Schottel’s drive system picked for the world’s first LNG hybrid tug April 13, 2021, by Adnan Bajic Singapore-based Sembcorp Marine has picked Schottel’s azuimuthal hybrid drive system for the world’s first liquefied natural gas (LNG) hybrid tug. With this first in a series of 12 vessels, Sembcorp Marine will build the world’s first hybrid LNG-fueled tug fleet that will replace its existing diesel-powered tugs, Schottel said in its statement. The vessel is designed by LMG Marin, a unit of Sembcorp Marine, and a naval architecture design house in Bergen, Norway. The tug’s future operation profile in the harbours of Singapore will demand highly variable power ranges.
