Inefficient actuators upgraded to Rotork intelligent electric actuation at a water adventure site

IQ3 actuators from Rotork have improved and modernised the flow control system at a white water centre in the north-east of England, UK.

The Tees Barrage International White Water Centre is an activity and sports site. Visitors can go white water rafting, canoeing, kayaking, power boating and paddleboarding.  It is part of the Tees Barrage Park visitor attraction situated on the River Tees at Stockton-on-Tees. 

Opened in 1995, the Tees Barrage was built to provide for the development and improvement of the area and recreational use of the River Tees by maintaining an upstream river level.  It is looked after by Canal & River Trust who are undertaking a project to help to improve the performance of the existing control system.

The penstocks on site feed the water course with river water, prevent seawater from entering the park at high tide (seawater is undesirable for white water users and will lead to equipment corrosion) and maintain water levels into the park to prevent it from flooding in extreme weather conditions. The old control system was hydraulically operated and was proving unreliable. It was provided by linear hydraulic cylinders and a single hydraulic power pack without torque protection, no data or condition monitoring and limited position feedback. This caused broken penstock spindles, oil leaks and needed unplanned maintenance intervention. The existing power cabling had insufficient capacity to supply five actuators and required updating to comply with the latest regulations.
