Teekay adopts Wärtsilä technology for latest generation shuttle tankers

Wednesday, 10 Jan 2018

Four new shuttle tankers, to be built by Samsung Heavy Industries in South Korea for Teekay, will incorporate more than EUR 110 million of innovative Wärtsilä systems, making them the most sustainable vessels of this type so far.

The new shuttle tanker concept creates both economic and environmental benefits for owners

Central to their design is the ability to capture volatile organic compounds (VOCs), which evaporate during loading, and combine them with LNG as fuel for the Wärtsilä 34DF dual-fuel engines.
This, the companies claim, will reduce CO2 emissions by more than 40% compared with conventional shuttle tankers, cut NOx emissions by at least 80%, almost eliminate SOx emissions, and slash particulate pollution by 95%. Environmental gains will be matched by economic benefits – by using VOCs in the fuel mix, the ships will consume significantly less fuel.
The vessels will carry a number of other smart Wärtsilä features including a hybrid power distribution system, electric and automation plant including a low loss hybrid system and batteries, a LNGPac fuel storage and supply system, and the Wärtsilä VOC system for recovering and liquefying VOCs. The ships will also have Wärtsilä cargo and ballast pumps and inert gas generators, and their performance will be monitored by Eniram, a subsidiary.
