FE Analysis

Key Technology
Advanced numerical analysis is central to developing effective solutions to today’s engineering challenges. Our staff includes a team of technical specialists with extensive, advanced FEA experience gained largely in the oil and gas sector.

This specialist knowledge, combined with a responsive and proactive approach to problem solving and sound practical engineering skills underpins the full range of our technical services.

Application
Our state of the art ABAQUS FEA system is deployed on a wide range of projects, ranging from detailed 3D analysis of forgings to global models of entire pipeline systems. A few application areas are highlighted below.

Studies
Pipeline lateral buckling and walking analysis, ultimate load assessments, impact analysis, fishing gear interaction analysis, failure investigations, and fitness for purpose assessments to justify use of outwith-code equipment.

Concept, FEED and Detailed Design
Appropriate FE methods are fully integrated into the design of subsea facilities, ensuring accurate performance predictions for pipelines, spools and structures. Pipe-soil interaction, reeling deformations, and post-yield response of HPHT systems are all modelled using advanced non-linear FEA techniques.

Seismic and Dynamic Response
Application of dynamic FE analysis to seismic design. Pipeline span assessments routinely use FE methods to accurately model non-linear effects.

Computational Geomechanics
Conventional P-Y curves and limit equilibrium methods are supplemented by nonlinear FEA as required for foundation design. Analysis of ultimate capacity, stiffness, consolidation, settlement and seismic performance are all routinely performed by our FE team.

Installation Engineering
Marine lifting studies, barge modification, deck float-over simulation, static and dynamic pipelay analysis are performed.
