Four LNG tanks have been ordered for two Swedish-owned dual-fuel tankers
In conjunction with its marine fuel gas systems, LGM Engineering has contracted US-based Chart Industries to supply four LNG fuel tanks for two 22,000-dwt, dual-fuel oil products and chemical tankers under construction at China’s Wuhu Shipyard.
Ordered by Sweden’s Rederi AB Donsötank and designed by naval architectural firm FKAB Marine Design, the two tankers will each have a length overall of 167.7 m, beam of 26.5 m, draught of 9.2 m and capacity of 28,000 m3.
Propulsion power will be supplied by a Wärtsilä 10V31 DF main engine with the capability of burning LNG. Each vessel will be ice strengthened with a class notation of ice class 1A. The tankers will also have the capability to connect to shore power to lower emissions while in port and be ready to accommodate a 1,000-kW battery pack.
The 300 m³ capacity cryogenic tanks supplied by Chart will be fabricated with double stainless steel shells with vacuum and perlite insulation. Fitted on the main deck, the tanks will be designed and manufactured at Chart’s Changzhou, China facility and classified by DNV GL in accordance with associated regulations.
“With IMO 2020 regulations coming into force on 1 January, reducing the maximum sulphur content of marine fuel from the current 3.5% to 0.50%, Chart’s technology is integral to the increased number of LNG-powered ships on international waters and the bunkering infrastructure required to fuel them,” said Chart D&S Asia president Robert Chen.
Family-owned Rederi AB Donsötank will take delivery of the tankers in 2021.
