Featured Project

Coleson Cove 900 MW Thermal Plant Upgrade

During the Coleson Cove 900 MW Thermal Plant upgrade project, Lorneville was hired by NB Power to design, fabricate, and install a new Flue Gas Breaching System.

For this project, Lorneville utilized fabricated modules to gain efficiencies in field construction activities, and with efficiency knowledge, we fabricated large modules in our shop. This fabrication project included:

Six units, 150ft long x 21ft in diameter x 140 tonnes
Eight units, 110ft long x 21ft in diameter x 110 tonnes
Twelve units, 60ft long x 21ft in diameter x 40 tonnes

After the design and fabrication of these modules in our Saint John, New Brunswick fabrication facility, we shipped the modules to the thermal plant in Coleson Cove for installation by our team. This project was a massive success, as we were able to apply a unique approach to rigging that allowed us to position large components beyond the reach of cranes. This method was a critical factor in the success of the project—a testament to Lorneville's commitment to delivering the most efficient and effective approaches to fabrication and installation.
