Flood control penstocks at a major UK reservoir have been automated with the design and installation of new actuators and gearboxes as part of an extensive upgrade programme. The end user wanted to automate the existing manually operated penstocks to provide reliable and fast operation in severe weather conditions. In a contract awarded to Score Europe by WA Cooke engineering, Score undertook the design and automation while WA Cooke serviced and repaired the penstocks. WA Cooke was appointed as the Lead Contractor.
Score’s work included calculating the 100-year-old penstock operating requirements and power consumption to deliver reliable 24/7 operation. The improvements deliver fast and reliable flood control, opening the penstocks and moving water from the upper reservoir to the lower reservoir on demand, providing the operator with the maximum reliability and availability on this application.
Score designed, engineered, and manufactured the penstock automation solutions and selected Rotork’s IQS actuator for this project which offers high levels of reliability and environmental protection. The actuators were mounted to bevel gearboxes and supplied with vandal proof covers to stop unwanted operation of the penstocks in this remote location. Work also included the design and installation of power supplies and extensive on-site machining to modify the manual penstocks for automation.
Score engineers dismantled the existing manual pedestals, engineered and replaced worn and obsolete components as required, and manufactured custom adaptions before installation of the actuators and gearboxes. The finished installation was inspected and signed off ahead of schedule to the satisfaction of WA Cooke’s Project Director. All work was carried out by Score’s fully qualified site service engineers according to Score’s own site safety procedures and regulations.
