The methods in RAMS are consistent with classical procedures for such analyses. It is worth noting that characterization of stochastic loads, including hydrodynamic, wind, slow drift, etc., need to be appropriate if the response is to be captured. The systems being analyzed are dynamical in nature, i.e., the systems have participating natural modes with frequencies in the frequency range of the dynamic loading. RAMS is a powerful tool for design of floating systems. The system can be modeled to as much detail as is available at any stage of the design.
Integrated models allow conceptual designs to be tested for feasibility.
Design changes can be incorporated and the impact on the whole system assessed quickly. Modeling progresses as the system design is developed, all the way from conceptual design to detailed design of components to final design verification. RAMS reduces cycle time during design and provides a smooth path from concept to installation. Of ASME, Vol. Lutes, L. D., and S.
