Quick Answer The Safe Manning Document (SMD) is issued by the flag state for each individual ship, specifying the minimum crew required to operate it safely. It lists required officers (by certificate level), ratings, and sometimes special qualifications. SOLAS requires it to be kept onboard and followed. A ship operating below its safe manning levels can be detained by Port State Control.
Safe Manning Document: What It Means
The Safe Manning Document is the official ruling on how many qualified people are needed to run your ship.
Every ship is different — a small coastal tanker needs fewer officers than a 300-metre container ship. The SMD is a ship-specific document that sets the legal minimum.
What It Contains
A typical Safe Manning Document specifies:
Deck Department:
- 1 × Master (STCW II/2 certificate)
- 1 × Chief Officer (STCW II/2)
- 1 × OOW (STCW II/1)
- 1 × Additional OOW (on ships requiring 2-watch system)
Engine Department:
- 1 × Chief Engineer (STCW III/2)
- 1 × Second Engineer (STCW III/2)
- 1 × Engineer officer (STCW III/1)
Ratings:
- Minimum number of AB deck ratings
- Minimum number of engine ratings
Special requirements:
- GMDSS operator certificate
- Tanker endorsements (if applicable)
- ECDIS trained officers
SOLAS Connection
SOLAS Chapter V, Regulation 14 requires all ships to be manned at a level that is safe and appropriate for:
- Navigational watch
- Engine watch
- Security duties (under ISPS Code)
- Emergency response (fire, flooding, abandon ship)
IMO Resolution A.1047(27) provides guidelines on minimum safe manning principles — flag states use this to set their SMD standards.
Real-World Relevance
For officers: If you join a ship that appears to be undermanned (e.g., Chief Officer doing OOW watches constantly, no adequate rest), check the SMD. If the actual manning doesn’t match the SMD, this is a reportable deficiency.
For cadets: The SMD doesn’t count cadets as part of the minimum complement — cadet positions are in addition to minimum manning.

Frequently Asked Questions
Who issues the Safe Manning Document?
The flag state (the country where the ship is registered) issues the Safe Manning Document for each vessel. For a Panama-flagged ship, the Panama Maritime Authority issues it. For an Indian-flagged ship, DG Shipping issues it. The document is specific to each individual vessel — one SMD per ship.
What does the Safe Manning Document specify?
The SMD specifies: the minimum number of officers (Master, Chief Officer, 2nd Officer, 3rd Officer, Chief Engineer, 2nd Engineer, etc.), minimum number of deck and engine ratings, required certificates for each position (e.g., STCW II/1 for OOW, III/1 for engineering watch officer), and any special endorsements needed (tanker, GMDSS, etc.).
What happens if a ship sails below minimum manning?
Sailing below minimum safe manning is a Port State Control deficiency. The ship can be detained until the deficiency is corrected — which means sourcing additional qualified officers from shore. The Master is personally responsible for not sailing with inadequate crew. Companies face financial penalties.
Where is the Safe Manning Document kept on a ship?
The SMD must be kept onboard at all times and posted in a prominent place — typically on the bridge. Port State Control inspectors check it against the actual crew list during inspections. If the current crew doesn't meet the SMD requirements, the ship faces detention.
