This Hydrospace Information Report (HIR) is intended to provide basic design considerations with respect to bleed-air pneumatic systems for marine craft equipped with gas turbine propulsion engines or gas turbine service power units with compressor bleed-air capability. It is not considered within the scope of this HIR to cover the equipment driven by this bleed air or other sources of pneumatic power such as power driven compressors.This HIR provides a description of bleed-air pneumatic system elements and identifies parameters required to define the requirements for a detailed specification. Specific design requirements are dependent on the application and should be incorporated in a detailed specification.
