New generation South Atlantic trawler
The Nodosa shipyard at Marín in Galicia last year delivered two new vessels to fish in the South Atlantic; first specialised toothfish longliner CFL Hunter, and now trawler Monteferro, designed to concentrate on squid but with capacity to also target some fish species.
Monteferro has been built for fishing company Kalamar, a joint venture between Spanish operator Rampesca and Falklands company RBC, and the new trawler operates under the UK flag with a Stanley registration. It replaces one of Kalamar’s older vessels, Kalatxori, while the other, Castelo, remains in operation with the company.
Challenges during the design process were accommodate a crew of 44 in mostly two-berth cabins, with crew conditions in line with the latest ILO requirements, while ensuring that Monteferro remained under 1499gt, as a vessel over 1500gt would fall into another size bracket with fewer available fishing days under the Falklands management regime.
The first of a new generation of trawlers for fishing in the Southern Atlantic, Monteferro is a 63.50 metre stern trawler with a 12 metre beam, fitted with a factory deck designed for optimal flow of catch. Packages catches of illex and loligo squid, depending on the season, are frozen in the bank of eight blast freezers that have a combined throughput capacity of 67 tonnes per day. Monteferro has a sophisticated refrigeration management system, combining frequency converters and R407F refrigerant, with four 132kW and one 75kW Bitzer compressors. Catches are stored at -40°C in Monteferro’s 1320m3 fishroom and middle deck storage area.
Ensuring good fuel economy in an industry where fluctuating fuel costs are a constant problem was high on the list of priorities for Kalamar when looking to build a new trawler and Monteferro has a 2400kW MaK 8M25C main engine, driving a 3700mm four-bladed, ducted Baliño-Kawema controllable pitch propeller through a Reintjes LAF2375 gearbox with a 1:5.87 reduction ratio. Electrical power is provided by the 1345kVa Stamford Tipo shaft generator and a pair of Scania DI16074M gensets.
The deck is laid out with a pair of 35.50 tonne Ibercisa trawl winches controlled using a Scantrol iSYN system at the heart of the all-electric deck equipment system. The winches are designed to route energy back into the ship’s electrical system as the gear is shot away.
The deck machinery as a whole was supplied by Ibercisa, with a 16m3 net drum mounted over the deck and a row of 16 tonne sweepline winches at the head of the trawl deck. In addition, Ibercisa supplied the two 29.50 tonne gilsons, a 19.60 tonne codend winch and 3.60 tonne outhaul winch, as well as the mooring capstan and anchor winch. The three M230.20 deck cranes, each with a 1.20 tonne capacity and a 13.60 metre reach, are from Guerra.
