YM Prominence

At 40,435 gross tons, YM Prominence is the 13,545th 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 6.7 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 58,086 vessels this registry holds no type classification for held here, it ranks 7,579th by tonnage — larger than 85% of that group. Their median tonnage is 5,358 GT, and the largest tenth begin at 54,309 GT. The flag most often flown by this group is Panama (5,698 ships). The yard that appears most often against it is HD Hyundai Mipo, with 615 hulls on record.

YM Prominence was built in 1987, making it 39 years old. It is one of 819 hulls in this registry delivered that year, a cohort whose median tonnage is 1,937 GT; within it this ship is the 54th 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.

The registry attributes 270 vessels to CSBC Corporation, Taiwan, with a median tonnage of 43,605 GT, delivered between 1979 and 2021. See the rest of that yard’s output.

At 269.7 m overall, YM Prominence is 154.7 m longer than the 115.0 m median for vessels this registry holds no type classification for on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8501438 this registry holds 46 other vessels, whose median build year is 1986 and which range from 1985 to 1989. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1987.

Its IMO number, 8501438, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 5×6 + 0×5 + 1×4 + 4×3 + 3×2 = 108 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
