Recently delivered to Pesquera Cazador SA, whose principal partners are Norwegian fishing vessel owners, the trawler/seiner Cazador has been protected throughout, against corrosion and abrasion, by Jotun Paints coating systems (Plate 1). The vessel(Hull No. 115) was built at the Astilleros y Servicios Navales SA (Asenav)shipyard, Valdiva, to a Vik and Sandvik design, and the coating contract was won by Industrias Ceresita SA, the Jotun group's Chilean company.
The Cazador has been built to the highest Det Norske Veritas' classification (1A1 Fishing Vessel), has a fish-hold capacity of 1,800m3, and a refrigerated seawater cooling system rated at 450m3, 18°C to 0-1°C in 5-6hr. Designed for a speed of 18.3 knots, she has a total length of 74.5m,breadth on frame of 12.6m, and a depth (first deck) of 8.2m. The vessel has accommodation for 20 people.
Industrias Ceresita worked in close conjunction with owners and shipyard, both during the planning stages and throughout the coating contract. Jotun Paints manufactures a range of marine coatings and, using carefully chosen products from this range, systems were formulated to give the best possible protection in each of the Cazador's differing working areas.
For the hull below the waterline, the Jotun system comprised Marathon mineral-flakereinforced epoxy coating, Safeguard coal-tar epoxy, and Seamate HB 66 self-polishing antifouling. Marathon offers long-term protection in the toughest of working conditions, and was also chosen for the fish-hold of the Cazador. Seamate HB 66 offers up to 60 months antifouling protection for vessels with speeds of six to 18 knots.
The topsides of the Cazador,together with her superstructure, were treated with Penguard epoxy primer,Primastic Universal epoxymastic and Pioner Topcoat.
The protective system chosen for the vessel's external deck, external bridge deck, tween deck and netbin bulwark consisted of Penguard epoxy primer and Jotamastic 87, which is Jotun's well known premium epoxymastic treatment, giving optimum protection in arduous working environments. A low-temperature version of Jotamastic 87 was also used for the bilge engine room.
Plate 1 The trawler/seiner Cazador was the first fishing vessel to be built in Chile for Norwegian owners. With a fish-hold capacity of 1,800m3, she is protected against corrosion and abrasion by Jotun Paints' coatings. The coating contract was won by Jotun group's Chilean company, Industrias Ceresita SA, Santiago
For the protection of ballast tanks, Balloxy HB Light, Jotun's specialist coating, was chosen for the Cazador. A modified epoxy treatment with good penetration, this product is also stated to be free from the hazards of isocyanate and coal tar. Balloxy HB Light is not only light in colour to help application and inspection in dark restricted spaces, but also offers visual control over both mixing and applied thickness.
