- For vessels sailing without a radio maintainer on board, at least two (2) deck officers are required to hold the GMDSS-General Operator Certificate. One (1) of the operators shall be designated as having primary responsibility for radio communications during distress incidents. Under these circumstances, there shall be duplicate GMDSS equipment on board, and shore- based maintenance service of the equipment contracted by the vessel owner/operator.
8.0 ECDIS Equipped Vessels: The officers involved with navigation on ECDIS equipped vessels will be certified as meeting the generic training identified in STCW Table A-II/1. The type specific ECDIS familiarization training will be included in the officers’ on board training record.
9.0 Unattended or Periodically Unattended Machinery Operations
In vessels certified for unattended or periodically unattended machinery operations, a sufficient number of qualified personnel must be carried to provide manual control of machinery in an emergency to enable the vessel to reach port. (See Marine Notice MAN-002).
- Persons assigned electrical and electronic duties
- The ship may carry persons who are assigned the specific duties, tasks and responsibilities relating to electrical and electronic tasks. If required to be carried, these persons shall be certified as Electro-Technical Officers or Electro-Technical Ratings and provide certification that they meet the requirements of STCW Regulations III/6 or III/7 respectively.
- The Minimum Safe Manning Certificate will only include Electro-Technical Officers STCW III/6 and/or Electro-Technical Ratings STCW III/7 if the company has assigned duties to satisfy the requirements of:
- The maintenance of a safe engineering watch,
- Emergency as specified in the Muster List, and/or

- Minimum Safe Manning Certificates: The following are the Liberian Administration’s procedures for issuing Minimum Safe Manning Certificates.
- Procedures:
- The scales presented in section 12.2 are standards for general guidance only. Minimum safe manning will be assessed on a ship-by-ship basis upon application to the Administration.
- Subject to the governing principle that the Master is at all times responsible for the safe operation of his vessel, the Master may, in his discretion, vary the numbers of personnel on any watch either by reduction under favorable conditions or by increasing the number of watch standers during unfavorable conditions such as periods of poor visibility or high traffic density.
- To request alternative manning the Administration will need to assess the
- Procedures:
- minimum navigational crew required. To do this we will need to understand how the navigation watch and collateral duties required of the Master, Chief Mate, Navigational Watch Officer(s), and Deck Ratings who stand a navigation watch are distributed in a manner, which will provide opportunities for adequate rest.
- minimum manning for the engine room using the kilowatt (kW) power of machinery. When determining the total kW, the operator shall identify the aggregate of main propulsion machinery routinely operated. In addition, engine room layout and proximity to boiler rooms, etc., may be part of the evaluation. General arrangement plans and other data may be requested.
12.1.4 If a company submits a proposal for a change in the minimum safe manning level of a vessel, the proposal will be evaluated by the Administration to ensure that the tasks identified in reference (g) are addressed:
a. The capability to:
- maintain safe navigational, port, engineering and radio watches in accordance with regulation VIII/2 of the 1978 STCW Convention, as amended, and also maintain general surveillance of the ship;
- moor and unmoor the ship safely;
- manage the safety functions of the ship when employed in a stationary or near- stationary mode at sea;
- perform operations, as appropriate, for the prevention of damage to the marine environment;
- maintain the safety arrangements and the cleanliness of all accessible spaces to minimize the risk of fire;
- provide for medical care on board ship;
- ensure safe carriage of cargo during transit;
- inspect and maintain, as appropriate, the structural integrity of the ship; and operate in accordance with the approved Ship's Security Plan; and
b. The ability to operate:
- all watertight closing arrangements and maintain them in effective condition, and also deploy a competent damage control party;
- all onboard fire-fighting and emergency equipment and life-saving appliances, carry out such maintenance of this equipment as is required to be done at sea, and muster and disembark all persons on board; and
- the main propulsion and auxiliary machinery including pollution prevention equipment and maintain them in a safe condition to enable the ship to overcome the foreseeable perils of the voyage.
c. The following onboard functions, when applicable, should also be taken into account:
- ongoing training requirements for all personnel, including the operation and use of fire-fighting and emergency equipment, life-saving appliances and watertight closing arrangements;
- specialized training requirements for particular types of ships and in instances where crew members are engaged in shipboard tasks that cross departmental boundaries;
- provision of proper food and drinking water;
- need to undertake emergency duties and responsibilities; and
- need to provide training opportunities for entrant seafarers to allow them to gain the training and experience needed.
