during the paint work. They shall be kept clean and free from any residues. They shall be used for painting welded areas, irregular surfaces, sharp corners and cavities,

except in case of inorganic silicate base paints. The paintbrush shall be 125 mm(5) wide at most. The application shall be carried out in such a manner that the film of paint does not show any

brush marks after drying. Runs or ways streaks shall be corrected at once with the paintbrush. On weld fillets paint shall always be applied by paintbrush.

8.2. ROLLER Rollers shall be a maximum of 175mm (7) long.

P70072-000-FO-002 Rev.3

Rollers shall be used for painting extensive flat, cylindrical and spherical areas of considerableradius of curvature, except where inorganic silicate base paints are being used.

Paint shall be applied in parallel runs, starting from the upper part of the structure, and with thenext stroke being given crosswise to the previous one.

REMARK: Irregular portions of the surface or those that cannot be reached with the roller shall bepainted by paintbrush or by spray gun. Two (2) adjacent strips of the same coat of paint shall be overlapped a minimum of 5cm. Paint shall be applied in all cases so that the film does not display blisters, tearing the previous

coat or impregnation with hairs falling off the roller.

8.3. CONVENTIONAL SPRAY GUN This system shall be used for painting extensive areas or where high productivity is desired. The compressed air used in the spray gun shall be free from water or oil. The equipment shall

be provided with separators, containing silica gel and activated carbon, so as to remove waterand oil respectively.

Separators shall be of suitable size and type and shall be periodically drained during thepainting operation.

Painting equipment shall be fitted with air and paint pressure regulators and gauges. Compressed air hoods, nozzles and needle valves shall be the ones recommended by the

manufactures of the equipment for the particular type of paint to be sprayed on. Pressure on the paint in the tank and the pressure of the air on the spray gun shall be adjusted

in accordance with the kind of paint that is being sprayed. The air pressure on the paint in the tank shall be adjusted whenever necessary so as to offset

variations in the height at which the spray gun is raised above the tank. Air pressure in the spray gun shall be high enough to atomize the paint but not so high as to

cause excessive misting, excessive evaporation of solvent or losses due to excessivepulverization.

During application the spray gun shall be held perpendicular to the surface and at a constantdistance such as ensures the depositing of a damp coat of paint, and the paint shall impinge onthe surface still in the form of a spray.

This method of application shall not be used in places subject to strong wind or on extremelythin structures, which would lead to a great wastage of paint.

8.4. AIRLESS SPRAY GUN The airless spray gun should always be used where practicable; being the preferred method of

application. Painting equipment shall have air and paint pressure regulators and gauges. The pressure of the pneumatic pump in the painting equipment shall be adjusted in accordance

with the particular type of paint being sprayed on. During application, the spray gun shall be held perpendicular to the surface and at a constant

distance that ensures the depositing of a damp film of paint, and the paint shall impinge on thesurface still in form of a spray.

On weld fillets paint shall always be applied by paint brush.

8.5. HIGH VOLTAGE ELECTROSTATIC EQUIPMENT A high-voltage electrostatic equipment (90.000V) shall be used; The cure shall be made in a stove with an approximated temperature of 200 C during 20

minutes.

8.6. OPERATOR QUALIFICATIONAll operators shall demonstrate ability and knowledge of pertinent items of this specification bysuccessfully executing a written test and performing related tasks using approved procedures.

Provide field guidance and personnel instruction during stage of blasting and coating applicationoperations;

Provide periodic inspection of work and provide written, auditable reports regarding compliancewith procedures and any operational improvements that could be made.

The Paint Manufacturer shall supply ample and continuous survey of the surface preparation, paint andprotective layer application, its Supervisor absence being forbidden in any stage of the surface treatmentand/or vessel painting.

All surfaces shall be surveyed by VENDORs Quality Control Representative, PaintManufacturer Supervisor and OSX Inspectors before the painting starts, between the coating and after theend. To allow these surveys the VENDOR shall provide safe conditions and suitable light for all treated orpainted parts.

Daily inspection reports shall be prepared and maintained by VENDOR. This report, signed by QualityControl Representative and Paint Manufacturers Supervisor, shall be handed over to OSX for approval.The reports shall indicate the items blasted and coated, surface preparation grade, roughness profile, drylayer thickness of each coating, adhesion level of finished coatings, holiday detector test voltage, materialsused, including batch numbers, location, and outcome of inspections. Defects shall include those identifiedin this specification and SSPC volume 1, Chapter 23, Causes and Prevention of Paint Failure. Thereports shall also indicate ambient relative humidity, dew point temperature, air temperature, and steelsurface temperature before starting paintwork and during the course of day.

All inspection and quality parameter will comply with the requirements described in VENDORs PaintingInspection and Quality Standard that shall be submitted to OSX approval.

The VENDOR shall submit to OSX approval the methods of control and repair of damages to the coatingcaused by block assembly, burn etc.

The works specified here shall not start before OSX, Paint Manufacturer an VENDOR Supervisors havemutually agreed upon the areas to be degreased, labor, scraped and blasted.

11.2. Paints

For each batch of paint received, VENDOR shall compare the results of the quality certificate issued by themanufactures with the paint specification.

11.3. Surface Preparation

VENDOR shall make visual examination to be sure surface is free from dust, oil, rusted areas and otherforeign matter. VENDOR shall compare the surface with the degree of cleanliness specified in the paintingscheme, based ISO-8501-1 standard.

