Thrusters expand FPSO operating window

摘要

A common challenge for designers of turret moored FPSOs is ensuring alignment of the FPSO to the predominant environmental loading in extreme conditions. Use of thrusters to assist turret moorings under specific operating conditions to secure this alignment improves FPSO response, increases safety, and expands production windows. It is then necessary to carefully engineer the interaction between the thruster and mooring systems so that, should the thruster system fail, its consequences can be safely managed.
