  required basic engineering casualty control
  exercises, in accordance with, 41 UTB Operators
  Manual, M16114.2 (Series).

  engine lube oil pressure.
• 8.9.8 Take corrective actions for engine will
  not start.

6
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.

  rudders.
• Loss of steering (Cable/Hydraulics)

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

Loss of Steering (Hydraulic)

1. Bring both engines to neutral or clutch ahead to
   maintain minimum steerage.
2. Notify crew of causality.
3. Steer with engines, only to maintain steerageway.
4. Engineer to investigate cause of the casualty.
5. If so directed by the coxswain, crew member to
   rig the anchor.

14
Loss of Steering (Hydraulic)

1. Crew member to provide the emergency tiller from
   the lazarette.
2. Place both engines in neutral.
3. When directed by coxswain, carefully mount the
   emergency tiller on the port rudder post.
4. Gain positive control of the rudders using the
   emergency tiller.

15
Loss of Steering (Hydraulic)

1. Detach release pin on Stbd. rudder post to
   disconnect steering hydraulic ram. Tie steering
   hydraulic ram end out of the way.
2. Test rudders for complete range of motion (full
   port to full Stbd.).
3. Place tiller arm in the amidships position.
4. Engage the engines one at a time. This reduces
   the propeller thrust on the rudder blades and
   tiller.

16
Loss of Steering (Hydraulic)

1. Keep engine RPMs to a minimum to reduce strain
   on the crewmember tending the emergency tiller.
   Do not exceed 1000 engine RPM.
2. Standard steering commands shall be given to the
   crewmember tending the tiller.
3. Inform station of situation.

17
Jammed Rudder

1. Bring both engines to neutral or clutch ahead
   position to maintain minimum steerage.
2. Notified crew of casualty.
3. Steer with engines, only to maintain bare
   steerageway.
4. Engineer to investigate the casualty.
5. If so directed by the coxswain, crew member to
   rig the anchor.

18
Jammed Rudder

1. Crew member to provide the emergency tiller from
   lazarette.
2. Place both engines in neutral.
3. When directed by coxswain, carefully mount the
   emergency tiller on the port rudder post.
4. Detach release pin on Stbd. rudder post to
   disconnect steering hydraulic ram. Tie steering
   hydraulic ram end out of the way.

19
Jammed Rudder

1. To determine the next step, turn the helm

20
Jammed Rudder

1. Reinstall the steering hydraulic ram release pin.
   
2. Engineer, remove the tie bar rod between port and
   starboard rudder post.
3. Exercise rudders to determine which rudder is
   jammed.
4. Attempt to free jammed rudder with the tiller.

21
Jammed Rudder

1. If unable to free jammed rudder, secure rudder to
   prevent movement.

22
Jammed Rudder

1. Place the rudder and emergency tiller amidships.
2. Engage engines one at a time. This reduces the
   propeller thrust on the rudder and emergency
   tiller.
3. Keep engine RPMs to a minimum to reduce strain
   on the crewmember tending the tiller.

23
Jammed Rudder

1. Standard steering commands shall be given to the
   crewmember tending the tiller.
2. 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 RPMs 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

1. Crew member, Check all other compartments for
   flooding.
2. Engage engines separately, at various speeds to
   check for vibrations.
3. 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 Failure

• A 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 engines 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 Temperature

1. Reduce engine RPMs 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

1. If so directed by the coxswain, crew member to
   rig the anchor.
2. Engineer to enter the engine room. Crew member
   to act as safety observer for the engineer.
3. 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 RPMs 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

• If so directed by the coxswain, crew member to
  rig the anchor.
• Engineer to enter the engine room. Crew member
  to act as safety observer for engineer.
• Ensure fire extinguishers are on scene.
• 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.
