On October 13, 2003, at approximately 1435 (local), the M/V NCC JIZAN was preparing to receive the Savannah Bar Pilot in Tybee Roads for an inbound transit, when the propulsion failed to start during required engine tests. The pilot departed the vessel after it anchored. The vessel was later allowed to enter port under a two-tug escort per a COTP order. According to the chief engineer's statement, the ahead/astern test failed when the start air valve remained opened and drained the start air from the tanks. The engineers opened, cleaned and lubricated control valves; and checked signals in way of the starting circuit. The engineers found a pneumatic control air valve sticking. This valve, when stuck open, sends a signal to the main start air valve on the main engine to remain open. After cleaning and lubrication, the engineers retested ahead and astern starts starts finding all satisfactory. The vessel entered port and was boarded by the undersigned and the CID. Examined the same control air valves and two more, noting no anomalies. Concurred with the chief engineers diagnosis. Rescinded the COTP order. The CE could not produce any documentation either in technical manuals or the Safety Management System (SMS) on maintenance frequency or requirements for the control air valves. Recommended the CE make note of the discrepancy in the ship's SMS and ensure proper maintenance of the control air system. A copy of the report indicating same is enclosed in the case file. Case closed. /S/ SIO, SAVMS
