Celebrating the Completion of Portsmouth Harbor Dredge

Britain’s Defense Minister Harriett Baldwin is set to announce that millions of meters of mud have been dredged, clearing the way for Britain’s newest aircraft carrier to sail safely into her new home at Portsmouth Harbor.

The Defense Infrastructure Organisation (DIO) awarded a contract to Boskalis Westminster to make room for the 65,000-tonne HMS Queen Elizabeth Carrier and her sister ship Prince of Wales two years ago.

Since then, specialist dredging vessels have been at work, removing 3,200,000 cubic meters of sediment – the equivalent to 12,800 Olympic swimming pools. During the dredging of the approach to the harbor, more than 20,000 items have been found in the area, many dating back several centuries.

Defense Minister Harriett Baldwin said: “The work to prepare for our naval future has unearthed objects from our naval past which are part of Portsmouth’s proud maritime history. More than £100 million has been invested in Portsmouth’s naval base to ensure that it is ready for the state of the art Queen Elizabeth class aircraft carriers.

The wealth of artifacts uncovered, include eight cannons, an aircraft engine, 36 anchors and a human skull which was passed to the local police.

There was an arsenal of old ordnance too, ranging from bullets and cannonballs to a British torpedo. A German sea mine and five large bombs were found, before being made safe by the Royal Navy’s Explosive Ordnance Disposal team.

Elsewhere the dredging uncovered bottles, plates, ceramics and shoes which probably belonged to sailors. They have been passed to the project’s archaeologists at Wessex Archaeology for study.

Philip Wise, Principal Project Manager for DIO, said: “We’re delighted with the successful completion of the dredging work. It marks the conclusion of DIO’s £100m infrastructure project to ready Portsmouth for the forthcoming arrival of HMS Queen Elizabeth, of which the dredge was only part. We look forward to welcoming HMS Queen Elizabeth to her new homeport.

Capt Iain Greenlees, Head of Infrastructure at Her Majesty’s Naval Base Portsmouth, said: “The dredging was the culmination of twelve years work monitoring the seabed environment around the harbour and unearthed a huge array of items, some of which may be historically significant, and underlines again Portsmouth’s long maritime history.

Completion of the dredge is the final critical step in a wide range of activities preparing for HMS Queen Elizabeth’s arrival later this year and the base is now ready to support the nation’s future flagship.”

Gerrit Jan van den Bosch, Project Manager for Boskalis Westminster, said: “The Boskalis Westminster team is proud of the challenging dredging project that has been safely completed prior to the arrival of the HMS Queen Elizabeth. With good cooperation and involvement from the Navy, DIO and other parties we look back on a successful project.

Although the main dredging work has now completed there will be an on-going need to remove new material that naturally settles in the channel over time. This will be achieved by maintenance dredging on a yearly basis.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
