The dry dock is a structured area wherein construction, repairs and maintenance of merchant vessels and boats are carried out. The unique construction allows the water to be filled up in an area, also known as a lock so that vessels can be manoeuvred in and out of the area. Once the vessel enters the dry dock, the gates are closed and the seawater is drained out so that hull and other areas of the ship which have been exposed to seawater for a long time are available for carrying out maintenance and repair works. As per SOLAS requirements, all Merchant vessels require a complete inspection of the hull in a dry dock twice within 5 year period and the intermediate survey must not be more than 36 months. This includes maintenance of hull, propeller, rudder etc. Two of such inspections in a period of five years must be carried in dry dock and the maximum interval between these inspections should be 3 years.
