Method selection & suitability
Start with the need—not the method.
Screen PICSA service pathways against the asset, operating context, constraints and evidence required.
Early screening
Useful direction.
Conditional by design.
A service label does not prove suitability. PICSA first defines the operational objective and then considers the delivery route, technology, specialist interfaces and verification gates.
This is an early-screening framework. Final suitability depends on verified competence, equipment availability, client procedures and project-specific engineering.
| Service pathway | Typical requirement | Potential route | First gate | Primary consideration |
|---|---|---|---|---|
| Subsea IRM | Existing subsea asset requires inspection, cleaning or intervention | ROV-, diver- or vessel-supported work package | Capability and equipment review | Depth, access, tooling and evidence |
| Construction & installation | New subsea infrastructure requires observation, positioning or intervention support | Platform and tooling selected around installation task | Interface review | Vessel, installation contractor and as-built criteria |
| Asset integrity support | Preparation or inspection access is required for an integrity decision | Preparation, inspection and repair interfaces defined together | Engineering review | Acceptance authority and return-to-service requirement |
| Laser Cleaning | Local corrosion, coating, residue or weld treatment on a suitable substrate | Representative laser-cleaning trial and controlled process window | Sample clean | Material response and downstream finish |
| Protective treatment | Suitable component requires phosphate conversion coating or another verified treatment | Approved preparation and treatment sequence | Specification review | Chemistry, process control and coating compatibility |
| Integrated delivery | Multiple contractors, methods or mobilisation interfaces form one work package | Project-delivery route with defined boundaries and handover | Scope workshop | Responsibilities, schedule, permits and evidence |
