Title 46 › Subtitle V — Merchant Marine › Part D — Promotional Programs › CHAPTER 551 — COASTWISE TRADE › § 55122
Moving a floating dry dock does not have to follow the usual rule in section 55102 when three things are true: the dock is being used to launch or lift a specific ship for that ship’s construction, maintenance, or repair; a U.S. shipyard that qualifies under section 12103(b) or an affiliate owns and runs the dock; and the shipyard owned or had a purchase contract for the dock before Congress passed the Carl Levin and Howard P. “Buck” McKeon National Defense Authorization Act for Fiscal Year 2015, or had a signed letter of intent before that date. The move must stay within 5 nautical miles of the owning shipyard, except docks with those earlier letters of intent may move between Honolulu and Pearl Harbor. If a dry dock is needed to build Navy ships, the Secretary of the Navy can say the ownership rule is met and use the date December 19, 2017 instead of the earlier NDAA date, if the Secretary finds the dock is necessary and is owned/run by a qualifying shipyard or affiliate, or is state-owned and run by a qualifying shipyard. The Secretary must notify the House Armed Services Committee, House Transportation and Infrastructure Committee, Senate Armed Services Committee, and Senate Commerce, Science, and Transportation Committee within 30 days. A floating dry dock is equipment with side (wing) walls and a deck that can be fully submerged.
