Featured Projects

Coal Fired Power Plant

BISI completed the demolition and replacement of 250 Soot Blowers throughout three 550MW IK units at a coal fired power plant near Wheatland, Wyoming. The boiler units remained online during construction allowing for zero downtime. The project was executed with zero QA/QC issues or safety incidents.

Unit 3 & 4 Turnaround

BISI performed a plant turnaround on units 3 & 4 at a refinery located in Torrance, California. The scope of work involved the disassembly, repair and re-assembly of exchangers and fin fans. The work was performed in high pressured units, and was completed with zero QA/QC issues or safety incidents. BISI employed local boilermakers and craftsmen through the local union hall. The utilization of local resources allowed for a quick and efficient turnaround.
