JCB Excavators Retrieve Wreckage From Swansea Sea-Bed

Pictured are two JCB tracked excavators working on the sea bed at Swansea Docks retrieving the remains of a dilapidated vessel on behalf of specialist demolition and waste contractor, Stenor Environmental.

The hull of the vessel believed to be a cargo ship which ran aground approximately 70 years ago has been entrenched in the sea-bed alongside the sea wall but has now begun to break up. As this poses the risk of debris floating into the main shipping channel, Stenor has been commissioned to demolish and extract the remains.

The project involved the dismantling and handling of approximately seventy tonnes of partly corroded metal over two days using the JCB JS220 and JCB JS 330 tracked excavators fitted with cutter crusher attachments. However, it was complicated by the fact the ships wreckage was only accessible at low tide and was situated well below the sea wall. This required a ramp to be built out of recycled aggregates allowing the excavators to reach the sand and return with the extracted materials during a narrow four hour tidal window.

Stenor Environmental Owner, Steve Norman said: The job was an urgent and extremely technical one, requiring detailed preparation. The influence of the tides meant we needed to be as efficient as possible. The accuracy, power and performance of the two JCBs made them extremely productive despite the tough working environment. They contributed greatly to the successful completion of the project.
