Shoalway
The Shoalway is a trailing suction hopper dredger, owned and operated by Royal Boskalis, originally intended for the British market and built in 2010.
Design
The vessel was the first of four ships designed by Conoship International and D.W. den Herder maritiem, with a shallow draught and high manoeuvrability for difficult port construction, maintenance, land reclamation, coastal defense and offshore energy projects. The typical carpentry needed for a vessel of this kind was completed by Hans Dorgelo. It was the first dredger in the Boskalis fleet to use azimuth thrusters as its main means of propulsion. The ship is equipped with rainbow discharge valves for beach replenishment or land reclamation, two jet water engines for sediment dispersal, non-protruding bottom doors in the hopper for dumping at sea and engines designed to stringent MARPOL sulphur emissions standards.
Capabilities
Equipped with a suction pipe with a diameter of, a dredge pump of, two jet pumps of and a maximum dredging depth of the ship is able to pump its load ashore by pipeline, dumping or rainbowing.
Its sister vessels of the Shoalway class include the Causeway, the Strandway and the Freeway.
