Factory ship ‘Lira’ after work in Germany

Germany’s Zeppelin Power Systems says the modernisation and re-engining of a 20-year-old Russian factory trawler could be a potentially viable cost alternative to newbuilding and a model for further such conversions.

Tom Todd writes:  The 120.47m long stern trawler Lira has just gone back into fisheries service after extensive modernisation in Germany carried out by Zeppelin Power Systems in co-operation with Caterpillar Marine Power Systems in Kiel and the ship’s owner Gartex.

 ZPS said the task was to modernise the ship’s drive system and integrate it into the existing engine room set-up as well as to evaluate the condition of existing equipment and its links with the drive system with a view to lowering operational costs and increasing efficiency

Built in 1989 by German yard Volkswerft in Stralsund, now part of P&S Werften, Lira is 19.03m wide and of 7,765gt. She was one of a series of 37 Type Moonzund trawlers built between 1986 and 1991 and powered by two SKL 6VDS 48/42-AL2 7,200bhp (5,294kW) engines. Most are still in service and several of them have already been converted into research ships or re-equipped with increased freezer capacities.

The new heart of the Lira are two MaK Type 8M32C main engines each of 4,000kW. The existing gearing, capable of transferring up to 5,830kW was replaced with a ‘double in-single out’ unit from Reintjes. ZPS said the new engines and gearing along with a new electronic remote control device meant that the existing SKL 8VD 26/20 auxiliary Diesels did not need modification, a cost saving for the owners.

With an available total performance of 8,000kW, two wave generators each of 1,500kW and a drive shaft/gearbox/propeller transfer of up to 5,300kW, the trawler “now has a powerful drive plant that is tailor-made to demand”, ZPS said.

Area sales manager Wolfgang Pakebusch said “we estimate that the total overall demand for the modernisation of Russian fishing and factory ships will be high over the next few years. As far as this particular fleet is concerned, well-tailored modernisation could be economically interesting compared withy the purchase price of a newbuilding”, he said.
