Steel painted bow coupling

Dredge Bow Coupling are used to connect a floating discharge line to a hopper Dredger. The connecting procedure is fully automated. The working pressure rating is 10, 20, and 30 bar, inter diameter of pipe range from 500mm to 1000mm, winch pull range from 125kn to 400kn. 

Product advantages

High accuracy, fully welded, painted construction

BV certificate

highest degree of flexibility

Easy to maintain

The specifications of our bow coupling

A.    General

High accuracy, fully welded, painted construction can be used for deck pipeline and the shore pipe connection on trailing Suction Hopper Dredger.

B. Construction and procedure

The bow coupling installation mainly consists of a welded Steel Frame, which is mounted on the fore threstle 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.

Procedure: 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 construction is to be built according to the drawing with rules of good workmanship.

With wear plate welded in inlet tube to ensure the long service life

C. Materials

All fabricated steelwork used in the construction will be to manufacturing standard of normal or classification society.

All materials proposed will be selected to comply with the latest Health and Safety Rules.

Paint systems for hull protection will be of the highest quality (Hempel, Inter, Sigma, Jotun)
