1. PURPOSE

The purpose of this report is to give the estimated minimum insulation thicknesses for piping, vessel and equipment insulation for the Ormen Lange Onshore Plant. The thicknesses given are to be used for design purposes, such as 3D modelling, so that adequate space for insulation can be allocated for piping, vessels and equipment.

The applicable documents giving the insulation requirements for the Ormen Lange Onshore Plant are stated in chapter 2 of this document.

2. REFERENCES

NORSOK R-004, rev. 2 Insulation of Piping and EquipmentNHT-M50-02037, rev. 03M Piping and Equipment Insulation, Supplement to NORSOK R-004,

rev. 2.Insulation Handbook

3. GENERAL

The basis for the estimated thicknesses is NORSOK R-004, NHT-M50-02037 and experience from previous projects.

Requirements to insulation material build up are stated in NORSOK R-004 and NHT-M50-02037.

The extent of insulation is defined by the process discipline with input from other disciplines, especially safety discipline, and shown on P & IDs.

Possible use of epoxy type Passive Fire Protection material shall be considered for the slug catchers if fire protection is required.

In-line instruments shall be considered part of pipeline and shall follow the same insulation requirements as the pipe.

Personnel protection distance pins shall be designed and installed so that possible damage to the applied coating is prevented.

Equipment installed in pipelines where insulation is required and that requires regular maintenance, replacement, inspection etc., such as probes for corrosion monitoring, are to be insulated with removable insulation.
