3D at Depth expands subsea vibration and leak detection solution

Subsea LiDAR laser systems provider 3D at Depth has announced the expansion of its non-touch vibration and leak detection solution for underwater assets.

The company’s subsea laser LiDAR (SL3) technology has been used across a number of vibration projects globally in water depths of up to 2,300m.

It can also locate reflective fluids with a higher reflectivity than seawater to locate leaks from production of commissioning fluids, such as mono-ethylene glycol, hydraulic production control fluids and oils.

A recent test conducted by 3D at Depth added 30 millilitres of BP Castrol Transaqua HT oil into a tank and confirmed that with non-tracer additives in the oil, the SL3 technology was able to detect leaks from a distance of 12m.

Additionally, when a light-coloured tracer was used, the SL3 was able to identify leaks up to the full operational range of 45m.

“SL3 technology and our powerful backend algorithms continue to provide critical information to help operators make more informed decisions,” said Neil Manning, COO of 3D at Depth. “Structural and piping vibration can lead to severe consequences that can affect worker safety, environmental protection and corporate liability. Our ability to provide customers with a reliable 3D measurement for vibration identification and leaks while being deployed from a rapid non-touch tool is unique.

“In addition, added integrity value can be shown on the backend of dynamic well centre and pipeline inspection campaigns. Customers can consistently experience additional value beyond the scope of each project as we continue to provide them with the right kind of business intelligence to achieve long term results and minimal maintenance shutdown periods.”
