March 1, 2023, MTS Curiosity had a successful trial run and a month before that MTS Courage. The type C tankers measure 93 x 10.5 meters and the diesel-electric propulsion is made possible by 2 Veth compact L-drives and 3 Scania generator sets D13. They each have 4 tanks with a total volume of 1220 cubic meters. The tanks, pipes and pumps are rubberized, making them suitable for transporting hydrochloric acid. We thank HGK shipping for the assignments and wish ship and crew a safe journey.
