Case Studies
Proven results across critical infrastructure.
Engineered, code-compliant solutions delivered safely—without taking assets out of service.
Featured Case Study
In-service composite repair of high-pressure energy infrastructure
Client
Con Edison
Facility
Transmission Distribution System
Location
New York, NY
Challenge
Aging high-pressure fluid-filled dielectric electric feeders experiencing corrosion and leak risk. Traditional refurbishment requires welding a custom-fabricated new pipe over the existing feeder—a significant capital expenditure.
Solution
IIS engineered and deployed a composite refurbishment system designed as a secondary pressure boundary, compliant with ASME PCC-2 and utility engineering standards.
Execution
Engineering analysis, design and testing validation, QA/QC and nondestructive examination, in-service installation with zero downtime.
