KEY: DWT = deadweight tons; N = data do not exist; RO/RO = roll-on/roll-off vessels.

NOTES

Excludes non-merchant type and/or U.S. Navy-owned vessels currently in the National Defense Reserve Fleet.

Excludes ships operating exclusively on the Great Lakes and inland waterways and special types such as: channel ships, icebreakers, cable ships, and merchant ships owned by military forces.

All yearly counts are from January of that year.

MARAD has recently reverted back to regarding the merchant fleet as vessels of 1,000 gross tons and greater. They will no longer publish the fleet using “10,000 DWT and greater” as a criterion. Therefore, this report is not comparable with the previous' issues.

The vessel categories used for this report include the following types:

Tankers: Petroleum Tankers, Chemical Carriers, LNG Carriers, LNG/LPG Carriers, LPG Carriers.

Container: Fully Cellular Containerships.

Dry Bulk: Bulk Vessels, Bulk Containerships, Cement Carriers, Wood Chip Carriers, Ore/Bulk/Oil Carriers, Bulk/Oil Carriers.

Ro-Ro: Ro-Ro Vessels, Ro-Ro/Containerships, Vehicle Carriers.

General Cargo: General Cargo Carriers, Partial Containerships, Refrigerated Ships.

ITB: Integrated Tug/Barge
