Suction pipe

Suction pipe is suspended from three hinged type gantries.
The intermediate and draghead gantries will be of the “A” frame type and the trunnion gantry of the parallelogram type.

Draghead

California type
Discharge capacity

The unloader is designed to unload gravel, all in sand and gravel and sand in drained condition at an overall average rate of 1000 m³/hr. The dredged material may contain lumps up to 100 mm but 90% will be minus 50 mm with up to 50% sand. The material density, in drained condition, is 1850 kgs/m³ for gravel and 1600 kgs/m³ for sand.
Secondary discharge

At present she is used for aggregate dredging and achieves load-line exemption (the ability to load the vessel beyond the normal draft line), by the facility of having the dump valves. In the event of an emergency, cargo can be dumped or dropped out of the hopper if this is ever necessary.
