A modular platform developed for Hydroelectric Turbine Maintenance
Sigma Design solved a very unique problem for the clean energy industry. We developed and manufactured a modular, 26 foot diameter maintenance platform for Hydroelectric Power facilities to service the underside of vertical power turbines. This presented a unique challenge, as all of the pieces of the platform had to be passed through a 24” x 30” manway. Sigma designed a platform that could be broken down into much smaller sections, taken into the turbine area, and assembled by a small crew. This required Sigma to complete detailed assembly instructions, and also assemble and load test it in-house.

Services Performed: Structural analysis and design, large structure fabrication, load testing, work instruction drafting, assembly, test and analysis.
