TANKER DECK MACHINERY MARKET Deck machinery is wide and varied, from articulating cranes to constant tension winches and capstans, all aimed at helping floating vessels perform their missions in all conditions.


Deck machinery manufacturers continue to innovate with advanced and energy efficient technology.

delicate operations aimed at helping floating vessels perform their missions in the most severe conditions. Designs are rugged, endurable, environmentally compliant and high performing. They must be designed to meet strong payloads and support very complex operations. This is particularly true for salvage and dive operations and towing and tug operations for commercial and government settings.

Outfitting New Naval Platforms For example, the Navy’s new T-ATSX class of ships being built at Gulf Island Fabrication’s shipyard in Houma, La., for the Military Sealift Command, will have a MacGregor deck machinery package that includes a main towing and traction winch, offshore crane, triplex shark jaws, towing and pop-up pins, and a stern roller.

The T-ATSX is a towing, salvage and rescue vessel class designed for worldwide naval service deployments, including open-ocean towing, submarine rescue and salvage support operations. The class’s design is based on those of commercial offshore towing vessels, and it will replace the T-ATF and T-ARS 50-class vessels that U.S. Military Sealift Command currently operates. West Creek, N.J.-based JonRie will supply equipment for six Navy YT-808-class tugs built by Dakota Creek Industries, Anacortes, Wash. The agile capability of tugs requires deck machinery that’s not only reliable and fully environmentally compliant, but also durable and works well in tight scenarios where versatility and high performance are required. The 90-foot tugs will have a total power of 2,690 kW and will be used to dock and undock naval ships into berths and docking areas.

rom inside a control booth of an offshore platform, operators view a screen and a logic controller as a high-performing winch lowers their wet bell down into the ocean depths, helping the vessel complete its hydrographic mission. The IHC Hytech Gantry wet bell system, built in cooperation with Romanian-headquartered DMT Marine Equipment, allows two divers and equipment operators to carefully work at a depth of nearly 270 feet below the ocean’s surface. The winch equipment’s containerized double hydraulic, 25 kW power units power a covered gantry handling system along with the DMT winch system that is installed onboard the vessel as a skid and requires no extra deck stiffening.
