Who is responsible for setting the maximum speed setting for the system?

The manufacturer is responsible for setting the maximum speed setting for the system because they design and engineer the gas turbine systems with specified performance criteria and safety parameters. These specifications are based on extensive research, testing, and engineering principles that ensure the system operates safely and efficiently within defined limits.

The maximum speed is a critical operational limit that is determined during the design phase and is based on the capabilities of the materials used, the tensile strength of components, and the overall design of the turbine. Manufacturers provide this information through technical manuals and guidelines to ensure that operators adhere to these parameters for safety and reliability.

Other roles, such as the technician, operator, and inspector, may have responsibilities related to the operation, maintenance, and compliance with the manufacturer's specifications, but the initial setting of the maximum speed is clearly the purview of the manufacturer who has the expertise and data necessary to make those determinations.
