Akselos SA, global advanced engineering simulation technology solution provider, has deployed a structural digital twin for Shell’s Bonga Main FPSO, located 120km southwest of the Niger Delta in Nigeria
The digital twin model is updated with loading conditions and inspection data on a regular basis, providing the ability to carry out structural assessments based on the ‘as is’ condition, from anywhere and at any time.
The structural digital twin, which is based on Akselos’ patented RB-FEA technology, was selected by Shell Nigeria Exploration and Production Company (SNEPCo), Shell’s deepwater company in Nigeria and operator of the 225,000 oil barrel capacity FPSO, because of its ability to realise a number of operational objectives. These include the identification of critical areas for prioritised inspection, maintenance and repair, a reduction in personnel on board the asset, reduced necessity for physical inspections in hard-to-reach areas such as cargo tanks and to support scenario planning for extreme weather events and asset modification.
This simulation technology aims to enable safe asset life extension by replacing the over-conservative estimates made with conventional simulation software with accurate assessments that reflect actual remaining fatigue life.
Elohor Aiboni, asset manager for Bonga, said, “The Bonga Main FPSO heralded a number of innovative ‘firsts’ when it was built back in 2004, so it’s fitting that it’s the first asset of its kind to deploy something as advanced as a structural digital twin.”
