Integrated approach to reducing ship vulnerability

Reducing the vulnerability of ships to the greatest extent possible requires an integrated approach. This comprises design methods, security/safety measures, the automated deployment of systems, emergency response resources, human action, intelligent advisory systems and the interactions these elements involve.TNO has a wealth of expertise in these fields and contributes to the development of the necessary technologies, sub and otherwise.

In order to visualise how a calamity on a ship unfolds in the wake of an incident use is often made of a ‘bathtub curve’. Six damage-reducing and/or damage-stopping steps can be identified over time:

  • Passive vulnerability reduction by means of prior measures (in the ship’s design);
  • Automated restoration of systems;
  • Escalation reduction by means of prior measures (in the ship’s design);
  • Automated escalation reduction;
  • Escalation reduction by means of human action;
  • Restoration of functionality by means of human action.

These six steps form a coherent, interactive whole that, following an incident, ensures that the ship’s operational readiness is restored as quickly as possible to as high a level as possible. The people, resources, methods and measures included in these six steps must be fully incorporated in the process of designing a new ship in order that the ship’s ability to sustain damage is maximised. TNO is developing the full set of complex ship vulnerability analysis tools this requires, and is contributing to the development of the necessary supporting sub-technologies, systems and procedures.
