Blenheim-Gilboa Vertical Shaft Inspection

Blenheim-Gilboa - Inspection Pre-visualization
Project Overview: 
McLaren was retained to perform an inspection of the Dewatered Vertical Shaft and Elbow at the Blenheim-Gilboa Pumped Storage Power Project. The inspection included visual and partial “hands-on” examination of the upper reservoir intake structure, the vertical shaft and the transition elbow, in order to categorize any new or previously identified deficiencies and to provide repair recommendations and cost estimates.
McLaren's Role: 
Due to the unique nature of this project, McLaren’s team of engineering and surveying specialists developed special procedures for measuring and mapping elements of NYPA’s system. This required the design and fabrication of an equipment package capable of photographing and measuring the shaft over its 1000 foot depth. McLaren, responsible for overall project management, also developed a conceptual design of an equipment package capable of facilitating the inspection of the vertical shaft and transition elbow. The design and fabrication of this rigging system allowed for proper movement of the camera equipment to facilitate the inspection of the 28-foot diameter vertical shaft and transition elbow's internal surfaces.
