Naval Architects employed by Classification Societies as Ship Surveyors are engaged world-wide in evaluating the safety of ships and marine structures using the Society's Rules and those of intergovernmental organisations such as the International Maritime Organisation. Plans of ships to be built and eventually classed with the Society are scrutinised, and aspects of design such as strength, stability, and lifesaving approved before construction.
During construction, Ship Surveyors carry out inspections to ensure that the quality of the workmanship and materials used is in accordance with the Rules and Regulations. Once the vessel or structure is in service, Ship Surveyors will continue to carry out inspections to ensure that any serious defects arising from operation are made good and that a safe and seaworthy structure is maintained. Government Departments employ Naval Architects who deal mainly with the framing of safety regulations and the surveying of ships and equipment from the safety point of view.
Ship operators and the Ministry of Defence employ Naval Architects to oversee the construction and repair of their vessels.