- The proposed vessel’s complement shall contain the number and grades/capacities of the personnel to fulfill the task, duties and responsibilities required for the safe operation of the vessel, for protection of the marine environment, and for dealing with emergency situations.
- The master, officers, and other members of the vessel’s complement shall not be required to work more hours than is safe in relation to the performance of their duties. The safety of the vessel and compliance with the requirements for work and rest hours shall be taken into account in accordance with applicable national regulations.
- If a General Purpose (GP) manning system is proposed, the Administration will require evidence that the ratings concerned have adequate training and experience. This would particularly apply if the proposed number of General Purpose ratings (GP-1s) is less than the total number required by the BASIC MANNING scales below.
- The Administration will only approve a proposal for the minimum safe manning level of a vessel and correspondingly issue a minimum safe manning document if it is fully satisfied that the proposed vessel’s complement is established in accordance with the principles, recommendations and guidelines contained in reference (g), and is adequate in all respects for the safe and secure operation of the vessel and for the protection of the marine environment.
- Ships with a manning of 10 or more crew shall be provided with a ship’s cook trained and certified in accordance with Regulation A.3.2 of MLC, 2006 and STCW Regulation VI/I. This will be indicated in the Notes on the Ship’s Minimum Safe Manning Certificate. Effective 1 December 2022, the Administration will include this provision on new minimum safe manning certificates for ships with a manning of 10 seafarers or more. All other minimum safe manning certificates shall include requirement for ship’s cooks at the next reissuance of the certificate or no later than 31 December 2023, whichever is earlier.
12.2 Standards for General Guidance (As provided in section 12.1.1, the scales presented in the table below are standards for general guidance only. Minimum safe manning will be assessed on a ship-by-ship basis upon application to the Administration. Operator recommended manning at or in excess of the below scales shall take precedence.)

- Control Procedures
- Flag State:
11.1.1 The Administration will withdraw the minimum safe manning document of a vessel if:
- The company fails to submit a new proposal for the vessel’s minimum safe manning level when the vessel changes its trading area(s),
- There are issues concerning construction, machinery, equipment, or operation and maintenance of the vessel that have taken place which affect the minimum safe manning level, or
- there are clear grounds for believing that the standards or the ability of the seafarers of the ship to maintain watchkeeping standards as required by STCW 1978, as amended, are not being maintained because of any of the following having occurred:
- The ship has been involved in a collision, grounding, or stranding,
- There has been a discharge of substances from the ship when underway, at anchor, or at berth which is illegal under any international convention,
- The ship has been maneuvered in an erratic or unsafe manner whereby routing measures adopted by the IMO or safe navigation practices and procedures have not been followed,
- The ship is otherwise being operated in such a manner as to pose a danger to persons, property, or the environment or the ship’s security has been compromised, or
- The safety inspection and audit record for the vessel indicates that the manning level is not sufficient.
- The Administration will review and may withdraw, as appropriate, the minimum safe manning document of a vessel that persistently fails to be in compliance with requirements or is being operated in such a manner as to pose a danger to persons, property, or the environment or the ship’s security has been compromised.
- The Administration may withdraw and reissue a MSMC to require additional crew for any vessel that persistently fails to be in compliance with requirements concerning hours of work and rest (see section A VIII of International Convention on Standards of Training, Certification and Watchkeeping for Seafarers, 1978, as amended).
13.2 Port State Authorities
13.2.1 Regulation I/4 of SCTW 1978, as amended, enables Port State authorities to verify conditions on any ship, particularly to the qualifications and ability of personnel on board. Port State authorities may pay particular attention to the following:
