• Principle: PSC inspects foreign ships in port to verify compliance with international conventions; two levels: documentary control and clear-grounds detailed inspection
• Legal basis: SOLAS I/19, SOLAS XI-1/4, MARPOL Annex I reg 11, ICLL article 21, STCW article X and A-I/4; harmonised procedure A.1052(27)
• Emergency generator: SOLAS II-1/42; verify valid certificate, automatic start upon main power failure, connection to emergency switchboard within 45 s, protection of stored energy, weekly/monthly test records
• Auxiliary steering gear: SOLAS II-1/29; verify valid certificate, operation from bridge, rudder 15°–15° in ≤60 s, power supply, alarms
• Lifeboat engine: verify valid certificate, weekly/monthly test records, fuel availability, starting and operation
• Bilge pump: verify valid certificate, operation, capacity, alarms, system integrity
• SOPEP: MARPOL Annex I regulation 37; verify approved plan on board, list of authorities/persons to contact, crew familiarity, oil spill equipment
• ETO role: ensure electrical systems and records are maintained; support PSC preparation and correct electrical deficiencies
