BMT provides single point mooring monitoring systems that allow operators to safely transfer cargo between tankers and FPSOs or shore sites at higher rates. The systems monitor critical functions like shutdown valves, product pressure and flow, hawser tension, and position. Additional sensors provide environmental data on wind, current, waves, and tide. Data is securely transmitted via proven radio telemetry and wireless Ethernet to displays in control rooms. BMT has implemented these monitoring systems to enhance integrity management of offshore loading systems.

1. Single Point Mooring (SPM) Monitoring
BMT’s Single Point Mooring Monitoring Systems provide
tanker masters and FPSO or Shore Side Control Room
Operators real time operational and environment data
required to manage the integrity of the loading systems
and to make low risk hook up and disconnect decisions.
With it, operators can achieve higher cargo transfer
rates safely and tanker masters can achieve safer buoy
approaches.

BMT’s basic SPM Monitoring System focuses on the following
critical functions/measurements:
• Shutdown valve status and control
• Product Temperature, Pressure and Flow rate
• Product Swivel Leakage tank levels
• Hawser Tension
• Buoy/Tanker position and relative speed
To enhance awareness of the environmental forces at work,
BMT provides:
• Wind speed and direction
• Current speed and direction (focused on Tanker Depth)
• Wave height and tide
Reliable and secure data and command communication employs
proven, dual redundant, high bandwidth, Spread Spectrum,
Radio Telemetry. BMT’s wireless Ethernet dissemination system
for the remote units is proven, robust and secure. Striking, user-
friendly displays are a signature of BMT’s monitoring systems
on both the portable units and consoles in the FPSO/Shore side
control room.
