At Apollo, our practically-experienced marine and subsea team understand offshore assets, helping our clients to work safely in the ever-challenging marine environment. When our supermajor client required a study to be carried to understand the FPSO heading response with varying degrees of propulsion degradation, with our in house marine engineers and naval architects, the natural choice was to approach the Apollo team. Our client required an accurate, practical and confident study to help them make decisions that would have considerable impacts both commercially and operationally. Using traditional engineering and cutting-edge modelling techniques, Apollo were able to look at multiple scenarios and make recommendations to ensure our client could plan their offloading operations safely and effectively, even in the event of lost thruster availability.
