In Q1 2025, Viewport3 were awarded a third contract from a trusted North Sea diving contractor, having successfully supported them on two previous diver 3D scanning campaigns.
This time, the challenge came from a North Sea operator struggling to engage a Linear Actuator Override Tool (LAOT) with the mating lugs on the actuator of a Subsea Christmas Tree (XMT). The solution required a high-accuracy 3D photogrammetry dataset, captured by saturation divers as part of a subsea inspection campaign.
Attempts to “encourage the fit” by grinding and filing the lugs had already been made to no avail — increasing the demand for accuracy, fidelity, and certainty from the 3D data.
With a tight turnaround, Viewport3 proposed mobilising our 20-megapixel diver-imaging kits, supported by a tailored data-capture procedure and a 3D guidance animation to help the dive team collect the best possible data from the offshore work-site.
After a familiarisation call with the dive team, the vessel mobilised on a busy schedule. Our remote support team were placed on standby, ready to help once scanning was added to the dive team’s 24-hour lookahead.
Armed with their procedure and guidance animation, the divers captured near-perfect imagery that exceeded expectations and achieved the client’s stringent <0.1mm accuracy requirement.
Following reconstruction, QC checks, and the application of LR-approved dimensional analysis techniques, the 3D data revealed insights that traditional inspection couldn’t provide:
The outcome gave the client clarity, confidence, and actionable intelligence — helping avoid wasted offshore time and ensuring operations moved forward with precision.
