KUP 63 Have knowledge of personal survival techniques

The vast and often unpredictable nature of the world’s oceans presents unique challenges to maritime safety. Personal survival techniques are not just skills to be learned; they are vital tools that can mean the difference between life and death in emergency situations at sea. This lesson will provide an in-depth exploration of the knowledge and practical skills essential for survival in maritime emergencies.

The importance of these techniques cannot be overstated. In 2019 alone, the International Maritime Organization reported 3,174 lives lost at sea. Many of these tragedies might have been prevented with proper knowledge and application of survival techniques. As we delve into this crucial topic, remember that your most powerful survival tool is your mind – your will to live and your ability to think clearly under pressure.

I. Understanding Maritime Emergencies

Maritime emergencies can arise from various situations, each presenting unique challenges for survival. Let’s explore some of the most common scenarios:

A. Fire:
Shipboard fires are one of the most dangerous emergencies at sea. In 2018, the car carrier Sincerity Ace experienced a major fire in the Pacific Ocean. The crew of 21 had to abandon ship, with 16 being rescued successfully. This incident highlights the critical importance of fire prevention and evacuation procedures.

Fires can spread rapidly on ships due to the presence of flammable materials and confined spaces. They can lead to structural damage, loss of power, and the release of toxic fumes. In a fire situation, knowledge of evacuation routes, the location and use of firefighting equipment, and proper abandonment procedures are crucial.

B. Collision:
Collisions at sea, while relatively rare, can be catastrophic. The collision between the USS Fitzgerald and the MV ACX Crystal in 2017 resulted in seven fatalities and significant damage to both vessels. This incident underscores the importance of immediate damage assessment and evacuation readiness.

In a collision scenario, rapid flooding can occur, necessitating quick decision-making regarding whether to abandon ship or attempt to save the vessel. Understanding damage control procedures and being prepared for quick evacuation are key survival skills.

C. Flooding:
Flooding can result from collisions, groundings, or failure of the ship’s hull integrity. The sinking of the MV Sewol in 2014, which resulted in 304 fatalities, many of them students, illustrates the devastating potential of rapid flooding.

In flooding situations, knowledge of watertight compartments, emergency pumps, and abandon ship procedures is critical. Understanding how your vessel behaves when taking on water can inform crucial decisions about when to abandon ship.

D. Severe Weather:
Extreme weather conditions pose significant risks to vessels of all sizes. The El Faro tragedy in 2015, where all 33 crew members were lost when the ship sailed into Hurricane Joaquin, serves as a stark reminder of the power of nature at sea.

Survival in severe weather scenarios often depends on the integrity of the vessel and the crew’s ability to navigate and maintain stability. However, if abandonment becomes necessary, survival craft must be able to withstand extreme conditions.

E. Piracy:
While not a natural disaster, piracy remains a significant threat in certain parts of the world. The hijacking of the Maersk Alabama in 2009 off the coast of Somalia brought modern piracy into the global spotlight.

In piracy situations, survival may depend on a combination of security measures, compliance with established protocols, and potentially, negotiation skills. While beyond the scope of traditional survival techniques, awareness of piracy risks and response procedures is important for maritime professionals.

II. Psychological Aspects of Survival

The will to survive is perhaps the most crucial factor in any survival situation. The story of Poon Lim, who survived 133 days alone on a raft in the Atlantic during World War II, is a testament to the power of mental resilience.

A. Recognizing and Managing Fear and Panic:
Fear is a natural response to life-threatening situations, but uncontrolled fear can lead to panic, which impairs decision-making and reduces chances of survival. Techniques for managing fear include:

  1. Controlled breathing: Practice deep, slow breaths to calm your nervous system.
  2. Positive self-talk: Remind yourself of your training and your will to survive.
  3. Focus on immediate tasks: Concentrate on what needs to be done right now, rather than dwelling on the overall situation.

B. Importance of Positive Mental Attitude:
Maintaining a positive outlook can significantly impact survival chances. Strategies include:

  1. Setting small, achievable goals
  2. Visualizing rescue and reunion with loved ones
  3. Maintaining a routine, even in survival situations
  4. Drawing strength from religious or personal beliefs

C. Decision Making Under Stress:
Survival situations require clear thinking and decisive action. The STOP acronym can be helpful:

  • Stop: Pause and assess the situation
  • Think: Consider your options and resources
  • Observe: Look around for potential dangers and assets
  • Plan: Decide on a course of action and implement it

Remember, your mental state can influence others in a group survival situation. Demonstrating calm and purposeful behavior can help maintain morale and increase collective chances of survival.

III. Abandon Ship Procedures

Knowing when and how to abandon ship is a critical survival skill. The tragic sinking of the Costa Concordia in 2012, which resulted in 32 fatalities, underscores the importance of clear abandon ship procedures and passenger preparedness.

