Imperial Wharf

Design and Installation of a Cathodic Protection System

Gravesend, Kent
4 months


  • Survey of piles
  • Fabrication and installation of anode assemblies


Imperial Wharf is an operational facility used for the import of bitumen into the UK. This was a vital asset that could not be allowed to remain out of service for any length of time.

DiveCo Marine were awarded this contract following a tender process involving three other contractors.

As an established diving contractor with highly skilled, specialist and qualified personnel, our size, capabilities, and proximity to the site, we were ideally placed to support this client’s requirements.

This project comprised a full design and installation package, of a cathodic protection system to the client’s jetty in Gravesend. The objective was to reduce the risk of accelerated low water corrosion to the supporting steel pile legs. Without this protection, the jetty steel legs would have corroded quickly, resulting in the facility having to be relocated at great expense, whilst a new jetty was constructed.

These works have halted the accelerated corrosion and significantly increased life expectancy of the asset. In addition, we have been engaged to periodically monitor corrosion levels, and to assist with any future maintenance requirements to the jetty.
