Avoiding Unnecessary Offshore Rectification

Rectification decisions used design allowables that didn't account for 'as built' conditions or operational data. Uncertainty around anomaly interaction and environmental exposure led to risk-averse, potentially unnecessary interventions.

Inputs and context

Representative sources used during delivery.

Offshore pipeline with known integrity findings
Planned rectification based on design allowable conditions
Delivery Breakdown

A clearer way to plan, assess and justify the work

The workflow moved scattered inspection evidence into a more structured, repeatable and reviewable process.

Challenge

Rectification decisions used design allowables that didn't account for 'as built' conditions or operational data. Uncertainty around anomaly interaction and environmental exposure led to risk-averse, potentially unnecessary interventions.

Why it worked

Spatially consistent internal-external correlation reduced ambiguity and enabled defensible engineering decisions without relying on conservative assumptions.

Delivery focus

Repeatable evidence packs, recorded assumptions, clear change history and outputs suitable for review or handover.

Approach

What changed

Typical delivery steps, designed to be repeatable and reviewable.

01

Internal inspection features correlated with seabed interaction, spans, and material properties

02

ROV video and survey data synchronised to KP for contextual validation

03

Integrity assessments rerun using consistent assumptions and thresholds

Outcomes

Observable impact

Observable outcomes, without over-claiming.

Multi-million cost avoidance by eliminating unnecessary rectification

Reduced offshore vessel days and operational disruption

Improved confidence in rectification prioritisation