A. Abandon Ship Signals:
Recognizing the abandon ship signal is crucial. The international maritime abandon ship signal is seven short blasts followed by one long blast on the ship’s whistle, accompanied by a similar signal on the general alarm system.

It’s important to note that in some emergencies, there may not be time for a formal abandon ship signal. Therefore, crew members should be prepared to recognize signs of imminent danger and act accordingly.

B. Muster Stations:
Every crew member and passenger must know their assigned muster station. This information is typically provided during safety briefings and is posted on safety cards in passenger cabins or crew areas.

The muster list, also known as a station bill, outlines each crew member’s duties during an emergency. Familiarize yourself with this document and understand your role in abandon ship procedures.

C. Abandonment Sequence:

  1. Don lifejacket correctly: Ensure it’s securely fastened and adjust for a snug fit.
  2. Collect additional warm clothing if time permits: Hypothermia is a significant risk in water survival situations.
  3. Muster at designated station: Move quickly but calmly to avoid creating panic.
  4. Follow instructions from officers and crew: Clear communication and adherence to the chain of command are crucial in emergencies.
  5. Board survival craft or jump into water as directed: If jumping into water becomes necessary, use the proper technique to minimize injury and cold shock.

D. Practical Considerations:

  • If possible, send a distress call before abandoning ship.
  • Take emergency supplies if readily available (water, food, additional signaling devices).
  • Assist others who may be struggling with the evacuation process.
  • If time permits, ensure all spaces are checked for trapped or unconscious individuals.

Remember, the decision to abandon ship is typically made by the captain. However, in extreme circumstances where the command structure has broken down, individuals may need to make this decision based on their assessment of the situation.

IV. Survival in Water

Survival in water presents unique challenges, including the risks of drowning, hypothermia, and exhaustion. Understanding these risks and knowing how to mitigate them is crucial.

A. Cold Shock Response:
Sudden immersion in cold water can cause an immediate gasp reflex, potentially leading to water inhalation. The initial minute after immersion is critical. Techniques to manage cold shock include:

  1. Try to enter the water gradually if possible.
  2. If you must jump, hold your nose and cover your mouth.
  3. Once in the water, focus on controlling your breathing. Take slow, deep breaths.
  4. Keep your head above water. A properly donned lifejacket will assist with this.

B. Swimming Techniques:
Conservation of energy is crucial for prolonged survival in water.

  1. Heat Escape Lessening Posture (HELP):
  • Cross your arms tightly against your chest.
  • Draw your knees up to your chest, keeping your legs together.
  • Float as still as possible to conserve heat and energy.
  1. Huddling Technique:
    In groups, form a circle facing inward:
  • Link arms over each other’s shoulders.
  • Press your sides together.
  • Intertwine your legs in the center of the circle.
    This position helps conserve heat and keeps the group together.
  1. Treading Water:
    When treading water is necessary:
  • Use slow, deliberate movements.
  • Keep your head above water, tilted slightly back.
  • Use your arms for gentle sculling motions.
  • Move your legs in a slow, scissor-like motion or a gentle eggbeater motion.

C. Hypothermia:
Hypothermia is a significant risk in water survival situations. Understanding its progression and how to delay its onset is crucial.

Symptoms of hypothermia progress as follows:

  1. Shivering and cold sensation
  2. Slow, weak pulse
  3. Slurred speech
  4. Confusion and irrational behavior
  5. Unconsciousness

To delay the onset of hypothermia:

  • Keep your head and neck out of the water.
  • Assume the HELP or huddle position.
  • Stay as still as possible to conserve energy.
  • If wearing an immersion suit, ensure it’s properly sealed.

Treatment of hypothermia victims:

  • Move the person to a warm environment if possible.
  • Remove wet clothing and dry the person.
  • Warm the body gradually, starting with the trunk.
  • If conscious, give warm, sweet drinks (no alcohol).
  • Seek medical attention as soon as possible.

D. Threats in Water:

  1. Marine Life:
    While shark attacks are rare, they are a concern in some waters. To minimize risk:
  • Stay in groups.
  • Avoid areas known for shark activity.
  • Remove shiny objects that might resemble fish scales.
  • If a shark is spotted, maintain a defensive posture and prepare to fight if attacked. Jellyfish stings can be painful and potentially dangerous. If stung:
  • Remove any remaining tentacles carefully.
  • Rinse the affected area with seawater (not fresh water).
  • Apply vinegar if available to neutralize the sting.
  1. Dehydration and Saltwater Consumption:
    Never drink seawater. It increases dehydration and can lead to kidney failure. To manage thirst:
  • Moisten lips with seawater but do not swallow.
  • If it rains, collect and drink as much freshwater as possible.
  • Once in a survival craft, carefully ration any available water.
  1. Fatigue and Exhaustion:
    Conserve energy whenever possible:
  • Float rather than swim if not making progress towards rescue or land.
  • Take turns resting if in a group.
  • Stay positive and focus on survival goals to combat mental fatigue.
