The challenges

As the BAE Systems site was a high security site, Adroit had to work closely with key security personnel to ensure the project was delivered in a timely manner this involved having all staff vetted and security cleared to an MOD standard.

During the installation of the pipeline we had to work closely with the electric DNO as a new high voltage (HV) system to a substation was also being installed, in addition to the above there was an existing railway line that crossed the route of the proposed pipeline. After consultation it was decided that the best course of action was to install the pipeline under the railway track which the onsite team were able to overcome.

All work was completed despite the above and to the satisfaction of the client.
