Some simple demonstrations of the capabilities of the IRM software are provided below.  More detailed and complex demonstrations can be arranged by completing the “Contact Us” form on the Contact/Downloads page of this website.

Integrated Recoverability Model™ (IRM)


Simulation Demos

Video Notes - These files have been sped up and are not being played in real time.   

Crew Movement example
In the following example, a fluid system is ruptured.  The portion of the system connected to the rupture turns red.  The rest of the system, not connected to the damage, appears blue.  Three valves need to be closed to isolate the rupture.  After a delay to represent the time it takes to obtain situational awareness of the rupture, three crewmembers with the required skillset are identified by the Simulator and assigned to close the valves.  All three start in the same compartment and head toward the door.  The first crewmember opens the door, all three go through, and the last crewmember closes the door.  Once all three valves are closed, the rupture is isolated and the other half of the fluid system turns blue to indicate that it is no longer connected to damage.  The isolated segment remains red.  All three crewmembers return to their starting locations.

Pipe Rupture Isolation example

In the example below, a generator has a primary and alternate source of fuel.  The primary supply becomes ruptured and the generator automatically switches to its alternate supply (a small gravity tank).  A crewmember must isolate the rupture by closing the downstream valve.  Although not explicitly shown in the video, the generator pulls fuel from the gravity tank and the level of fuel in the tank is tracked.  Once the rupture is isolated, the generator continues to draw fuel from the gravity tank, but the gravity tank is able to be refilled from the larger tank and the fluid level rises.  The end user never loses power in this example.

Seawater Pump Damage and Repair example

In the subsequent example, the seawater pump supplying the lube oil heat exchanger is damaged (red).  This causes the lube oil system to overheat and eventually causes the generator and the end user to shutdown (shown as gray).  Once the seawater pump is repaired, the lube oil heat exchanger becomes operable (green), the generator can be restarted, and the end user receives power again after the generator finishes spinning up. Equipment shown as orange requires crew attention to restart. Yellow means the crew is attending it, while fuschia means the device is in start-up mode .


Fire Fighting example

In the next example, a fire is started in several berthing compartments on a cruise ship.  Fire fighting teams are call to set fire boundaries and to put out the fires.  The setting of fire boundaries is indicated by the spaces being outlined in yellow.  Active fire fighting is indicated by the diagonal blue lines.  Smoke is represented by gray/black shading.  The darker the shading, the thicker the smoke.  Fire is indicated by red shading.  The darker the red, the hotter the fire.

The fire fighting teams try to attack the fire in the berthing compartments from the adjacent passageway, but are forced out to retreat when the passageway catches on fire.  They must then put out the passageway fire before they can go back into the passageway and put out the berthing space fires.
