Appleton Machine Company of Appleton, Wis. recently delivered three identical winches for use aboard a bulk commodities processing vessel to maintain position between supply barges and the oceangoing ship being loaded. The electrohydraulic, self-contained units are capable of line pulls to 140,000 pounds at infinitely variable speeds to 30 feet per minute.
The winches can be operated as automatic constant-tension units, or switched to manual operation when desired. Both modes of operation are available locally at the winch or from a central control room. For improved flexibility, both the line pull and the line speed are infinitely variable from zero to the maximum in any combination.
Appleton designs and manufactures a wide range of marine deck equipment, including all styles of cranes and winches as well as deck fittings. Each design is governed by appropriate regulatory agencies such as the American Bureau of Shipping, U.S. Coast Guard, American Petroleum Institute, and Det norske Veritas. The division serves all sectors of the marine market, including offshore drilling units and support vessels, and oceangoing ships.
Among the major Appleton Marine products are: dual wildcat offshore mooring winch for mooring offshore drillships and semisubmersibles; swivel fairlead and chain stopper, part of a drillship mooring system; three-section, extendable-boom crane rated 1,500 pounds at 38 feet; 300-hp electrohydraulic, hose-handling crane rated 15 metric tons at a 54-foot outreach; and the aluminum Sea-Lift® crane, built to American Bureau and Coast Guard specifications, which features a 360-degree continuous slewing and boom tip braking system to prevent the load from swinging.
