Keppel Offshore & Marine’s subsidiary Keppel Shipyard has secured a contract from Totem Ocean Trailer Express for the conversion of its ro / ro vessel to dual fuel liquefied natural gas (LNG) propulsion.
The conversion of Midnight Sun is claimed to be the world’s first major conversion of a large ro / ro vessel to LNG.
Totem Ocean president John Parrott said: "Totem Ocean is excited to partner with Keppel for the conversion of the Midnight Sun, enabling her to operate on natural gas.
"The removal and replacement of the four engines, adding 2,200m³ of LNG capacity along with the addition of 47km of new cabling is a complex undertaking, and we are confident that Keppel will provide safe, timely, high-quality work to ensure the best outcome for Totem Ocean and our customers."
With the conversion, the vessel will be able to reduce the emissions of particulate matter by 91%, SOx by 90%, and carbon dioxide by 35%.
Midnight Sun’s sister ship, the North Star, is expected to be converted in the 2016 / 2017 time frame, the company has stated.
Meanwhile, Puget Sound Energy, in collaboration with Totem Ocean and the Port of Tacoma, is planning to construct an LNG liquefaction terminal at the port.
The new facility, which is scheduled to be complete by the end of 2018, will serve Totem Ocean, residents of Puget Sound and the broader transportation industry in the Pacific Northwest.
In July, Keppel Shipyard received a $684m contract from Golar LNG for the conversion of a Moss type LNG carrier, the Gandria, into a Golar floating liquefaction (GoFLNG) facility.
