A typical oil production platform is self-sufficient in energy and water needs, housing electrical generation, water desalinators and all of the equipment necessary to process oil and gas such that it can be either delivered directly onshore by pipeline or to a [[Floating production storage and offloading|floating platform]] or tanker loading facility, or both. Elements in the oil/gas production process include [[wellhead]], [[production manifold]], [[production separator]], [[glycol]] process to dry gas, [[gas compressor]]s, [[Water injection (oil production)|water injection pumps]], [[oil/gas export metering]] and [[main oil line]] pumps.

Larger platforms are assisted by smaller ESVs (emergency support vessels) like the [[United Kingdom|British]] [[Iolair]] that are summoned when something has gone wrong, ''e.g.'' when a [[search and rescue]] operation is required. During normal operations, [[platform supply vessel|PSVs]] (platform supply vessels) keep the platforms provisioned and supplied, and [[anchor handling tug supply vessel|AHTS vessels]] can also supply them, as well as tow them to location and serve as standby rescue and firefighting vessels.
