There are five main types of fixed platform, ranging from the conventional fixed platform used at depths of up to 150m, to the tension leg platform that can be used at depths of 2000m. .
The main drawback with fixed platforms is that they can only be deployed up to a maximum depth of around 1500m, and cannot be moved. .
The collapse of oil prices in 2014 had a significant impact on the fixed platforms market, hitting its nadir in 2015. Although the market picked up. .
A fixed platform is a type of used for the or . These platforms are built on and/or legs directly planted onto the seabed, supporting a deck with space for , production facilities and crew quarters. Such platforms are, by virtue of their immobility, designed for very long-term use. Various types of structure are used, steel jacket, concrete

Offshore oil and gas production is more challenging than land-based installations due to the remote and harsher environment. Much of the innovation in the offshore petroleum. .
Offshore oil production involves environmental risks, most notably from oil tankers or pipelines transporting oil from the platform to onshore facilities, and from leaks and accidents on the platform (e.g. and .
