2 Facility/Area Code
2.1 Facility Code
Facility represents the common term for all installations (e.g. platforms, rigs, vessels, etc.) di-
rectly operated by ConocoPhillips. Facility Code is composed of max. four (4) alphanumeric
characters (Note that facility Tor & H-7, is described in SAP Asset register with 3 characters +one blank character).
A Facility includes associated structures like bridges, tripods, flares, pipelines, risers.
For example; EKOJ is bridged to EKOX, the bridge is there for the purpose of connecting
EKOJ, and therefore the bridge is associated as an area to EKOJ.
The Facility Code and the Area Code shall be registered in the company's equipment register
and document control system as attributes for identifying to which Facility and Area a
documents/equipment is applicable. However these attributes will not form part of the actualDocument/Drawing Number. Below are listed the ConocoPhillips Facility Codes:
NOTE: Any bridges , t ripods , f lares , p ipel ines , r isers, etc. connec ted to a
platform will be covered under one Facility Code, and fur ther identi-
fied through the Area Code, (section 2.2 Area Codes on page 9).

2.2 Area Codes
"Area" as used in COPENS identifies a specific area, module or structure on or connected to a
platform. An Area has defined boundaries and it normally performs a function.
Area Code is composed of three (3) alphanumeric characters. The leading alpha character is
standard and shall not be deviated from, however, the two numeric characters shall be
developed by the design contractor and approved by the project.
The Facility Code and the Area Code shall be registered in the company's document system and
equipment register as attributes for associating a Facility and Area with specific equipment/
documents. These codes will not form part of the actual Document/ Drawing Number.
(see Section 6 Document/Drawing Number on page 201).
Typical examples of Area Code (also showing the applicable Facility Code):
ELDB ELDFISK 2/7 BRAVO
ELDE ELDFISK 2/7 ECHO
ELDF ELDFISK 2/7 FTP
EMBL ELDFISK 2/7 DELTA (EMBLA)

TOR TOR 2/4 ECHO
a) EKOK A00 = Platform General on EKOK
b) EKOX B01 = Bridge EKOX to EKOC
c) EKOA L02 = Pipeline EKOA - EKOM, 17" Oil/Gas
d) EKOM R04 = 17” Oil Import Riser, from EKOA
NOTE: An Area Code will onl y be unique when appear ing together wi th the
applicable Facility Code.
Example: Sub-Area Code B01 (Bridge no. 1) is used for several platforms.
Only in the combination EKOJ B01 will it mean a specific bridge; Bridge
from EKOJ to EKOX.

System 020 - 2-Phase Production Lines
This system covers equipment in connection with multi-phase production lines including
production header to export riser provided that no separation or other process has been carried
out. Separation for well metering only (test separation), where hydrocarbons and water are
recombined after metering, is a separate process belonging to system 140 - High pressure test
separation. Where a line leaves a wellhead platform and crosses a bridge to a processing
platform (for example from 2/4X to 2/4J), the production line limit is the first bridge landing.
The line will then continue in the appropriate system for the recipient platform (110, 120 or 140).
Note 1:
• Includes Production Header, ref system 010
• Test headers are included in system 140
• Production lines without water are also part of system 020.
Note 2:
• 2-phase refers to systems in which hydrocarbons (oil, gas, NGL) and water flow to-
gether. Hydrocarbon mixtures where water is not included are considered single
phase.
• For classification and registration of documentation, only systems and
sub-systems will be used. I.e: 111 Oil/NGL Recycle system will be registered as
110 High Pressure Production Separation.
System 030 – Electr ical Submersible Pumps, ESP
This system covers equipment in connection with 2-phase production by means of electrical
driven pumps installed in reservoir.
SYSTEM GROUP 1 - OIL/NGL PROCESS
System group 1 contains systems that together perform the required processing of produced oil/
NGL/water from production/test header up to the point where the oil/NGL/water is transported to
another platform by pumping or landing.
System 100 - Oil/NGL Process Systems General
The system covers equipment not classified as belonging to a certain sub-system. This may be
equipment operating several systems within group "1".
System 110 - High Pressure Production Separation
This system covers equipment from headers and import risers including HP separation/produc-
tion pumps. If no other separation/process exists, the system covers equipment up to the export
launcher. Including OIL/NGL Recycle.
Note:
• Where there is only one separator, this will be system 110 irrespective of the actual
pressure.
• For gas down stream of a separator: The piping to the first equipment item in the
downstream system shall be part of the separation system. See also
Section 4.4 System Boundaries on page 75.
• System 110 shall not resume following system 150/250 metering.

LP production pumps are included in the system.
System 130 - Not in Use (Doris Oil Storage and Skimmer)
Not in use for existing platforms, information only.The system covers equipment in connection with the storage of oil, the cleaning of produced
water, and the cleaning of waste water from drains, etc.
System 140 - Test Separation
This system covers equipment from header and import risers up to and including the burner
boom. Test production pumps are included in the system.
Note:
• Gas and oil piping from the Test Separator belongs to system 140 up to the tie-in
point to production piping.
• The Test Header and piping up to the test separator are part of system 140.
System 150 - Oil/NGL Metering, Fiscal
This system covers equipment in connection with the metering of produced/transported oil/NGL.
Import metering measures oil brought to the platform.
Export metering measures oil leaving the platform.
Note:
• This system is limited to the metering skid and its immediate connections.
• A new system begins immediately down stream of the metering package, either ex-
port for export oil or the system the oil flows into for import oil.
System 160 - NGL Separation and Stabilising
The system covers equipment in connection with the removal and reclaim of gas from the NGL
separated through the gas dew point conditioning system.
Note:
• This system is not used. Included in system 280.
System 180 - Produced Water
This system covers all equipment in connection with the processing and treatment of produced
water. The upstream limit is the connection to the production separator. For produced water that
is discharged to sea, system 180 also includes the outfall piping. The reject oil return to the proc-
ess is also system 180 up to the connection to the separator piping.
