In context

How Essex 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.

Essex was built in 1954, making it 72 years old. It is one of 182 hulls in this registry delivered that year, a cohort whose median tonnage is 2,174 GT. Across the whole of the 1950s the registry holds 2,005 vessels, median 960 GT. The median build year across the entire registry is 1995.

The registry attributes 27 vessels to John Brown & Company, with a median tonnage of 21,370 GT, delivered between 1936 and 2013. See the rest of that yard’s output.

At 160.3 m overall, Essex is 31.9 m longer than the 128.4 m median for reefers on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5106639 this registry holds 13 other vessels, whose median build year is 1957 and which range from 1929 to 1960. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1954.

Its IMO number, 5106639, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 1×6 + 0×5 + 6×4 + 6×3 + 3×2 = 89 — and the last digit of that total, 9, must equal the seventh digit, 9. It does, so this number is well formed.

No ship class is recorded for this vessel, so these are not asserted to be sister ships — they are contemporaries from the same builder, shown because that is what the data supports.
