• Location: above the uppermost continuous deck, readily accessible from the open deck, not forward of the collision bulkhead
• Starting: independent means; automatic on loss of main power; battery for small sets, compressed air for larger sets; connect to emergency switchboard automatically; within 45 s
• Fuel: independent supply; flashpoint not less than 43°C
• Cooling: independent freshwater system with heat exchanger, or keel cooling; designed to function at list up to 22.5° and trim up to 10°
• Periodic attention: full-load and starting-time tests under simulated blackout; routine on-load tests
• Governing instrument: SOLAS Chapter II-1 Regulation 42; IMO Res. A.1023(26) ch-5 §5.4.8
