Document Intelligence for
Offshore Platforms & FPSOs
P&ID extraction, inspection records, and classification society documentation for offshore platforms, FPSOs, and subsea installations. 99.5% accuracy SLA.
In short
Pathnovo delivers engineering document intelligence for offshore platforms, FPSOs, and subsea installations: topsides P&ID digitisation across process, hull, and marine systems, classification society documentation (ABS, DNV, Lloyd's Register, Bureau Veritas, CCS, IRS), subsea equipment datasheets per API 17 series, turnaround work packs, and Day 1 SAP PM / Maximo handover at sail-away rather than 6 to 18 months post-deployment. Reference customer McDermott: 10,247 tags extracted across 600 P&IDs. Active coverage across MODEC, SBM Offshore, Saipem, Subsea 7, TechnipFMC, and major Korean shipyards.
Procuring on FPSO topsides, subsea equipment, or platform modifications? Pair classification-society documentation with Technical Bid Evaluation (TBE) automation to evaluate vendor bids against MR specs in 24 hours, with deviation lists referenced to API 17 series, ASME, and ABS / DNV / Lloyd's class requirements.
Use Cases for Offshore
FPSO topsides P&ID digitisation: process modules, water injection, gas compression, utilities, living quarters
FPSO hull and marine system documentation: ballast, cargo, inert gas, firefighting, mooring, turret / swivel
Platform process system P&IDs: fixed offshore platforms, jack-ups, semi-submersibles, TLPs, spars
Subsea equipment documentation: trees, manifolds, jumpers, umbilicals, flowlines, risers with DNV / ABS classification
Classification society documentation: ABS, DNV (DNVGL-OS), Lloyd's Register, Bureau Veritas, CCS, IRS for class surveys
Offshore turnaround work pack generation: scope, isolation drawings, work authorisation, permit-to-work
Piping MTO from offshore isometrics: topside module fabrication material take-off
As-built tag registers for platform modifications: MoC documentation consolidated across platform lifecycle
HAZOP / HAZID action register digitisation for offshore safety cases: HSE Case / HSE Manual linkage
Mill certificate traceability for offshore structural and topside piping with class-society witness points
Day 1 handover from EPC fabricator (McDermott, MODEC, Samsung Heavy, DSME, HHI) to FPSO operator SAP PM / Maximo
Brownfield FPSO redeployment documentation: asset register reconstitution before sail-away to new field
Why do offshore operators need document intelligence?
Offshore platforms and FPSOs operate under four severe documentation pressures: (1) remote location: physical access to paper archives offshore is impossible during operations, so onshore teams need current structured data for every maintenance / inspection / MoC decision; (2) regulatory weight: class society surveys happen annually / quadrennially with severe commercial consequence for documentation gaps (class notation suspended = vessel cannot operate); (3) high-consequence safety: HSE Cases must be current, HAZOP actions must close, SIS trip functions must reference current P&ID tags; (4) massive document volume: typical FPSO carries 30,000-100,000 technical documents across topsides, hull, subsea, classification, and operational scopes. Manual documentation management at this scale and precision is infeasible without AI extraction.
What is the Day 1 handover benefit for an FPSO?
Traditional FPSO handover from EPC yard (McDermott, MODEC, Samsung, DSME, HHI) to operator is a 6-18 month post-sail-away reconciliation project where engineering documentation is progressively loaded into operator SAP PM / Maximo and class management systems. During this gap, predictive maintenance cannot initialise, PM schedules are reactive, and class documentation gaps surface in the first annual survey. Pathnovo breaks the gap: engineering data extracted during EPC flows directly into operator systems on Day 1 of sail-away. The first class survey and first annual turnaround run from Pathnovo-populated registers, not from reconstructed paper files. For a typical 100,000 BOPD FPSO with production uptime value of $5-15M per day, accelerated operational readiness by 3-6 months is strategic.
