DESCRIPTION: The Dynacon Traction Winch (DTW) system is a cable-handling system designed to deploy, tend, recover, and store up to 10,000 meters (32,810 feet) of 17.29 mm (0.681 inch) fiber-optic cable. The DTW system performs all pulling and storage functions associated with the umbilical. Principal components in the DTW system include a traction winch, levelwind, storage winch, and electro-hydraulic power unit (HPU). Other assemblies include local and remote controls with line in/out, speed, and tension displays, and instrumented overboarding sheaves. Two sets of electro-optical sliprings typically deploy with the DTW when loaded with conducting or F/O cables. The DTW system is a mobile, self-contained winch system that can be installed on ships of opportunity. The system typically travels in two 20-foot open-top ocean freight containers (or on two flatbed trailers) when the drum is loaded. When the drum is empty, the system can travel in one 40-foot open-top container. An SIO technician attends deployment for shipboard installation and testing, and to train shipboard operators. The SIO technician returns at the off-loading port to demobilize the system and supervise packing for return shipment.
APPLICATION(S): The DTW system is typically used for deep sea deployment of ROV’s and other instruments requiring power or F/O service. The system can also accommodate 9/16 inch mechanical cable for dredging, coring, and mooring applications. Synthetic or soft lines can be accommodated for deep coring and other unique applications.
SPECIFICATIONS: see link to specification sheet below
TRAINING REQUIREMENTS: requires SIO technician to mobilize/de-mobilize; shipboard operators trained during mobilization.
