Which statement is accurate regarding maintenance requirements for A3 ships under GMDSS?

The accurate statement regarding maintenance requirements for A3 ships under the GMDSS is that redundancy of functions and on-board maintenance can partially meet the requirement. In the context of GMDSS (Global Maritime Distress and Safety System), A3 ships are required to maintain communication capabilities for safety purposes while at sea. Having redundant systems ensures there is a backup if the primary system fails, which is crucial for maintaining operational readiness.

On-board maintenance by a qualified GMDSS Maintainer is essential, but it is not sufficient by itself to fully meet all the regulatory standards. This is where the concept of redundancy comes into play; having multiple systems or components performing the same function increases reliability but does not replace the need for proper maintenance procedures to be followed.

While shoreside maintenance is a valuable component of the overall maintenance strategy, it cannot be relied upon solely for A3 ships because operational readiness must be assured while at sea. Thus, the combination of on-board maintenance and redundancy addresses the regulation requirements more comprehensively.
