Year:

2003

Royal Haskoning was commissioned to carry out a condition survey on the underwater elements of the Woolwich Ferry crossing the River Thames. The underwater inspection was part of a multidisciplinary structural inspection of the entire berthing facilities servicing the ferries. 

The underwater survey included the piled approaches with timber fendering, berthing dolphins, walkways and lifting towers. The structures were inspected below water using a diving engineer from Royal Haskoning’s underwater services section. 

The structures were found to be in a reasonable state of repair for a structure of this nature and future maintenance recommendations were included in the final report.
