In brief
Exxon Valdez was an oil tanker that gained notoriety after running aground in Prince William Sound, spilling its cargo of crude oil into the sea. On 24 March 1989, while owned by the former Exxon Shipping Company, captained by Joseph Hazelwood and First Mate James Kunkel, and bound for Long Beach, California, the vessel ran aground on the Bligh Reef, resulting in the second largest oil spill in United States history. The size of the spill is estimated to have been 40,900 to 120,000 m3 (10.8 to 31.7 million US gal; 257,000 to 755,000 bbl). In 1989, the Exxon Valdez oil spill was listed as the 54th-largest spill in history.

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.
At 112,088 gross tons, Exxon Valdez is the 2,595th 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 19 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 3,060 oil tankers held here, it ranks 340th by tonnage — larger than 89% of that group. Their median tonnage is 22,184 GT, and the largest tenth begin at 149,274 GT. The flag most often flown by this group is Panama (301 ships). The yard that appears most often against it is HD Hyundai Mipo, with 190 hulls on record.
United States is the country of registry for 2,278 vessels in this directory, of which Exxon Valdez is the 1st largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (977 ships), and the median vessel measures 1,706 GT. Browse every ship flagged United States.
Narrowing to both dimensions at once, this registry holds 23 oil tankers flying the United States flag, of which none is larger than Exxon Valdez.
Exxon Valdez was built in 1986, making it 40 years old. It is one of 866 hulls in this registry delivered that year, a cohort whose median tonnage is 4,769 GT; within it this ship is the 9th 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 48 vessels to NASSCO, with a median tonnage of 43,758 GT, delivered between 1960 and 2021. See the rest of that yard’s output.
At 300.8 m overall, Exxon Valdez is 121.8 m longer than the 179.0 m median for oil tankers on record, with a beam of 50.6 m and a draft of 20.0 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8414520 this registry holds 59 other vessels, whose median build year is 1985 and which range from 1984 to 1988. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1986.
Its IMO number, 8414520, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 4×6 + 1×5 + 4×4 + 5×3 + 2×2 = 120 — and the last digit of that total, 0, must equal the seventh digit, 0. It does, so this number is well formed.
