If national and/or local regulations exist in which some of the requirements could be more stringent than in this DEP, the Contractor shall determine by careful scrutiny which of the requirements are the more stringent and which combination of requirements will be acceptable with regard to the safety, environmental, economic and legal aspects. In all cases the Contractor shall inform the Principal of any deviation from the requirements of this DEP which is considered to be necessary in order to comply with national and/or local regulations. The Principal may then negotiate with the Authorities concerned, the objective being to obtain agreement to follow this DEP as closely as possible.

5. IDENTIFICATION OF TRANSMISSION PIPELINES AND FLOWLINES

5.1 GENERAL

The application of this format shall be subject to approval by Principal and shall only be applied, by exception to (4), to pipelines and flowline systems, including subsea, that fall outside the scope of plant and facility piping and associated piping classes, and are typically designed and constructed to pipeline codes. It shall not be construed as an alternate to identification through piping class as specified in (4) for piping systems that are subject to piping class identification.

Pipeline/flowline number example based on SI units: 273 - P8001 – 25-X65- N 273 P 8 001 25 X65 N Actual Line OD mm Fluid Code Process Unit Number 800 Sequence number Wall Thickness in mm Material (Grade or Yield Strength) Insulation code see (4.3) Line numbering – See (5.2)

Pipeline/flowline number example based on US customar y units: 10.750” - P8001 – 1.000-X65- N 10.750” P 8 001 1.000 X65 N Actual Line OD inches Fluid Code Process Unit Number 800 Sequence number Wall Thickness in inches Material (Grade or Yield Strength) Insulation code see (4.3) Line numbering – See (5.2)

NOTE: On offshore platforms, a location code may be inserted between the piping class identification and the insulation code. If so applied, t he Principal shall define the location codes.

5.2 PIPELINE/FLOWLINE NUMBERING

5.2.1 Act ual Lin e OD

The Actual Line OD is the measured pipe outer diameter in accordance with ISO 3183. 5.2.2 Fluid cod e

See Table 2 in (4.2.3). 5.2.3 Process unit numb ers

5.2.4 Line sequence numb ers

The sequence number for the line shall be a three-digit number from 001 to 999. 5.2.5 Wall Thick ness

The Wall Thickness is the specified wall thickness of the pipe. 5.2.6 Material (grade or yield strength )

(19)

5.2.7 Assig ning line identific ations

Process and utility lines shall be numbered from apparatus to apparatus. Where there is a change in the pipeline/flowline specifications (i.e., Actual Line OD, wall thickness, material, or insulation), the numbering shall also be changed.

Parallel lines shall be numbered separately.

Flowlines passing from one unit to another shall be given line numbers corresponding to the unit of origin, seen in the direction of flow.

Flowlines entering a unit from other sources and not included in any other identification system shall be given line numbers corresponding to the unit they enter.

6. IDENTIFICATION OF SPECIAL PIPE SUPPORTS

6.1 GENERAL

Definition of special pipe support is contained in DEP 31.38.01.29-Gen. All special pipe supports shall be identified by a tag number of the format:

YYY, in which

"XXX" is a one, two-digit or three-digit number used to identify the process unit; see (6.2); "YYY" is a three-digit sequence number; see (6.3)
