A new multi-purpose fishing vessel paired with Yanmar 6AYEM-GT series engines is set to create waves in Western Australia’s marine
Shoreline Marine Fabrication based in Henderson built the 86-foot Global Marine Design aluminium vessel. It was launched for sea
trials and systems testing off Fremantle in December, 2018 and it turned in an impressive performance.
Named the Ada Clara, the 26.2m long, 50 tonne fishing craft can carry a 14-plus tonne fuel and catch load and will take its place as
the flagship for the Western Wild Fisheries company.
Ada Clara has two 737kW Yanmar 6AYEM-GT marine engines which are designed to minimise fuel consumption and optimise performance
with precise digitally-controlled fuel injection.
Power Equipment supplied the engines and before the build, Power Equipment WA Sales Manager, Nick Marsden, met with the owner
and Shoreline Marine to discuss the advantages of Yanmar’s new electronic, common-rail version of the proven 6AY Series.
Nick says with its 20-litre displacement and a long stroke, the Yanmar 6AYEM-GTproduces very high torque.
“Thanks to 500-hour maintenance intervals, long fuel injector life and Yanmar’s renowned low fuel consumption, these engines keep
running costs to a minimum, which is what commercial marine operators require.
“The key to the performance and efficiency of the 6AY Series is the new staggered injection nozzle and patented ‘ASSIGN’ combustion
chamber design. Yanmar originally developed ASSIGN for large bore, low speed propulsion engines, so it allows for a very wide rpm
range and delivers outstanding fuel consumption.”
Because this was the first time 6AY engines with ASSIGN have been used is this type of application, Shoreline Marine’s installation
attracted engineers from Yanmar Japan and Yanmar Asia (Singapore). They visited Fremantle during the Ada Clara’s sea trials to get a first-hand look at performance of the 6AYEM-GT engine and how it performs and suits the Australian commercial fishing vessels.
