Consultation—Marine order 27—Safety of navigation and radio equipment

We consulted you about safety of navigation and radio equipment.

The consultation closed Wednesday 2 October 2019.

Marine order 27 provides information about the following:

  • radio equipment and communications
  • navigation safety measures and equipment
  • danger, urgency and distress signals and messages.

Key changes

The proposed new Marine order 27 (Safety of navigation and radio equipment) will amend the existing marine order to allow other approved operators to provide mobile satellite services within the Global Maritime Distress and Safety System (GMDSS).

Proposed changes include:

  • Replacing references to Inmarsat, where practical, with ‘recognised mobile satellite service’. This change gives effect to IMO resolution MSC.436(99).
  • Schedule 2 will include amending IMO resolutions.
  • Minor corrections to GMDSS frequencies at Schedule 4.


It is proposed that this amended order will come into effect on 1 January 2020.
