The TW-1.0 Light Weight Taut Wire is a DP position reference system; which is designed for use as a deck-mounted sensor on surface vessels. The purpose of the unit is to provide accurate data of a surface vessel’s movements with respect to the position of a depressor weight on the sea bed. A 4.9mm wire is maintained at a constant tension due to a 460Kg depressor weight on the sea-bed and an electrically driven winch operating in a heave compensation configuration. This is achieved using a full vector controlled variable speed drive. Vessel movements cause the tensioned wire to deviate from its initial angle; moving the gimbal head sensor which sends the updated signal to the DP system via the programmable automation controller.
