A rupture in a jetliner's pressure dome. A nuclear power plant turbine that needs to be replaced. A cruise ship that needs another engine. Repairing live 500,000-volt lines from a platform mounted outside a helicopter. These fixes take much more than your average piece of duct tape. When big industry breaks down, the results can be costly and the fixes dangerous. It takes brave souls with steady hands to get them back up and running. And working alongside them is engineering enthusiast and adrenaline junkie Sean Riley.
World's Toughest Fixes takes you inside some of the most daunting repair jobs imaginable. Each one-hour episode follows Sean Riley as he pushes himself to the limit while working with some of the world's top mechanics, showing viewers how these challenging fixes are tackled.
A professional rigger with a passion for adventure, Riley isn't afraid to strap on a hazmat suit or attach himself to a live high-voltage power line to get the job done. He's seen more than his fair share of perilous situations, but on each job he has to show the crew he knows his stuff. It's usually a quick initiation, and soon Riley is flexing his engineering muscle while helping experts solve problems of enormous proportions. Whether dangling from ropes hundreds of feet in the air or diving close to a construction vessel's propellers, Riley's engineering prowess takes viewers inside the marvels of large-scale industry — and he shows what happens when things don't go as planned.
On June 3rd, 2009 Sean Riley took a trip to the studios of Late Night with Jimmy Fallon. Sean brings Jimmy up into his world of rigging and shows him a thing or two. Watch the clip >>

Sean Riley (known as "Riley" to his friends) is a master rigger, engineering enthusiast and set designer with an expertise in suspension and load transfer involving large masses and difficult access. Creating functional and architecturally sound installations, he has risen to the height of his field. He is the founder and principal rigging designer for Gravity Design Inc., a company based in San Francisco, California, that provides innovative rigging and force management solutions for a wide variety of clients all over the world ? from circus acts to industrial installations.
Riley is always hands-on (welding, constructing, wiring), and though he is no stranger to high-risk responsibility, he has a flawless safety record.
His passion for mechanics is matched only by his passion for extreme adventure. He loves to pull on a diving wetsuit, arc up a blowtorch or dangle from a height that would have most people going weak in the knees just for fun. He drives heavy machinery, jumps off bridges, rock climbs and is a back-country solo survivalist.
Riley studied theater arts at University of California Santa Cruz and has taught college-level theatrical design.

In order to accommodate a turbine replacement, the plant schedules a planned outage and shuts down one of the reactors and one of the cooling towers. Then the team, outfitted in radiation suits, moves in. Massive cranes are operated with surgical precision to remove an outer, then inner casing, and then the old (and contaminated) rotor. A brand-new rotor is delicately maneuvered in and interlocks with a casing that has matching rows of blades. When the turbine is restarted, it runs at 1,800 rpm (revolutions per minute) — and will for two straight years.
The Boeing 767 featured in this episode was backed into a heavy metal fence and a hole was ripped in its aft (back) pressure dome. To install a new pressure dome, the crew first unbolts and removes the vertical tail fin from the plane. Next, they disconnect every wire, cable and hydraulic hose as well as pull off the entire tail section. Now the exposed pressure dome can be removed and replaced with a new one. All wires, hoses and cables are then reconnected and the plane is safely put back together, ready for future flights.
Of all the work these linemen do, the most dangerous is the helicopter-based live line work. Some repair work simply can't be done from aerial bucket trucks or climbing the transmission towers? that's when they call in PSE&G's helicopter. One of the first things helicopter pilots are taught is to stay away from power lines. It's just not a good combination, but as crazy as it sounds, this is what these guys do every day. First, a custom platform will be mounted to the belly of a specialized helicopter. Linemen are harnessed onto the platform wearing a protective metal mesh suit and actually bond onto live lines. Then, they'll be able to touch the live 500,000-volt lines and make repairs? all while the helicopter blades are spinning several feet from the wires.
It takes an elaborate system of cranes and hydraulics to lift and transport the mirror and its housing, called the cell, which together weigh around 50 tons. First, the mirror and cell are moved onto a specialized carriage and placed onto a truck that travels an average of 3 mph on a mountain road to the cleaning facility. There, the bottom of the telescope mirror is cleaned of oil and dirt and the top is recoated with an extremely thin layer of aluminum in a vacuum chamber. Then the mirror is returned to the telescope in the observatory.
Divers go under The Balder and remove the worn-out thruster by unscrewing bolts and attaching cables so it can be lowered and then pulled out from under the hull. A giant crane lifts the old thruster out of the water and onto a waiting barge. Riggers then transfer the cables from that thruster to the new one. The crane drops the new thruster into the water and it is jockeyed into place, assisted by underwater divers, positioning it safely back inside the hull.
