Wärtsilä will provide its Volatile Organic Compounds (VOC) Recovery System, together with an LNG Fuel Gas Supply System, for two new 124,000 DWT shuttle tankers.
The ships, which will operate in the North Sea oil fields, have been ordered by Knutsen NYK Offshore Tankers (KNOT), an independent owner and operator of shuttle tankers, and will be built at the Daewoo Shipbuilding & Marine yard in Korea.
The Wärtsilä solutions will be delivered to the yard commencing in November of this year.
With this technology, the liquefied VOC is mixed with LNG and used as fuel for the main and auxiliary engines. By using LNG as the primary fuel and supplementing this with the energy recovered from the VOC, these vessels will be able to lower their emissions of CO2 equivalents by 30 to 35%, a minimum of 30,000 tons per year, compared to conventional oil-fueled shuttle tankers.
These savings are roughly the equivalent of the total emissions from approximately 20,000 cars.
