Brunswick Lock Gates, Liverpool

Client:Morrison Construction Ltd (British Waterways)
Value:£1,000,000
Location:Liverpool

Working on behalf of client Morrsion Construction Ltd and British Waterways, Amco completed a half life maintenance overhaul on the Brunswick River Entrance Lock Gates.

The river entrance is a tidal lock, controlled by two sets of quadrant gates, which provide access from the River Mersey to Brunswick Lock and Liverpool Marina.

The contract required multidisciplinary mechanical, electrical and civil engineering input and fully utilised the vast array of experience within Amco's directly employed multiskilled workforce.

The plant and equipment at the river entrance was installed in 1987 and has a design life of 40 years.  This 20 year half life overhaul consisted of the removal, refurbishment and re-installation of the lock gates, a bascule bridge, penstocks and silt dispersal systems.  The works also included a full upgrade to the hydraulic operating system and an uprating of the electrical control system.
