Supervision of repair work
Typically, all work related to dry docking, repair and maintenance of the vessel is carried out under the supervision of the ship's captain. Additions to the original terms of reference should not be implemented without the permission of the manager or company. It is the responsibility of the ship's personnel to carefully inspect and confirm the satisfaction of all repairs, as well as to monitor quality and report any defects to the Superintendent. Regular meetings between the ship's senior officers, Superintendent
and the repairmen are on schedule.

monitor progress and discuss difficulties and work
Before entering dry dock, the C/E is responsible for ensuring that bilge wells and engine room tank tops are as dry as possible and that all double bottom tank covers are in place and secured. Fire pumps, sanitary pumps and sewer pumps must be isolated when the ship is in dry dock and the shore fire main is connected.
Before the ship enters dry dock, the C/E and C/O must discuss and decide on the allocation of both ballast and bunkers to obtain the correct docking condition and thus avoid undue stress on the hull when the ship takes on blocks. Records of the draft of the bow and stern parts of the vessel, as well as of sediments or failures of water or oil in double-bottom tanks, peaks, cofferdams and bunker compartments, must be contained in the air and deck log books.
Inspection of the Dry Dock (senior mechanic vacancy)
When the dock is dry, the outside and bottom of the hull, propeller, rudder, etc. should be inspected by the captain, chief engineer and company representative to ascertain the condition of the vessel and whether there is any damage from the previous docking.
Certificate Without Gas
During maintenance periods, no premises shall be considered gas-free unless a gas-free certificate has been obtained and maintained. The certificate must state whether the premises are gas free for hot operation or entry only.
Boiler purging
If it is necessary to steam the boiler during dry docking, it is necessary to secure the purge valves and cocks to prevent accidental discharge into the dry dock. Bleeding valves on the sides of the vessel must be open when docked.

Before flooding the dock, the C/E and foreman will ensure that all drain plugs are installed correctly and that all marine valves are closed. All such plugs must be held by C/O when removed. The distribution of weight and trim of the vessel when leaving a dry dock should be the same as when entering it. Special permission must be obtained from the Chief Surveyor in charge of the repairs and from the dock authorities for any deviation from these instructions.
C/Es are station officers to inspect all marine connections and make hull repairs during a dry dock flood. Flooding must be stopped before the vessel is lifted from the blocks, and a full survey must be carried out to ensure that the vessel is watertight.
