Switzerland-based Winterthur Gas & Diesel (WinGD) has won a contract to integrate hybrid energy systems on four LNG-powered car carriers for Japan’s shipping giant NYK.
The four LNG-powered pure car and truck carriers (PCTC) will feature WinGD’s 7X62DF-2.1 two-stroke engines coupled with shaft generators, DC-links and battery systems.
“Based on its in-depth knowledge of the main engine’s performance WinGD has optimized spinning reserves, peak shaving, and energy flow to run the main engine constantly at its sweet spot while avoiding inefficient generator loads,” the firm said in a statement.
In addition, WinGD will be responsible for the system integration and system-level energy management, through WinGD’s new hybrid control system.
Combined with other ship design enhancements, the LNG-battery configuration would cut overall CO2 equivalent emissions by around 40% compared to conventionally powered vessels operating on heavy fuel oil, taking them beyond IMO’s 2030 target for greenhouse gas (GHG) emissions, WinGD said.
NYK has ordered the four LNG-powered PCTCs from China Merchants Jinling Shipyard earlier this year.
The Chinese yard will deliver the ships with a capacity to carry about 7,000 units in 2022 and 2023.
NYK said it would use the 200 meters long PCTCs to transport vehicles mainly to/from Europe and/or to the Middle East.
