Aviation Runway Cleaning Systems Manufactured by Osprey USA

Problem? Rubber and particle build up leads to reduced runway friction values Friction values must be maintained to insure FAA compliance and meet safety requirements Runway downtime results in reduced airport productivity

Runway surface is designed with grooves and rough surface to provide maximum friction even during rain and snow environments

Planes deposit rubber on runway surface, filling in grooves and rocky surfaces. Reduces friction values

Current Mainstream Solution Application of corrosive chemical which breaks down rubber build up, followed by application of thousands of gallons of water and repeated scrubbing with high power steel brooms. Residue is either recovered by vacuum systems or washed to side of runway by water sprayers.

Benefits Can hire a contractor to perform cleaning at a cost to airport budget Chemicals are readily available and can be applied by water sprayers

Drawbacks Damage to Equipment Damage to runways Risk of not achieving sufficient friction readings Messy residue Environmental hazard Exorbitant Cost

Damage to Equipment

Damage to Equipment: Runway Sweepers Metal brooms must be replaced after approximately 80 hours of normal operation. A minimum of 4” broom pattern must be used in order to scrub runway surface, resulting in reduced life expectancy of brooms Replacement Cost: approximately $4000.00 per broom plus replacement and cleaning labor

Damage to Sprayers Corrosive chemical dissolves rubber seals, hoses, pumps, gaitors and valves in chemical sprayers Damages truck tires of equipment involved

Damage to Runways Steel Brooms gradually wear down concrete surface, resulting in the need for costly runway replacement or resurfacing every several years.

When current process results in failed friction readings: Redo Cleaning Process first. If not: Skidabrader (expensive shot blaster) must be used to achieve friction readings -- $0.13 per square foot ($104,000/runway) plus $4500.00 for mobilization Shot blasting severely damages runway surface, which must be replaced after being shot blasted twice Approximately $10 million to resurface asphalt runways. More for Concrete surface

Messy Dissolved rubber creates huge mess, coating machinery and gumming up brooms. Very difficult to clean and work with

Environmental Hazard Chemicals and dissolved rubber contaminate: Seeps into ground water Exposes workers to Chemical hazard. Both components of most popular chemical cleaning agent have caused accidental deaths in humans and have several other severe effects on plant and animal tissue Enormous waste of fresh water to wash chemical off

SOLUTION?

OSPREY

Rubber Removed Surface Intact

BENEFITS You can purchase your own or have us contract to clean your runways Proven effectiveness Minimal wear to runways Huge Cost Savings Reduced manpower Convenient Reduced runway downtime Flexibility/ Accessories Safety Environmentally Sensitive

Proven Effectiveness OSPREY Runway Cleaners have been used effectively since 1992 on airports and roads in Europe, South America and Asia Busiest Airport in the world, Hong Kong Chek Lap Kok uses an OSPREY machine

Minimal Wear on Runway By precision control of water pressure values the Osprey leaves runway surface intact, while lifting all rubber and grit out of grooves and off runway surface

Reduced Manpower Osprey operated by 1 employee Capable of cleaning over 20,000 square feet per hour of operation. Approximately 40 man hours to clean 8,000 feet of runway 100 feet wide Can use personnel to perform other duties instead of just cleaning runway

Huge Cost Savings Reduced number of machines needed to accomplish cleaning No chemical cost No need to replace expensive brooms Reduced manpower wages Extremely low maintenance costs Osprey unit requires minimal daily maintenance

Cost savings cont’d Extends life of runway when compared to traditional cleaning methods Uses include cleaning around terminals, negating the need for scrubber units Used for drain and surface water drain cleaning (with suitable accessories) Can be used to power emergency tools, cutting equipment and fire suppression fog lances

Unique Purchasing Options Osprey Units can be purchased out of Airport Improvement Project (AIP) funds instead of airport dollars. OSPREY-USA is a HUB Zone company so can be purchased using HUB Zone dollars Due to elimination of chemical and rubber debris from environment, grant money is available through the Environmental Protection Agency (EPA)

Convenience Power to clean your runways and terminals when YOU want Instead of contracting out your runway cleaning, the Osprey is easy to operate and can be done on a regular maintenance cycle or when friction values get low, not when the contractor can schedule you in for cleaning Water tank can be filled in 15 minute from a fire hydrant Debris tank emptied in seconds

Reduced Runway Downtime Increased speed and ease of cleaning results in less time a runway must be closed for cleaning

Myths about High Pressure Water Removal Systems Damages Runway Time Consuming Expensive Long set up and break down times

Myth 1: Damages Runway Truth: Although Water can be a very destructive force and will damage the runway if not handled correctly, the Osprey balances several Safety Factors to ensure acceptable rubber removal without damaging runway surface

Safety Factors Water Pressure: There is optimal water pressures depending on surface type. We produce high pressure and Ultra high pressure systems depending on surface type Water Volume: The right amount of water will not damage runway, while increased volumes will. E.g: a grain of sand traveling at 20 feet/second will sting, while a 10 pound stone at the same speed will kill. Nozzle Height: The lower the nozzle, the greater the velocity of the water and the greater likelihood for runway damage

Safety Factors Cont’d Nozzle Angle: Water at a 90 degree angle to the pavement will dig in and increase likelihood for damage. Water at lesser degrees will glance off and ‘peel’ rubber without any damage to surface. Nozzles angles have been finely calibrated to ensure a good clean with no damage Nozzle Rotation Speed: Higher speeds equals more jet strikes per lineal foot and less ‘dwell’ time. This ensures safe cleaning Forward Speed of Truck: Must be balanced with rotational speed of nozzles. Will not damage lights on runway surface. Epoxy is resistant to damage from sprayers

Osprey Safety Mechanisms 20 years of research and development have gone into creating the Osprey, which balances all safety mechanisms to ensure safe cleaning --Fine calibration of water pressure, water volume, nozzle height, angle of nozzle, and speed of nozzle rotation by hand and computer controls allows smooth uniform cleaning that removes rubber, not concrete aggregate, rock, or silicone seals

FOD Reduction Sweepers often leave behind pieces of steel, which break off from brooms. The Osprey eliminates this and other FOD from runway!
