Bow Couplings

Our bow couplings consist of two assemblies. One fixed to the dredger, for example a trailing suction hopper dredger, and the other part fixed to the floating and flexible discharge line. This line will be hoisted to the fixed assembly and inserted in the case. After insertion the flexible assembly is clamped by two heavy duty locking clamps. The closing of the bow coupling and the locking of the bow coupling clamp due to hydraulic cylinders.

When opening the clamps by hydraulic cylinders, the flexible coupling assembly will be dis-coupled and removed from the case assembly. This can be done fast and safe without the involvement of staff at the assembly itself.

Benefits of Bow Couplings

Short time

The couplings can be coupled and dis-coupled in very short time.

Coupled and dis-coupled

Safe way of coupling and dis-coupling of the complete bow coupling or the quick release coupling.

Control

Remote control and local control of the coupling is possible.

  • Standard flanges provided, custom flange optional

Options

  • The coupling can be supplied with structure to be installed on the vessel like on trailing suction hopper dredgers
