• Keywords and Expressions • Definition of Offshore Structures • Historical Development • Selection of Deepwater Production Concepts
Historical Development
• Fixed structures became increasingly expensive and difficult to install as the water depths increased.
• Most floating production systems, and virtually all of the semi-submersibles, FPSs and FPSOs, produce oil and gas from wells on the seabed, called "subsea wells".
• New oil / gas fields are being discovered in ultra deep water.
Historical Development
• An offshore structure has no fixed access to dry land and may be required to stay in position in all weather conditions.
