Open data · every figure carries its source

No gross tonnage is recorded for this vessel, so it cannot be ranked by size. Rank is only shown where the underlying measurement exists.
Vessel particulars
Every value is as recorded in the source. Blanks are values the source does not hold — none is estimated from a sister ship or a class average.

Construction
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.
Langstone was built in 1958, making it 68 years old. It is one of 267 hulls in this registry delivered that year, a cohort whose median tonnage is 718 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 37 vessels to Valmet, with a median tonnage of 18,574 GT, delivered between 1952 and 1986. See the rest of that yard’s output.
At 123.6 m overall, Langstone is 4.8 m shorter than the 128.4 m median for reefers on record.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5313919 this registry holds 5 other vessels, whose median build year is 1954 and which range from 1953 to 1958. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1958.
Its IMO number, 5313919, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 3×6 + 1×5 + 3×4 + 9×3 + 1×2 = 99 — and the last digit of that total, 9, must equal the seventh digit, 9. It does, so this number is well formed.

Same yard, same years
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.
