Project Results

Experts in pipe stress analysis, Project Results is involved at every design stage of the project, from Issued for Review (IFR) to Issue for Construction (IFC). We offer continual functional and practical results, adapting to any piping revisions. Our team utilizes CAESAR II and Intergraph® CadWorx software for comprehensive stress analysis of buried pipelines and facility above-ground piping. Additionally, we perform analysis of nozzle loads at storage tanks and compressor/pumps. We also determine where to anchor or guide piping on racks and calculate the loads on piles and structural supports, allowing for proper structural engineering design.

Transient, also known as surge or water hammer, occurs due to a sudden increase in pressure resulting from a change in the velocity of the moving fluid. This phenomenon can happen when flow is initiated or halted, for instance, during a compressor start-up or shutdown, or when valves close instantaneously. Such actions can generate transient pressure waves that exceed the steady-state operating pressures, which is crucial in CSA and ASME Pipeline Design. By utilizing AFT Impulse software, engineers can perform transient analysis to calculate the transient pressure waves and provide stress analysis recommendations to mitigate the risk of over-pressurizing the pipeline or facility piping.

Developed in-house, this complex software is designed to meet the requirements of API 1102 and accurately assesses whether a buried pipeline is at risk of pipe collapse due to external surface live loads. It performs comprehensive stress analysis, checking for overall effective stresses, girth weld fatigue, and longitudinal weld fatigue. The software also evaluates various modes of failure, including ring buckling, ovality, crushing side wall, and through wall bending, all based on loads applied to the crown of the pipe. 

Once the client process group or Project Results has performed hydraulic calculations  to determine the outside diameter of the pipe based on operating pressures, distances, and flow requirements, the next step in the initial design stage for pipelines and facility piping involves calculating and verifying the minimum wall thickness, type, and grade of pipe. Project Results will refer to the relevant design standards or codes (CSA Z662, ASME B31.8, ASME B31.4, or ASME B31.3) to calculate the minimum wall thicknesses necessary to meet design conditions.

Utilizing HYSIS software, hydraulic calculations based on client project design specifications are performed to determine proper sizing for facility equipment, above ground piping, and buried pipelines. Additionally, liquid hold up, slugging issues and cool down calculations are important elements needed for the client operations team.

The Project Results team specializes in CSA and  ASME Pipeline Engineering Design, for buried pipelines and pipeline systems that adhere to the latest design standards and codes (CSA Z662, ASME B31.8, ASME B31.4) to fulfill client production requirements. We will provide a comprehensive Design Memorandum (DM) that outlines the pipeline design criteria. The client can then utilize this document for procurement and bid purposes.
