TransCanada PipeLines Limited Eastern Mainline Project Application

Section 4 Compression

October 2014 Page 4-1

4.0 COMPRESSION

This section provides details regarding the compression requirements for the Project. The information is based on preliminary design and is supported by initial results from hydraulic modelling and field investigation programs. Revisions and refinements are expected as additional data are collected and assessed and as engineering progresses through detailed design.

4.1 FACILITY OVERVIEW

The Project involves adding nine 11 MW (ISO-rated power output) gas turbine compressor packages and associated systems at the following five existing TransCanada compressor sites: Stations 134, 136, 139, 142 and 144. The five existing compressor sites are located in the:

Municipality of Clarington (Station 134 – Bowmanville) Township of Alnwick-Haldimand (Station 136 – Cobourg) Township Tyendinaga (Station 139 – Belleville) City of Kingston (Station 142 – Kingston) Township of Augusta (Station 144 – Brockville)

The compressor unit additions at existing compressor sites are required to offset pressure losses as the gas travels through the pipeline. Once in service, these units will provide the necessary compression at the stations. The existing compressor units will remain available for use during commissioning and initial operation of the compressor unit additions to provide capacity as required. TransCanada will apply to deactivate the older units at a future date as required.

The compressor packages will be equipped with dry low-emission reduction technology and noise-attenuation equipment, and will be housed in a new compressor building in a fully fenced station yard. The building will be erected on concrete footings and foundations. Additional prefabricated, skid-mounted buildings will be erected on pilings and used to house the power generator units, electrical and mechanical equipment, the air system, the utility gas equipment and station personnel, as required. Suction and discharge yard piping will be installed to connect the compressor stations to the Project pipeline, as well as the existing Montréal Line.

For detailed information on the proposed compression facilities, see Table 4-1.

4.6 ENGINEERING DESIGN DETAILS

The proposed compressor unit additions will have a similar design, except for the changes necessary to accommodate any site-specific conditions. Geotechnical assessments are planned for Q3 2014 and will be submitted to the NEB as supplemental information, if required.

Although only one unit will be installed at Station 134, the design incorporates a two-unit building and additional piping and valves to accommodate a potential second unit expansion. All compressor packages will be the same type and model for standardization and consistency. Each site will be designed for unstaffed operation and will be accessible by road.

4.6.1 Power Type and Source

TransCanada will rely on third-party utility power to supply the compressor stations. Auxiliary power units (APUs) will also be installed at all compressor stations for backup electrical power when utility power is offline.

If the power supply to the compressor station is interrupted, a UPS system will provide continuous battery power to the critical control circuits. This UPS system will be capable of maintaining the compressor station control system for about six hours.

4.6.2 Fuel Type and Source

The fuel type is natural gas. The source of fuel will be the connecting pipeline system.

PDF of 37




4.6.3 Station Piping Design

The station piping will include above- and below-ground piping and valves, as determined during detailed design. The station piping will be designed for:

station piping design pressure of 7240 kPa(g) maximum allowable operating pressure (MAOP) of 6450 kPa(g) station piping design temperature of -45ºC to +75ºC

For the piping materials for the compressor stations, see Table 4-5. The material types are appropriate for low-temperature (-45ºC) conditions as they are required to be notch toughness tested (fracture appearance and energy absorption) to a minimum test temperature of -45ºC.

All materials, such as pipe, valves and fittings, will follow TransCanada specification TES-MATL-MD1.

4.6.4 Pipe Coatings

The station pipe coating will follow the TransCanada specifications listed in Table 4-4. The primary coating for the external surface of the below-ground pipe will be fusion-bonded epoxy (FBE). Girth welds will be coated in the field and will be protected with field-applied epoxy coating. Below-ground assembly piping will be protected with a suitable liquid-applied epoxy coating.

Above-ground piping will be primed and painted, and acoustically insulated.

4.6.5 Station Schematics

The proposed compressor unit additions will consist of a compressor building to house the gas turbine compressor packages, auxiliary buildings (electrical/control

PDF of 37




building, mechanical buildings, power unit generator skid, heated storage building, personnel skid and utility gas enclosure) and a skidded drum rack.

The compressor building will be a free-standing steel rigid-frame structure, supported by reinforced concrete grade beams and piles, complete with acoustically designed walls and roof, and will incorporate fire and gas detectors. The auxiliary buildings will be skid-mounted and supported on steel-driven piles. The buildings will be completed with heating and ventilation equipment.

The station suction relief valve will be installed downstream of the station suction isolation side valve and set at 6720 kPa(g) to provide thermal relief for the station suction piping and suction scrubber.

The station discharge relief function will be handled by the automated blowdown valve in accordance with the TransCanada Mainline System standard. The automated blowdown discharge relief valve will be installed upstream of the station discharge isolation side valve and will be sized for the compressor maximum flow rate at the relief valve set pressure of 6720 kPa(g). For the preliminary schematics, see Appendix 4-3.

