      1. The Master/OIM cannot reduce the minimum number of crew members or qualified persons required by the MSMC. However, nothing in these recommendations should be deemed to impair the right of the Master, OIM, or Person-in-Charge of the MODU/MOU to require any personnel to perform any hours of work necessary for the immediate safety

or security of the MOU, the personnel on board, to effect crew-changes, or for the purpose of aiding another MOU in distress. The Master/OIM may augmenting the numbers of persons on watch in the event of poor visibility or high traffic density, or for other emergency or operational considerations as may be needed for the safety of the

MODU or MOU

The application for an alternative manning by the vessel operator, must demonstrate that safety and security of the vessel, crew and the environment will not be affected. In all instances of reduced manning, it remains the Master’s/OIMs, Chief Engineer's/Maintenance Supervisor’s and owner's responsibility to provide sufficient personnel to cover additional watchkeeping requirements, fire and safety requirements, industrial applications, and maintenance of the vessel or to make adequate alternative arrangements.
      1. The application must include a description of how the vessel can meet the requirements with the proposed reductions in crew, such as: very limited voyages with frequent crew changes, shore side support by visiting maintenance teams, and/or new automated systems that reduce the workload. In the request for a reduction, these operational or equipment advantages must address how the reduced crew can meet all of the tasks and issues presented in 3.11.1.
    1. Control Procedures
    1. Port State or Coastal State Authorities
      1. Regulation I/4 of SCTW 1978, as amended, enables port State authorities to verify conditions on any vessel, particularly to the qualifications and ability of personnel on board. Port State authorities may pay particular attention to the following:
