P&ID + Isometric + GA Reconciliation for Indonesia Plant Owners

P&IDs, isometrics, GA drawings, and process drawings reconciled to the LiDAR-captured as-found condition, delivered in your CAD environment for the Cilacap refining (Java) across Indonesia.

Why as-built engineering in Indonesia starts with a reconciliation, not a redraft

Across Pertamina's refining estate, the Bontang and Tangguh LNG complexes, and the Morowali-Weda Bay nickel-EV-battery processing build-out, a reconciled as-built drawing package is what every regulator, insurer, and digital-twin handover ultimately depends on. Indonesia's industrial electrical engineering market is led by Pertamina's refining and petrochemical assets, the gas-processing and LNG complex (Bontang · Tangguh · Donggi-Senoro), and a fast-growing nickel-laterite to electric-vehicle-battery processing build-out (Morowali · Weda Bay). PUIL 2011 (Persyaratan Umum Instalasi Listrik · the Indonesian wiring rules) and Migas regulations drive the regulatory framework. Indonesia's industrial base was largely built between 1985 and 2010. Pertamina's refining modernisation program (Cilacap · Balikpapan · Dumai) is brownfield expansion. The Morowali / Weda Bay nickel-EV-battery build-out is a brownfield extension of an existing industrial corridor. The brownfield digital engineering offer fits the country's posture directly.

The drafting standards we apply on Indonesia as-built engagements

P&ID and instrumentation drafting follows ISA S5.1 with PIP PIC001 as the reference for process-industry symbology. Isometric drafting follows ISO 6428. Where the operator references PUIL 2011 (general electrical installations) · SNI IEC 60079 (hazardous area) · SNI IEC 61936 · IEC 60909 · Migas K3 (occupational safety) regulations, the deliverable formatting layer aligns to it; line numbering, equipment tagging, and revision-control discipline are invariant.

What you receive · the six as-built deliverables for Indonesia

P&ID Rebuild or Markup

P&ID drafted to ISA S5.1 in your CAD environment (AutoCAD P&ID, SmartPlant P&ID, AVEVA P&ID, Bentley OpenPlant). Where the existing P&ID is recoverable, we mark up to the as-found condition; where it is not, we rebuild from the field plus operator interviews.

Isometric Drawing Production

Isometric drafting from the LiDAR point cloud against ISO 6428 conventions. Spool list, fabrication isometric, and weld-map deliverable structure depending on the downstream workflow.

GA + Plot-Plan Reconciliation

GA drawing reconciled against the as-found equipment layout. Plot-plan updated with the new equipment positions, elevations, and access-route updates. Tie-in to civil + structural drawings where the operator package is integrated.

Process Drawing Updates

Process flow diagram (PFD), heat and material balance, and utility flow drawings updated against the as-found process configuration. Where the process has drifted from the original design (a recurring finding on plants over 20 years old in Indonesia), we document the drift and align the deliverable to the operating condition.

Asset Register + Digital Twin Hand-Off

Equipment tag list, line list, and instrument index reconciled to the point cloud. The full package hands directly to the Wistwin digital-twin platform or the operator's asset-management system with no re-registration required.

Reconciliation Walk + Discrepancy Log

LiDAR-backed reconciliation against the legacy P&ID / GA / isometric package. Every discrepancy logged with point-cloud screenshot, equipment-tag location, and recommended disposition. The log becomes the basis for the formal as-built revision.

Three brownfield as-built engagements we have delivered in Indonesia

Three Indonesian engagements (a Pertamina refinery, a Bontang-region LNG train, and a Morowali nickel processing plant) that show the pattern:

Pertamina refinery (Cilacap)

a 348,000 BPD refinery with 150 kV intake and aging 11 kV switchgear.

The engagement: K3 Migas safety audit demanded current arc flash labels in Indonesian language; full plant re-baseline + protection coordination + PUIL 2011 conformance package.

LNG (Bontang)

an LNG train with 70 kV intake and 6.6 kV distribution.

The engagement: Insulation coordination after lightning event on the 70 kV feeder; SPD selection + ground grid reconciliation + harmonic measurement.

Nickel processing (Morowali)

a HPAL hydrometallurgy plant with 150 kV captive coal-power + 11 kV processing distribution.

The engagement: First-of-kind plant arc flash baseline against international standards while satisfying PUIL 2011 and K3 Migas review.

As-Built Engineering in Indonesia · the questions buyers actually ask

Buyer questions we hear consistently across K3 Migas audit, PUIL 2011 conformance, and TKDN local-content conversations:

Does the study satisfy K3 Migas safety audit expectations?

Yes. The deliverable is structured against K3 Migas inspection checklists for electrical safety, with Indonesian-language arc flash labels and a bilingual executive summary for the audit team.

Is the work compliant with PUIL 2011 and SNI IEC standards?

Yes. The report opens with a PUIL 2011 and SNI conformity matrix mapping every section to the relevant chapter and SNI standard. SLO renewal-ready format.

How do you handle TKDN local-content requirements?

Where TKDN is contractually required, we structure the engagement so that local-content engineering hours fall within Indonesia-based engineering partners. CEng MIE FIE technical authority remains with our chartered engineers.
