RASOS software for the probabilistic safety assessment of offshore structures

The RASOS software provides a comprehensive capability for the safety assessment of jacket type offshore structures which includes structural and load modelling, deterministic linear and nonlinear analysis, fatigue and fracture assessment, system reliability analysis using failure tree and simulation approaches and reliability based optimization. The probability of structural collapse can be assessed under conditions of extreme storm, fatigue, ship collision and fire and blast. Typical applications include reassessment of existing structures, design of repair and strengthening measures following accidental damage, in service inspection and maintenance planning and the preparation of safety cases. The benefits include rational inputs for decision making on issues of platform safety resulting in the reduction of costs and improvement of safety.
