KITIMAT, B.C. — The Coastal GasLink project team has broken ground on the pipeline’s Kitimat Meter Station.
The station is one of two compressor and metering stations that will become the anchor points of the natural gas pipeline.
“This important milestone was made possible thanks to the District of Kitimat’s close partnership and support,” said the project team in a statement. “Together, we are proud to be part of B.C.’s healthy economic recovery.”
According to Coastal GasLink, compressor stations are needed because as natural gas flows along a pipeline, it slows due to friction with the pipe, resulting in a drop in pressure. To keep the gas flowing at a required rate, it is repressurized at locations along the pipeline. This is done by mechanically compressing the gas at sites connected to the pipeline, known as compressor stations.
The locations of these stations are chosen by analyzing the operating pressure of the pipeline, the diameter of the pipe, elevation changes along the pipeline route and the volume of gas transported.
Depending on future decisions about increasing the pipeline’s capacity, the project could eventually add seven compressor stations.
The meter station will also measure the amount of natural gas that enters and exits the pipeline. Meter stations ensure that the natural gas in the line meets required specifications. These stations are used at all locations where natural gas enters the pipeline or leaves the pipeline.
When complete, Coastal GasLink says its pipeline will deliver at least 2.1-billion cubic feet of natural gas everyday to a LNG Canada liquefied natural gas facility being built in Kitimat.
