CDMS Electrical Engineers together with its sister company CDMS Consulting Engineers were commissioned by Decmil Australia to provide civil, structural, electrical and mechanical engineering design and detailing services for the Defence Fuel Installation (DFI) remediation project at HMAS Stirling Naval Base on Garden Island, Western Australia. For further details on Functional Safety services provided by CDMS Electrical on this project please contact the CDMS Electrical Team on +61 (08) 9421 9060.
CDMS Electrical Engineering produced Commissioning Procedures, Electrical Drawings, Cable Schedules, Instrumentation Lists and Installation
Documents for the electrical teams to complete the electrical installation.
The project was initiated by an audit that was carried out on the naval base which determined how much of the pipe work and tanks required replacement due to them being at the end of their life.
CDMS Electrical Engineering considered all the requirements from an
electrical point of view. This included:
- Functional Safety Audit against API 2350
- Static earthing, and earthing of pipes and tanks
- Hazardous zones
- Control systems
- Relay logic modifications
The site had a very basic control system and in some cases there was no control system with staff instead having to rely on relay logic. The defence engineering document called for controls that could not be implemented under the scope of this project for this reason. A compromise of modification of the existing logic was implemented.
- The electrical drawings onsite were incomplete which required more site visits and some as-building of drawings.
- There were hazardous areas as part of the project which required assessment and consideration in the design.
For CDMS Electrical Engineering, the project entailed an assessment of the sites functional safety based on the applicable standards for the site. An assessment was completed based on API 2350 which is an international standard for fuel farms. Where possible and within the scope of the work, electrical and control systems changes were specified to align the site to the API 2350 standard, the Department of Defence Engineering design documents as well as other applicable Australian standards.
