satisfactory condition and operation;
       there is an adequate supply of flush water to clear toilet pans and to replenish water seals, and
       drains and air vents are clear of obstructions and are in sound water/gas tight condition throughout their length.
Adequate air vents should be fitted to the piping network, paying special attention to the extremities of the system. These should ensure an adequate supply of air and prevent plugs of water from breaking the water seal during violent rolling or pitching.
Ventilation systems to all compartments of a ship should be designed, installed and balanced to ensure satisfactory distribution of air. They should be maintained in a clean and efficient condition to achieve the designed air changes throughout the service life of the vessel. Particular attention should be paid to the exhaust or extraction systems in toilet or washing areas. In general, attention should be paid to the examination of extraction grilles, louvres, ducts etc. to ensure that they are clear and free of accumulated dirt, fluff etc.

   21.                        Offshore Support vessels
This section provides additional guidance for Australian offshore support vessels on how to manage the key risks associated with cargo and personnel transfer, towing, anchor handling and barge work.

Further information is available in the Guidelines for Offshore Marine Operations.

21.1 Risk management
Offshore operations are often complex and hazardous, involving many parties who share responsibility for ensuring these operations are carried out safely. Before commencing any offshore operations, vessel operators must carry out a risk management process (described in section 2 of this Code) in consultation with all other relevant duty holders including the charterer, Offshore Installation Manager (OIM) and operators of any other support vessels carrying out simultaneous activities at an installation.

The outcome of the risk management process should be used by the operator to develop a Safety Management Plan which sets out the health and safety roles and responsibilities and various procedures that the company expects to be followed as part of the safe operation of its vessels.

Offshore installations operate under risk management plans or safety cases approved by the National Offshore Petroleum Safety and Environmental Management Authority. Offshore support vessels may therefore need to comply with additional requirements under the facility's safety case regime which should be discussed and agreed as part of the charter party.

The person in command must discuss with the operator and charterer any provisions of the charter party that may exceed the limitations or capabilities of the vessel to the extent that safety may be compromised. Each vessel should have on board a copy of the charter party before commencing operations so that the person in command and crew are aware of any special
