The process of class assignment starts with the application made by the owner or the builder. The documents relevant to the class applied for are submitted for the review of the society. Materials and equipment are inspected at works. During construction of the ship class surveyors carry out inspections to check that construction is in accordance with approved drawings, that the ship is built to accepted standards, and supervise tests and trials provided for. After completion of the surveys, the class surveyor issues interimclassification certificates to the party applying for the classification and prepares a report for the society. After satisfactory review of the report, the society issues the definitive classification certificates and the class assigned to the ship is confirmed in the register.
