A New Lease of Life How 3D laser scanning helps SBM Offshore to speed up FPSO revamps After eight years of service with one of the big five oil producers, one of SBM Offshore's FPSOs was due to be refurbished to operate off the coast of Angola, in the Deepwater Field Development, under a twelve-year lease. However, complex projects are rarely without challenges; the design team at SBM's Kuala Lumpur execution centre quickly realised that the vessel's as-built data was both incomplete and severely out of date. With a tight schedule to meet, SBM turned to laser scanning. A rapid learning curve 'A key issue was that the as-built isometrics did not correlate with the original PDMS model,' explained Chandru Sockalingam, Section Leader of Engineering Information Systems at the SBM Kuala Lumpur office. 'We discussed a strategy with colleagues at SBM Monaco, who hired Scopus, a specialist laser surveying company, to scan the entire vessel on location at the Paenal shipyard in Angola. This proved very effective; once the scan was completed we could then compare it with the AVEVA PDMS model, enabling us to accurately correct the model.' SBM KL had never previously used laser scanning in its projects, so using AVEVA Laser Model Interface (AVEVA LMI) to incorporate laser data within a PDMS model was a new experience for its designers. SBM and Scopus created training manuals, after which it took only two days for a new designer to understand how to work with the laser point cloud data within PDMS. Further issues arising through hardware constraints and the volume of scan data were all solved with the support of LFM Software. continued... AVEVA World Magazine 2014 | Issue 2 p16
