Issued 31 January 2023
Resolved
On 30Jan2023, it was discovered that the Cargo Ship Safety Radio Certificate (CSSRC) expired 10Dec2022. Upon review of SMS Document ID 6873 (Rev 3), paragraph 4 of the “Vessel Documents and Certificates – General” section indicates both the master and Program Manager will ensure inspections and surveys are completed as required. Section 1(a) states, “Where the document originates on the vessel, the Master will update the document dates in DMS.” The master is unable to update certificate records in the “Document Management System” (NS5 where SMS is located). The master follows the process identified in Section 2(a) “Program Manager or Marine Safety and Standards (MSS) Department Responsibilities” by emailing documents to MSS for entry into DMS.
It was noted during USCG attendance many moving parts may have contributed to the lapse of the CSSRC: upcoming maintenance period, authorization from FCC for ABS to issue CSSRC, vessel’s upcoming name change, and company's change of address.
