Procedures for high water temp?
Clutch ahead Identify casualty and notify crew Check bilges Feel RW pipes Check RW suction valves Check and shift strainers Check de-icing valves Check RW pump Check JW pump Check JW level Check LO
Procedures for loss of steering electrical
Bring throttles to neutral
Reacts ate jog lever
Shift to hydraulic helm
Check all stations
Procedures for loss of steering hydraulic.
Bring throttle to neutral Secure engines Verify safe to enter engine room Check bilge Check fluid level Check entire system
Procedures for fire in the engine room
Bring throttles to neutral Check engine room through port hole If a fire I present: Secure engines Secure fuel Secure air dampeners Energize CO2 Request bypass 30 second delay Secure electrical Set fire watch
Procedures for grounding/collision with a submerged object.
Bring throttles to neutral
