Ship Classification is a mechanism by which the international shipping industry regulates itself. Ship Classification implies development of rules (standards) for the construction and maintenance of a ship's structure and essential engineering system and implementation of such rules in new building and existing ships to ensure the safety of the ships. The classification service of IRS has been now extended to cover all types of ships, craft and floating structures.

Classification of New construction

Design Appraisal

IRS carries out design appraisal of new buildings to ensure compliance with its Rules and Regulations. These cover hull structures, engines, generators, steering gears, propeller, electrical, piping and control systems, and other major machinery components.

Survey during construction

During construction, IRS surveyors regularly verify the material at shipyards, supervise welding procedures and welder's performance qualification test, check fabrication during all stages of construction, witness destructive tests, inspect all essential machinery during manufacturing installation on board at the shipyard and the witness final dock trial and sea trial. IRS surveyors also attend at various manufacturers' works to witness testing of material for construction and inspect essential machinery and equipment at various stages of construction. All these are done to ensure that the approved plans are followed, approved material and components are properly installed, good workmanship practiced and applied, and the Rules adhered to.

Survey After Construction

Maintenance of the IRS Classification is assured by the system of periodic surveys to ensure continued compliance with its Rules. These include various surveys of hull and machinery on a Continuing basis.

Classification of existing ships

Existing ships, not built under IRS supervision, can also be classed with IRS only after ensuring conformity with IRS Rules.
