8.4 Communications for Control System Monitoring and Input
8.4.1 RF Communications systems that are required to exercise the required Level of Control (as outlined in Chapter
2), or are necessary to enable the Emergency Stop functionality, should be provided with reversionary modes
and backup energy supplies, the scope of which will depend on both the MASS Category (see Chapter 3) and
the Area of Operation.
8.4.2 These reversionary modes and energy supplies should be considered in the Risk Assessment, such that the risk
of loss of control communications and ability to execute the emergency stop function is reduced to a level As Low
As Reasonably Practical (ALARP).
8.4.3 The communication suite is assumed to reflect the holistic coding requirements or registration certification of the
vessel. Any reduction in system fit should be formally recorded, with each new mission/task requirement being
reviewed and documented as ‘fit for task’ prior to operation.
8.4.4 If alternative communication systems are adopted as the primary method, the appropriate minimum level of RF
communication capability should be fitted relative to the specific operation cycle.
8.4.5 In the case of a wider system failure, an adequate failsafe communication system to support COLREG compliance
should be fitted. This system should have suitable range and endurance capabilities as to enable the operator
to effect appropriate safe management of the uncontrolled vessel.
