The Challenge: Replacing a Critical Hydraulic Component Without Compromising Operations
The replacement of Emergency Spillway Gate 2 required intervention on an essential dam safety structure within an active hydropower plant.
The primary challenge was to execute the removal and installation of a major hydromechanical component while maintaining structural integrity, controlling water levels, and ensuring worker and public safety. The project also required tight sequencing, specialized lifting operations, and full compliance with applicable hydraulic and safety standards.
In projects of this nature, precise planning, proactive risk management, and strong coordination between engineering, field crews, and stakeholders are critical to ensuring performance and long-term reliability.
Intervention by Equinox Construction Services
Our team ensured the detailed planning of work sequences, coordinated specialized subcontractors and suppliers, and supervised both the removal and installation of the gate. Throughout execution, we maintained strict quality control and regulatory compliance while proactively managing site-related risks.
To support the intervention, comprehensive technical documentation was developed, including site-specific work methodologies, lift plans and safety procedures, hydraulic control sequencing, as well as inspection and commissioning reports.
Upon completion, Emergency Spillway Gate 2 was fully operational, restoring the safety and reliability of the hydraulic control system.
