Summary

Movements of floating dry docks can be exempt from section 55102 when certain rules are met. The dry dock must be used to launch or lift a vessel for construction, maintenance, or repair; it must be owned and run by a U.S. shipyard that is an eligible owner under section 12103(b) or by that shipyard’s affiliate; and it must have been owned, under contract, or covered by a signed letter of intent before the Carl Levin and Howard P. “Buck” McKeon National Defense Authorization Act for Fiscal Year 2015 was enacted. The move must stay within 5 nautical miles of that shipyard, except docks moved under a letter of intent may travel between Honolulu and Pearl Harbor. For dry docks used to build Navy ships in a U.S. shipyard, the Secretary of the Navy can treat the ownership rule as satisfied and use the date December 19, 2017 instead of the earlier enactment date if the Secretary finds the dry dock is needed to finish work on time and the dock is either owned and run by an eligible shipyard or owned by the State and run by an eligible shipyard. The Secretary must tell four Congressional committees within 30 days of that decision. “Floating dry dock” means equipment with wing walls and a fully submersible deck.