4.6.6 Pressure Control System

The recycle (anti-surge) valve will be connected downstream of the compressor unit discharge valve and upstream of the unit discharge check valve. The recycle valve will increase the flow through the compressor, as required, to maintain the operating point away from surge by circulating more gas flow and reducing compressor head.

The equipment will monitor actual inlet flow and differential pressure across the compressor through a pressure differential transmitter, and is equipped with algorithms to detect and avoid surge.

The station pressure control will be maintained by increasing or decreasing the compressor speed. The station suction and discharge pressure will be monitored using pressure transmitters. The station pressure setpoints are set by TransCanada’s OCC.

The compressor station OPP system will consist of the pressure-control system as described above, the pressure-limiting system provided by the station controls and unit controls, and the pressure-relieving system provided by the station suction and discharge automated blowdown relief valves.

4.6.7 Station Suction Scrubber

The suction scrubber for the high-pressure gas system will be a swirl/centrifugal type designed to handle the maximum design flow. The scrubber will have automated liquid control to allow for accumulated liquids to be drained to an above-ground storage tank.

PDF of 37




4.6.8 Emergency Shutdown System

An emergency shutdown (ESD) pushbutton will be installed at all exit doors in the compressor building and near the scrubber. Perimeter ESD pushbuttons will be added to all fence gates and tied-in to the single fence ESD. The site ESD pushbutton at the control panel in the control building will trigger a station ESD. Fire or gas detection in the compressor building will also trigger a station ESD. As such, the ESD system can be initiated from multiple locations throughout the compression facility and at each egress point from the compression facility.

The ESD system will trigger the following hard-wired functions during a station ESD:

The gas will be blocked out of the station by the triggered closure of both station suction side valve and discharge side valve, isolating the station from the mainline. Subsequently, the suction blowdown valve and the discharge blowdown valve will both be triggered open to blow down the station piping.

The gas compressor units will be triggered to stop immediately and depressurized throughout the station piping. The units will be completed with a control system that allows multiple types of shutdowns based on different events or scenarios (e.g., one level of shutdown will bring the unit to a complete stop as quickly as possible while maintaining auxiliaries, such as lube oil system).

The blowdown valves and blowdown piping will be installed in a location to discharge gas at a safe distance from the compressor building, auxiliary equipment and the surrounding area.

The ESD system will be capable of isolating the compression facility from the pipeline and depressurizing the compression facility.

The ESD system will be powered by a UPS system, but will be wired fail safe, so that in the event of power loss it will isolate and depressurize the facility to put it into a safe state.

4.6.9 Corrosion Control

The compressor station piping and facilities will be cathodically protected by impressed current CP systems. The systems will include appropriately located and sized anode groundbeds and power sources (i.e., rectifiers and thermoelectric generators) as determined by detailed design. The CP systems will be designed in conjunction with the upstream and downstream pipeline system. In addition, sacrificial anodes might be used at specific locations.

4.7 CONSTRUCTION

This subsection provides an overview of the construction plans for the new compressor units, including:

construction procedures and execution safety inspection and monitoring

Information on the compressor construction workforce, as well as the likely construction timing and sequencing, is also provided.

The information in this subsection is based on preliminary planning. Construction plans will be further developed during detailed design and will incorporate input from the selected construction contractors.

4.7.1 Construction Strategy

At this stage in preliminary design, TransCanada plans to hire prime contractors to complete site clearing, rough grading, fabrication and main construction of the compressor unit additions.

4.7.2 Construction Contracts

The prime contractors for compressor unit additions construction will be chosen through a formal bidding process once detailed design is complete.

Separate contracts will be awarded for work outside of the scope of the construction contracts, such as construction surveying and NDE testing.

4.7.3 Construction Procedures and Execution

TransCanada will use conventional construction methods and industry best practices when constructing the compressor unit additions. Construction activities will include:

conducting pre-work for clearing surveying clearing removing upper surface material, and salvage, where required grading piling installing foundations installing compressor buildings and units installing generators installing auxiliary buildings and equipment piping and pressure testing conducting electrical work

PDF of 37




installing the instrumentation system installing controls commissioning conducting pre-startup safety review conducting final site cleanup

Construction will be done in accordance with the applicable TransCanada specifications, standards and operating practices, and with the Compressor Station EPP as provided in the ESA.

4.7.4 Security Management

TransCanada’s corporate security policy and programs are aligned to CSA Standard Z246.1 for security management.

During construction of the Project, security management will be governed by those policies and programs, and through a TOP that govern construction security. The TOP details TransCanada’s security expectations and plan elements for the prime construction contractors on the Project. TransCanada will audit the prime contractor plans to ensure compliance with the TOP.

Consistent with this standard, ongoing security assessments will be conducted and documented, and security management plans will be developed and implemented for the Project.

The TOP will also be used to govern security management during the operations phase.

