The waterline is the line where the hull of a ship meets the surface of the water. Specifically, it is also the name of a special marking, also known as an international load line, Plimsoll line and water line, that indicates the draft of the ship and the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy, particularly with regard to the hazard of waves that may arise. Varying water temperatures will affect a ship's draft, because warm water is less dense than cold water, providing less buoyancy. In the same way, fresh water is less dense than salinated or seawater with a similar lessening effect upon buoyancy.
Australian Maritime Safety Authority (AMSA) is an Australian statutory authority responsible for the regulation and safety oversight of Australia's shipping fleet and management of Australia's international maritime obligations. The authority has jurisdiction over Australia's exclusive economic zone which covers an area of 11,000,000 square kilometres (4,200,000 sq mi). AMSA maintains Australia's shipping registries: the general and the international shipping registers.
A marine surveyor is a person who inspects, surveys, or examines marine vessels in order to assess damage, inspect or monitor their condition and that of any cargo on board. Marine surveyors also inspect equipment intended for new or existing vessels to ensure compliance with various standards or specifications. Marine surveys typically include the structure, machinery and equipment and general condition of a vessel and/or cargo. They also involve judging materials on board and their condition. Though a largely unregulated profession, marine surveyors are generally trained specifically for the role and usually selected after thorough evaluation procedures. Their duties apply to a wide range of seafaring vessels.

More than 90% of the world's cargo-carrying ships’ tonnage is covered by the classification standards set by member societies of IACS.
Nippon Kaiji Kyokai is a ship classification society.
The Germanischer Lloyd SE was a classification society based in the city of Hamburg, Germany. It ceased to exist as an independent entity in September 2013 as a result of its merger with Norway's DNV to become DNV GL.
Ice class refers to a notation assigned by a classification society or a national authority to denote the additional level of strengthening as well as other arrangements that enable a ship to navigate through sea ice. Some ice classes also have requirements for the ice-going performance of the vessel.
Polish Register of Shipping,, also known as PRS, is an independent classification society established in 1936. It is a not-for-profit company working on the marine market, developing technical rules and supervising their implementation, managing risk and performing surveys on ships. PRS has been authorized by a number of State Maritime Administrations to act on their behalf. PRS is the only classification societies which has its own team of scuba divers surveyors performing underwater inspections. The Society's head office is placed at 126 Aleja gen. Hallera, Gdańsk, Poland.
Polar Class (PC) refers to the ice class assigned to a ship by a classification society based on the Unified Requirements for Polar Class Ships developed by the International Association of Classification Societies (IACS). Seven Polar Classes are defined in the rules, ranging from PC 1 for year-round operation in all polar waters to PC 7 for summer and autumn operation in thin first-year ice.

CargoMax is a stability and load management software application for marine and offshore industries. It is developed and sold by Herbert-ABS Software Solutions, LLC. First released in 1979, CargoMax was one of the first computerized systems for planning and evaluating ship loading; it is currently one of the most-used software applications for this purpose. It helps determine cargo loading sequences by calculating stability and stress based on ship models created from vessel data: lightship weights, hydrostatic characteristics, tank data, and allowable shear forces and bending moments. Naval architects and engineers from Herbert-ABS customize each CargoMax installation using shipyard drawings and technical data. Different installations also include different sets of features from the program.
The Russian Maritime Register of Shipping (RS) maintains a ship register of the Russian Federation, based in Saint Petersburg, and is a marine classification society.

Ship management is the activity of managing marine vessels. The vessels under management could be owned by a sister concern of the ship management company or by independent vessel owners. A vessel owning company that generally has several vessels in its fleet, entrusts the fleet management to a single or multiple ship management companies. Ship management is often entrusted to third parties due to the various hassles that are involved in managing a ship. For instance, ships could be considered as large factories that travel across seas under various weather conditions for several days at a stretch. These vessels are equipped with several types of machinery that require appropriate maintenance and the associated spares on board. In the scenario of a vessel lacking adequate maintenance, this could lead to the breakdown of the equipment in the middle of a voyage at sea. A breakdown could be an expensive affair. A second scenario would be – a vessel is continuously on the move or under some sort of activity and hence requires to be manned by a competent crew. The documents of the crew need to comply with international regulations, their transportation to and from the vessel must be arranged for, their competencies must align with the requirement of the vessel and must complement the skillsets of the existing onboard crew. Hence several parameters must be considered which is a tedious job.
Vessel safety surveys are inspections of the structure and equipment of a vessel to assess the condition of the surveyed items and check that they comply with legal or classification society requirements for insurance and registration. They may occur at any time when there is reason to suspect that the condition has changed significantly since the previous survey, and the first survey is generally during construction or before first registration. The criteria for acceptance are defined by the licensing or registration authority for a variety of equipment vital to the safe operation of the vessel, such as safety equipment, lifting equipment, hull structure, static stability, ground tackle, propulsion machinery, auxiliary machinery, etc. The SOLAS Convention, specifies safety equipment for commercial vessels operating internationally.
