency and the environmental sustainability.
"Wärtsilä is extremely pleased to continue this valuable cooperation with Evergas and SOE. The concept that has been developed has proven to be extremely successful as evidenced by the fact that it is being continued for a further three vessels. Our integrated solution fully meets the design criteria for excellent fuel economy as well as superb redundancy," says Jaakko Eskola, Senior Executive Vice President & President, Ship Power, Wärtsilä Corporation.
"These vessels are the largest, most flexible and advanced multigas carriers yet to be built. By utilising Wärtsilä dual-fuel propulsion machinery capable of running on clean LNG, the ships will be Tier III compliant and have a minimal environmental footprint, which is important to our company. We appreciate Wärtsilä's valuable cooperation in this newbuild programme, and we are pleased that this extended order allows us to continue this excellent cooperation," says Martin Ackermann, CEO of Evergas.
The delivery of the 178 metre long vessels will take place during 2015. Wärtsilä's cooperation with the shipyard will continue until the vessels are launched.
