Entering Ships into Dry Docks Prior to a vessel entering a dry dock it would be usual practice for the company or the Master of the ship to ensure that the manager of the intended dry dock is furnished with the necessary documentation in order to prepare the dock itself to receive the ship on arrival. The essential details would be the ship’s general particulars together with the dry dock plan of the vessel (often referred to just as the ‘docking plan’). En route to the dock, communication between ship and dock manager would establish the draughts and trim that are required for a normal routine entry. Where entry is to be made when the vessel is in a damaged state, the required draughts and trim may not be possible to attain. In such a case, the damaged vessel would either probably be designated to a floating dock, where the dock can be trimmed to suit the angle of the hull, or directed to a lay-by berth where corrective action may be possible to reduce any list, to suit a practical docking pattern. When controlled entry into a dock is to take place, the ship’s Master would ensure that the following actions are taken:
• Turn stabilisers into their stowed position. • Withdraw any engine room bottom speed logs into the stow
position. • Lower any cranes or derricks to the stowed seagoing
position. • Place all hatch covers and athwartships beams into position
to ensure continuity of strength throughout the length of the vessel.
