Bow couplings

The process of transporting dredged soil from a hopper dredger to its final location - exactly where it is needed - without the need for an additional vessel typically requires a floating pipeline from ship to shore, powerful pumping capacity and a special link between pipeline and vessel - the bow coupling. Bow couplings offer the opportunity to reduce the time lost between different phases of the dredging process thus raising dredger up-time.

Flexibility key
IHC Parts & Services offers fixed and flex bow coupling designs. The Single Flex Bow coupling gives one degree of freedom (pitch); the Double Flex Bow coupling gives two degrees of freedom (pitch and turn). These ?hinged? units can handle difficult sea conditions and do not require a work boat for the attachment of the line. The flex facility reduces loads on the line, increases operating life and reduces time-consuming bad weather repairs. All models are designed to take pipelines between 450 and 1100mm diameter though naturally specials can be made on request.

Original installation and retrofit
IHC Parts & Services bow couplings are strong, and of proven design and performance. Bow couplings can be installed both as original equipment and retrofit. A simple adaptation permits the inclusion of an inclined jet for rainbowing. Universally applicable on all international floating pipelines, bow couplings mean excellent seal quality, a low maintenance, low breakdown character, and excellent price/performance ratio.
