Baydelta Maritime goes with Markey winches

(SEATTLE) — San Francisco headquartered Baydelta Maritime, commissioned a sixth Delta Class Tug with Nichols Brothers Boat Builders out of Whidbey Island Washington. The Jensen designed M/V Delta Audrey, is a 100’x40’ z-drive tractor tug that is set to be delivered in June. The Tractor Tug is ABS load line certified and consists of a complete propulsion system that includes two Caterpillar 3516C diesel engines coupled to the Rolls Royce propulsion package. This system will produce 93 tons of bollard pull with a combined horsepower of 6800, giving the tug exceptional pulling power and maneuverability. The vessel is outfitted with two Markey Winches; one forward for ship assist and one aft for towing. The two winch suite includes the Markey Model DEPCF-52-75HP Class II Hawser Winch and the TES-40 Tow Winch. The DEPCF-52 has a drum capacity for up to 750 ft. of 9-1/2” / 10” soft-line and has a rated performance of 30,800 LBS at 378 ft/min. Included in the package is the Markey Render/Recover ® feature that allows for hands free operation at up to full rated line-speeds and line-tension. The TES-40 is sized for up to 2800 ft. of 2-1/4” wire rope (26 x 48 x 76) with an air-controlled drum brake and drum disconnect clutch and an 18” dia. warping head. The TES-40 rated performance at barrel layer is 154,000 lbs. stall line-pull and 110,200 lbs. running line-pull at 20 ft/min. Together they will share a single VFD drive panel and dynamic braking resistors, while having discrete wheelhouse controls for each winch. This reduces the impact of “below-deck” equipment on available space, as well as system cost while supporting full functionality of either winch. Founded in 1907, Markey Machinery Company is the leader in the design and manufacturing of high quality custom deck machinery for workboat, scientific, and dockside applications.
