d) Operating temperature.

The paint system shall be selected in accordance with the applicable paint system Tablesreported in each Appendix and with the Paint System Sheets of the Enclosures.

2.4 PAINT SYSTEMS QUALIFICATION

2.4.1 Paint systems currently qualified

The paint systems qualified according to the procedure and requirements of the FunctionalSpecification 20000.VAR.PAI.FUN. Rev. 2 are no longer valid; therefore they shall besubmitted to a new qualification process as described and required by this Specification.

Nevertheless the Company, in order to fill the gap following the issue of this Specification,should approve, during the first year after the issue, the application of paint systems currentlyqualified in accordance with the requirements of Functional Specification

20000.VAR.PAI.FUN Rev.2, provided that the selected Paint Manufacturer has demonstratedthe begin of the qualification process of his paint systems according to the requirements of this Specification.

2.4.2 Paint systems qualification

Only the paints and paint systems qualified according to the requirements defined in the Appendix “D” shall be selected and applied.

The qualification process shaIl apply to all coating materials, paints and paint systemsprovided by this Specification, including the materials for repair. In the paint system sheet of the Enclosures the tests required for paint system qualification are listed.

As a general rule, two test levels are required:

a) Pre-qualification step, addressed to evaluate all the data relevant to the proposed paintsystem(s) in order to evaluate their consinstency with the general requirements of theSpecification,

b) Qualification step, addressed to the execution of characterisation tests specified for each paint system with the scope to verify the suitability and performance for theintended environment and service.

All tests and analysis reported in the Appendix “D” shall be performed and certified byindependent laboratories qualified and approved by the Company.The tests and qualification analysis might be executed at Paint Manufacturer laboratories,subject to the audit and assessment of the Company of the real capability (includinginstruments, equipments and the general organisation) of the laboratory to perform the tests

required by the Appendix “D”. The Paint Manufacturer shall prepare a detailed tests schedulein which the timing and location for sample’s preparation and test execution shall be reported;the schedule shall be sent in advance to the Company whom besides to have free access to





Page 13 of 30

the Paint Manufacturer laboratory, reserve the right to attend during the execution of the testwithout notice.

The qualification of a coating material or coating system is not binding for the Company,

which shall select, at its sole discretion, one of the paint system included in the list of qualifiedpaint systems.

Company’s qualification is given for an open-ended term. However the Company reserve theright to require at any time the repetition of one or more of the qualification tests to verify thequality of the coating or as consequence of possible coating failure. If the result of one or more tests is negative, the qualification will be cancelled.

Any modification to the formulation or components of a coating material or system, even if considered minor, made by the producer after the qualification, shall be notified in writing tothe Company. The Company reserves the right to require the performance of part or thecomplete the test procedure, or to accept or reject the modified paint, without further tests.The modified coating material or system - when qualified - may be used in place of theprevious one or as an alternative.

The Contractor is obliged to select one or more paint system from the list of paint systemsqualified by the Company.

Under no circumstance the Company approval of a coating system shall be considered aguarantee from the Company related to the coating materials and repair products and theyperformance, but just as an approval to use it.

2.5 DESIGN AND STEEL IMPERFECTIONS

During the design and the construction of metallic components, the basic criteria listed instandard ISO 12944-3 shall be taken in due consideration.

As far as possible, contact of different metals shall be avoided. In case, due to theunavoidable design requirements, the contact cannot be avoided, a suitable insulated

material (Teflon or similar) shall be installed between the different metals. This includes pipesand related supports, bolts, clips, etc. installed in permanent or intermittent immersed areasand on external areas

The construction shall be designed in such a way that it will not interfere with the abrasiveblasting or paint application according to this Specification. No openings, holes, etc. instructural members shall be less than 60 mm in diameter and the distances betweenstructural members shall be ≥50 mm.

Welding shots, drops and spatters, pores in the weld seams, lamination defects, edges, flamecuts, fragments and dents or any other foreign object not removed during construction shallbe considered imperfections and therefore shall be removed before surface preparation.

