What Are Flag State Inspections & Classification Surveys?
Flag State inspections and classification surveys are important parts of the international system used to verify that ships meet applicable safety, construction, environmental and operational requirements.
A ship operates under the jurisdiction of the State whose flag it is entitled to fly. Flag State Administrations are responsible for implementing and enforcing applicable international requirements on their ships. Depending on the legal framework and authorization arrangements, surveys and certification may be carried out directly by Administration officers or by authorized recognized organizations and nominated surveyors.
Classification surveys are related to technical rules for ship construction, machinery, structural integrity and continued class. Classification societies establish technical standards and carry out surveys to verify that vessels continue to meet applicable class requirements.
Although statutory and classification survey systems are closely connected, they are not identical. A marine professional working in inspection, surveying, ship management or technical compliance should understand the difference between Flag State responsibilities, statutory certification, recognized organizations, classification requirements and Port State Control.
Official framework: IMO explains that ships are surveyed and verified by Flag State Administrations or authorized organizations so that relevant statutory certificates can be issued. The IMO Code for Recognized Organizations provides a framework for the assessment, authorization and oversight of recognized organizations.
