1. GENERAL

1.1 Scope

This Specification defines the minimum functional requirements related to coating works,supply, characterisation and inspections of protective coatings for offshore structures, livingmodules, on- and off-shore production plants, machineries and packages, electricalcomponents and instrumentation.

According to the requirements of this specification, a “Working Procedure” shall beprepared, which has to be taken in consideration the specific needs of the project. In thisdocument, procedures and methods concerning each work and activity (e.g. abrasiveblasting, paint application, cleaning, paint systems selected, inspections, etc.) have to bedescribed in detail.“Working Procedure” before to come into force, shall be submitted to the Company forapproval.

In the appendixes of this specification paint systems applicable to every area are listed. Themain scope of these alternatives is to provide more options to select the paint system toapply. Paint systems that for any reason will be not suitable for a specific project, can beexcluded during the preparation of the “Working Procedure” of the project itself.

Requirements for the selection of topcoat colours of the coatings, according to identificationand code or aesthetic needs, are also provided.

Since the final result can be significantly affected by the quality level of the work executed(e.g. surface preparation, application of various coats, procedures and inspections)requirements that have to be implemented during intermediate steps of coating operations,are mentioned.

As a general rule, the recommendations and instruction listed in the Product Data Sheetspublished by paint manufacturers shall be followed. Possible conflicts and/or discrepanciesbetween Products Data Sheets and this specification shall be submitted to the Company forapproval.

Characterisation of coating material shall be conforming to the provisions of Appendix “E”.

1. GENERAL

1.1 SCOPE

Scope of this Appendix of Functional Specification 20000.VAR.PAI.FUN Rev. 2 is todefine the requirements for the analytical determinations of characterisation and pre-qualifications of coating materials and paint systems, reported in the sheets enclosed tothe Functional Specification.This Appendix is an integral part of the Functional Specification 20000.VAR.PAI.FUN.Rev. 2 and for no reason can be used separately.

1.2 Reference standards

This Appendix refers to the last issue of rules and standards, listed in the general part ofthe specification, which have to be considered an integral part, as well as any othercontractual document, of the whole specification.





2. FUNCTIONAL CHARACTERISTICS


2.1.1 General criteria

According to this Appendix, pre-qualification requirements shall apply to all coatingmaterials and paint systems intended to be used on surfaces exposed to severeenvironmental conditions, as industrial and marine environment, partial and continuousimmersion service and to paint systems applied on external surfaces where a highcosmetic appearance is requested. The section intended for the “ParticularRequirements” of each sheet reports pre-qualification tests requested for the specificpaint system.

All analysis and tests required by this Appendix shall be performed and suitablyreported by independent laboratories, qualified and approved by the Company.

Two-test levels are requested, divided as follows:

a) Tests for the characterization of coating materials, to verify its characteristics,

b) Tests for the characterization of paint systems (namely of the applied paint) to verifyits suitability and performance in the intended environment and use.

2.1.2 Coating materials characterisation test

2.1.2.1 Applicable to all coating materials type

Each coating material to be tested shall be clearly identified, as follows:

a) Commercial name of the product

b) Manufacturer

c) Batch number

For each Batch Number shall be drawn three samples: one will be used for the analysis,while the other two will be kept, for a time not exceeding the shell life reported on theproduct data sheet, for possible checks.

Each coating material shall be tested, as reported in the Table 1.

For two-pack products, the tests shall be performed both for the base and the curingagents.

Shop-primers (pre-fabrication primers) shall not be tested.

2.1.2.2 Zinc rich primers

Zinc rich primer organic or inorganic, in addition to the requirements mentioned on item2.1.2.1, shall be conform to standard SSPC-Paint 20. In particular, it will accepted thezinc rich primer of types I-B and I-C (inorganic) and II (organic); having the minimumrequirement listed in Table 2:

2.1.3 Paint systems pre-qualification tests

2.1.3.1 Preparation of panels for testing

Tests shall be performed on steel panels 5/6 mm thick in accordance with the ISO 1514standard. Standards ISO 1513 and ASTM D 823 shall be taken in due consideration,too.

For each tests, 3 series of 4 panels shall be prepared. One series shall be used for thetest, while the other two shall be identified and kept for possible checks and controls.

Panels shall be treated and painted with the complete paint system listed in the enclosedsheets, according to all requirements provided both by the sheet and by the FunctionalSpecification 20000.VAR.PAI.FUN. Rev 2, including inspections, controls and testingreports of each working step.

If in the sheet the possibility to apply the paint system over shop-primed surface isprovided, the tests shall be performed on panels painted with the shop-primer, whichbecome an integral part of the paint system subjected to pre-qualification. Shop-primer,not necessarily produced by the same manufacturer of the paint system, shall be of typerequired by item 2.6 of the Functional Specification. 20000.VAR.PAI.FUN. Rev. 2

Paint systems, intended to be applied on galvanised steel, on stainless steel or special





alloys, shall be pre-qualified using panels of the same material provided by the sheet,following the requirements and the procedures of the specification.

2.1.3.2 Pre-qualification tests

One panel series, prepared as described on previous item 2.1.3.1, shall be tested, asrequested by each enclosed sheets, according to the requirements listed in Tables 3.1and 3.2.

At least 3 panels, of the 4 used for each test, have to fulfil the acceptance criteria.

Electrolyte, used for the cyclic tests, shall be synthetic seawater according to standardASTM D1141.

Adhesion tests shall be performed using pneumatic tool. For anti-skid paint systems,tests shall be executed without the anti-skid materials.

On painted panels, subjected to cyclic tests, a scratch line has to be made, down tobare steel, having length not less than 50 mm and width not less than 2 mm.
