Lough Neagh

The Background

Lough Neagh is the largest lake in Ireland and the UK, with a surface area of 151 square miles, it supplies 40% of Northern Ireland's water. Numerous rivers flow into the lake, which in turn discharges to the sea via the Lower Bann River. The Lough Neagh catchment drains 43 percent of the land area of Northern Ireland, as well as some border areas in the Republic of Ireland, with sluice gates at each location spanning the River Bann regulating the water levels, keeping them within a defined range.

After years of use, the sluice gates at Toomebridge, The Cutts Coleraine and Portna required the replacement of their entire hoist conductor systems. The works, delivered by WH Scott & Son, included the removal of the existing hoist conductor system and supply, delivery, off-loading, installation, testing and commissioning of the replacement system.

The Project

To ensure the safe removal of the systems and installation of the new equipment, we subcontracted Houtman Scaffolding for the design, supply, delivery, off-loading, erection, dismantling and removal of the scaffolding system at each location. A safety boat was also provided by the client, The Department for Infrastructure, Rivers Agency, at each location for the duration of the works.

Working with Simbal we produced a system using the Mobilis Elite enclosed conductor system, the hoists which travel across the steelwork at the locations across Lough Neagh were supplied with two three-phase, 400 volt, four pole electrical power via a continuous busbar system, compatible with the existing hoists and trollies.

The project was completed on time with a 100% safety record.
