Campbell Launches Another GM-Powered Superseiner

Campbell Industries of San Diego recently launched another tuna superseiner in its current series. The 1,200-ton-capacity Coopeatun II was built for Cooperativa de Pescadores del Pacifico, R.L. of Puntarenas, Costa Rica, and will be skippered by longtime tunafishing veteran Tim Tafova.

True to his promise to continually update Campbell vessels, president Peter G. Schmidt pointed out some arrangement modifications made aboard the Coopeatun II. The more important revisions involve the relocation of upper engine room elements, including the hydraulic power pack and refrigeration compressors.

"These are very practical changes," Mr. Schmidt said, "primarily because they result in more efficient piping systems that are more readily installed and serviced." Provisions have also been made for future helicopter operations and the installation of scanning sonar, though such items will not be part of the ship's gear when she first sails in early September. Additionally, the Coopeatun II is the first Campbell seiner to carry a MARCO 350-hp bow thruster. The unit is driven by a Caterpillar 3406TA diesel.

The Coopeatun II is 221 feet 5 inches long with a beam of 40 feet 3 inches and a depth of 26 feet 10 inches. She will cruise at about 16 knots with power provided by a General Motors EMD 20-645-E7B diesel rated at 3,600 bhp at 900 rpm. The main engine drives a five-bladed stainless-steel Coolidge propeller through a Falk reduction and reversing gear at a shaft speed of 179 rpm.

Auxiliary power comes from four Cater- pillar D353TA diesels, three of which drive KATO 3 0 0 - kw 440-volt generators. The fourth unit drives the fishing machinery through a MARCO HPD pump drive unit, with backup power provided by another MARCO HPD coupled to one of the generator drive sets.

The Coopeatun II will be fully outfitted to fish the world's oceans, featuring MARCO fish deck machinery highlighted by the WS- 444 purse seine winch with independent drum drive. On a previous Campbell tuna superseiner, this model winch pursed a 750- fathom net in 12 minutes 35 seconds. Also provided by MARCO are a 56-inch Puretic Power Block, power block inhaul winch, anchor winch, brailing winch, corkline winch, and main boom topping winches. Main boom vang winches are by Gearmatic.

In keeping with her up-to-date refinements, the Coopeatun II carries a full complement of today's complex electronics and navigational aids. There are two radars, a depth sounder, weather facsimile system, and an ADF, all by Furuno, along with Sperry's gyrocompass, autopilot, and 8T magnetic autopilot.

The ship also carries a Magnavox satellite navigation system and a wide variety of communication sets and related equipment.
