The technology group Wärtsilä’s emissions abatement technology is again recognised with a new order. The company 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 have been ordered by Knutsen NYK Offshore Tankers (KNOT), a leading independent owner and operator of shuttle tankers, and will be built at the Daewoo Shipbuilding & Marine yard in Korea. The order with Wärtsilä was placed in April.
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 percent, a minimum of 30,000 tons per year, compared to conventional oil-fuelled shuttle tankers. These savings are roughly the equivalent of the total emissions from approximately 20,000 cars.
Our industry is rapidly changing towards greater environmental awareness and improved operational efficiency. These two new ships will reflect this change, thanks largely to Wärtsilä’s advanced technology. They will truly represent the new generation of shuttle tankers, with vastly reduced emissions and lower fuel costs.Jarle Østenstad, Newbuilding Director, Knutsen OAS Group