The steel imperfections detected before, during or after surface preparation shall be removed

with suitable power tools according to the requirements of standard ISO 8501-3 as follows:

Grade P3: for all surfaces intended to be permanently or intermittently immersed or buried. Edges from flame or mechanical knife cutting shall be rounded to a radius of 2mm.Spot and discontinue welds shall be not permitted on these surfaces.

Grade P2: for all surfaces exposed to marine and industrial environment. Edges fromflame or mechanical knife cutting shall be adequately rounded by tree passes grinding.Spot and discontinue welds shall be not permitted on these surfaces.

In this regard, test data, relevant certificationand track record of use of the proposed systems in similar environmental conditions (bothoffshore and onshore) to support the proposed PFP system’s ability to satisfy therequirements of the project shall be submitted to the Company.

7.2 SCOPE

The PFP systems are generally installed on steel support and structural elements of processequipments, vessels and piping. Their scope is to limit, in case of fire, the steel temperatureto the value of 538°C in order to ensure the integrity of the structure. The FPP system can beinstalled as well as to process vessel containing hazardous substances (e.g. GPL andequivalent substances) to reduce the correlated specific risks such as for example theBLEVE – FIRE BALL and resulting domino effects.

The factors that shall be considered for the selection of the proper PFP systems are asfollows:





Page 22 of 30

1) Load and risk of fire (quantity of hydrocarbon, temperature, volatility and leakageprobability);

2) Equipments subject to high risk of fire (e.g. pumps, compressors, furnaces, etc.);

3) Containment and disposal of possible hydrocarbon leakages from the source;

4) Automated shutdown systems of the plant and/or unit;

5) Interception remote control systems and/or discharge and emergency ventilation of equipments;

6) Lay out of the units, equipments and structures;

7) Equipments’ accessibility (obstruction, irradiations, smokes);

8) Response time in emergency situations of the plant’s personnel and firefighting team;

9) Density of cooling water used in fixed and or portable extinguishing systems;

10) Reliability and redundancy of firefighting systems ;

11) Availability over the time of water supply;

12) Particular risks, e.g. radioactive sources, substances and materials reacting with water,water-soluble materials, etc.

7.3 TYPES OF FIRE

This specification refers to the following types of fire:

“H” Class: Hydrocarbon Fire

“J” Class : Jet-Fire.

7.4 PFP MATERIALS AND APPLICATION

7.4.1 Materials

All PFP materials shall satisfy the requirements of this Specification.

As general rule the PFP material shall consist of an intumescent epoxy mastic reinforced withhybrid carbon and glass fibre.

The PFP system shall be tested at recognised independent laboratory with provenexperience in standards and tests related to hydrocarbon fire.

Before any type of PFP system application the “Type Approval” certificate issued bycompetent authority, shall be submitted to the Company.

Furthermore, the materials shall be tested and pre-qualified by independent laboratories

according to the following procedures and standards:

a) NORSOK M-501 Rev. 4 or 5 (System 5a), tested without topcoat. Where these systemsare applied directly to the process equipments substrate, only primer systems pre-qualified under System 5a of standard NORSOK M-501 Rev. 4 or 5 will be accepted.

b) Underwriter Laboratories (UL) Environmental Test Program and provide writtenconfirmation that products are subject to the “UL Follow Up programme.

c) Documented evidence that the intumescent materials, at saturation, shall not exceed 4%water absorption after 90 days of immersion.

The PFP system shall be compatible with the application of top coat as specified by theCompany.

The PFP system is required to be suitable for application to exposed surfaces of structuralelements, vessel, piping, valves, actuators, flange etc. and shall be appropriate for continuous service in the following conditions:





Page 23 of 30

Humidity: up to 100% in highly saliferous conditions, average value 82%,

Fire deluge: deluge with seawater from the fire protection system with an application rateof up to 20.4 l/m²/min.

