Correct spooling practice is fundamental to cable asset integrity. Uneven tension distribution induces crush damage in lower wraps, torque imbalance accelerates armour degradation. Both typically manifest downhole, where the consequences are most severe.

Scope of service

•    Spooling and re-spooling to manufacturer specification

•    Controlled tension and torque profiling across the full drum

•    Cable transfer between drums

•     Line sizes: e.g. 7/32 in., 5/16 in, slickline, monoconductor and multi-conductor }

•    Equipment: spooling unit 36" Capstan

Quality controls

Work performed to a controlled procedure, line tension measured on calibrated load instrumentation, spooling parameters recorded and retained.

Deliverables

Spooling record with tension data, post-service inspection summary

Cable condition management requires measured data, not qualitative assessment. Our testing regime provides operators and contractors with a quantified basis for run/no-run decisions and lifecycle planning.

Scope of service

• Cable preservation treatment (bio-grease application) — application of biodegradable cable grease for corrosion protection and to maintain sealing integrity during pressurised operations

• Wire ductility assessment (WDAD) — mechanical ductility testing to verify wire condition and remaining service life
• Cable brushing and cleaning — mechanical removal of debris, scale, and residual well fluids prior to inspection and treatment
• Insulation resistance (IR) testing — performed on calibrated instrumentation, with results recorded against acceptance criteria
• Conductor continuity and resistance measurement
• Cable diameter verification — outer-diameter measurement along the working length, verifying compliance with flow tube and pressure-control equipment tolerances
• Flow tube inspection and bore verification — dimensional check of flow tubes against cable OD for pressure-control operations
• Trend documentation — all readings logged against historical data to support condition monitoring and lifecycle planning
• Pre-mobilisation fitness assessment — consolidated review and fitness-for-service statement prior to campaign deployment

Quality controls

All electrical test instruments held under a calibration programme with certificates traceable to national standards, instrument identification and calibration status recorded on every test report.

Deliverables

Formal test report with pass/fail assessment, trend analysis, and engineering recommendations, documentation suitable for submission to end clients and audit review.

Drum integrity is integral to cable asset integrity. Our inspection and refurbishment service ensures that drums remain fit for service and compliant with handling and lifting requirements.

Scope of service

•    Visual and dimensional inspection

•    Non-destructive examination [methods: MPI ]

•    Flange, barrel, and shaft condition assessment

Quality controls

NDT performed by approved certified vendor to written technique reports, consumables batch-recorded, acceptance criteria stated on every report.

Deliverables

Inspection report with photographic record, findings, and fitness-for-service statement with Digital QR code.
