The first fishing vessel to be designed and built with hybrid propulsion and powered by LNG has been delivered by the Cemre Shipyard to owners Lie Gruppen.
The new Libas has been designed by Salt Ship Design for Norwegian fishing company Lie Gruppen and is fitted with a 350m3 MAN Cyro LNG tank, a 6000kW MAN 6L51/60DF main engine, a Renk gearbox and a MAN Alpha3000 propeller system, alongside a 500kWh battery system.
The LNG system is expected to reduce CO2 emissions by 25% compared to conventional diesel propulsion, while adding biogas to the mix could reduce this still further. The major reduction is in NOx emissions, which are reduced by 85%. A challenge the operators face is that Libas will need to bunker at relatively frequent intervals, but this is not seen as a problem as fuel can be supplied at locations along the Norwegian coast and can also be delivered by truck if necessary.
The 86 metre LOA, 17.80 metre breadth Libas is rigged with a Karmøy deck equipment system for purse seining and a package of electric Rapp Hydema winches for its trawl setup, which includes three net drums and three trawl winches, providing opportunities for twin-rig operation on certain species.
According to shipbuilder Cemre, Lie Gruppen are pioneers in this field, with what is seen as an environmentally-friendly, safe, efficient, and comfortable vessel. Its innovative design won the 2018 NorFishing Innovation Award.
Two more pelagic vessels using the same technology, Sunny Lady and Selvåg Senior, are being built at Cemre for Norwegian owners.
