Operational Explanation
Class Special Survey and statutory renewal surveys are distinct regimes often coordinated at one docking; UR Z17 Rev.21 is current, while Rev.22/23 are future from 2027/2028.
Regulatory Reference
IMO HSSC; applicable class Rules; UR Z17 Rev.21 current common minimum at release date, Rev.22 from 1 Jan 2027 and Rev.23 from 1 Jan 2028.
Scope of Application
Special Survey supports class; statutory renewals support Convention certificates for the Administration/RO. Apply the Z17 version incorporated in the Society's Rules.
Procedure / How to Complete It
- Prepare separate class and statutory scopes.
- Coordinate attendance/evidence without merging legal effects.
- Check current/future UR implementation date.
- Use suppliers approved for the required activity.
- Record recommendations, conditions and certificate endorsements separately.
Practical Example
One docking hosts Special Survey and statutory renewals, but no single Renewal Survey automatically renews class and all certificates.
