A Delegation of American shipowners from Seattle have been overseeing the trials in Vigo, of two trawl winches manufactured by Ibercisa for Trident Seafoods (founded in 1973) and actual leader in the American seafoods market. Rick Brown and Mike Luchino from the Company as well as Helgi Kristjansson of Naust Marine (Icelandic electronics and ITT Company) who are collaborating very closely with Ibercisa on the design of the electrical drive for their deck machinery and Joe Sweeney, representative from American Seafoods, a Company to which Ibercisa has already supplied equipment in the past for the "Northern Eagle" and with whom they are presently negotiating a new Contract.
The winches on trial will be installed on board the “Kodiak Enterprise” one of Trident Seafood's three factory vessels. 80m in length, it operates in the Bering Sea and the Aletuian Islands catching Alaska pollock and Pacific hake. They are two main electrical trawl winches of 440 KW each with stowage capacity of 2,000 metres of 35 mm wire. The machines have a nominal pull of 57,8 tons on the first layer at a speed of 40 m/min, this increases by 40% and 80% on pull and speed respectively. Both winches have electronically driven stowage.
Today many fleets are renewing their vessels, particularly the Russian trawlers operating in the Far East, the Norwegian and Icelandic fleets and the big North American trawlers, to incorporate electrical drive: a technology in which Ibercisa has become a market leader. The electrical drive on this type of machinery destined for work at sea is becoming a must, not only because of the advantages and savings in costs but also because it is far more environmentally friendly and much safer in terms of contamination risks.
These are not the only benefits of electrical drive. By eliminating all the tubes, installation costs are reduced as well as energy consumption, maintenance and noise levels, improving the health and safety benefits to workers. Machine ignition by alternating current with frequency converter, an alternating current motor (AC), a gearbox on the winch, a refrigeration system for the motors and an electrical generator. Maximum levels of efficiency of the winch are achieved in terms of (input/output) power due to the ability to generate more power during the free payout also improving the vessel's consumption of energy. The efficiency of electric ignition is around 85%-90% compared to the hydraulic system which can vary between 50% and 70%. Better control than the hydraulic system is also achieved by the variable speed of 2%-100% of maximum rpm and the entire torque at any rate of rpm.
