Piping System

Off-skid pipe racks

Example of a plant that has 11 compressors in parallel as well as additional process skids connected.

• Completed both the dynamic and static pipe stress analysis.
• Ensured the entire rack was suitable to withstand the required loads.
• 57,000 combinations of operating conditions were assessed.

Results:

• One comprehensive model significantly reduced the design iterations and the associated costs.
• Integrity & Safety: Operate safely without restriction in compressor run speed.

Flow Induced Vibration on High Flow Centrifugal Compressor Station

• Analysis kept separation margins between acoustical and mechanical modes as large as possible.
• Piping vibration was assessed with FIV pulsation point sources.

Results:

• Integrity: Mitigated vibration risks and potential costly failure during operation.
• Safety: Avoided possible failure of small bore piping.

Pipe Rack Analysis

• Work together closely with piping design and civil engineers to ensure a safe and reliable design.
• Localized stress analysis performed for large bore lines.

Results:

• Integrity & Safety: Code compliant analysis.
• Reliability: Operates safely.

Fractionation Plant Piping Analysis

Stress analysis of new facility.

• New design of the system for sustained, thermal and environmental loads.
• Challenges include design of new piping in a way that it works with the existing system.

Results:

• Integrity and Safety: Eliminated design weaknesses that could result in costly down time and major safety risks.
• Cost: Optimised design that reduced number of required supports.