11.4. Profile of roughness

VENDOR shall measure the relative humidity of the air and the ambient and surface temperatures beforestarting paint work. Repeat the measurements during the course of the day, whenever environmentalchanges such as wind, fog and temperature drops occur.

11.6. Film

VENDOR shall examine each film of paint (during application and after exposure) to make sure the work isdevoid of the following kinds of defects: sagging, swelling, wrinkling, cracking, blistering, cratering,impregnation with abrasive and/or foreign matter, peeling off, oxidation and/or corrosion, inclusion of hairsand pores.

Wet film thickness measurements shall be taken at frequent intervals during the application process.

11.7. Adhesion

11.7.1. The adhesion test is essentially a destructive test, so the painted surface, where test isdone, must be repainted or retouched.

11.7.2. As an alternative to testing adhesion to the failure point, the tests can be interrupted whenthe minimum specified adhesion value is achieved. This method precludes the need to repaircoatings damaged by the test. The adherent pull stubs can then be removed by heating(without damaging the paint system) to soften the adhesive.

11.7.3. Sampling shall be done according the instructions below:

For piping: Each sample area comprises 250 meters length intervals or fraction, along theentire piping run,

For equipments and structures: The sample area comprises each 250m2 or fraction ofpainted surfaces of one equipment or structure.

Each adhesion test shall be done according the instructions below: In the sample painted area, bond pull-stub to the coating surface with adhesive and allow it

to cure thoroughly. When it cured, carry out the adhesion test. If the test result shows lackof adhesion, the test shall be repeated at two points diametrically opposite, 1 meter awayfrom the point of the previous test.

If the other two tests display no lack of adhesion, the sample area is approved by theadhesion test. In this case the adjacent initially tested area shall be re-applied (a circle of0,2m radius centered where pull-stub was bonded), with the areas of the subsequent testsareas being retouched.

If both of them display a lack of adhesion, the sample painted area failed in the adhesiontest and must be entirely re-applied.

If one of the two tests (see item a)) displays a lack of adhesion, another two pointsdiametrically opposite the failed point test must be tested. If one of the additional two testsdisplays a lack of adhesion, the sample painted area failed in the adhesion test and mustbe entirely repainted.

If both adhesion tests mentioned in item d) display no lack of adhesion, the sample area isapproved by the adhesion test. In this case the failed tested areas shall be re-applied (acircle of 0,2m radius centered where pull-stub was bonded), with the areas of thesubsequent tests areas being retouched.

11.8. Dry Film Thickness

Measure the thickness at intervals of 25 meters or fraction, along the entire piping run. For huge areas, measure the thickness on every 100 m or fraction of surface of the

equipment. Dry film thickness gauges shall be calibrated daily using certified calibration plates.

Surfaces to be tested shall be dry, clean and free of dry spray before measurements aremade.

The thickness tests shall be witnessed by OSX inspectors.

11.9. Discontinuities

The test to determine discontinuities shall be made after the last coat finish paint. The test to determine discontinuity shall be made in the scheme to be applied for

temperatures lower than 80C. After the application of last coating on the external hull, a film continuity control shall be

carried out through the porosity detector (holiday detector) being a new coating mandatorywhen a discontinuity is detected.

Wet sponge 67 volt holiday detectors shall be used for film thickness of 500 micra or less.High voltage DC holiday detectors, equipped with a flexible brush electrode and set to asuitable voltage shall be used for film thickness exceeding 500 micra. The test voltage for highvoltage holiday detection shall be calculated by multiplying the minimum coating thickness(micra) specified by 4.

The holiday detector tests shall be witnessed by OSX inspectors.

12. ACCEPTANCE AND REJECTION

12.1. Surface PreparationThe surface examined shall not display vestiges of the materials mentioned in Surface Preparation.The surface shall display an appearance identical to the photographic standard sample appearing in theISO-8501-1 standard specified in the painting scheme.

12.2. Profile of Roughness

The profile of roughness shall lie in the range of 30 to 70 micra.

12.3. Relative Humidity of Air; TemperatureThe following criteria shall be used to determine the relative humidity of the air and the ambient andsurface temperatures, with the exception for the Solvent Free Epoxy Paint Cured with Polyamine:

Maximum relative humidity of 85%; Maximum surface temperature: 52C; Minimum surface temperature: 3C above dew point or 5C (whichever is the higher); Ambient temperature: no painting may be done when the ambient temperature is below 5C,

except in the case of paints whose drying takes place exclusively by evaporation of solvents;such paints may be applied provided the temperature is not lower than 2C;

No paint shall be applied if the ambient temperature, surface temperature or relative humidityat the application time are not in accordance with the allowable values mentioned above.

12.4. Film

The following criterion of acceptance is applicable to paint films examined: sagging, swelling, wrinkling,cracking, blistering, cratering, impregnation with abrasive and/or foreign matter, peeling off, oxidationand/or corrosion inclusion of hairs, pores and smudges will not be accepted.

12.5. Adhesion

The painted surface, when tested in accordance with ASTM D-4541-95 A.4, shall be in accordance with thespecified on Section 7.1. In the case of the surfaces included in Section 6.3, the X test must be appliedand the criteria of acceptance is level 3 of the ASTM D-3359 Standard.
