Oil rig construction involves the assembly of large structures designed to extract oil and gas from beneath the ocean floor. These rigs can be fixed to the seabed or floating, depending on the water depth and environmental conditions. The construction process includes designing the rig, fabricating components, and transporting them to the installation site. Once on-site, specialized vessels and cranes are used to assemble the rig. Safety measures are crucial throughout the construction process to protect workers and the environment. After completion, the rig is equipped with drilling equipment and systems to manage the extraction of oil and natural gas.
