Finite Element Analysis

Pipex px® Engineering Services Department are able to provide Finite Element Analysis (FEA) on composite & thermoplastic products as part of our comprehensive product design & development service, combined with Siemens Femap, NX Nastran solver and ANSYS.

FEA provides detailed, predictive analysis in both static and dynamic states of complex geometry components, with layer by layer laminate design & verification to support innovation or to assist customers with material selection & optimisation. 

Utilising in-house specialist design software, our team are able to evaluate the behaviour of composite & thermoplastic materials, enabling optimisation of designs prior to prototyping.

FEA has been utilised in the verification of Fibre Reinforced Polymer (FRP) pressure vessels such as ASME X Class II method B & to optimise laminate design to handle structural load requirements for Platform Level Access (PLA) – HUMP®.  This time-effective process allows qualification by discontinuity analysis & negates the requirement for full scale fatigue testing.


Examples of FEA Projects Portfolio:

  • Fixed ‘T’ MARRS® connectors – Design & optimisation of combined top rail & post connector to improve MARRS® fabrication efficiency & reduce overall product cost.
  • Sea Water Reverse Osmosis (SWRO) pressure vessels – 290 no. high pressure offshore SWRO vessels for installation on the BP Clair Ridge Platform in the North sea.
  • Subsea 7 Hub covers – Laminate design of resin infused impact protection covers for subsea valve assemblies during tow out, meeting strict weight limits to suit ROV operational limits.
  • PLA – HUMP® -  Stress of the platform level access units was analysed as they will be undergoing consistent high footfall once installed in 4 central London Stations; Farringdon, City Thameslink, St Pancras & Blackfriars.
  • Blow Out Preventer (BOP) Access platform – Lightweight, rotating, resin infused access platforms to preserve & maintain BOP, & provide quick & safe access/operation in an emergency.
