ELI5. How are the solid legs for oil platforms built? those legs go down a thousanf feet or more down to the ocean floor if it’s not a floating platform, so how do they lay those giant legs? Submarines? Cranes?

The legs for oil platforms are built using a process called “jacking”. Jacking involves using hydraulic jacks to lift the platform up, then slowly lowering it onto the ocean floor while simultaneously driving the legs into the seabed. This process is done in stages and can take days or weeks to complete. Once the legs are in place, the platform is secured to the seabed with cables and anchors.
