NYK to further reduce GHG emissions with new PCTCs

Japan’s NYK Line has placed an order for four pure car and truck carriers (PCTC) of 72,800gt fuelled by liquefied natural gas (LNG) at Jinling Shipyard in China.

The contract is part of NYK’s plan to replace current vessels with around 40 newly built LNG-fuelled PCTCs over the next decade to achieve NYK’s environment management target. The target is to reduce carbon dioxide emissions per tonne-kilometre of transport by 50% by 2050.

The vessels now ordered will be 199.9m long, 38m wide and carry 7,000 car equivalent units of vehicles. The four vessels are due to be delivered from 2022 to 2023 and will have a new main engine of WinGD’s X-DF2.0 iCER type. This engine consumes less fuel and reduces greenhouse gases by cutting methane emissions from exhaust fumes by about 50%. The vessels will also be equipped with battery hybrid technology, which will improve fuel efficiency by compensating main engine and electrical generator load fluctuations through the support of batteries.

The use of LNG fuel, together with supporting technologies and other developments such as hull modification, will contribute to a reduction of sulphur oxide emissions by 99% compared to ships fuelled by heavy fuel oil, NYK said. Nitrogen oxide emissions will be cut by 96% and carbon dioxide emissions by about 40% or more per unit of transport. NYK aims to further advance to zero-emission vessels utilising low-emission marine fuels, such as hydrogen and ammonia, from around 2035.
