Definitions and procedures related to Classification Surveys

IMO

Period of certificate of class

The period of the certificate of class starts either from the date of initial classification or from the credited date of the last class renewal/special survey, and expires at the due date assigned for the next class renewal/special survey. The due date is the end of the time window for that survey.

Anniversary date

The anniversary date is the day and the month given in the certificate of class which corresponds to the expiry date of the certificate.

Survey time window

The survey time window is the fixed period during which the annual and intermediate surveys are to be carried out.

Overdue surveys

Each periodical survey is assigned a due date specified by the relevant Rules by which it is to be completed. A survey becomes overdue when it has not been completed by its due date. For example, with an anniversary date of 15th April, the annual survey can be validly carried out from 16th January to 15th July. If not completed by 15th July, the annual survey becomes overdue and class will be suspended automatically.

Recommendations/Conditions of Class

‘Recommendation’ and ‘Condition of Class’ are different terms used by IACS Societies for the same thing, i.e. requirements to the effect that specific measures, repairs, surveys etc. are to be carried out within a specific time limit in order to retain class
