What is a thruster exclusion zone?

A thruster exclusion zone refers to specific azimuth sectors where the output of thrusters is intentionally limited or restricted. This limitation is typically implemented to avoid interference with other operational requirements or to ensure the safety of personnel and equipment. By designating these zones, a vessel can manage its thruster operations more effectively, ensuring that thrust is applied only in directions that maintain stability and control without causing unintended consequences.

Establishing such exclusion zones allows for better control of movements, especially when working in close proximity to other vessels or during sensitive operations such as lifting or maneuvering. This strategic limitation helps to enhance safety measures while ensuring the efficient functionality of dynamic positioning systems. The concept emphasizes the need to balance operational effectiveness with the safety of both personnel and equipment involved in marine operations.
