Any member of the technical staff of the classification society. The primary task of classification society surveyors is to survey in order to maintain the standards of construction and condition of ships and machinery, which have been laid down by the society. The secondary function of class surveyors, where their society is approved by governments, is for their surveys to be used as a basis for the issue of statutory certificates relating to safety at sea. Surveyors who are full time employees are generally referred to as “Exclusive” surveyors; the ones employed on a part time basis are “Non-exclusive” surveyors.
