Annual Survey

An annual survey is a classification society inspection conducted once per year, typically within a three-month window either side of the survey anniversary date, to confirm that the vessel's hull, equipment, and machinery remain in a satisfactory condition and that the class conditions from the previous survey have been addressed. The scope of the annual survey is less intensive than the special survey but covers an examination of the accessible structural members of the vessel, all statutory equipment required for SOLAS compliance, and a review of the ship's certificates and logbooks. For vessels subject to SOLAS Safety Equipment Certificates, Safety Radio Certificates, and Load Line Certificates — all of which are renewed at five-year intervals — annual endorsements must be carried out to confirm continued compliance. The chief officer prepares the vessel for the classification surveyor's visit by ensuring all equipment is operational, maintenance records are complete, and any outstanding conditions of class have been satisfactorily resolved. Failure to complete the annual survey within the permitted window results in suspension of the vessel's class, which in turn invalidates the statutory certificates — rendering the vessel legally unable to trade.
