Host Chad Zdenek joins a team that's pulling off an engineering first - dismantling the North Sea's biggest oil rig. As the 400-foot-high monster is towed ashore and then dismantled, Zdenek reveals the story of how, against the backdrop of a global oil crisis, deep water oil engineers raced to build an enormous machine to drill through the sea bed in their search for black gold. As he does, he unearths the dozens of systems that kept the rig pumping non-stop during its 40-year lifespan.
