Queen of the Netherlands is a Dutch trailing suction hopper dredger ship constructed in 1998. After lengthening in 2009, she was the largest and most powerful dredger in the world. The vessel has been used in high-profile salvage and dredging operations including the investigation into the Swissair Flight 111 crash[1] and in the Port Phillip Channel Deepening Project. It has been called "the world's largest floating vacuum cleaner".[1]

Capability

The ship's dragheads are 6 metres (19.7 ft) wide and can dredge between 55 metres (180 ft) and 160 metres (520 ft) deep. The ship has three hopper discharge options of pumping ashore by pipeline, dumping through bottom doors or

subsea material whilst trailing, collapse and liquify hopper cargo for pumping or degassing natural air pockets in the seabed using the Venturi effect
.

Projects

Queen of the Netherlands has worked on various projects in

The Maldives. She has a sister ship called Fairway, which, like Queen of the Netherlands was also lengthened for land reclamation projects in the Far East. The ship has caused controversy in Australia, sparking protests.[4]
