Seafarer Medical Report (ML5) and ML5 Certificate

What the Seafarer Medical Report (ML5) and ML5 Certificate Are

The Seafarer Medical Report (ML5) documents a seafarer’s medical history and the findings of a maritime medical examination; the ML5 Certificate is the signed, completed certificate issued after the exam. These documents confirm fitness to perform duties at sea, record any restrictions or treatment recommendations, and are commonly required by shipowners, manning agencies, port authorities and insurers. Completion by an approved medical practitioner and clear identification of the seafarer are essential for acceptance by flag states and employers, while secure recordkeeping preserves legal and operational traceability.

Why accurate ML5 records matter for crews and employers

A correct Seafarer Medical Report and ML5 Certificate establish fitness for duty, reduce operational risk, support regulatory compliance and protect employer and seafarer interests in claims or inspections.

Why accurate ML5 records matter for crews and employers

Primary users and stakeholders

Several distinct roles complete, rely on, or review the ML5 and ML5 Certificate.

  • Ship operators and manning agents — confirm crew fitness and manage crew rotations, medical restrictions, and insurance requirements.
  • Maritime medical examiners and clinics — perform examinations, record findings, certify fitness, and retain medical records per law.
  • Seafarers and crewing HR teams — maintain personal medical history, present valid certificates for joining or change of assignment.

Clear role separation — examiner issues the certificate; employer and seafarer share responsibility for timely renewal and secure record retention.
