WÃ¤rtsilÃ¤, the marine industry’s leading solutions and services provider, has been contracted to supply the power system for four new diesel-electric powered tugs being built for Svitzer Australia Pty Ltd. The contract again represents confirmation of WÃ¤rtsilÃ¤’s ability to meet the demands for operational economy and environmental sustainability set for modern vessels in different shipping segments. The contract was signed in Q2/2012. 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) harbour tugs will be fitted with two 9-cylinder and one 8-cylinder in-line WÃ¤rtsilÃ¤ 20 engines. The use of the WÃ¤rtsilÃ¤ 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 WÃ¤rtsilÃ¤ generating sets to be stored for later use.
“Modern tugs need to feature both fuel efficiency and environmental sustainability, as well as lifecycle reliability. This contract represents further evidence of WÃ¤rtsilÃ¤’s strength in meeting these demands, and further emphasises our ability to offer sophisticated diesel-electric machinery solutions for this particular sector of the marine industry,” says Aaron Bresnahan, Vice President, WÃ¤rtsilÃ¤ Ship Power Specials.
“By selecting WÃ¤rtsilÃ¤ 20 engines for the diesel-electric generating sets, the owner will benefit from their robustness and reliability, which has been proven by the fact that more than 4000 of the engines have been delivered since this model was introduced to the market in the early 1990s. The WÃ¤rtsilÃ¤ 20 offers low exhaust gas emissions, low operating costs, fuel economy across the entire engine operation range, and high redundancy,” says Bresnahan.
WÃ¤rtsilÃ¤ has earlier supplied integrated propulsion solutions for two Svitzer Tier III compliant ECOtug(s).
