Canning

At 200 gross tons, Canning is the 80,758th 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 30 times smaller than the typical vessel on record here. The largest measures 499,167 GT.

Among the 1,471 tugs held here, it ranks 1,007th by tonnage — larger than 20% of that group. Their median tonnage is 393 GT, and the largest tenth begin at 1,733 GT. The flag most often flown by this group is United States (239 ships). The yard that appears most often against it is Damen Shipyards Gorinchem, with 62 hulls on record.

Canning 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; within it this ship is the 56th largest. 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 33 vessels to Cochrane Shipbuilders, with a median tonnage of 555 GT, delivered between 1928 and 2001. See the rest of that yard’s output.

At 31.1 m overall, Canning is 1.2 m shorter than the 32.3 m median for tugs on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5060172 this registry holds 15 other vessels, whose median build year is 1954 and which range from 1929 to 1961. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1954.

Its IMO number, 5060172, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 0×6 + 6×5 + 0×4 + 1×3 + 7×2 = 82 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.
