A nuclear power plant turbine needs to be replaced. A cruise ship needs another engine. When big machines experience problems, they often require big solutions. These fixes take much more than your average piece of duct tape.

World's Toughest Fixes returns for a second season, taking viewers inside some of the most daunting real-world construction and repair jobs imaginable.  Each one-hour episode follows professional rigger Sean Riley as he goes behind the scenes with some of the world’s top mechanics and engineers. 

For each new job, he has to prove to the crew that he’s no mamma’s boy.  It is usually a quick initiation, and before they can finish taunting him, Riley is flexing his engineering muscle helping these experts solve problems of enormous proportions while he explains the fix with his own rousing wit and down-to-earth insight.

A professional rigger with a passion for adventure, Riley is not 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 travels inside the marvels of large-scale industry and shows what happens when things do not always go to plan.


  • World's Toughest Fixes: Operation Cruise Ship
    "Go on a cruise". They said: "In the Bahamas." "It'll be a lot of fun," They promised. Mid ocean in the Caribbean, it's a race against time. This may be Paradise, but Riley's not on vacation…. He's on his way to a titanic fix. An enormous, 90,000 ton cruise ship is steaming towards one of the world's largest dry docks. They need to install a new power plant… an enormous diesel generator… but first they have to land this ship.

  • World's Toughest Fixes: Going Nuclear
    It's radioactive time. Just getting into this fix takes a lot of nerve… and a full hazmat suit. Riley keeps one eye on his Geiger counter and the other on an operation few ever get to see… a steam turbine upgrade in a nuclear power plant. Even with the reactor shut down, the worksite is a potential radiation zone… It takes an army of technicians to do this job… and keep the area safe from "hot" particles. The goal 50 megawatts more power! They're installing a new hi-tech turbine that packs way more punch.
