A trailing suction hopper dredger (TSHD) unites dredging, transport and discharge in one single vessel. As a result, the dredging cycle of a TSHD is split into four phases: sailing empty, loading the hopper, sailing to the discharge area and discharging the load to shore, after which the cycle starts again.
Focus on the discharge of the hopper load, there are four methods available, one of them by pumping ashore the sand or gravels is pumped ashore via a floating pipeline connected to the bow coupling, using a bow coupling float to ease the connection between the bow discharge body with the discharge floating hose dredge pipeline.
The bow coupling float is dimensioned according to bow coupling of the vessel, made out of polyethylen closed cells foam coated with polyurethan skin. Its designs depends on dimension & weight of the discharge floating pipeline.
- Unsinkable, even if damaged
- Long life expectancy
- Reliable
- High impact absorption rate
