The EUR110m order for four of these cutting edge vessels for Teekay were signed in December and this month. They will be built at the Samsung Heavy Industries (SHI) yard in South Korea powered by Wärtsilä 34DF dual fuel gas engines and will feature a very broad assortment of Wärtsilä’s latest technology innovations, all of which are central to the concept’s overall performance gains.
The concept offers a new level of economic and ecological performance, and is expected to reduce annual emissions of CO2 equivalents by more than 40%, compared to conventional shuttle tankers.Nitrogen Oxide (NOx) emissions will be cut by more than 80%, Sulphur Oxide (SOx) emissions will be almost entirely eliminated, and particulate emissions will be reduced by more than 95%.
In addition to operating on liquefied natural gas (LNG) as the primary fuel, the dual-fuel engines will also be able to run on a mixture of LNG and recovered Volatile Organic Compounds (VOC) – the gas evaporating from the oil cargo tanks during loading.
“Together with Teekay, we have developed a concept that takes the shuttle tanker sector into a new era, and which is further evidence of Wärtsilä’s ability to transform shipping by developing and utilising the very latest technologies. These ships will have tremendous operational flexibility with unmatched manoeuvring capability, and will achieve what all operators are striving for today, namely optimal economic and environmental performance,” said Wärtsilä Marine Solutions president Roger Holm.
“This new shuttle tanker design will set new standards for both fuel consumption and CO2 emissions,” added Terje Rusdal, project manager at Teekay.
Wärtsilä solutions are at the heart of this concept. Among the many innovative features is the Wärtsilä Hybrid system, on which the power distribution will be based. Other systems include Wärtsilä’s LNGPac fuel storage and supply system, and the Wärtsilä VOC system for recovering and liquefying the VOC with a storage and supply system.
