The information paper provides recommendations to safely manage heading control operations of turret moored Floating (Production) Storage and Offloading (F(P)SO) facilities. F(P)SO heading control operations are undertaken to enable surveys, installation works, maintenance works and associated F(P)SO operations, often while the facility remains in operation, and are exposed to a wide range of hazards.

It provides guidance on the risks and consequences of loss of F(P)SO heading control, outlines heading control assurance guidance and details potential hazards as well as F(P)SO redundancy measures. The guidance also covers crew training and competency considerations, requirements for F(P)SO deck equipment, Heading Control Tug suitability and communications procedures. To improve the management of heading control operations, the information paper also includes an assurance tool and a standard methodology to calculate the bollard pull requirements for Heading Control Tugs (HCTs). The methodology has been developed in close cooperation with the Maritime Research Institute Netherlands (MARIN).
