Project description

Project title

Project background

To ensure continued operation of a Sea Water Cooling System, BAE Systems is required to remove up to 20,000m3 over a ten year period of silt build up in and around the sea water intake and from the wet well at the test facility (A 31) Barrow in Furness.
There are four components of the project:

1) Clearance of silt from the vicinity of the intakes up to 14,000m3
2) Perform an intake pipe clean to remove up to 4,000m3 of silt from within the intakes;
3) Clearing out the wet well of up to 2,000m3 of silt;
It is anticipated in each dredge campaign to remove the build-up, which is threatening the abstraction of sea water used for the cooling of industrial combustion process in two to eight weeks using an air lift for the removal tasks. The dredge material from the activities is to be disposed of into the tide.

Programme of works

Over the 10 year license period BAE will require to hot commission the Main Combustion Plant requiring Sea Water Cooling during each campaign in preparation for full operation of the Combustion Processes. We would arrange for silt removal in the first campaign as soon as possible in 2020/2021 to support the commissioning trials, and works will occur over a 2 - 8 week period where between 50 and 100m3 of marine sediment will be removed per day and dispersed into the tidal flow.
The clearing of the seawater intake pipes and the wet well clearance will also utilise air lift techniques and pumps over a period of up to 5 weeks per campaign.
