Drones Fly In Alaska's oilfields

No pilot was required when the Aeryon Scout took off into the leaden skies of Alaska to inspect a stretch of oil pipeline.

The miniature aircraft was guided by an engineer on the ground, armed only with a tablet computer.

The 20-minute test flight, conducted by BP Plc last fall, was a glimpse of a future where oil and gas companies in the Arctic can rely on unmanned aircraft to detect pipeline faults, at a fraction of the cost of piloted helicopter flights.

It could become reality as soon as 2015, when the Federal Aviation Administration (FAA) opens up American skies for the commercial use of unmanned aircraft, popularly known as drones.

While technical shortcomings and strict regulation are likely to limit the use of drones in the near term, the rules governing public airspace will be more relaxed in the wilderness of Alaska than in the lower 48 states, industry experts say.

"We're going to take baby steps," said Gary Shane, senior project manager and chief technology officer of BP Pipelines in North America. The company plans to deploy its first drones in the Alaska North Slope within three years, he told reporters.

Laid end to end, the more than 300,000 miles of natural gas pipelines that crisscross the United States would circumnavigate the planet 12 times. There's a lot of money to be saved by reducing the number of manned flights on these routes.

A small, unmanned vehicle fitted with a heat-sensing camera costs about $85,000, while it costs about $3,000 to send a helicopter to monitor an oil pipeline for an hour, said Dave Kroetsch, chief executive of drone manufacturer Aeryon Labs Inc.

The drone, therefore, would pay for itself within 29 hours.

BP began researching the use of unmanned aircraft in 2006. Royal Dutch Shell Plc began a year earlier.

One aim, says Shell, is to track the movement of marine mammals to assess the impact of the company's operations in the seas off Alaska.

The Scout is the flagship product of Aeryon Labs, a private Canadian company based in Waterloo, Ontario - the same university town that gave rise to BlackBerry.

Under a meter in length, the Scout weighs 1.2 kg (2.7 lbs) - tiny when compared with the 1,020-kg MQ-1 Predator drone used by the U.S. military and manufactured by San Diego-based General Atomics.

A camera mounted on the drone transmits a live feed to the operator. In the case of pipeline work, sensors can pinpoint the location of a suspected leak and detect signs of decay, such as cracks or rust, said Ian McDonald, Aeryon Labs' vice-president.

With four rotors and legs allowing for vertical take-off and landing, the Scout can also hover closer to a pipeline than any helicopter could. Proponents of the technology say this will help oil companies to find defects earlier than they can now.

According to a U.S. government report on pipeline safety, the public was quicker to report pipeline leaks than companies' in-house detection systems in a third of cases recorded between January 2010 and July 2012. (http://link.reuters.com/wyk48t)
