3 Hydraulic Design The followin g sectio ns describe th e detailed pipeline and related facilities require d to achieve the desired th roughput for the pipelines describ ed above in Section 2.1 : Background.

For design purposes, the following capacity definitions are required:

• Design Capacity - Maximum theoretical capacity of the pipeline assuming ideal operating conditions, which mayor may not be achievable in actual operation.

• Operating Capacity - Sustainable average capacity re suIting from ta king into account un -planned e vents such as un- scheduled maintenance, operating problems, leaks, varia tions from forecast, an d schedulin g proble ms (95% 0 f Design Capacity).

• Annual Average Capacity - Sustainable average capacity on an annu al basis taking into account planned eve nts such a s schedu led maintenance and construction (90% of Design Capacity).

The following design philosophy represents Enbridge's typical appr oach for pipeline design. Thermal effects can playa large role in determining the achievable capacity of a pipeline, especially in heavy crud e lines where frictional heating ca n contribute to a significant increase of in-line crude temperat ures. With a n increase in temperatu res there is a decrease in fluid visco sity resultin g in lower pressure dr ops and highe r predicted capacities. Therefore, these effect s must be taken into account when completing a hydraulic design.

Enbridge's design philo sophy invol ves two steps. The first step involves solving an energy balance where the frictional heating generated by the annual average capa city, and the flu id heat tran sferred to th e soil durin g annual average conditions, deter mines the resulting in-line fluid temperature profile.

Secondly, the temperature profile created at the annual average capacity is force don the pressure drop calculations at t he design rates, resulting in a conservative pressure drop calculation at the design capacity due to the realistic th ermal profile created at t he annual average capacit y. Impleme nting this philosophy reduces the possibility of over estimating the design capacity of the pipeline.

For the detailed ste ady state hydraulic design r temperatures, and power) please refer to Appendix E.

Since both the oil and the diluent pipelines are large diameter pipelin es with relatively large motor sizes, BDE Hydra ulics recommends the use of a Variable Frequency Drive (VFO) to enhance operability and reduce pressure throttling.

3.2.5 Case Pressure Limits


?J N RIDGE

For crude oil pipeline pump stations, all the st ation piping will be designed to PN 150 (ANSI 900) class resulting in a case pressure limit of 2160 psig for all pump stations. To maintain maximum operational flexibility, it is recommended that all the station piping be hydro-tested to the full ANSI 900 (2160 psig) rating


For condensate pipelin e pump stat ions, Clearwater, Fort St. James, Be ar Lake, Smoky River, and Whitecourt will be designed to PN 150 (ANSI 900) cia ss resulting in a case pressure limit of 2160 psig for these 5 stations. All the other stations will be designed to PN 100 (ANSI 600) class resulting in a case pressure limit of 1440 psig.


(A39833)





3.2.6 Pump Standby

The current Enbridge standby philosophy is to ensure that when the largest unit at a pump station is out of service, the pipeline can still achieve operating capacity (95 % of design capacity). A sta ndby analysis was com pleted to en sure the pro posed desig n for the NGP meets the above criteria. The results are summarized in this section.

3.3 Operational Limitations and Concerns

3.3.1 Petroleum Quality and Batching The oil and condensate pipelines were hydraulically designed based on a single product for each pipeline. During detailed engineerin g, the final hydraulic design for t he oil pipeline will incorporate the additional lighter oil products anticipated to be transported in batches, a nd this will re suit in revis ions to the design pressures and wa II th icknesses at some specific locations along the pipel ine.

3.3.2 Minimum Reynolds Number

The table below summarizes the range of the Reynolds number in any crude oil pipeline and condensate pipeline at in itial and ultimate flow rates. It can be seen that the flow regime is fully turbulent in both system at the target flow rates.

Pipeline Phase Design Flow Rate (bpd) Reynold's Number

I 583,333 4,531 - 5,395 Oil

IV 944,444 9,763 - 25,082

I 214,111 803,725 - 824,213 Condensate

III 305, 556 1,179,335 - 1,240,192

3.3.3 Maximum Mainline Fluid Velocities

The maxi mum fluid velocity in the crude oil pipel ine is 9.5 ftlsec ba sed on the ultimate phase targe t design ca pacity of 944,444 bpd. The ma ximum fluid velocity in the condensate pipeline is 9 .7 ftlsec based on the ultimate phase target design capacity of 305,556 bpd. These values are within the typical flu id velocities found acceptable on the Enbridge System.

The temperature profi le shown above indicates that the maximu m in-line temperatures between Bruderheim and Kitimat range from between 19.3°C (66.8°F) and 39.SoC (103.1°F) at the Pha se I flow rate; 38.1 °C (100.S0F) and 40.9°C (1 os. rF) at the ultimate flow rate. These in-line temperatures are well within the desig n limitation of the pipeline SO.O°C (122.0°F).

3.4.2.2 Sensitivity Study

There is so me uncertainty in some of the thermal assumptions u sed in determinin g the baseline thermal profile shown above, specifica lIy soil prop erties (ther mal conduct ivity and temperature). Th erefore a sensitivity analysis was conducted around th ese parameters to determine the range of potential maximum in-line temperatures that could be seen.

Sensitivity Assumptions:

• Summer soil thermal conductivity -lower by 30% from the values in AMEC report (200S) based on previous project experience.

• Summer soil temperatures - 10°C (SO°F) based on preliminary reCD mmendations provided by Derick Nixon (2008).

The in-line temperature profiles of the above two sensitivity runs are presented in the graph below, together with the baseline profile for the purpose of comparison.

Note: This is a preliminaIY DRAFT (v3.6 dated August 23, 20 II) aIld has been issued for information only. It has not undergone a rigorous review by internal stakeholder groups.

The results show that th e maximu m temperatures are arou nd 40.0°C (1 04.0°F) in most cases. However, it can get close to 50.0°C (122.0°F) when the soil co nductivity is 30 % lower than the AMEC re port values, It is recom mended that an addition al soil sampling program be conducted at the commencement of detailed engineering.

4 Transient Analysis A preliminary transient analysis ha s been conducted for both the crude oil pipelin e and the condensate pipeline systems

4.1 Crude Oil Pipeline System Thirty-eight (38) scenarios in tota I were ex ami ned for the oil pipeline system at the ultimate flo w rate. The transient scenarios examined include sudde n and unplanned pressure co ntrol valve (peV) closure (95% at intermediate stations, 1 00% at delivery locations), station suction valve closing, and station lockout.

The transie nt study resulted maxi mum pressure profiles of all scenario s, as well as the steady-state pressure profile are sho wn in the figure below. I t can be seen that the wall thickness design is adequate as the maxi mum pressure profile of all scenarios is under the 110% MOP limit.
