S&B Infrastructure Private, Ltd. (S&BI) is tasked with the FEED Study and detailed design of the Seaway II Pipeline project (a joint venture between Enterprise and Enbridge) facilities. The pipeline will deliver crude oil from Cushing, Oklahoma to Seaway’s Jones Creek Station for ultimate delivery to the Houston Area refineries. The project involves the following stations:

 

Origination Station:

 

The Origination Station will be located on Enbridge’s Cushing site.  Provision shall be made for connection to Enbridge, Plains All American, and various other shippers.

 

• All incoming crude will be measured by one of two incoming custody transfer quality meter banks. Each meter bank will be tied to a common bi-directional meter prover. Each meter bank will include a sample loop piped to a Sample Building.

• A pump header shall run from the sample loops to three 6,000 HP mainline pumps, installed in series.

• The mainline pump discharge shall be piped to PIG launcher and a tie-in to the Pipeline.

• The project involves the installation of two Sample Buildings, a Lab Building, an Office Building, and a building to house the switchgear, motor control centers, PLC, HMI and SCADA communications hardware.

 

Intermediate Pump Stations:

 

The project includes the design of nine intermediate pump stations along the Pipeline route.  Each pump station will include a connection to the new Pipeline at both the entry and exit from the station.  Each station will include a station bypass, pressure control station, strainer, and three 6000 HP mainline pumps, installed in series, and a new building to house the switchgear, motor control centers, PLC, HMI and SCADA communications hardware.

 

• The North Seminole Pump Station, Corsicana Pump Station, and Singleton Pump Station will also include a connection to the existing Seaway 1 Pipeline.

• The existing Colbert and Cedar Pump Station will be expanded to include the three mainline pumps, a PIG launcher, a PIG receiver, and an ultrasonic leak detection meter.
