The annual inspection can be done during a three months period before or the three months after the annual date. There should be two docking surveys (DS) during the five years of certificate validity but it is possible to substitute one by an in-water survey which includes a diving inspection. The intermediate survey (ITSS) is done between the ...
The International Maritime Organization (IMO) states that "The International Ship and Port Facility Security Code (ISPS Code) is a comprehensive set of measures to enhance the security of ships and port facilities, developed in response to the perceived threats to ships and port facilities in the wake of the 9/11 attacks in the United States".
Seamanship knowledge and experience is an integral part of Dry-docking. This includes careful planning (of all jobs, tasks and repairs), adequate preparations (eg or painting), dry-docking calculations (primarily stability and upthrust), safety within the dry-dock and checks upon departure (eg plugs returned and sealed).

In-water survey (referred to by various classification societies as IWS, BIS, etc.) is a method of surveying the underwater parts of a ship while it is still afloat instead of having to dry-dock it for examination of these areas as was conventionally done. For cargo ships, two surveys are required within a period of five years. One of these can ...
Initially prompted by the sinking of the Titanic, the current version of SOLAS is the 1974 version, known as SOLAS 1974, which came into force on 25 May 1980, [1] and has been amended several times. As of April 2022, SOLAS 1974 has 167 contracting states, [1] which flag about 99% of merchant ships around the world in terms of gross tonnage. [1]
A floating dry dock is a type of pontoon for dry docking ships, possessing floodable buoyancy chambers and a U-shaped cross-section. The walls are used to give the dry dock stability when the floor or deck is below the surface of the water. When valves are opened, the chambers fill with water, causing the dry dock to float lower in the water ...
The FSS Code or International Code for Fire Safety Systems is a set of international treaties organised by the International Maritime Organization (IMO) under the SOLAS Convention that are designed to reduce the risk of fire, and aid in emergency response aboard ships. [1]
Repair of fibreglass shaft coating is generally done in a dry habitat mounted over the shaft, allowing access through the open bottom for the divers. The shaft is first cleaned before wrapping with a new layer of sheathing. [6]: 2, 4 Underwater welding is either done in a submerged dry habitat or wet. Better quality welds can be achieved in dry ...
