Summary
Introduction
Although substantial efforts are now being directed by the maritime industry toward the application of limit-state design approaches, the shipbuilding industry has traditionally used classification society rules for design of trading ships. On the other hand, the offshore industry has more extensively applied first-principles methods based on limit states. It may be said that the design approach for moored ship-shaped offshore structures, such as FPSOs, often takes a form that is a fusion of the two industry approaches.
In a ship-shaped offshore installation, the structures of the vessel are of primary importance because they serve to house and support the systems and equipment needed for the overall success of the enterprise. The ability to correctly and consistently provide the necessary safety margins while meeting the twin requirements of structural safety and economy is key to the design of successful structures. This is where design principles, procedures, and criteria play an important part. Needless to say, successful structures during their life cycle also need to adequately meet the various requirements and regulations on health, safety, and the environment.
This chapter presents principles and criteria for design and strength assessment of ship-shaped offshore structures with a focus on the limit-state approach. The importance of safety, health, and the environment is emphasized. The regulatory framework and international standards pertinent to design and operation are addressed. For additional information, see Barltrop (1998).
