Well Deck

Exterior approach to well deck
Docking in a well deck

Well decks are decks near the waterline, which can subsequently be flooded by ballasting the vessel (similar to a floating dry dock). They may be used for amphibious operations or repair work.

Design

Well decks are situated aft on the vessel, with a transom stern, as this simplifies access to the space and provides a wide beam without undue impact on resistance. Ample ballast tanks are provided to allow for submergence of the deck. The sides may be elevated to allow a clear walkway, allowing access for moorage or deck machinery.
