Great Britain has been hit several times in the past decade by severe flooding, which in addition to nuisance for residents also caused considerable material damage. TEAM2100 is the Environment Agency’s 10-year programme to refurbish and replace tidal flood defences in London and the Thames estuary. TEAM2100 will carry out the first part of the Environment Agency’s Thames Estuary 2100 Plan, which sets out how to manage tidal flood risk in the Thames estuary throughout the 21st century.
Tilbury Dual Function Lock Gates-project
The Tilbury Dual Function Lock Gates project, delivered via TEAM2100, is a major joint project between the Environment Agency and The Port of Tilbury to replace that will safeguard thousands of homes and businesses in the local area. The existing port lock gates will be replaced with pioneering dual function lock gates, and the Environment Agency’s tidal barrier will be removed. Once the work is completed it will ensure a high standard of flood protection for Tilbury and provide a new navigation lock for operations at the busy port.
Pioneering dual function lock gates
In 2019, Hollandia Infra was approached by Balfour Beatty to make six new lock gates for the UK’s Rijkswaterstaat Environment Agency (EA) at the Port of Tilbury. The replacement of the lock gates is part of the TEAM2100 project, where the EA wants to manage the risk of flooding in the mouth of the River Thames until the year 2100. The double-acting barrier in Tilbury will consist of 6 steel gabled doors. Hollandia Infra supplies a total of 6 steel pointed doors with the pivot bowls and neck brackets for this new storm surge barrier or lock. The doors will be placed in 3 sets of 2 doors, with the 2 outer doors on the Thames side also having a reversing function. These 2 “outer gates” are therefore provided with “barriers”. They use this to stop the water from the Thames in case of high water.
What is happening on the Hollandia Infra site
The actual contract was signed in 2020. Our work consists of manufacturing the 6 lock gates for the Port of Tilbury. First, we started making an executive design and preparing for manufacturing. In the meantime, the manufacturing design for our delivery of the 6 lock gates for the Port of Tilbury has been largely completed and we started production of the two middle doors in mid-March. We manufacture the doors in 3 sets of 2 doors. We make, as indicated, first the middle, then the inner, and then the outer doors.
