Briggs Marine divers and support vessel at work

As part of the ongoing Woolwich Ferry project, a detailed survey of the river bed was undertaken by our client - Briggs Marine.

To enable this Robert West specified the survey method - that of using the Port of London Hydrographic Department state of the art geo-physical equipment combining multi-beam sonar and a 3D chirp.  This enabled the plotting of detailed bathymetry which located the top of the chalk strata, submerged structures and debris including potential unexploded ordnance (pUXO) resting at, or just below the river bed by identifying  objects which were acoustically different from the surrounding medium.

Briggs Marine’s Diving Division then investigated each anomaly identified which determined that these were not UXOs. The divers then proceeded to remove the various obstructions and debris  from the river bed.

The results were used as evidence to secure an As Low As Reasonably Practical (ALARP) certificate prior to commencement of construction.
