Background


• Managing asset at various stages & process

• Design, maintenance, operation, process safety,

mechanical safety, etc.

• Gain maximum value as per intended design

• Protect HSE & company reputation

Asset Integrity


1. Design control – e.g. Material Selection,

Corrosion Allowance (CA), good design etc

2. Cathodic/Anodic Protection

3. Control Process/environment – pH,

temperature, flow, water, corrodents, OP etc

4. Chemical treatment – e.g. Corrosion Inhibitor

5. Protective Coating and Lining

5 Basic Ways for Corrosion Control

• increased costs • reduced safety • negative environmental impact

New PTS


1. Approved paint system + paint manufacturer

only

2. Sample preparation & lab testing for

qualification

3. Personnel Capability – Inspector & applicator

4. Equipment & Tool Inspection

5. Surface preparation

6. Paint application

7. Inspection before, during & after application

Quality Control to Maximize Paint

Performance


8. Application conditioni. The surface temperature > 3°C above dew point.

ii. The surface temperature is 5°C - 50°C

iii. The relative humidity (RH) < 85%

iv. Free from oil, grease and dust

v. Good weather conditions - No rain, heavy fog, moisture condensation

or blowing sand.

vii. Limited soluble chloride ion

Complexities in Handling Paint Warranty

Issue

@

• Involvement of various stakeholders

• Vague/No warranty terms in contractual agreement

@

• Various paint defect/severity assessment codes and standard (ASTM, SSPC, ISO, NACE etc)

• Liabilities (e.g. Amount, scope, responsibilities etc)

@

• Unable to identify paint failure root cause(s)

• Paint application limitation – limited window, accessibility, surface preparation, RH

@

• Unclear Inspection Test Plan (ITP) – e.g. stages of inspection & type of inspection, TPI

• Unclear Roles and Responsibilities (RACI)

@

• Maintenance Coating – e.g. Paint compatibility issue, accessibility

• Surface preparation – surface profile, sharp edges, type of abrasive

@• Aesthetic – colour faded


• Engagement with various stakeholders – GTS,

owner, paint applicators, paint manufacturers and

etc.

• New PTS to govern the practice.

• Require owner to spell out warranty terms and

condition in contractual agreement with contractors

• Minimum warranty period specified in new PTS

• 7 years for all coatings type

• 10 years for Thermal Spray Application

Mitigation & Way Forward


• Specified code and standard for paint defect

assessment (as per ISO 4628-3 Assignment of Degree of Rusting)

• Warranty is based on selected reference area

( < 1% of total painted surface)

• Beyond surface breakdown acceptable level -the

Contractor shall bear the cost - materials,

equipment, labour, transportation and storage

necessary for the repair

• Lighting for application & inspection – minimum 500

lux



• Compensation coverage shall be on a

diminishing value of 10%

• Coverage starting from 100% until the end of first

year, 90% till the end of the second year and so

on until the end of the warranty period.

• Any dispute – independent consultant to be

appointed by owner & contractors

coatings contract document. For shorter design life the warranty period can be reduced

to meet project requirement based on owner’s agreement.

2.1.3 The severity of corrosion shall not exceed a Ri 3 scale based on ISO 4628-3

Assignment of Degree of Rusting during the warranty period.

2.1.4 The warranty shall be based on the reference area within the structure or facility

involved. Reference area shall be selected at a location with typical corrosive stresses for

the structure. Surface preparation, coating application and the quality of work at the

selected reference area shall be agreed and witnessed by the Owner, the Contractor’s

representative together with TPI. Clear documentation and marking on the structure

showing the reference area shall be made available for the reference of the Owner,
