Floating Systems

Floating Systems Design and Analysis Testing

For more than 35 years, Stress Engineering Services has been a leading provider of floating systems solutions. Our extensive industry experience, technical distinction, and advanced software programs uniquely position us to successfully optimize the performance, reliability, and safety of your floating system.

At the core of our floating system analytical capability is our proprietary in-house dynamic analysis program, RAMS (Rational Approach to Marine Systems). Unlike other analysis tools, it performs fully coupled dynamic analysis of floating production systems with the mooring, risers, and floating host platform all connected in a single model. The capability of RAMS – combined with our renowned expertise in testing, riser design/analysis, reliability, and materials – uniquely positions us to provide a comprehensive range of services.
