Japanese shipping company NYK has concluded a shipbuilding contract with China Merchants Jinling Shipyard (Nanjing) Co. Ltd. for four LNG-fuelled pure car and truck carriers (PCTC).
The vessels will be the first to feature WinGD’s X-DF2.0 iCER main engine, which, says NYK, consumes less gas and reduces GHG by cutting methane emissions from exhaust gas by approximately 50%.
The vessels will also be equipped with battery hybrid technology, which will improve fuel efficiency by mitigating main engine and electrical generator load fluctuations through the support of batteries.
NYK says the use of LNG fuel, together with these new technologies and other developments such as hull modification, will contribute to a reduction of sulphur oxide (SOx) emissions by 99% compared to ships fuelled by heavy fuel oil. Likewise, nitrogen oxide (NOx) emissions will be cut by 96%, and CO2 emissions by approximately 40% or more (per unit of transportation).
Concluding this shipbuilding contract for these four vessels is in line with NYK’s plan to replace current vessels with around 40 newly built LNG-fuelled PCTCs over the next decade to achieve the company’s environment management target, which is to reduce CO2 emissions per ton-kilometre of transport by 50% by 2050. NYK says it aims to further advance to zero-emission vessels utilising low-emission marine fuels such as hydrogen and ammonia from around the mid-2030s.
These four vessels will be delivered from 2022 to 2023 and are planned to be assigned to transport vehicles mainly to and from Europe and/or to the Middle East.