Frequently Asked Questions
What offshore documents can Pathnovo process?
Full offshore document spectrum: FPSO topsides process P&IDs, hull marine-system diagrams, subsea equipment datasheets, classification society certificates (ABS, DNV, Lloyd's Register, Bureau Veritas, China Classification Society, Indian Register of Shipping), inspection records from annual / intermediate / special surveys, riser management reports, turret / swivel documentation, umbilical data, SPS / subsea control module drawings, and turnaround work packs. P&IDs, isometrics, datasheets, HAZOP, mill certificates, and compliance registers all covered.
Can Pathnovo handle FPSO-specific documentation?
Yes. FPSOs are a core use case given their document complexity (tens of thousands of topside P&IDs plus marine systems plus subsea plus classification documentation). Pathnovo processes FPSO topsides P&IDs, hull system diagrams, turret swivel documentation, riser management records, and maintains the unique tag numbering conventions used in FPSO operations (often client-specific combinations of Shell, Total, Chevron, Petrobras schemes). McDermott is a reference customer with 10,247 tags extracted across 600 P&IDs.
Do you support classification society requirements?
Yes. Class-society document scope supported: ABS (American Bureau of Shipping) Offshore Vessel Rules; DNV (DNVGL-OS-C101 structural, C102 structural steel, E101 design of offshore steel structures); Lloyd's Register Rules for Offshore Units; Bureau Veritas NR 445 Rules for the Classification of Offshore Units; CCS and IRS. Pathnovo extracts equipment certificates, inspection records, in-service witness reports, and compliance documentation for annual / intermediate / special class surveys.
Which offshore EPC contractors does Pathnovo serve?
Active coverage for global offshore EPCs: McDermott International (reference customer), MODEC, SBM Offshore, Bumi Armada, Saipem, Subsea 7, TechnipFMC, OneSubsea (SLB), Aker Solutions, Samsung Heavy Industries, Daewoo Shipbuilding & Marine Engineering (DSME), Hyundai Heavy Industries (HHI). Indian yards: Larsen & Toubro Hazira, Pipavav / Reliance Naval, Cochin Shipyard. Operator-side: Shell, BP, Equinor, Petrobras, TotalEnergies, Chevron FPSO management teams.
How does Pathnovo support offshore turnarounds?
Offshore turnarounds are logistically compressed (typical shutdown window 14-45 days) with severe documentation-readiness requirements. Pathnovo accelerates five workflows: (1) scope isometric MTO for replacement piping and equipment, (2) weld schedule / NDE plan with class-society witness points, (3) mill certificate traceability for incoming offshore-grade materials, (4) HAZOP / HAZID action register re-validation against updated P&ID, (5) work-pack documentation with permit-to-work linkage. Typical offshore turnaround documentation cycle compressed by 40-70%.
Does Pathnovo support subsea documentation specifically?
Yes. Subsea equipment (trees, manifolds, jumpers, umbilicals, flowlines, risers) carries unique documentation demands: DNV subsea structural standards, API 17A (general requirements for subsea production systems), API 17D (subsea wellheads and trees), API 17E (subsea umbilicals), API 17J (flexible pipe). Pathnovo extracts datasheets, FAT reports, DNV survey reports, and subsea installation records into structured registers compatible with operator asset management systems.
Which standards does Pathnovo extract and validate against for offshore scope?
Offshore topsides and subsea scope draws on ISA 5.1 instrumentation symbols, P&ID conventions, ASME B31.3 process piping, NACE MR0175 sour service materials, SIL safety integrity levels, and CFIHOS handover data classes, alongside the API 17 subsea series and class-society rules (ABS, DNV, Lloyd's, Bureau Veritas).
Are there free templates for offshore document workflows?
Yes. The P&ID tag extraction template, instrument index template, HAZOP register template, and piping MTO template are free to download and match the structured output Pathnovo delivers from FPSO and platform drawings.
