The legs or "jacket" are built on a beach or in port .Concrete structures are built vertically on top of flotation sections ,metal legs are built horizomtally.
They are towed out to sea and flooded to sink in correct location on sea bed.Topside structures are then craned off barges to provide production and living facilities.The correct term is oil platform.
Rigs are floating exploration barges.

A drilling rig is a structure housing equipment used to drill for water, oil, natural gas from underground reservoirs or to obtain mineral core samples. The term can refer to a land-based rig, a marine-based structure commonly called an 'offshore rig', or a structure that drills oil wells called an 'oil rig'. The term correctly refers to the equipment that drills oil wells or extracts mineral samples, including the rig derrick (which looks like a metal frame tower).