The PFP system shall be unaffected by exposure to water (water deluge and/or fire water hoses). It shall also be resistant to general chemical and hydrocarbon damage should thematerial accidentally come into contact with these substances.

7.4.2 Approvals and certifications

The PFP system shall be supplied with Third Party issued “Type and Fire” certificates only;reports, project specific testing may only be allowed with the Company’s approval provided inaccordance with API RP 14G. Therefore Contractor shall provide the data required andobtain a certificate of conformity.

All certificates shall be appropriate for the specific application identified. In particular thecertificates of “Type Approval” must be provided for the following:

“Type Approval” certificates appropriate to type of structure or item being protected.

“Type Approval” certificates for the appropriate type of fire the PFP system is expected towithstand (hydrocarbon pool fire, Jet Fire or combination of both) detailing additionalthickness required to withstand the effects of jet fire.

In the case of Jet Fire Contractor shall produce approval to the standard ISO 22899-1.Furthermore Contractor shall demonstrate in writing the material erosion factor requiredto withstand heat flux of 250 Kw.

7.4.2.1 Tests for hydrocarbon pool fires

Hydrocarbon pool fires are defined as a turbulent diffusion fire burning on a pool of liquidinvoluntarily spilt on to an open surfaces and collected on flooring proof surfaces both on theground and on upper level or into restricted surfaces of the same level. The PFP systemsshall be tested and certified according to standard ISO 834-3.

7.4.2.2 Test for jet fires

The liquefied gasses under pressure do not normally form liquid pools as a result of accidental release but they disperse as a jet of liquid aerosol or vapour. This type of releasesunlikely leads to liquid pools. Similarly the vapour releases disperse like jets. The trigger of aliquid aerosol or of vapour jet can lead to a jet fire with high radiation intensity. The flameslength and width of the jet vary according to the upstream pressure of the release, the size

and geometry of the hole as well as the wind speed if present.

Additionally, the velocity and turbulence of the jet may be highly erosive on certain PFPsystem. These effects may lead to rapid and intense localised damages and subsequentknock-on effects such as structural collapse, loss of containment and escalation.

Although all hydrocarbon fires produce a high heat flux, overall, the jet fire has potentially thegreatest impact due to the combined heat fluxes and erosive effects. Therefore it representsthe most severe fire scenario that a PFP system could be required to resist.

The PFP system shall be tested and approved in accordance with standard ISO 22899-1 andOTI 95 634.

7.4.3 Surface preparation

2.1 GENERAL

Qualification requirements shall apply to all coating materials and paint systems provided bythe Specification. In the section “Specific Requirements” of each Paint System Sheet thequalification tests required for the specific paint s ystem are listed.

The Paint Manufacturer shall arrange, at its own expenses, all tests required by this Appendix. The tests shall be performed and documented by independent laboratory, qualifiedand approved by the Company. The Company reserve the right to attend and inspect thetests execution.

The qualification of a coating material or coating system is not binding for the Company,which shall select, at its sole discretion, coatings that are added to the qualified coatings list.

The qualification of a defined paint system is not binding for the Company that could select,at its discretion, one of the paint systems included in the list of Company’s approved paintsystem list.

The Company’s qualification is given for an open-ended term. However the Company reservethe right to require at any time the repetition of one or more of the qualification tests in order to verify the quality of the coating or as consequence of possible coating failure. If the resultof one or more tests is negative, the qualification will be cancelled.

Any modification, even if considered minor, to the formulation or components of a coatingmaterial or of a coating system already qualified by the Company, shall be notified in writingto the Company. The Company reserves the right to require the performance of part or all of the tests, or to accept or reject the modified product, without further tests. The modifiedcoating material or system - when qualified - may be used in place of the previous one or asan alternative.

Under no circumstance the Company approval of a coating system shall be considered a

guarantee from the Company related to the coating materials and repair products and theyperformance, but just an approval to use it.

2.2 QUALIFICATION PROCEDURE

The qualification process of one or more paint systems develops in to two separate steps:

a) Step 1 - Pre-Qualification
