DESCRIPTION

2022-built 10,000m³ Trailing Suction Hopper Dredger TSHD

1. General Description:
This vessel is a self-propelled trailing suction hopper dredger featuring twin screws, twin trailing pipes, a single deck, steel full-welded construction, a streamlined hull, and a round bilge form. It is equipped with forward, midship, and aft three-point hoisting/lowering trailing pipes, allowing for dual-pipe dredging operations.
A discharge pipe is located at the forward part of the hopper for bow discharging and bow spraying.
The hopper is equipped with conical bottom doors for sediment discharge. The doors can be operated either in groups or centrally.
Each bottom door is opened/closed by one hydraulic cylinder, with display and remote control from the wheelhouse.
The draghead is of a hydraulic backhoe type, weighing 18 tons, with plow/chisel teeth.
Suction/discharge pipe diameter: 900mm. Bow discharge pipe diameter: 750mm. High-pressure flushing water design pressure: above 12 kg.
Loaded draft: 7.0 meters. Speed: approximately 13 knots.
