A structural digital twin has been deployed by Swiss company Akselos for Shell Nigeria Exploration and Production’s (SNEPCo’s) Bonga Main floating production storage and offloading (FPSO).
A digital twin is a virtual model of a process, product or service that allows analysis of data and monitoring of systems to head off problems before they even occur, prevent downtime, develop new opportunities and even plan for the future by using simulations.
The FPSO is located 120km south-west of the Niger Delta, in the water at a depth of over 1,000m. SNEPCo is Shell’s deepwater company in Nigeria and operator of the FPSO.
The Bonga Main FPSO which became operational in 2005, has a capacity of 225,000 barrels per day (bpd) of oil and weighs more than 300,000t.
Akselos noted that the digital twin was a model of the Bonga asset. It represents its ‘entire physical counterpart in absolute detail and accuracy’.
The FPSO is the largest asset in the world to be protected by a structural digital twin, the Swiss company claimed
Bonga Asset Manager Elohor Aiboni 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.
The structural digital twin is based on Akselos’ patented reduced basis finite element analysis (RB-FEA) technology and is expected to improve Shell’s operation.
Akselos said the deployment of the simulation technology will enable safe ‘asset life’ extension.
“We are very proud to have reached this important milestone, which represents many months of complex engineering work between SNEPCo and Akselos, Akselos CTO and co-founder David Knezevic said.
Recall that Akselos and UAE-based engineering and contracting company Lamprell in February signed a memorandum of understanding (MoU) for digital projects.
