Marine Log (ML): The world's first LNG-hybrid tug is being built in Singapore. How long before we start seeing hybrid tugs here in the U.S.? Dave Lee (DL): The idea of hybrid tugs has been around for some time, with Foss Maritime adopting batteries over a decade ago. Then ABB saw a pause in the push for advanced vessels until 2019. It is now apparent that the next generation of newbuild advanced propulsion tugs in the U.S. has officially started. In 2019, tugs were built with small electric motors to still assist the main engines for part of the propulsion, but the power for the electric motors still come from diesel generators, so they are diesel electric assisted in the design sense. This is the most common first step that we have seen around the world as owners are cautious about how much new technology they want to adopt. The downside to a cautious approach is that the owners are pretty much tied to the main diesel engines for the life of the tug. The upgrade to electric is still possible, but it is not an easy upgrade. This is compared to operators who built their tug with an electric motor as the main propulsion. the market in the next 30 years.
