Are IMO regulations tough enough to keep national governments from imposing stricter measures?

Donjon delivers aircraft carrier

On July 26, 2007, Donjon Marine Co., Inc.'s 7200-BHP tugboat Powhatan, transported the U.S. Navy Aircraft Carrier Ex-John F. Kennedy from U.S. Naval Station Mayport located in Mayport, Florida to the Naval Station Norfolk in Norfolk, Virginia.

The carrier was delivered by the Powhatan to U.S. Navy supplied assist tugs adjacent to the Naval Base in Norfolk on July 31, 2007.

Donjon made delivery of the JFK as a result of a contract with Earl Industries, a prime contractor to the U.S. Navy, Southeast Regional Maintenance Command (SERMC). To plan and execute the tow, Donjon worked closely with the U.S. Navy's NAVSEA SUPSALV, the U.S. Coast Guard, local pilots and assist tugs beginning in February 2007.
