CHAPTER 2 | RENEWAL SURVEY
2.2 DRY-DOCK SURVEY
2.2.1 A survey in dry-dock should be a part of the renewal survey. There should be a minimum of two inspections of the outside of the ship’s bottom during the five year period of the certificate. In all cases, the maximum interval between bottom inspections should not exceed 36 months.
2.2.2 For ships of 15 years of age and over, inspection of the outside of the ship’s bottom should be carried out with the ship in dry-dock. For ships of less than 15 years of age, alternate inspections of the ship’s bottom not conducted in conjunction with the renewal survey may be carried out with the ship afloat. Inspection of the ship afloat should only be carried out when the conditions are satisfactory and the proper equipment and suitably qualified staff is available.
2.2.3 If a survey in dry-dock is not completed in conjunction with the enhanced survey during renewal survey or if the 36month maximum interval referred to in 2.2.1 is not complied with, the Cargo Ship Safety Construction Certificate should cease to be valid until a survey in dry-dock is completed.
2.2.4 The overall and close-up survey and thickness measurements, as applicable, of the lower portions of the cargo holds and ballast tanks should be carried out in accordance with the applicable requirements for renewal survey, if not already performed.
Note: Lower portions of the cargo holds and ballast tanks are considered to be the parts below light ballast water line.
