Inspection & Repair

Maximising asset lifespans and ensuring operational safety is paramount to Sub-drill. Our clients rely on us to deliver comprehensive inspection, recertification, and precision repair services for subsea gaskets, downhole tools, and drilling equipment. Our rigorous QA protocols guarantee transparent, data-driven integrity reporting.

Comprehensive Asset Inspection

Sub-drill utilises advanced inspection methodologies to identify wear, fatigue, and structural anomalies before they lead to operational failure. Our facility in Westhill, Aberdeen provides full process control over all evaluation phases:

Non-Destructive Testing (NDT)

Dimensional Inspection & Laser Mapping

Hardness Testing & Material Verification

Thread Inspection & Connection Gauging

Refurbishment & Component Remediation

When components require remediation, Sub-drill delivers specialised engineering to rebuild, re-machine, and upgrade worn assets. Our fully integrated facility manages the entire repair lifecycle to restore original tolerances:

Precision Mechanical Re-machining

Component Welding

In-House Coating, Plating & Surface Refurbishment

Hydrostatic Pressure Testing & Verification

Our service ensures your equipment returns to the field completely verified and ready for deployment.

Rapid Breakdown Response

Sub-drill reacts quickly to urgent inspection and breakdown repair requirements. Our dedicated operations team closely manages the workflow of every project to provide clients with definitive timelines, accurate delivery updates, and reliable feedback.

FAQ

Initiation & Requirements: What technical data and operational parameters do you need from us to start the design?

To initiate a bespoke design, Sub-drill requires detailed data regarding the tool or gasket’s operating environment and fluid characteristics. This includes maximum and minimum design temperatures, water depths, and the exact chemical composition of the wellbore fluids, particularly H2S and CO2 levels. These parameters are critical for selecting the correct metallurgy and elastomer compounds to prevent premature corrosion or stress cracking.

Additionally, clients must provide the exact physical and regulatory constraints of the project. This encompasses the mechanical load requirements—such as working pressures, bending moments, and tensile limits—alongside dimensional profiles of any existing mating equipment. Finally, specifying the required compliance frameworks, such as API 6A, API 17D, or independent third-party witnessing (e.g., Lloyd’s Register), ensures the final design is fully certified for immediate deployment.
