02 / ENGINEERING DELIVERABLES

A defined package.
Not a whole EPC contract.

These deliverables can be selected individually. Scope can be limited to drafting or document review under the client's engineering leadership.

01Instrument IndexIssued XLSX/CSV register: tags, signal types, destinations and source/revision references.
02I/O List / Signal Register (AI, AO, DI, DO)Issued XLSX/CSV register: tags, signal types, destinations and source/revision references.
03meter and prover interface scheduleIssued controlled PDF and editable source/register where included in the agreed document register.
04loop diagramsIssued numbered PDF drawing sheets; editable EPLAN/DWG source files where specified.
05cable scheduleIssued XLSX/PDF report: cable/core or terminal references, destinations and connection details.
06marshalling termination drawingsIssued numbered PDF drawing sheets; editable EPLAN/DWG source files where specified.
07document reviewIssued controlled PDF and editable source/register where included in the agreed document register.
Issued documentation, not just engineering hours.

Each selected deliverable is entered in an agreed document register with revision, review stage and file format. Native EPLAN/DWG files, PDFs and XLSX/CSV registers are provided only when included in the RFQ. Optional items shown above are not included automatically.

03 / CLIENT INPUTS & QA

From project inputs
to review-ready files.

Client provides

  • Approved P&IDs, equipment list and functional/design boundaries
  • Current vendor package drawings, tags and instrument datasheets
  • Instrument/motor quantities and required file formats (EPLAN, PDF, XLSX as agreed)
  • Owner's standards register and controlled document numbering templates

Typical review activities

  • Identify unresolved P&ID, tag and interface discrepancies
  • Map device signals, terminal/wire IDs and instrument references
  • Check BOM, I/O, loop and cable schedule consistency
  • Issue comment register and agreed revision for client approval

Acceptance conditions

  • Named engineering reviewer on customer's side
  • Defined technical assumptions and change-control route
  • Mutually approved deliverables, format and number of revisions
  • Any site sign-off and regulated acceptance outside remote package
04 / APPLICABLE REFERENCES

Equipment requirements.
Then local rules.

Listed standards are potential design references, not universal compliance claims. The responsible engineer confirms application, edition, contractual adoption and local rules.

TECHNOLOGY / PROCESS

Relevant technical codes

API MPMS (applicable chapters); relevant custody-transfer metrology rules; IEC 60079 if hazardous-area equipment; IEC 61082 / IEC 81346 for drawing structure and equipment identification where adopted.

Requirements vary by equipment construction and process classification.
UK / MACHINE & ELECTRICAL

United Kingdom context

BS EN 60204-1 for machinery, BS EN IEC 61439 for applicable LV assemblies; site owner specifications.

BS 7671 for in-scope fixed electrical installations; UK conformity/market-placement route confirmed by manufacturer and responsible entity.

Fixed site installation and product documentation are separate work scopes.
CLIENT-OWNED RESPONSIBILITY

Excluded from this package

Meter proving, metrology certification, transaction calculations and safety-function approval stay with accountable metering parties.

No site classification, SIL verification, custody-transfer certification or process/pressure design is supplied in this standard documentation scope.
