1. Harmonized System of Survey and Certification (HSSC) Guidelines requires a minimum of two inspections of the outside of the ship's bottom during any five-year period. One such inspection is to be carried out on or after the fourth annual survey in conjunction with the renewal of the Cargo Ship Safety Construction Certificate or the Cargo Ship Safety Certificate.

2. Further, it provides that inspections of the outside of the ship's bottom should normally be carried out with the ship in dry dock. However, consideration to alternate inspections with the ship afloat may be given by the Administration.

3. In this regard, Panama Maritime Authority vide MMN -006/2022, has informed that ships meeting the requirements of IACS Recommendation No. 133 (Guidelines for Pilot Schemes of Extended Interval between Surveys in Dry-Dock - Extended Drydocking (EDD) Scheme ) may be permitted to carry out two (2) consecutive in-water surveys instead of dry docking and have a privilege to extend their dry docking period from 5 to 7.5 years, subject to the approval of Classification Society (IACS only) and Administration/Flag State and under the following conditions;
