The customer

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

The Project

Size: 90-110 man-hours
Duration: 3-4 weeks

The Problem

Structural damage prediction needed
Slip resistance for various pads clamp forces
Crush force capacity and tubes permanent deformation (ovality)

Proposed solution

Model tension, pull-test and self-weight in operation
Tensioner crush and emergency squeeze study
Installation, reeling and bending analysis

The simulations

Elastic-plastic stress model for permanent deformation in tubes (FE analysis)
Slip resistance calculation based on normal stresses on the contact surfaces (FE analysis)
Ovality determination for internal components (FE analysis)

Project overall results

Optimised design able to withstand all loading conditions for installation and operation.
Savings over £14,000 for the customer in prototyping and testing (estimate).
Savings of more than 6 weeks in development time (estimate).
