In brief
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 and in the Port Phillip Channel Deepening Project. It has been called "the world's largest floating vacuum cleaner".

In context
Every figure in this section is a count, a rank or a percentile over vessels actually held in this registry — not over the world fleet, which is larger. Nothing here is estimated.
At 33,423 gross tons, Queen of the Netherlands is the 17,000th largest of the 84,014 vessels in this registry that report a tonnage. The median across that set is 5,994 GT, so this hull is about 5.6 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 58,086 vessels this registry holds no type classification for held here, it ranks 9,475th by tonnage — larger than 81% of that group. Their median tonnage is 5,358 GT, and the largest tenth begin at 54,309 GT. The flag most often flown by this group is Panama (5,698 ships). The yard that appears most often against it is HD Hyundai Mipo, with 615 hulls on record.
Cyprus is the country of registry for 1,418 vessels in this directory, of which Queen of the Netherlands is the 367th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (915 ships), and the median vessel measures 15,666 GT. Browse every ship flagged Cyprus.
Narrowing to both dimensions at once, this registry holds 915 vessels this registry holds no type classification for flying the Cyprus flag, of which 233 are larger by tonnage.
Queen of the Netherlands was built in 1998, making it 28 years old. It is one of 1,367 hulls in this registry delivered that year, a cohort whose median tonnage is 7,381 GT; within it this ship is the 233rd largest. Across the whole of the 1990s the registry holds 12,006 vessels, median 4,956 GT. The median build year across the entire registry is 1995.
The registry attributes 1 vessels to Verolme Scheepswerf, Heusden, Netherlands (1998), with a median tonnage of 33,423 GT, delivered between 1998 and 1998. See the rest of that yard’s output.
At 230.7 m overall, Queen of the Netherlands is 115.7 m longer than the 115.0 m median for vessels this registry holds no type classification for on record, with a beam of 32.0 m and a draft of 11.5 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9164031 this registry holds 55 other vessels, whose median build year is 1998 and which range from 1997 to 2001. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1998.
Its IMO number, 9164031, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 1×6 + 6×5 + 4×4 + 0×3 + 3×2 = 121 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
