“Spending time in Port Fouchon or Venice, Louisiana, you really get a feel for how these two worlds have a complicated marriage.”

A group of 85 welders was part of the team that spent eight months constructing the specialist set. The build was an 85% scale version of the real rig and was set in a large tank, with the main deck more than 50 feet above the water.

“The biggest thing for me was to get the main locations right: the bridge and the drill floor,” says Chris Seagers, the film’s production designer.

“We had limited amounts of research, since the Deepwater Horizon is gone. For instance, with the bridge, we only had four photographs and none showed all of the bridge, so we had to call the manufacturer of the equipment and they kindly gave us a layout of how the bridge was formed.”

Nearly 1,500 tonnes of steel was used for the final build, which included a functioning helipad.
