Inspecting fixed jacket structures is one of offshore's most operationally intensive tasks

Subsea inspection of fixed jacket platforms traditionally demands inspection-class ROVs, dedicated support vessels, large offshore crews, and significant mobilisation lead times. For operators in high-traffic offshore environments, weather windows are narrow and every day of Wait on Weather (WOW) downtime translates directly into schedule overrun and cost escalation.

The operator required a complete inspection of a 4-legged fixed jacket platform — covering all structural faces, risers, J-tubes, caissons, cathodic protection at 10 predefined locations, and a splash zone inspection — without compromising on data quality or regulatory compliance.

Autonomous deployment where ROVs once dominated

BeeX deployed its autonomous underwater inspection system as the primary platform — operating without a large support vessel and with a significantly reduced onsite crew. The mission was structured as a pilot, directly benchmarking BeeX's capability against conventional ROV performance on a live, in-service asset.

  • General visual inspection of all 4 jacket faces and structural legs
  • GVI of riser guard and boat landing structures
  • Detailed inspection of 2 risers, 3 J-tubes, and 2 caissons
  • Cathodic protection survey at 10 predefined locations
  • Splash zone inspection across designated sections
  • Full geo-referenced anomaly report for direct integration into asset integrity workflow

ROV-grade results. A fraction of the operational footprint.

This engagement proved that autonomous inspection has crossed the threshold from promising technology to operational reality. BeeX delivered the same regulatory-grade coverage as a conventional ROV — with a smaller crew, a lighter surface footprint, and geo-referenced data output that enhances rather than merely replicates conventional inspection value.

For the broader offshore oil and gas sector, this marks a tangible step toward inspection programmes that are faster to mobilise, more resilient to weather, and more cost-efficient to sustain at portfolio scale.