4.7.5 Construction Safety

During construction, the prime contractors will have overall responsibility for health and safety at the work site. A Project-specific construction SMP will be developed and implemented. The SMP outlines key safety guidelines for the prime contractors to use when developing their SSSP so that a collaborative commitment to Project safety is achieved.

TransCanada will review each prime contractor’s SSSP before construction to ensure compliance with company and regulatory requirements. The prime contractors will also prepare a security plan and ERP. These will be reviewed by TransCanada before construction starts. The SMP, SSSP and ERP will be included in site orientations and copies will be made available onsite for the duration of construction.

Qualified construction managers will be appointed to fulfill the requirements of the construction safety program. The construction managers will be authorized to halt any construction activity if the work is not being performed in a manner that meets all applicable safety policies and standards.

PDF of 37




Where required, the construction managers will coordinate obtaining all safe work permits, and all personnel will be required to complete a contractor safety orientation before working on the work site.

Safety requirements will include a daily safety meeting (or meetings), led and documented by the prime contractors, as well as the use of incident reporting forms and procedures that will include near-hit reporting. Where required, a detailed incident report form from the OPR will also be completed. TransCanada will inspect or audit the prime contractors to ensure strict compliance with the SMP.

For additional safety information during operations, see Section 5.1.2: Health, Safety and Environment.

4.7.6 Construction Inspection

Construction of the compressor unit additions will be supervised and inspected by qualified TransCanada construction inspectors to ensure compliance with all applicable regulations, standards and codes, and with conditions on regulatory authorizations. Inspection staff will be onsite during the entire construction period.

4.7.7 Construction Schedule

The construction of the compressor unit additions is expected to take about 10 to 12 months per station. Subject to regulatory approval, the main construction of the proposed compressor unit additions is proposed to begin in Q2 2016 and be complete by the end of Q1 2017.

4.7.8 Construction Resources

The construction of compressor unit additions will require resources with various skills, ranging from entry-level labourers to highly skilled trades and supervisory personnel. During construction, each station will require about 50 to 150 personnel at one time.

4.7.9 Construction Camps

Construction camps are not required for the compressor unit additions as local accommodations and services will be used for the workers.

4.7.10 Access Plan

Existing access to each of the five sites will be maintained and expanded as required for the compressor unit additions. The access roads will also be used during construction.

PDF of 37




4.7.11 Quality Management

TransCanada will provide technical oversight for pipeline engineering and technical activities, and will also ensure coordination with prime contractors and other third-party engineering consultants to ensure that TransCanada’s engineering specifications are met.

All purchased items and contracted services will be obtained from suppliers and contractors that have been pre-qualified in accordance with TransCanada’s internal supplier management and pre-qualification procedures.

Moving into construction, the prime contractors will be responsible for ensuring the work being performed is in accordance with contract documents, the project design, applicable standards, specifications and procedures, and will comply with the project-specific quality plan. Inspectors will monitor activities, such as site mobilization, excavation, piling, welding, backfilling and grading, to ensure compliance.

Design changes during construction are managed in accordance with the appropriate change management procedures and in accordance with TransCanada’s standard engineering practices.

4.7.12 Joining Program

All welding and NDE testing of welds will be conducted in accordance with the requirements of CSA Z662-11, the OPR, and the welding procedures and specifications in Table 4-4.

The prime contractors will conduct welding in accordance with the welding procedures provided by TransCanada. Fabrication and assembly of welded pipe spools will take place at the contractor’s fabrication shop and final fit-up welds will be done at the site. TransCanada will hire an independent third party to conduct the NDE on all welds required for the Project.

4.7.13 Nondestructive Examination

For all high-pressure gas piping designed to CSA Z662-11, TransCanada will use 100% NDE coverage. For all other piping systems, TransCanada will select material and designs joints in accordance with ASME B31.3-2010, Chemical Plant and Petroleum Refinery Piping, as referenced in Clauses 4.14.2.11, 5.1.1, 7.2.4 and 8.1.7 of CSA Z662-11. TransCanada will ensure that joints are examined in accordance with Clause 7.10.3 of CSA Z662-11.

The NDE for facility piping will be carried out in accordance with TransCanada specifications TES-WELD-AS and TES-NDT-RT and, where applicable, TES-NDT-UT2. All butt joint welds will be inspected visually and radiographed or

PDF of 37




ultrasonically tested for 100% of their circumferences. All fillet welds are to be inspected for 100% of their circumference using magnetic particle inspection or, for non-magnetic welds, a liquid penetrant inspection process.

For lower-risk auxiliary piping systems, TransCanada proposes to conduct NDE on 15% of production welds per day during construction. This conforms to CSA Z662-11, Clause 7.2.5, and would not compromise the safety of the public or company personnel, nor would it affect the company policy of ensuring that all piping is pressure-tested before being placed into service.

For the auxiliary systems that are being proposed for 15% NDE coverage, see Table 4-6. These systems operate at low stress levels and, generally, have instrumentation that shuts down the system and limits any leaks if a release incident occurs.
