Teekay Offshore Partners will exercise its option with Samsung Heavy Industries for the construction of two, Suezmax-sized, DP2 shuttle tankers.
The newbuilds, which will cost $US265 million, will be based on the new Shuttle Spirit design that incorporates LNG propulsion technology, increased fuel efficiency and reduced emissions.
Upon delivery in 2020, these vessels will join Teekay Offshore's contract of affreightment (CoA) fleet in the North Sea.
"What makes me particularly proud is that these newbuildings, as well as the two shuttle tankers ordered in July 2017 to service Statoil's needs in the North Sea, will set new standards for both fuel consumption and CO2 emissions," said President and CEO of Teekay Offshore Group Ingvild Sæther.
