1. SUMMARY This specification is an amendment to DEP 30.46.00.31-GEN and is applicable for the instal-lation of thermal, acoustic and cold insulation at Shell Pernis/Europoort and Moerdijk.

2. OBJECTIVE, SCOPE, PARTIES INVOLVED AND RISK

Objective Application of thermal, acoustic and cold insulation of equipment, above ground piping and tanks. Design requirements and execution of an insulation system should be such that:

• Corrosion under insulation due to ingress of rainwater or condensation of water vapour is prevented.

• Heat loss of equipment and piping is minimised, if economically justified.

• Personnel protection is provided viz. surfaces with a temperature of 70°C or higher, if these present a danger.

• Damage to equipment and piping from exposure to freezing conditions is prevented.

• Condensation, solidification or a too high viscosity is avoided.

Scope This BBS document specifies the requirements and gives recommendations for the engi-neering and application of insulation.

Parties involved Suppliers, principals, engineers, supervisors, consultants and contractors.

Risk This document is, according to the Risk Matrix, potential (L)ow. The risk is covered by this document and by training and application of this document.

3. CONTEXT AND REFERENCES This specification is based on the CINI Manual “Insulation for Industries” (English, latest ver-sion). This specification is an amendment to:

DEP 30.46.00.31-GEN Thermal Insulation

4. GENERAL REGULATIONS

Engineering For new construction projects and major rejuvenation/maintenance works the engineering contractor or the project department shall submit an engineering instruction at the kick-off meeting 03.05.3000 reflecting the basis of design of insulation systems and specification. The insulation instruction shall be approved by the Civil Engineering Section. The economic insulation thickness for hot insulation shall be determined by means of the data of the table below. For those cases where this is not applicable the insulation thickness as indicated in the ta-bles of paragraph 5 shall be used.






The following design criteria shall be used to determine the (economic) insulation thickness:

Hot insulation Cold insulation

Average ambient temperature : 8°C Max. ambient temperature : 25°C Wind velocity : 4 m/s Wind velocity : 0 m/s Capital charge : 17.5% Humidity : 85% Heat cost : US $ 2.5/GJ 1)

Drawings The required thermal insulation and finishing materials for piping and equipment shall be in-dicated and specified on the drawings, including all details with respect to the required me-chanical provisions. The insulation details for cold insulation (supports of piping and equipment) shall be com-pletely indicated on drawings, including all necessary required mechanical provisions and shall be submitted to the Civil Engineering Section for approval.

Materials All materials indicated on the drawings shall be specified with the codes mentioned in chap-ter 6. The use of individual engineering contractor codes is not allowed. The mineral wool materials as indicated in this specification shall be ordered with suppliers who buy from those manufacturers who are prepared to collect and/or recycle used insula-tion materials, or with whom Shell Pernis/Moerdijk has a separate recycling contract in place.

Insulation collars Waterproof insulation collars to avoid water ingress shall be fitted around all protruding parts of tanks, vessels and columns with operating temperatures between ambient and 150 ºC or with intermittent operation. These collars shall be executed in accordance with standard drawing S-10.056 For existing equipment (maintenance), alternative solutions should be submitted to the Prin-cipal for approval, e.g. cellular glass collars (ref. DEP 30.46.00.31-Gen, appendix 9), in case welding on existing equipment is not allowed.

Existing piping and equipment When modifications are made to existing pipe work and equipment, the existing insulation thickness shall be applied.

Electrical tracing In case electrical tracing has been applied under the insulation, the electrical tracing shall be switched off (by others) prior to remove and/or install the insulation system.

Asbestos/Ceramic fibres containing materials One should take into account that existing insulation materials may contain asbestos and/or ceramic fibres. To determine the presence of asbestos samples shall be tested by a Shell approved labora-tory (e.g. Daniel C.Griffith Holland B.V.) The handling of asbestos and or ceramic fibres shall be in accordance with 05.00.1021 Min-erale vezels.

1) Heat costs to be confirmed by the principal at the start of the project.

Tab 1 General Requirements + Installation Instructions CINI 1.3.01 General requirements for the thermal insulation of "hot" pipelines and

equipment. 4.3 Application of the metal

finishing layer. Add to this clause: • Sealing of furrowed edges in the cladding is not required for hot-insulation. • Inexpertly installed or damaged cladding will cause Ingress of water, which

must be allowed to evaporate via the joints in the cladding. In practice it will not always be possible to work without sealing by means of mastic or tape, but this must be very selectively. Example: • Horizontal equipment and piping in the vicinity of water spray systems, no

sealing shall be applied to the bottom segment (between 4 and 8’o clock), and certainly not to the longitudinal joints in this segment

CINI 1.3.02 General requirements for the thermal insulation of "cold" pipelines and equipment.

