Hedley Hydraulics Limited in the UK has provided the Hull Flood Barrier Defence system operated for the UK Environmental Agency with a complete integrated pipe work installation and bund arrangement as part of the facilities upgrade to a hydraulically control. Hedley needed to install the pipe work alongside a multi-disciplined team of suppliers for this project working to tight delivery schedules to ensure that the Flood Barrier was operational with the minimum downtime period. 

The integration of the pipe work system by Hedley Hydraulics needed to be to exacting standards, time based and closely project managed. Working closely with the Mechanical & Engineering Design authority, the Hydraulic Power Unit supplier, and Civil contractor; Hedley Hydraulics ensured that the pipework installation and bund arrangement went to pre-agreed deadlines. 

With some 1200 meters of hydraulic pipe work installed and a bund holding capacity of 1200 litres of oil should a system failure occur; the Environmental Agency were insistent that no hydraulic leaks should be capable of entering the Humber Estuary resulting in damage to local marine wildlife and the fragile ecosystem in the area. Hedley incorporated into the project Parker’s EO Form, high pressure formed tube system, designed to eliminate leakage when used in fluid systems.  

The project was taken in stages, with a full ‘mock up’ of the installation taking place outside Hull, to ensure a smooth transition prior to carrying out the actual installation within the Hull Flood Barrier. Work on the barrier was challenging, all products had to be lifted into place at the top of each tower, Hedley utilised a 3-Dimensional design package to ensure that the design of pipework fully integrated within the building, HPU supplier and of course the structure of the building.  

John Massey, Director of Hedley Hydraulics said ‘the installation of the pipework and bund arrangement was a challenging project, delivering a solution, within a tight timeframe, within a multi-disciplined team was of paramount importance, we are proud of our achievements for the City of Hull and our customer.'
