— A Complete Guide to Instrumentation Package Supply for EPC Projects

In EPC (Engineering, Procurement, Construction) projects, instrumentation package supply is a procurement model where all required instrumentation equipment, control systems, and auxiliary materials are provided as a complete bundled package. Unlike traditional fragmented procurement, package supply places full responsibility for selection, sourcing, integration, inspection, packing, shipping, and technical services with a single supplier. The EPC contractor deals with just one interface and receives a complete instrumentation solution.

This model is increasingly common in large industrial projects because it significantly reduces the EPC contractor‘s management burden—the number of suppliers drops from dozens to one, and the workload for technical clarification, quality follow-up, and schedule coordination decreases dramatically. At the same time, the package supplier’s professional selection capability helps avoid compatibility issues that often arise when mixing instruments from different brands.

With nearly five decades of experience in instrument manufacturing, Anhui Tiankang (Group) Co., Ltd. is one of the few domestic suppliers with the integrated capability to manufacture temperature, pressure, level, and flow instruments, as well as instrumentation cables and explosion‑protected electrical products. This guide provides a comprehensive overview of instrumentation package supply for EPC projects, covering scope, supplier evaluation, workflow, and common risks.

1. What Is Instrumentation Package Supply?

Instrumentation package supply means that the supplier provides a complete, fully functional instrumentation system according to the EPC project‘s technical specifications and instrument list, including but not limited to:

• Process instruments (pressure, temperature, level, flow, analytical)

• Control system equipment (DCS, SIS, GDS, PLC, etc.)

• Instrument panels, cabinets, junction boxes, terminal blocks

• Instrumentation cables, cable glands, cable trays

• Instrument tubing, fittings, and mounting accessories

• Spare parts and special tools

The deliverables include not only hardware but also:

• Engineering and selection services

• Technical documentation and drawings

• Factory Acceptance Testing (FAT)

• Packing, shipping, and insurance

• Site installation guidance and commissioning support

• Operator training and after‑sales service

Core value: The EPC contractor transfers design responsibility, quality responsibility, and schedule responsibility for the entire instrumentation system to the package supplier, achieving “turnkey” instrumentation procurement.

2. Typical Scope of Supply

Depending on project type and scale, the scope may vary. Below is a typical scope of supply:

2.1 Field Instruments

2.2 Control Systems & Cabinets

2.3 Instrument Materials & Accessories

Key principle: The package supplier must supply all accessories required for instrument installation. If omissions are discovered during installation, the supplier shall supply them free of charge.

3. How Does an EPC Evaluate Instrumentation Package Suppliers?

EPC contractors typically evaluate package suppliers across the following dimensions:

3.1 Qualifications & Certifications

3.2 Track Record & Experience

EPCs typically require suppliers to provide references from similar projects in the last five years:

• Power: Complete supply for 2–4 units of similar capacity

• Petrochemical: At least 2 complete instrumentation package supplies for similar units

• Contract value: Some projects require individual contract value above a certain threshold (e.g., RMB 10 million)

3.3 Technical Capability

• Can the supplier perform instrument selection, system integration, and panel design?

• Does the supplier provide complete technical documentation (datasheets, outline drawings, wiring diagrams, installation drawings)?

• Can the supplier support digital delivery (3D models, intelligent P&ID, etc.)?

3.4 Supply Chain Management

• Does the supplier have stable, authorised relationships with major instrument brands?

• Can the supplier coordinate unified delivery of multiple brands and instrument types?

• Does the supplier have a robust vendor management and quality control system?

3.5 Project Execution Capability

• Does the supplier have a dedicated project management team?

• Can the supplier prepare a detailed delivery plan aligned with project milestones?

• Can the supplier provide on‑site installation guidance and commissioning services?

4. Standard Workflow for Instrumentation Package Supply

Phase 1: Bidding & Contract Award

1. Receive tender documents: EPC issues package tender; supplier receives technical specification, instrument list, commercial terms

2. Technical clarification: Line‑by‑line review; confirm deviations in writing

3. Bid submission: Provide complete technical proposal, commercial quotation, and qualification documents

4. Contract signing: Confirm technical attachments, quality plan, delivery schedule, payment terms

Key bid submission contents:

• Equipment supply list (model, specification, quantity)

• Product technical brochures and selection guides

• Technical drawings (outline, installation, wiring)

• Quality documents (ISO certificate, Ex certificate, SIL certificate)

• Reference list (contract copies, user references)

Phase 2: Design Confirmation & Production Planning

1. Design liaison meeting: With EPC and design institute to confirm technical scheme, interface boundaries, documentation requirements

2. Technical document submission: Final datasheets, outline drawings, installation drawings, wiring diagrams

3. Interface confirmation: Communication interfaces with plant‑wide DCS/SIS, cable interfaces, power supply interfaces

4. Production planning: Define production, inspection, and delivery milestones based on project master schedule

Phase 3: Manufacturing & Quality Control

1. Raw material procurement: Sourced from approved vendor list with full traceability

2. In‑process inspection: Intermediate checks on critical processes (welding, heat treatment, calibration)

3. Factory Acceptance Test (FAT) : Per Inspection & Test Plan (ITP)—visual, dimensional, electrical, accuracy, insulation, dielectric strength tests

4. Third‑party witness: Notify owner or third‑party inspection agency as per contract

Typical FAT contents:

• Visual and dimensional inspection

• Insulation resistance and dielectric strength

• Accuracy and linearity calibration

• Ex performance verification (if applicable)

• Communication protocol test (HART, Profibus, etc.)

Phase 4: Packing & Shipment

1. Cleaning & protection: Internal cleanliness; anti‑rust oil on exposed metal surfaces

2. Packing: Moisture‑proof, shock‑proof, rust‑proof per export or domestic transport requirements

3. Marking: Shipping marks (project number, contract number, destination), tag labels, handling symbols

4. Documents with shipment: Certificates, manuals, calibration reports, material certificates

5. Shipment notification: Advise EPC of dispatch date, transport mode, estimated arrival date

Phase 5: Site Service & After‑Sales

1. Receiving inspection: Joint unboxing inspection with EPC and owner; verify quantity, model, documentation

2. Installation guidance: Dispatch personnel to site for instrument installation, cable routing, cabinet placement

3. Commissioning support: Loop checks, parameter setting, system integration testing

4. Training: Train owner‘s O&M personnel on operation and maintenance

5. Warranty service: Fast response during warranty (typically 12–18 months); free replacement of faulty parts

5. Interface Management for Package Supply

Interface management is critical to the success of an instrumentation package project. The supplier must coordinate with multiple parties and clarify responsibility boundaries:

Key document: The procurement interface matrix is an important management document defining responsibility boundaries. The package supplier should confirm interface divisions with all stakeholders at project initiation to avoid disputes during execution.
