CGR was commissioned to undertake wharf condition surveys at United Marine Aggregates’ wharf facilities at Murphy’s Wharf, Charlton and Pioneer Wharf, Erith on the River Thames. The site at Charlton is Europe’s largest marine aggregates terminal and handles over 1.5 million tonnes of dredged aggregates per annum. The dredged aggregate is barged to the site and discharged at the wharf for processing and sale. The marine infrastructure associated with these facilities is therefore very important in ensuring smooth ongoing operations at the plants.
The facilities included within the scope of the survey included the berthing and mooring dolphin structures, the deck fittings and fixtures, the piles, the access walkways and the conveyor support infrastructure.
The work included above water inspections in combination with underwater inspections and non-destructive testing of the steel piles. The reports provided a catalogue of the current condition of the marine facilities at each site including photographic records of the facilities. Recommendations for maintenance to ensure the longevity of the facilities were also included within the reports.
CGR was involved in the implementation of the recommendations.
