• Principle: PSC inspects foreign ships in port to verify compliance with international conventions; valid certificates accepted unless clear grounds exist for detailed inspection
• Levels: documentary control first; clear-grounds trigger for operational/detailed inspection
• Emergency generator: SOLAS II-1/43, 44; verify location above uppermost continuous deck and outside machinery casing, self-contained, independent fuel supply, automatic energizing, documented periodic tests under load, guards, lagging, no leaks, adequate voltage/frequency, ground detection, two independent starting sources, engineering log records
• Bilge pump: SOLAS II-1/21; verify at least two bilge pumps, operational condition, engineering log records
• Auxiliary steering gear: verify certificate, operational test, power supply, rudder angle indicators, communication, test records
• Lifeboat engine: verify certificate, start tests, fuel system, cooling, coupling, sea trial records, crew familiarity
• SOPEP: MARPOL Annex I regulation 11; verify approval, availability, crew familiarity, drills
• Governing instruments: SOLAS I/19, XI-1/4; MARPOL Annex I reg 11; IMO Resolutions A.1052(27), A.1138(31); MEPC.201(62) reg-9, MEPC.203(62) reg-10, MEPC.117(52) reg-11
• ETO role: verify electrical aspects of emergency generator and steering gear controls; ensure documentation and test records are complete
