The Energy Storage system will be based on Lithium-Titanium-Oxide (LTO) batteries, which can handle higher amounts of deep cycles than normal Lithium-Ion based systems. The ESS will significantly reduce the fuel consumption and/or the necessary size of the port's electric shore connection during crane operations while providing fuel savings at sea by reducing Engine Load fluctuations in rough seas. For each vessel, Wärtsilä will supply the gearbox, the CP propeller, the bow and stern thrusters, air shaft seals, as well as the sterntube and bearings. Dr Martin Harren, Owner and CEO, SAL Heavy Lift, said: "These ships represent the next generation in heavy lift shipping. In addition to their technical capabilities, they will feature outstanding environmental performance and help guide shipping towards a greener future.
