The Queen of the Netherlands is a Dutch trailing suction hopper dredging ship constructed in 1998. 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]
The ship's draghead is 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. The ship's hopper is among the largest in the world.[2] The ship has equipment to dredge almost any material; the Port Phillip Channel Deepening Project will likely see it remove 23,000,000 cubic metres (810,000,000 cu ft) of clay, silt, sand and limestone from the bottom of Port Philip Bay.[3] During the Swissair Flight 111 salvage operation, a mixture of sea water, silt and aircraft pieces was pumped out of the Atlantic Ocean. The ship assisted in the recovery of nearly 98% of the aircraft, with over 144,698 kilograms (319,000 lb) of aircraft and cargo pieces salvaged.[4]
