Stability and balance
All tanks, where possible, should be hand-drilled before dry docking. An accurate statement about the tank should be attached to the dry dock report. Before the ship enters dry dock, it is necessary to ensure sufficient stability and the necessary trim, and also not to allow the loading, transfer or unloading of water, fuel supplies and other cargo without the permission of the senior officer.
Before leaving dry dock, the distribution of fluids on the vessel must be adjusted to compensate for any changes in weight since entering dry dock. The bilge tank must be emptied before dry docking. The holds should be as dry as possible.
Before dry dock (start as senior engineer)
The main engine must be accessible. Auxiliary tanks for cooling water circulation must be filled and replaced with valves/glass blanks, which must be checked to ensure a smooth transition to dry joint circulation.
All waste water discharges must be closed and the sanitary system shut down during dry docking if unloading facilities are not available.
A fire main connection must be installed prior to drying and adequate pressure maintained throughout the dry docking period.
Power to deck cranes and deck winches must be turned off during drydock operation to prevent unauthorized use.
Documentation
The appropriate dry dock and maintenance forms must be completed and, if possible, all hull plating setbacks in the hull expansion plan must be indicated.
Inspection (start as a senior mechanic)
The hull skin, rudder, propeller and bow thruster, where installed, are subject to visual inspection. Test the propeller roots for cracks and document any damage in the inspection report.
Marine Generators should be used except when essential work needs to be done on the switchboard or cooling systems.
All body sensors should be checked and lubricated before and after spraying. Make sure the anodes are oiled.
Tail shaft wear should be checked against previous readings. Record the clearances between the rudder bushing and the pin.
All seawater inlet filters must be cleaned and inspected.
All ship's side valves must be checked - all valves must be closed before sinking.
The sewer system must be flushed before dry joining, cleaned and inspected indoors. All valves must be checked for proper operation.
Air cylinders must be filled to the brim at all times.
Undocking (start to the position of senior engineer)
Before undocking, the chief engineer and chief mate are jointly responsible for:
The main engine must be accessible.
Inspect the bottom plugs to make sure they are all in the correct position
and stand tight.
Bottom plugs that are removed during dry docking should be under the responsibility of the senior officer.
Ensuring that the class and fairing parts are in place and wired together.
Ensuring that all tank manhole covers are in place and securely fastened
Ensuring the safety of storm valves and all ship side valves below the waterline.
Sound block (start as senior mechanic)
A complete tank sounding set should be taken after the vessel picks up the blocks, and another set taken before undocking.
