Wärtsilä to power four modern diesel-electric tugs for Australian owner 18 August 2012 Wärtsilä has been contracted to supply the power system for four new diesel-electric powered tugs being built for Svitzer Australia Pty Ltd. The vessels are being built at the ASL shipyard in Singapore and are scheduled to be in operation by early 2014. Each of the four 80 Ton Bollard Pull (TBP) harbor tugs will be fitted with two 9-cylinder and one 8-cylinder in-line Wärtsilä 20 engines. The use of the Wärtsilä 20 engines as diesel-electric generating sets is a new development in the tugs market. The engines will operate on Marine Gas Oil (MGO). The tugs will be equipped with batteries that allow power from the Wärtsilä generating sets to be stored for later use. Wärtsilä has earlier supplied integrated propulsion solutions for two Svitzer Tier III compliant ECOtug(s).
