37 New Wind Turbines for New York

37 New Wind Turbines for New York

This project involved the installation of 37 new wind turbines at Cassadaga Wind Farm, Buffalo, New York, resulting in a total renewable energy capacity of 125.5 MW.


Wm. O’Brien was responsible for the:

– Project management of all heavy lift activities

– Crane hire

– Personnel hire and supervision

– Liaison with local Iron Worker and Operator Unions

– Contract negotiation and management of equipment suppliers

– On site management and supervision of all lifting equipment

– Engineering and lift drawings

– Hard stand drawings and layout plans

– Component transport prioritization

– Obtaining Professional Seals and Certifications for State-level compliance of lift plans and drawings


Weather proved to be a major challenge on this project, from snow and sub-zero temperatures to high winds and heavy rain. To best manage an uncontrollable situation, flexible work times were arranged to suit weather windows and reduce standing time on site.


As part of the overall scope, Wm. O’Brien was responsible for the movement of the Liebherr LG1750 Lattice Cranes which were relocated safely and within the required timeframe between hard stands despite weather conditions. This fast turnaround helped to maximize lifting time, minimize downtime, and reduce client costs.


A total of 30 Wm. O’Brien staff were involved including a site manager, site supervisors, crane operators, truck drivers, iron workers and oilers.
