How HMS Echo compares

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.

HMS Echo was built in 2002, making it 24 years old. It is one of 1,298 hulls in this registry delivered that year, a cohort whose median tonnage is 12,563 GT. Across the whole of the 2000s the registry holds 18,605 vessels, median 9,957 GT. The median build year across the entire registry is 1995.

The registry attributes 59 vessels to Appledore Shipbuilders, with a median tonnage of 2,985 GT, delivered between 1956 and 2003. See the rest of that yard’s output.

At 90.6 m overall, HMS Echo is 19.6 m longer than the 71.0 m median for research / surveys on record, with a beam of 16.8 m and a draft of 5.5 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9234018 this registry holds 83 other vessels, whose median build year is 2001 and which range from 2000 to 2005. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2002.

Its IMO number, 9234018, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 2×6 + 3×5 + 4×4 + 0×3 + 1×2 = 108 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
