Major LNG ship engine order for Wartsila
Wartsila is to supply twenty-four Wartsila 50DF dual-fuel engines to Samsung Heavy Industries Co Ltd of Korea. These engines will power a series of six 155,000 m3 dual-fuel-electric LNG carriers.
Four of these ships are for A.P. Moller of Denmark, two are for Kawasaki Kisen Kaisha Ltd ("K" Line) of Japan.
Delivery of the first ship of the six ships is scheduled for early 2008.
Each ship will be equipped with three twelve-cylinder and one six-cylinder Wartsila 50DF dual-fuel engines, delivering a total power of 39.9 megawatts. Delivery of the engines from Wartsila's engine factory in Trieste, Italy, will commence in January 2007.
"The intensive cooperation between Samsung and Wartsila since 2001 to find innovative solutions for LNG carrier propulsion is finally bearing fruit in the form of concrete orders, and more orders can be expected," said Mr. C.Y. Kim, Vice President, Design Engineering at Samsung Heavy Industries.
"Dual-fuel-electric machinery offers significant efficiency and environmental benefits in comparison to steam turbine machinery. This is the main reason why 'K' Line has selected dual-fuel-electric machinery," said Mr. Joichi Sasaki, Manager, Gas Carrier Technical Team at "K" Line.
"The fact that five different ship owners and three different shipyards have now committed themselves to dual-fuel-electric LNG carriers is a strong encouragement to this new concept where obvious financial benefits, especially for ship and cargo owners, are recognized," said Mikael Makinen, EVP and head of Wartsila ship power business, adding that "we will see many more LNG carrier newbuildings to be ordered with this solution in the years to come."
The dual-fuel-electric machinery concept for LNG carriers combines multiple dual-fuel generating sets with electric propulsion and offers significant improvements compared to the traditional steam turbine installation in terms of operating economy, exhaust gas emissions and redundancy.
At the same time, it keeps aspects like safety, reliability and maintainability at an appropriate level. Crewing of dual-fuel-electric LNG carriers is not problematic either.
Fifty-two Wartsila 50DF dual-fuel engines have so far been ordered for application in thirteen dual-fuel-electric LNG carriers.Ê Wartsila dual-fuel engines have also been selected for FPSOs, dual-fuel-electric offshore supply vessels, as well as a large number of onshore power plants.
