Markey Machinery Supplies Hawser Winch For LOOP Emergency Response Vessel

A Markey Machinery Co.,Inc., type DUSS-71 single drum hawser winch was provided to Edison Chouest Offshore, Inc., recently for service aboard a new emergency response vessel built at North American Shipbuilding and owned by L.O.O.P. Offshore, Inc.

This single drum winch design has a capacity of 700 feet of 14-inch circumference synthetic line, and uses a two-speed hydraulic motor configuration to achieve line pulls up to 25,000 pounds with speeds of 0 to 200 feet per minute.

To accommodate the large braking capacity requested by the customer, two self-energizing band-type brakes were used to produce a total capacity of 500,000 pounds. Brake air cylinders are integrated with the winch controls for automatic operation of each brake, and handwheels are provided for auxiliary manual brake engagement.

"Built for Strength and Durability," according to Markey, a tubular winch frame reduces the overall weight of the machine, and facilitates winch maintenance with its open design. Self-lubricating plastics, wear resistant materials, and heavy rolled stainless steel brake drums are used to keep maintenance to a minimum, while enhancing the reliability of the winch.

On-call 24 hours a day, the L.O.O.P. ERV must rely on this machine to perform at any moment, in all types of operating conditions.

Markey Machinery Company, Inc., Seattle, has been supplying deck machinery for over 80 years.
