Cascade General Overhauls And Upgrades Russian Factory Trawler Kapitan Nazin

Cascade General has completed the drydocking and electronics upgrade of the Vladivostok-registered Kapitan Nazin, one of the largest factory trawlers in the world. The Russian ship is one of three identical craft - each 347 feet (105 m) long and 10,000-tons displacement - built in Spain in 1993. They are classified by Det Norske Veritas (DNV) to withstand ice to Class 1B and operate year-round off the Siberian coast in the Sea of Okhotsk. The Kapitan Nazin and its 165 crew can process 125 tons of frozen product per day and store up to 3,200 tons in its refrigerated hold before off-loading at sea to a freighter.

Dalmoreproduct Vessel Management of Seattle, which manages this fleet, is engaged in a highly-competitive sector of the fishing industry and needed top quality engineering and a fast turnaround to guarantee maximum fishing time on the distant grounds. Portland Shipyard's extensive facilities were put to immediate use as soon as the Kapitan Nazin arrived. The ship was heavily laden with nets and spare gear on the stern deck. To reduce the draft for drydocking these bulky loads were moved to the berth alongside the vessel, while maintenance work began on the deck gear, fish-processing plant and engine room.

Once up on Portland Shipyard's Dry Dock 1, Cascade General's Voyage & Small Vessel Repair Division removed the Wartsila CP-propeller for overhaul, withdrew the shaft and rudder for inspection, checked the SKF coupling, while blasting and painting the hull and fitting 68 new zincs. The ship's ice-belt abrasion areas were coated with Intershield Inerta 160, the same high-tech paint Cascade General recently applied to one of the U.S. Coast Guard icebreakers, the Polar Star.

New transducer housings, on both sides of the box keel, were constructed from 1" plate to withstand ice impacts and maintain the hull's unusual strength. Twin aft-looking Simrad ITI sonars and an advanced depth-sounder were fitted and connected to the bridge, giving the fishing master unequalled data on the state of the trawl and catch. This switch to the latest "wireless" system to transmit pictures of the trawl will enable the crew to fish more productively and efficiently.
