Markey Machinery Company of Seattle, Wash., has developed a new Electric Bow Ship-Assist & Escort Winch and Electric Stern General Purpose Deck Winch for Foss Maritime, in response to their application requirements for the new 5,000 hp ASD Tug
, Morgan Foss, constructed at Foss Maritime's Rainier Shipyard
. The type DEPGF-42 Electric Ship-Assist & Escort Winch installed on the bow features a 75 hp electric-motor drive, a drum sized for over 500 ft. of eight in. soft-line, a level-wind fairleader, and an auxiliary warping-head of 24 in. diameter. The high-capacity drum brake will hold well over 400,000 lbs. Markey also outfitted this winch-system with its Line-Tension Display System which shows the operator the tension in the line while the drum brake is set. This winch includes Markey's Render-Recover Mode capability which allows the Captain to operate the Winch in a hands-free manner. This new tug is also outfitted with a new-design Markey type DEPC-32 20 hp Electric Deck-Winch on the stern, with a drum to hold 250 ft. of 6.5 in. soft-line, and with a high-capacity drum brake rated to hold over 200,000 lbs. The new designs are based on Markey's industry-standard soft-line hawser winches for assist-tugs, which allow the winch to be set up for either wire rope or high-performance ropes based
on Plasma or Dyneema fibers
. The new designs also include features which simplify installation and long-term maintenance. Markey has designs available for Ship-Assist & Escort, including newer LNG-specific Escort Winch applications, including versions with below-deck electric motors, explosion-proof motors and brakes, intrinsically-safe controls, and constant-tension drives.
