Casualty Control

• Casualty control is the positive action taken to correct, control, and/or combat operational discrepancies experienced during underway operations.

7

Casualty Control

• An actual emergency is not the time to learn emergency procedures.

• Frequent underway casualty control drills both prepare and improve ones response.

• After getting underway, closely observe the engine gauges.

Fire in the Engine Room

The fixed Halon 1301 Fire Extinguishing System has the capacity to extinguish an engine room fire provided the instructions for its use are followed carefully.

10

Loss of Steering• If the helm turns freely without

effect on rudders. • Loss of steering (Cable/Hydraulics)”

• If the helm will not turn. • “Loss of steering (Jammed

rudder)”

13

Loss of Steering (Hydraulic)a. Bring both engines to neutral or

clutch ahead to maintain minimum steerage.

b. Notify crew of causality.c. Steer with engines, only to maintain

steerageway.d. Engineer to investigate cause of the

casualty. e. If so directed by the coxswain, crew

member to rig the anchor.

14

Loss of Steering (Hydraulic)

f. Crew member to provide the emergency tiller from the lazarette.

g. Place both engines in neutral. h. When directed by coxswain,

carefully mount the emergency tiller on the port rudder post.

i. Gain positive control of the rudders using the emergency tiller.

15

Loss of Steering (Hydraulic)

j. Detach release pin on Stbd. rudder post to disconnect steering hydraulic ram. Tie steering hydraulic ram end out of the way.

k. Test rudders for complete range of motion (full port to full Stbd.).

l. Place tiller arm in the amidships position. m. Engage the engines one at a time. This

reduces the propeller thrust on the rudder blades and tiller.

16

Loss of Steering (Hydraulic)

n. Keep engine RPM’s to a minimum to reduce strain on the crewmember tending the emergency tiller. Do not exceed 1000 engine RPM.

o. Standard steering commands shall be given to the crewmember tending the tiller.

p. Inform station of situation.

17

Jammed Rudder

a. Bring both engines to neutral or clutch ahead position to maintain minimum steerage.

b. Notified crew of casualty. c. Steer with engines, only to maintain

bare steerageway. d. Engineer to investigate the casualty. e. If so directed by the coxswain, crew

member to rig the anchor.

18

Jammed Rudder

f. Crew member to provide the emergency tiller from lazarette.

g. Place both engines in neutral. h. When directed by coxswain,

carefully mount the emergency tiller on the port rudder post.

i. Detach release pin on Stbd. rudder post to disconnect steering hydraulic ram. Tie steering hydraulic ram end out of the way.

19

Jammed Rudder

j. To determine the next step, turn the helm;

IF The Helm

THEN:

Turns Proceed to step “p”.

Does not turn

Proceed to step “k”.

20

Jammed Rudderk. Reinstall the steering hydraulic ram

release pin. l. Engineer, remove the tie bar rod

between port and starboard rudder post.

m. Exercise rudders to determine which rudder is jammed.

n. Attempt to free jammed rudder with the tiller.

21

Jammed Ruddero. If unable to free jammed rudder,

secure rudder to prevent movement. IF: THEN: STEER

The port rudder is jammed

Lash the emergency tiller arm with mooring lines to the stern cleats.

With the Helm.

The starboard rudder is jammed

Keep the hydraulic ram attached.

With the Emergency tiller.

22

Jammed Rudder

p. Place the rudder and emergency tiller amidships.

q. Engage engines one at a time. This reduces the propeller thrust on the rudder and emergency tiller.

r. Keep engine RPM’s to a minimum to reduce strain on the crewmember tending the tiller.

23

Jammed Rudder

s. Standard steering commands shall be given to the crewmember tending the tiller.

t. Kept station informed of situation.

24

Collision with a Submerged Object/ Running Aground

Collision with a submerged object or accidentally running aground can cause major underwater damage to the boat, including;

• Damage to shafts, propellers, struts, and/or rudders.

• Putting a hole in the hull.

25

Collision with a Submerged Object/ Running Aground

1. Reduce RPM’s on both engines and place in neutral

2. Notified crew of casualty. 3. Check for injuries. 4. Verify position. 5. Engineer, check the engine room

for flooding, and damage.

26

Collision with a Submerged Object/ Running Aground

6. Crew member, Check all other compartments for flooding.

7. Engage engines separately, at various speeds to check for vibrations.

8. Kept station informed of situation.

27

Reduction Gear Failure

• The reduction gear changes the shaft and propeller rotation from forward, neutral and reverse. If the reduction gear fails, the boat may not move.

28

Reduction Gear FailureA reduction gear failure is indicated if the

reduction gear; • Fails to engage in forward or reverse.• Fails to disengage when placed in

neutral. • Disengages on its own when clutched

in. • Produces excessive noise. • Has Smoke coming from it.

29

Reduction Gear Failure

1. Place engine in the neutral position.

2. Notified crew of casualty. 3. Have engineer investigate the

casualty. 4. Kept station informed of situation.

30

High Water Temperature

• The engine’s jacket water maintains the engine temperature; if the temperature is to high, severe damage could occur to the engine.

• If the main engine jacket water coolant reaches 205° F, the alarm bell and amber indicator light will activate.

31

High Water Temperature1. Reduce engine RPM’s to clutch

ahead on both engines. 2. Identify the affected engine. 3. Notify the crew of casualty. 4. If temperature continues to rise,

secure the affected engine.5. Check overboard discharge.6. Engineer: to check engine room

through the lower cabin view port

32

High Water Temperature

7. If so directed by the coxswain, crew member: to rig the anchor.

8. Engineer; to enter the engine room. Crew member; to act as safety observer for the engineer.

9. Kept station informed of situation.

33

Loss of Lube Oil Pressure

• Lube oil pressure and flow within an engine is vital to all moving parts within the engine.

• If lube oil pressure fails, severe damage could occur to the engine.

• If the lube oil pressure falls below set point a switch will activate, the alarm bell and red indicator light.

34

Loss of Lube Oil Pressure

1. Reduce engine RPM’s to clutch ahead on both engines.

2. Identify the affected engine. 3. Notify the crew of casualty. 4. Secure affected engine. 5. Engineer to check engine room

through the lower cabin view port to assess the situation.

35

Loss of Lube Oil Pressure

6. If so directed by the coxswain, crew member to rig the anchor.

7. Engineer; to enter the engine room. Crew member; to act as safety observer for engineer.

8. Ensure fire extinguishers are on scene.

9. Kept station informed of situation.

36

Engine Will Not Start

• An emergency is not the time to have your engines not start.

• Properly complete pre-start and start procedures.

• Properly conduct daily check offs.

37

Review

• Many drills start out with the same or similar initial responses. Such as:

Secure engines or Bring engines to the neutral

position.Sound the alarm. Note position.

38

Review

• What equipment will or might be broken out.

• Always keep safety in mind, stop any unsafe conditions, secure the drill if necessary.

• Drills should be practiced, so the response will be automatic and efficiently completed.
