Dredge Bow Coupling

Description of Dredge Bow Coupling

Hi-sea Dredge Bow Coupling is for TSHD.The bow coupling can be used to attach a floating pipeline to the vessel without the need for an additional vessel. The bow coupling installation mainly consists of a welded steel frame, which is mounted on the fore trestle of the ship and a hydraulic hoisting winch. The steel frame contains a hydraulically operated click-in ball joint, dredge line bend, upper roll for the hoisting wire and optionally a rainbow nozzle. The unit is equipped with an operating panel and a hydraulic control block.

The coupling procedure is easy: connect the floating pipe line to the hoisting wire, hoist into the click-in ball joint and close the click-in. The hydraulic control block will adapt automatically to the increasing hoisting load and will prevent the male part from being pulled into the click-in ball joint too fast.

The bow coupling system is fitted with a unique coupling mechanism to the floating dredge pipeline. The coupling mechanism comprises of a click-in ball joint mechanism (male-part) which is locked and released by a single hydraulic cylinder mechanism. This mechanism is designed to perform in rugged operating conditions; any sand or dirt accumulation will not interfere with the locking and releasing mechanism of the male part.
