Following similar orders placed in November 2012 and August 2013, Siem Offshore has again contracted Wärtsilä to supply the design and integrated solutions for four new platform supply vessels (PSVs). The ships will be built at the Remontowa Shipbuilding yard in Poland. The contract was signed in January 2014.
The four new vessels, like the two currently under construction, will utilise the Wärtsilä VS 4411 DF ship design and will have Wärtsilä dual-fuel propulsion allowing them to operate primarily on liquefied natural gas (LNG). With the various Wärtsilä systems having been integrated into a total solution, and with an optimised hull design, the vessels will feature lower fuel consumption, reduced fuel costs, and fewer exhaust emissions compared to vessels running on conventional marine fuel.
