INTRODUCTION

This FBE (fusion bond epoxy) Plant Applied Coating (Supplemental) Specification is to be used for fusion bond epoxy (FBE) single layer (FBE-1) and two layer (FBE-2) external coating of individual pipe lengths at a dedicated coating plant.

The externally coated pipe will be used in buried or submerged service for corrosion mitigation in accordance with the requirements of the latest version of Canadian Standards Association (GSA) GSA Z662, Oil and Gas Pipeline Systems and Company project specific requirements.

This Supplemental Specification is to be used in conjunction with GSA Z245.20-14, Plant-applied External Fusion Bond Epoxy Coating for Steel Pipe. The numbering of clauses in this Supplemental Specification corresponds to that in GSA Z245.20-14. Where no clause number is evident in this Supplemental Specification, there are no additions or changes to the GSA Z245.20-14 requirement. This Supplemental Specification details items needed to meet the requirements of GSA Z662, clause 9; GSA Z245.20-14; and Company project specific requirements.

When coated pipe is to be purchased through a Purchase Order (PO) with a pipe Manufacturer or their representative (a pipe Supplier), the coating Applicator receives the coating PO from the pipe Supplier.

Company has the right not to accept a coating Applicator proposed by the pipe Supplier. Any agreement specific to an individual coating Applicator will be contained in a revision to the Supplemental Specification, a technical agreement or an addendum applicable to that pipe Supplier.

The following are applicable:

• All work shall be done in compliance with applicable Acts and regulations;

• The Company has the right to audit, review, and witness;

• The Company has the right to reject defective materials and work; and

• The Company has the right to make changes.

This Supplemental Specification defines what shall be done and does not address items that cannot be done. Company has the right to stop work where activities are observed that could harm project designated materials such as pipe and coating, facilities, environment, breach of the requirements of this Supplemental Specification, or poses an imminent change to health or wellbeing.

Under no circumstances shall any action or omission of the Company relieve the Applicator of their responsibility for quality of coating systems produced.

TRANS MOUNTAIN PIPELINE l.P. EXPANSION PROJECT SPECIFICATION



For each proposed coating Production Line, a coating plant lay-out drawing and process flow diagram shall be provided to the Company at the time of the proposal. The drawing shall include bare and coated pipe storage locations and truck, rail, and ship (if applicable) loading locations.

A successful Pre-Production Qualification Test (PQT) is required before any production coating can start on each Production Line. The PQT shall be conducted using pipe provided by the Company pipe Supplier. Specific PQT details are provided within the body of this Supplemental Specification.

The primary objective of the PQT is to verify that the materials and processes of the coating Applicator are adequate to achieve the specified as-applied coating properties. The pipe Supplier and coating Applicator shall arrange each PQT so the Company's coated pipe delivery schedule is not adversely impacted.

KINDER*'MOR~!~ '




1.0 SCOPE 1.2 This Supplemental Specification covers CSA Z245.20-14 fusion bond

epoxy (FBE) coating System 1A and System 28 applied externally to bare steel pipe. Company will be buying coated pipe and the pipe Supplier provides the pipe.

1.5 The FBE coating shall be suitable for buried or immersed service, at operating temperatures from -5°C up to 50°C, for a service life of thirty (30) years, and ambient storage, transportation, construction and installation temperatures of -30°C to + 70°C. In open storage, the finished pipe coating shall withstand exposure in sunlight and moisture, with a daytime coating temperature of -30°C to +70°C for a period of twelve (12) months without any detrimental change to coating performance. After twelve (12) months the coating system shall still meet all requirements of this Supplemental Specification.

1.7 The pipeline will be designed with cathodic protection (CP) to minimum requirements of the latest version of CSA Z662, supplemented with project specific Company designs. Applicator materials, processes, and finished coating should not affect the ability to apply CP where FBE coating deficiencies develop while the FBE coating is in service.

1.8 Applicator shall be responsible for complying with all requirements of this Supplemental Specification and other referenced documents. This Supplemental Specification is not all-inclusive and the Applicator is expected to be knowledgeable and experienced to perform the work required by this Supplemental Specification.

Revision 1 I September 24, 2015 I Page 16 of 36


minimum thickness specified in this Supplemental Specification. Application and curing of the two-part shall be in accordance with the Applicator's procedure provide in the applicable ITP.

For each POT five (5) to ten (1 0) pipe joint samples shall be coated with System 1A. Not more than five (5) pipe shall be coated for the stripped and recoated pipe POT. Only one (1) pipe section shall be manually coated for the two-part repair material qualification. Where multiple pipe are coated, the Company shall select the pipe to be cut up for POT testing.

On one (1) selected pipe for each coating system, the total coating thickness shall be measured and recorded. A line shall be drawn on the pipe body coating that is parallel to the pipe axis and the line shall be at least 50cm long. Place an intersection mark on the line every 2cm. Measure and record the coating thickness at each 2cm mark for a total of twenty five (25) consecutive measurements. On another selected pipe, measure the coating thickness along a raised weld and on a circumferential weld used by the pipe mill to join pipe. Measure and record the coating thickness every 2cm along the weld for a total of twenty five (25) consecutive thickness measurements that are 2cm apart. Coating thicknesses shall be in accordance with this Section and Table 6.2.4, of this Supplemental Specification.

POT coating destructive testing shall be in accordance with Appendix A, of this Supplemental Specification.

Company may choose to accept POT results from a previous qualification using identical pipe steel Manufacturers, materials, equipment, processes, abrasives, blasting rates, coating rates, highest amount of Applicator reclaimed powder to be used in each coating layer, application temperatures, cure time/temperature, and key personnel to be used during Company production.

6.1.3 (a) Company will not accept any production stripped and recoated pipe unless the Applicator's stripped and recoated pipe process passes the POT tests. The pipe Supplier will have to provide new pipe for coating to achieve the required coating quantity.
