Floating dredge hoses
Configured for optimum
performance
Floating dredge hoses are an important part of the
discharge process. Attached to the pivot bend on a cutter
suction dredger or the bow coupling on a trailing suction
hopper dredger, they must be very flexible and robust
for the most challenging of working environments and to
match customers’ needs.
IHC offers an innovative range of professional and highperformance floating hoses for slurry transport to the
shore. Depending on the environmental circumstances,
a combination of several different discharge hoses
and pipes are necessary for the discharge process. For
optimum lifetime, customers can choose a specific wear
layer thickness and hose type.
Floating dredge hoses can be combined with IHC’s wide
range of floating pipelines, pipe floaters, ring floats,
pontoons, etc.
IHC utilises a simulation programme that provides a
dynamic analysis of the movements of the discharge line
and calculates the required configurations. The results of
these simulations dictate the specific arrangements to be
made for each set of circumstances.
IHC’s floating dredge hoses are also exposed to a wide
range of tests prior to delivery – to ensure the Royal IHC
quality standard.

Hose types
All floating hoses are available in three executions, which
are configured according to the soil type which is being
processed:
• Integra type
Standard floating hose, which is made with a rubber
wear liner. This is most suitable for discharging
less abrasive materials, such as clay and silt.
• Armoured type
Floating hose with high-tensile forged steel rings for
applications in rather abrasive slurries, such as sand
and gravel.

• BoneCrusher® type
Floating hose for heavy cutter applications and
highly abrasive material, such as rocks. The patented
BoneRing® shape of the forged steel rings causes a
weight reduction of 15-25% and prevent the rings from
breaking out of the rubber lining.
