The customer

Size: Medium-large enterprise
Sector: Oil and gas industry
Country: Angola

The Project

Size: 140-150 man-hours
Duration: 4-5 weeks

The Problem

Slug induced fatigue calculation
Erosion wear estimation required
Installation and operation mechanical loads needed assessment

Proposed solution

Fluid flow modelling to obtain slug frequency
Modal analysis of the structure to obtain spool natural frequencies
Erosion modelling for various particles content
Mechanical analysis for various installation and operational loads

The simulations

Multiphase transient analysis to capture slugs formation (CFD analysis)
Slugs induced pressure map on the spool. FFT to obtain the frequencies
Modal analysis of the structure and resonance assessment (FE analysis)
Discrete phase modelling (DPM) for erosion calculation (CFD analysis)
Stress analysis for installation/operation loads, induction bends (FE analysis)

Project overall results

Optimised design able to withstand all loading conditions for installation and operation.
Savings over £18,000 for the customer in prototyping and testing (estimate).
Savings of more than 8 weeks in development time (estimate).
