Maintenance of class

Classed ships are submitted to surveys for the maintenance of class, confirmation, or renewal of their term. Usually all ships having a 5-year term are subjected to annual surveys, intermediate survey and confirmation of the term survey. At the end of the term, the special survey is to be carried out. The special survey may be carried out on a continuous basis (continuous survey) or on distributed basis (distributed survey) during the term.
