Upstream Pipelines

Lanmark provided engineering, design, regulatory, and procurement services for the construction of a 12″ OD natural gas pipeline installation in the Pembina and Brazeau River areas of Alberta. To achieve cost savings, Lanmark also led the installation of a partial 12″ OD natural gas gathering line that shared the same trench.

Project details:

• 18.9 km, 12″ mainline pipeline

• 3.0 km, 12″ gathering pipeline

• Intermediate Camelback risers with provisions for future launcher/ receivers

• Cathodic protection test stations

This project involved doubling the capacity of a Foothills sour gas system through the effective utilization of hydraulic modeling and process engineering.

Lanmark completed project management, mechanical design, civil design, and materials sourcing for the project.

Project details:

• 16 km of 8” OD sour gas pipeline and 32 km of 3” glycol subsurface heat trace pipeline loop (design temperature 60 °C)

• Retrofit of three (3) compressors and relocation of gas blending facilities

• Designed and strategically installed line heaters along the pipeline route

Lanmark provided project management, engineering, design, regulatory, and procurement services for the construction of a mult-line pipeline installation. The pipelines were used to transport 111 MM scfd of gas and 1,000 bbl/day of condensate.

Project details:

• A major crossing of the North Saskatchewan River with a bore length of 2.4 km; one of the longest river crossings in Western Canada

• 16” Sales Gas pipeline

• 8” Fuel Gas pipeline

• 8” Gas Gathering pipeline

• 4” Condensate pipeline
