What is offshore structure?

Offshore structures are man-made facilities engineered to operate in harsh marine environments. Primarily used for oil/gas extraction and renewable energy (e.g., wind turbines), their design must safely withstand severe ocean forces, extreme weather, and deep-water hydrostatic pressures.

1. Bottom-Supported StructuresThese structures are anchored directly to the seabed and are typically used in shallower waters:

• Fixed Platforms: Secured by steel-reinforced concrete or pile legs driven into the ocean floor.
• Common in depths up to 1,500 feet.Compliant Towers: Narrow, flexible towers supported by a piled foundation that can yield to water movements in depths ranging from 1,500 to 3,500 feet.
• Gravity-Based Structures (GBS): Massive concrete platforms that rely on their own weight resting on the seabed for stability.
