Ice Grace

At 12,348 gross tons, Ice Grace is the 33,053rd 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 2.1 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 494 reefers held here, it ranks 44th by tonnage — larger than 90% of that group. Their median tonnage is 5,893 GT, and the largest tenth begin at 12,345 GT. The flag most often flown by this group is Panama (80 ships). The yard that appears most often against it is Kitanihon Shipbuilding, with 24 hulls on record.

Ice Grace was built in 1988, making it 38 years old. It is one of 920 hulls in this registry delivered that year, a cohort whose median tonnage is 1,512 GT; within it this ship is the 155th largest. Across the whole of the 1980s the registry holds 13,213 vessels, median 3,004 GT. The median build year across the entire registry is 1995.

At 144.6 m overall, Ice Grace is 16.2 m longer than the 128.4 m median for reefers on record, with a beam of 23.6 m and a draft of 10.0 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8706777 this registry holds 32 other vessels, whose median build year is 1988 and which range from 1987 to 1992. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1988.

Its IMO number, 8706777, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 7×6 + 0×5 + 6×4 + 7×3 + 7×2 = 157 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.
