-- DeepOcean and Woodside Energy said on Thursday have carried out a simultaneous subsea inspection and 3D scanning campaign at the Sangomar offshore oil development in Senegal, in what the companies described as an efficiency milestone in subsea operations.
DeepOcean said the operation covered 69 subsea structures, including 17 subsea trees, and combined routine inspection work with high-resolution 3D photogrammetry scanning in a single remotely supported ROV campaign.
The approach eliminated the need for separate vessel deployments for inspection and survey tasks and did not require additional offshore personnel.
The companies said the "dual-scope" methodology enabled both inspection routines and 3D scanning to be performed concurrently, cutting offshore time to just over half of what would typically be required for two separate operations, while also increasing data output.
Meanwhile, Woodside said the system combines ROVs equipped with scanning tools, inspection engineers, proprietary subsea imaging software and digital twin capabilities, using photogrammetry to generate 3D reconstructions from subsea imagery and sonar data.
DeepOcean operates across several West African countries, including Congo-Brazzaville, Equatorial Guinea, Gabon and Ghana, where it supports subsea inspection and IMR services for offshore energy developments.
