Next-gen Teekay shuttle tankers to add optimisation technologies

A new series of four ‘smart’ shuttle tanker concept vessels being developed by Teekay are set to be fitted with Vessel Performance Management software from Wärtsilä subsidiary Eniram, alongside a range of other energy and emissions management systems and machinery, as part of a €110 million deal for Wärtsilä.

The four ‘next generation’ vessels will be built by Samsung Heavy Industries (SHI) in South Korea after orders were placed in December 2017 and January 2018.

The Eniram system will provide a data collection platform which will be used to drive optimisation of the vessel’s operations, while also providing the owners with analytics and reporting.

In conjunction with a range of other efficient machinery and energy storage systems being installed on the ships it is estimated that Teekay will be able to reduce annual emissions of CO2 equivalents by more than 40 per cent, compared to conventional shuttle tankers.

The vessels will operate on Liquefied Natural Gas (LNG) as the primary fuel, with dual-fuel engines capable of running on a mixture of LNG and recovered Volatile Organic Compounds (VOC) – the gas evaporating from the oil cargo tanks during loading.

By utilising the recovered VOC as fuel rather than venting it to the atmosphere, harmful emissions will be eliminated and the ships’ bunker needs will be significantly reduced, while Nitrogen Oxide (NOx) emissions from the engines’ exhaust will be reduced by more than 80 per cent and Sulphur Oxide (SOx) emissions will be almost entirely eliminated.

In total, the new concept ships aim to reduce particulate emissions by more than 95 per cent, creating significant environmental benefits while also being economically advantageous for Teekay through the reduction of fuel costs.

“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,” said Roger Holm, president, Wärtsilä Marine Solutions.

“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.”
