Senesco Marine of North Kingstown, R.I. launched the largest commercial floating dry dock in the Northeast United States on May 7, 2013. Senesco built the dry dock for Caddell Dry Dock and Repair Co. of Staten Island, N.Y. The dry dock has a lifting capacity of 7,300 LT, is 420 feet long, and has a 100-foot wide open pontoon deck between its 30-foot tall wing walls.
JMS Naval Architects (JMS) of Mystic, Conn. designed the dry dock for Caddell to accommodate large tank barges, tugs, workboats and Coast Guard Cutters. The dock is segregated into 8 pairs of compartments with a safety deck 12 feet above the pontoon deck. The design incorporates large, side openings through the wing walls to allow machinery and personnel access to the pontoon deck. The pumping and electrical systems are designed to match Caddell’s 6 other dry docks to simplify dock operations.
Senesco recently completed extensive modifications to its waterfront facilities in order to launch the dry dock via air bags and to add the capability of performing air bag launches for future large vessel construction and launch projects.
