Hapag-Lloyd has commissioned the South Korean shipyard Daewoo Shipbuilding & Marine Engineering to build six ships, each with a capacity of over 23,500 TEU. The container liner shipping company had already placed an order for six ships of the same size at the end of 2020. Thus, the fleet will be expanded by a dozen 23,500+ TEU ships in total. The large container ships will be outfitted with a high-pressure dual-fuel engine that will be extremely fuel-efficient. Their engine will operate on LNG, but the vessels will also have sufficient tank capacity to operate on conventional fuel as an alternative. Hapag-Lloyd is focusing on liquefied natural gas as a medium-term solution, as it reduces CO2 emissions by around 15% to 25% and emissions of sulphur dioxide and particulate matter by more than 90%. Fossil LNG is currently the most promising fuel on the path towards zero emissions. The medium-term goal is to have ships that operate in a climate-neutral way using synthetic natural gas.
