PCTCs to surpass IMO 2030 targets with WinGD energy setup

Four pure car and truck carriers (PCTCs) ordered by Japan’s NYK Line at China Merchants JinLing Shipyard (Nanjing) are to have WinGD hybrid energy systems enabling them to exceed IMO 2030 targets on cutting greenhouse gas emissions.

The integrated systems will comprise WinGD’s 7X62DF-2.1 two-stroke engines running on LNG, shaft generators, DC links and batteries. The setup is expected to cut CO2 emissions by about 40% compared with similar vessels operating on heavy fuel oil.

WinGD’s knowledge of the engine’s operation has enabled it to optimise the integrated system, making the most of spinning reserves, peak shaving, and energy flows. The engine can therefore run constantly at optimal load while avoiding inefficient use of generators. The company’s new Hybrid Control System will be used to integrate and manage the setup.

Keita Fukunaga, deputy manager of the Ship Design Team in NYK Line’s Technical Group, commented: "Battery hybrid technology improves fuel efficiency and emissions by mitigating main engine and electrical generator load fluctuations. This project is an important step in our plan to replace current vessels to newly built LNG-fuelled PCTCs, reducing the fleet’s carbon intensity by 50% by 2050."

WinGD’s Stefan Goranov, Program Portfolio manager, Digital & Hybrid, observed that an appropriately controlled hybrid energy system is emerging as one of the most cost-effective ways for deep-sea vessels to meet future environmental targets. This involves combining the high efficiency of low-speed, two-stroke engines with optimally sized electric drives, machines, and energy storage units, he said.
