The RMS Titanic disaster seen in the light of risk and safety theories and models

Introduction

• The Titanic disaster remains a significant event in public consciousness, with extensive media coverage and cultural impact.
• The paper analyzes the Titanic accident using various risk and safety theories to explore whether such an accident could happen today and if it could have been foreseen.

Risk and Safety Theories

• Event/Condition Analysis and Defence in Depth (Swiss Cheese Model)

  • Accidents result from a combination of latent and active errors.
  • The Titanic’s perceived invincibility led to less cautious navigation and inadequate training.

• Domino Theory

  • Accidents are part of a sequence of events; removing one factor can prevent the accident.
  • Factors in the Titanic accident included competitive pressures, ignorance of safe practices, and unsafe speed.

• Iceberg Theory (Accident Distribution Ratio)

  • Serious accidents are preceded by numerous warnings and near misses.
  • The Titanic had several near accidents and ice warnings before the disaster.

• High Reliability Theory (HRO) and Normal Accident Theory (NAT)

  • HRO: Complex systems can be managed safely with proper design and management.
  • NAT: Accidents are inevitable in complex, tightly coupled systems.
  • The Titanic’s design and management had both strengths and weaknesses in terms of safety.

• Multi-Level Model

  • Risk management involves all levels of society, from government to individual operators.
  • Rapid changes in the shipping industry outpaced regulatory and management adaptations.

• Migration Towards the Boundary

  • Human behaviour tends to push towards the limits of acceptable performance.
  • The Titanic’s management and market pressures led to risky behaviour.

• Risk Homeostasis

  • People adjust their behaviour to maintain a constant level of perceived risk.
  • The Titanic’s advanced safety features may have led to complacency and risky decisions.

Discussions and Conclusions

• The Titanic accident could happen today due to similar organizational and systemic issues.
• While latent errors were present, foresight is limited, and accidents often result from complex coincidences.
• The Titanic disaster led to significant safety improvements, such as the SOLAS convention and the International Ice Patrol.

Closing Remarks

• Historical inquiries into the Titanic focused on legal blame rather than understanding human and organizational factors.
• Modern accident investigations aim to prevent future incidents rather than assign blame.
