The Hidden Process Behind Removing a 27,000-Ton Giant Oil Rig. Mega Engineering Documentary

Explore how massive offshore oil platforms are removed from the ocean after decades of service. This mega engineering documentary follows the full decommissioning process: controlled demolition, ROV underwater inspection, diamond wire cutting, single-lift removal by Pioneering Spirit, jacket handling, pipeline construction, S-lay pipelay operations, hydraulic lifting systems, offshore wind installation, and final steel recycling. Discover why removing an old oil rig is not simple destruction, but a carefully planned reverse-construction project where thousands of tons of steel must be disconnected, lifted, transported, dismantled, and returned to industry safely.
