Radars , radios and lights on ship's gantry mastSOLAS V Regulation 16-Maintenance of equipment.

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.

ISM and maintenance

ISM paragraph 5.10 contains the codes requirements for maintenance.

“5.10 Maintenance of the Ship and Equipment

5.10.1 The Company should establish procedures to ensure that the ship is maintained in conformity with the provisions of the relevant rules and regulations and with any additional requirements which may be established by the Company.

Time to go backwards in this series of posts to fill a gap. The exploration of environmental related certificates will be put on pause whilst the ISM certificates are covered, certificates that should have appeared within the managing ship section of the blog.

The ISM code’s full name is ‘The International Management Code for the Safe Operation of Ships and for Pollution Prevention‘. The ISM Code provides an international standard for the safe management and operation of ships and for pollution prevention.

Why are the certificates required?

The requirement for these certificates arise from  SOLAS Chapter IX, Management for the Safe Operation of Ships’.

Document of Compliance (DOC)

The  “Document of Compliance” (DOC) is issued to a Company which complies with the requirements of the ISM Code following  verification of compliance with the requirements of the ISM Code.

How long is the DOC valid?
The DOC is valid for a period of five years and subject to annual verification within three months before or after the anniversary date to confirm the effective functioning of the SMS.

SMC should be issued to a ship following an initial verification of compliance with the requirements of the ISM Code. The SMC is valid for a period of five years.

The validity of the SMC is subject to at least one intermediate verification, confirming the effective functioning of the SMS, and that any modifications carried out since the previous verification comply with the requirements of the ISM Code.

A Really Handy Guide to the ISM Code-A new revision aid for Kindle


I have just published the next book in the Really Handy Range. This one is a move a way from the looking out of the bridge windows towards wider shipboard operations.

The ISM code is deceptive; as a piece of international shipping legislation it appears small and vague, and yet, it has huge power to determine how ships are operated. Its relatively few words influence every aspect of vessel operations, both afloat and ashore. Sitting at the centre ofship’s safety, ISM  links all maritime safety laws, guidance and procedures together.


A good understanding of the ISM code is therefore required by all personnel involved in ship operations, and this book will assist in achieving that understanding. This Really Handy Book is aimed primarily at those studying for Officer of the Watch, Chief Mate’s, Second Engineer’s, Master’s, and Chief Engineer’s qualifications. It will also be of use as a reference source or refresher for qualified personnel. It is not a legal textbook though, so for legal advice refer to the source documents, or appropriate books. This Really Handy Book contains a description of the code, a revision aid.

If you download the new book I recommend following this blog. Over the next few posts I will be exploring a wide range of topics with connections to the code. However, I cannot promise that I will resist the temptation to entirely stay clear of my favourite topic-the collision regulations.
