What happens to a human body when a submarine implodes?
A submarine implosion occurs when the pressure of the surrounding water becomes too great for the vessel’s hull to withstand, resulting in a catastrophic collapse of the ship’s structure. In this article, we’ll delve into the devastating effects an implosion has on a human body, considering various factors such as external pressures, internal damage, and the subsequent consequences on human physiology.
Why Submarines are Prone to Implosion

Design and Functioning of Submarines
Before understanding the effects of implosion on the human body, it’s essential to grasp the design and functionality of submarines. Submarines are designed to withstand crushing pressures at great depths. They have thick hulls made of strong metals like steel or titanium to withstand the pressure of water.
Types of Pressures
There are three main types of pressures affecting submarines:
- Ambient Pressure: The surrounding water pressure at a particular depth.
- Pressure Due to Depth: As you descend, the water pressure increases exponentially.
- Internal Pressure: The air pressure inside the submarine’s hull.
Causes of Implosion
When a submarine implodes, it’s usually due to a combination of factors such as:
- Damage: Cracks or ruptures in the hull from an accident, collision, or combat.
- Deterioration: Hull corrosion or fatigue.
- Design Flaw: Inadequate safety margin in the hull’s strength-to-weight ratio.
Effects on the Human Body
When a submarine implodes, the immediate consequences for the human body are catastrophic. Here are some of the effects that can occur:
- Shockwave: The collapse of the hull creates an explosive shockwave that radiates outward, causing the crew to experience a devastating blow, akin to being hit by a massive hammer.
- Decompression Sickness: The sudden collapse of the hull creates uneven pressure changes that can cause rapid gas expansion within the body, leading to gas bubbles forming in the blood vessels and tissues. This is known as decompression sickness or "the bends".
- Intra-cranial Hemorrhaging: The shockwave and subsequent pressure changes can cause bleeding within the brain, resulting in severe headache, confusion, and eventual death.
- Eardrum Damage: The intense pressure changes can rupture the eardrum and cause permanent hearing loss.
- Air Embolism: Gas bubbles created during the implosion can lodge in the bloodstream and block blood flow to vital organs, leading to incomplete oxygenation and damage.
Timetable of Events
During an implosion, several devastating events unfold in quick succession:
| Time Frame | Event |
|---|---|
| 1-2 seconds: Implosion occurs, crew exposed to shockwave | |
| 2-4 seconds: Decompression sickness and intra-cranial hemorrhaging begin | |
| 4-6 seconds: Eardrum damage and air embolism can occur | |
| 10-15 seconds: Crew succumb to injuries and die or enter a coma |
Consequences and Challenges in Rescue and Recovery
If a submarine implodes and the crew is extracted alive, they face immense physical and psychological challenges. Some of the consequences they may experience include:
- Long-term Health Complications: Decompression sickness and other injuries can cause ongoing health issues, requiring lifelong treatment.
- PTSD and Trauma: Survivors may experience intense psychological trauma, exacerbated by the catastrophic nature of the event.
- Medical Challenges: Rescuing and treating survivors from such an event is incredibly complex due to the severity of the injuries and the lack of medical resources at such extreme depths.
Prevention and Mitigation Measures
To minimize the risks associated with submarine implosions, designers and builders are implementing various measures:
- Improved Hull Strength and Design: Enhancing hull strength and incorporating stronger, lighter materials.
- Regular Maintenance and Inspection: Conducting regular checks for damage, corrosion, or fatigue.
- Submarine Operations and Planning: Implementing strict guidelines and protocols for safe submersible operations.
Conclusion
In conclusion, an implosion of a submarine is a catastrophic event with devastating consequences for human physiology. The effects can include shockwave, decompression sickness, intra-cranial hemorrhaging, and air embolism. Understanding the causes of implosion and the timeline of events can help authorities, designers, and researchers better prepare for and mitigate these risks.
