On the Navregs  blog writing the front the exploration of SOLAS V continues . This time the focus is on maintenance.

What is the requirements for the maintenance of navigational equipment?

That adequate arrangements are in place to ensure that the performance of the equipment required by SOLAS Chapter V is maintained.

Note This will include ensuring that proper manuals enabling on-board maintenance are available and that that companies have ensured a comprehensive back-up service, including provision of both spares and maintenance engineers by manufacturers or their agents.

Can a vessel sail with defective navigational equipment?

Yes, where repair facilities are not readily available, provided suitable arrangements are made by the master to take the inoperative equipment or unavailable information into account in planning and executing a safe voyage to a port where repairs can take place. In such cases the vessel must obtain approval from their flag state. Approval to sail will not apply to cases when the defects are detected during a safety survey.

The decision to allow a vessel to sale with defective equipment  will depend on the equipment involved, the magnitude of the malfunction and it’s effect on the ship being able to complete the voyage safely.

Equipment manuals and IEC

IEC 60945, issued by the IEC states that equipment manuals must be:

  • Be written in English
  • Identify the category of the equipment or units to which they refer
  • in the case of equipment so designed that fault diagnosis and repair down to component level are practicable, provide full circuit diagrams, component layouts and a component parts list
  • In the case of equipment containing complex modules in which fault diagnosis and repair down to component level are not practicable, contain sufficient information to enable a defective complex module to be located, identified and replaced.

IEC is the international Electrotechnical Commission.
