WHY THIS EXISTS

XE Enhanced Safety™ Helidecks

The most critical moments of helicopter operation are during landing and takeoff. An accident at either of these stages can result in hundreds of gallons of jet-fuel spilling from ruptured fuel tanks in the belly of the aircraft.

A helicopter crash and burn scenario is always a frightening possibility – the intense, fuel-based fire will quickly spread on a solid plate helideck, making passenger rescue extremely hazardous. Vital time is lost in combating the fire on the helidecks when all attention should be concentrated on the blazing helicopter instead and creating a safety path for crew and passengers to get to safety.

On unmanned platforms, this problem is even more acute as fire-fighting facilities are limited to start with; outside assistance may simply not be available. Civil Aviation Authorities around the world recognize this risk and require extensive fire-fighting and crash safety equipment to be available and positioned around the deck.

THE PATENTED SYSTEM

XE Enhanced Safety™ Helideck – A patented, passive fire-retarding system

The XE Enhanced Safety ™ helideck was developed to reduce these risks and make passenger safety a top priority. This deck incorporates a patented, passive fire-retarding system which works by allowing burning fuel to pass through holes in the decking at a rapid rate, immediately retarding and completely extinguishing the fire using the thermal properties of aluminium. A full-perimeter drainage system ensures that liquids are channelled, sub-surface, from heli-decking to drain. Spilt fuel is quickly and safely drained away unburned and any remaining vapour burn-off can be extinguished in seconds with minimal water spray. Up to 99% of spilt fuel is recovered unburned.

Passive operation

As this system requires no maintenance, power assist, foam or other fire-extinguishing materials for its operation, it brings about huge cost savings to potential owners of the system. And because only water is required to extinguish a fire on its surface, it leads to further cost savings and is a more environment friendly option.

ENGINEERING ADVANTAGES

Features

Non-slip surface

Our XE Enhanced Safety helideck offers superior non-slip grip and a stay dry surface in any weather.

Modular design

The XE Enhanced Safety ™ helideck is a fully modular design: the deck is pre-fabricated and shipped to you in containers. Site assembly involves bolting only and can be completed within a couple of weeks. The deck is then installed under our supervision.

Aluminium alloy access platforms are maintenance free and lightweight.The safety net frame and net are constructed from marine grade high strength aluminium alloy for maintenance free life. The surface of our XE Enhanced Safety helideck. These come in various punch configurations to suit different users. Easy to lift and easy to assemble because of low weight. Components are lightweight and easy to handle without heavy lift equipment.

INDUSTRY ACCEPTANCE

Fire testing

The XE Enhanced Safety™ helideck has been rigorously tested with multiple fire tests in the presence of Det Norske Veritas, Lloyds Register, the United Kingdom Civil Aviation Authority, International Civil Aviation Authority, ABS, various helicopter operators and manufacturers, public safety groups, offshore safety crews, pilots and user bodies. The first public test was carried out as far back as 1988.

This model of helideck does not need foam or other extinguishing agents to deal with a fire on its surface and only water is sufficient to extinguish the residual fire vapour burn after the bulk of the fuel has been drained off. In recent tests on this helideck attended by representatives from UKCAA, ICAO, DNV, LRS, ABS, a 450l jet fuel fire was controlled [1] in the following times:
Purely passive basis, i.e with no intervention:
under 11 seconds
Assisted by a water DIFFS spray :
under 4 seconds
[1] “A fire is deemed to be under control (fire intensity reduced by 90%) at the point when it becomes possible for occupants of the helicopter to be effectively rescued by trained firefighters” (UKCAA)”

"I was personally impressed by the thinking behind the fire containment properties of the helideck to provide passive safety on its own."

Bernard Valois

Chairman, Rescue & Fire Fighting Working Group, ICAO

"The fire demonstration was well-organized and very convincing. The design offers weight and maintainability advantages, as well as the very effective fire retardant system."

John Hannay

Area Director, United Technology Sikorsky

"…must say that I was impressed by the fire containment capabilities of the deck. The effectiveness of water in putting out the fire was clearly significant."

Jim Tuggey

Director, Bell Helicopter