6.6 SPECIFICATION CODE K 1.3.4 AND K 1.3.5 IN COMBINATION WITH CODE B 1.6.2 For the typical details of the construction of cold insulation see figure 1.

• The insulation material shall consist of pre-formed PUR/PIR sections in accordance with the requirements of CINI 2.7.01, type TARECPIR CR40 (Supplier Coolag Holland B.V. or equal). The total insulation thickness shall be made up of one or two layers, depend-ing on the insulation thickness. Transverse and longitudinal joints shall be overlapping ("ship lapped") in the case of single layer insulation. The inner and outer layer of multi-layer insulation can be butt jointed, seams of multiple layer systems shall be staggered. The outer surface of the inner layer shall be covered with a secondary vapour barrier foil (no overlaps), Mylar Multiplex Foil type TF3/50, or equal. The vapour barrier foil shall be in accordance with the requirements of CINI 3.3.05.

• The outer leg of ship lapped joints and the butt joints of the outer sections are to be fully glued with Foster 81-82 or equal.

• The seams of the secondary vapour barrier foil shall be taped off with 50 mm wide Insu-W-Rapid Multifoil Alu tape.

• Each layer of insulation shall be fixed with Scotch 3M filament tape type 895 or equal, three (3) tapes per meter pipe length.

• The outer primary vapour barrier on both one and two layer systems shall be Insu-W-Rapid IWR 701 Instant Butyl Sealing tape with aluminium backup (300 mm wide minimum for straight lengths of pipe) or TEMBUTIL-ALU PLUS. Overlap shall be at least 50 mm.

• In piping systems at each interruption (a.o. at support locations, valves, flanges etc.), vapour stops shall be installed in accordance with CINI 1.3.53 par 3.4 and CINI 5.1.08.

Where boxes are used the inside of the box shall be lined with the composite vapour barrier (see above).

• Protective jacketing shall be aluminised steel plate. The cladding of straight lengths of pipe shall be fixed with stainless steel tension bands (19 x 0.5 mm). DO NOT use park-ers. The seams need not be sealed.




6.7 SPECIFICATION CODE K 3.3.4 AND K 3.3.5 IN COMBINATION WITH CODE B 1.6.2 • Supply and application of pre-formed PUR/PIR slabs, type TARECPIR CR40 (Supplier

Coolag Holland B.V. or equal). The total insulation thickness shall be made up of one (K 3.3.4) or two layers (K 3.3.5). Transverse and longitudinal joints shall not be overlapping ("ship lapped"). The outer surface of each layer shall be covered with a secondary fac-tory applied vapour barrier foil (no overlaps) (Mylar Multiplex Foil type TF3/50, or equal). The vapour barrier foil shall be in accordance with the requirements of CINI 3.3.05.

• For the insulation of spherical shaped parts of equipment (heads of heat exchangers, columns, tanks, etc.) factory shaped segments (spherically and tangentially shaped) shall be applied. All insulation layers shall be sealed-off on the outside with a vapour barrier foil.

• The PUR/PIR-slabs shall not be glued to the equipment.

• All joints of PUR/PIR outer slabs shall be completely glued with Foster 81-82 or equal.

• The joints of secondary vapour barrier foil shall be taped-off with 50 mm wide Insu-W-Rapid Multifoil Alu tape.

• On other insulation layer 19 mm wide Filament tape CR 110 shall be applied with a cen-tre to centre distance of 25 cm.

• The outer insulation layer shall be fixed with 19 mm stainless steel straps.

• On both the one layer system (K 3.3.4) as well as the two layer system (K3.3.5) a va-pour barrier layer of TEMBUTIL-ALU-PLUS shall be applied on top of the outer vapour barrier foil. Overlap shall be at least 50 mm.

• The complete system shall be finished with aluminised steel plate (Code B 1.6.2). The cladding shall be fastened by means of stainless steel bands (19 x 0,5 mm) instead of parkers and/or blind rivets.

• The use of dispersed PUR/PIR in situ shall be limited as much as possible. For valves and flanges, removable covers are preferred; if this is not possible or desirable, dis-persed PUR/PIR in situ may be considered. The quality of the foam shall be in accor-dance with CINI 2.7.01. In order to facilitate future removal of in situ dispersed PUR/PIR, valves shall be wrapped in a rockwool blanket in accordance with DEP 30.46.00.31-GEN, par. 5.9.3 and appendix 14, prior to dispersing the PUR/PIR. For the same reason it is recommended to apply a non-stick coating to the interior of covers used in this ap-plication.

The cladding of spherical heads/fronts shall be fixed with blind rivets. For the fixation of clad-ding on tank roofs the cladding shall be fixed to a specially designed supporting structure. The joints of cladding do not need to be sealed.
