Azimuth Barring: Preventing Interference in Dynamic Positioning Systems
Azimuth Barring, also known as the "Prohibited Azimuth Zone", is a critical function in Dynamic Positioning (DP) systems that ensures the safe and efficient operation of azimuth thrusters. This functionality prevents thrusters from adopting a configuration where their exhaust water streams interfere with other thrusters or operational equipment.
How Azimuth Barring Works
Azimuth thrusters generate powerful water streams for maneuvering and maintaining position. However, if these streams are directed toward other thrusters, they can create turbulence, reduce efficiency, and compromise system performance. Similarly, the discharged water can interfere with sensitive operational elements such as diving bells or Remotely Operated Vehicles (ROVs).
The Azimuth Barring function imposes restrictions on the angles (azimuths) at which a thruster can operate. These restrictions can either be:
- Fixed: Pre-defined and programmed by the system manufacturer.
- Operator-Selectable: Allowing the operator to manually set barred azimuth limits based on operational requirements.
Key Benefits of Azimuth Barring
- Avoidance of Thruster Interference: Prevents water streams from one thruster from disrupting the performance of others.
- Operational Safety: Protects sensitive equipment like ROVs, diving bells, or subsea structures from potentially damaging water streams.
- Enhanced Efficiency: Maintains optimal thruster performance by avoiding turbulence caused by water stream overlap.
- Customizability: In operator-selectable configurations, users can adapt barred azimuth zones to specific operational needs, enhancing flexibility.
Applications of Azimuth Barring
Azimuth Barring is indispensable in operations requiring precise control and minimal interference, such as:
- Dynamic Positioning in crowded offshore environments.
- Subsea construction and maintenance involving ROVs and diving bells.
- Vessels operating in close proximity to other assets.
By ensuring that thruster exhausts are directed safely, this function plays a vital role in maintaining the efficiency, safety, and reliability of DP systems.
