Emerging Arenas - Atalanta OperationCostal Corvettes HMS Malmö and HMS Stockholm • 2008 • Oct, Formal Request • Dec, Gov. decision • 2009 • Feb – Seaworthiness Inspection • Apr– Sea Lift Ships, SE • May 5th 2009, Arrival Djibouti • May 9th 2009, On Patrol
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 zone • Naval adapted specs of the cutting extinguisher • CCS developed the C330D Marine Unit in close cooperation with Royal Swedish Navy in 4 months

LightWeight 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

Container Cargo – Charlotte Maersk Malacka Strait, July 7th 2010, Cobra deployed T+5 days
Container Cargo – Charlotte Maersk • 8160 TEU • Cobra on deckafter 5 days • Made a difference • Initial explosion set 150 containers on firewith in hours • Hard to get to containers at 1000 C • 11 daystogaincontrol • Unknowncostofdamage
RoRo/RoPax – Lisco Gloria October 2010 - Total loss: 525 000 000 DKR or 68 000 000 Euro
Industrial applications • Nuclear Power Plants • Steel plant • Chemicalindustries and refineries
Nuclear Powerplants Main Objectives • Initial response stabilize conditions with finite resources before municipal FRS arrive • Contain the incident within the fire cell • Prevent contamination (run off water, gases) • Limited ventilation possibilities / undesired • Attack without shut down power supply/transmission • BA operations as last alternative (and in a safer environment)
Specific risks atNuclear Power Plants • Autoxidation (especially insulated pipes) • Fire in transformer stations • Cable channels (over or under ground) • Electrical cabinets and rooms • Indoor explosions • Carbon filters and other ventilation • Battery rooms • Roof fires • Non-sprinklered high risk objects • Confidential risks objects
COBRA Acheivements -Nuclear Power Plants • Efficiency: • The Cobra offers rapid and efficientintervention from a safe position – outside the fire cell. • 1-2 minutes of Cobra intervention will make a dramatic stabilizing effect on the situation. • Containment: • No inside attack • No influence on ventilation • No contaminated water run off • No breach of security barrier / fire cell • Finite resources: • A Cobra attack requires 2 fire fighters and can be fast at the scene before the full team and all resources arrives
COBRA achivements –Nuclear Powerplants • Integrated approach: • If a BA attack and other conventional methods are necessary, it will be in a safer environment for the BA team if you first start the intervention by using Cobra • Suitability: • Dielectric test verified the Cobra for the NPP environment • Attack possible with Cobra without shutting down power supply
Steel plant, example • High fire risk production • Smelter site with complex filter construction • High cost for investments and re-investments • €4,000,000 invested, re-investment at approx €10.000.000 • Heavy investments in sprinkler systems required • Approx €700,000 + 10-20% yearly maintenance • Contious production process • Great revenue loss if production halts
Cobra achivements – Steel Plant • Insurance company recognize Cobra as technology equivalent for sprinkler • Investment in Fast Response Unit, deployed at local Fire & Rescue Service, availiable 24-7 • Investment at 20% of sprinkler • €140.000 instead of €700.000 • Cobra used a handful times, ROI on first use. • In addition, Societal benefits from Cobra at FRS
Chemical industries and refineries • High pressure production • Production stops involve extremly high costs • High risk and costly incidents • Firefighters • Environment • Revenue loss
Cobra achievemnets - Chemical industries and Refineries • Release pressures and fight fires in safe ways • From outside • With use in combination of robot • Reduce environment impact • Minimize revenue loss due to production stops
