The Cutting Extinguisher

More bang for buck!

Pooling and SharingSmart defenceSocietal changes in terms of Safety & SecurityUnorthodox situations and missionsLess fundsImplies longer life spans of vessels, less crew, more capabilities

Mitigation of austerity = mitigation of backdraft?

Ultra high pressure water firefighting

coldcut™ cobra concept

Safer FirefightingEfficient & Effective Shipboard FirefightingSaving Environment & Minimizing Collateral Damages

Unique concept

Cuts through virtually any material Suppresses, cools and extinguishes fires from safe position outside of fire roomMobile, high pressure water mist with minimal use of waterThe only method with combined capabilities (penetrating, extinguishing, mobile, minimum of water)

Tech specs - Five main parts

1. High pressure water pump

2. Abrasive vessel3. Hose reel with

The Thermos Effect

Light Weight Composite Structures

Problems “Thermos effect” - Containing fire not an option

Boundary cooling not feasible - Must fight fire in the compartment

How to handle breeched fixed installed fifi systems?

Low classified fire zones? Concealed areas?

BA-attacks adding oxygen, high risk procedure for crew and ship

Solution Cutting extinguisher as standard procedure and for redundancy

Safe position – outside of the fire zone

Fast deployment and boundary cooling from inside of thermos

Mitigates back draught

Buys time for BA to muster

In addition; less water = less stability issues, clearing tool for evac

Emerging Arenas – Atalanta Operation

Problem Swedish Costal Corvettes on open sea mission

Low or none fire zone classification

Neither time, nor funds for retrofitting standard solutions

Solution Cutting extinguisher deemed as equivalent to A-60 fire

Step Measure Tactic Time Personnel required

0. Preventive Fixed systems, insulation,training, awareness, etc.

1. Early detection

Assessment of situation, fire alarm

Immediate 1

2. First Attack,Containment

Portable extinguisher, seal fire zone, I report to XO

Immediate after 1. 1

3. Second Attack,Cobra attack

Break fire development.Boundary cooling from inside at CAPs (S) and fixed systems. Creating time for BA-attack

Immediate after 2. 2

4. BA-attack Safe re-entry procedure, extinguish fire. Cobra attack crew supports BA crew

Effect of 3 in fire zone, & BA crew mustered

2+3

Solution to many issues – Swedish Navy

Efficient intervention from a safe position

1-2 min. Cobra attack makes dramatic effect on the fire development

Intervention without ventilating or entering into the fire zone

Boundary cooling from inside the “thermos”

Requires 2-3 crew and can be introduced prior BA attack muster

Safer environment for the BA-attack and re-entry procedures

Mitigates back draught / flash over

Less water used; less stability issues, less collateral damage

Excellent system for redundancy for breached fixed installed systems

Excellent for out of reach areas; voids, cofferdams and containers

Easy to introduce to present fifi procedures, easy to learn and practice

Less impact on the mission as a whole

Cost efficient solution for retrofitting enhanced fire protection

Can be used as a clearing tool, especially on composite vessels

coldcutTM cutting frame

The coldcut™ cutting frame cuts open cargo bodies on ships, airplanes etc. in emergency situations

coldcutTM pipe cutter

The coldcut™ pipe cutter can be used in areas where there is a risk for explosion, such as gas and fuel pipes

Driven by hydraulics and the head nozzle runs along two chains mounted to the pipe

coldcutTM cold tap

The coldcut™ cold tap is used in both emergency situations and in preventive operations

Opens a hole in cisterns or tanks and offers a safe drainage solution of its contents (gas or fluid)
