A Certificate of Class can normally only be issued by the society’s committee on the recommendation of their surveyor, following a special survey.
An Interim Certificate of Class may be issued by the society’s surveyor on completion of a survey after all recommendations of the surveyor have been carried out to his or her satisfaction, to enable the ship to proceed to sea pending the processing of the surveyor’s report by the society and confirmation by the society of the ship’s class status. On completion of a scheduled class survey, the surveyor will also endorse the back of the Certificate of Class with the date and place of the survey.
