We are halfway through our project with DiveCo Marine Ltd to improve the moorings at Keyhaven River.  This short drone video shows the work underway, as well as how beautiful the coastline is at Keyhaven.

We have appointed DiveCo Marine Ltd to upgrade and improve the 4,000 metres of boat moorings in the Keyhaven River, Keyhaven near Milford on Sea.

David Hurd, our Keyhaven River Manager who manage the moorings in the river, explains the project, "A boat mooring system, put simply, is like a parking space for boats. It needs to be secure and strong enough to keep boats safe in the worst of weathers."

The current ground chain system is 19 millimetres thick and we are replacing it with much heavier more durable chain. David said, "The chain we'll use will be 28 to 38mm thick and is made of heavy iron. This thicker and heavier ground chain will sink deeper into the mud, making it more secure and extending the working life of it, reducing maintenance costs."

The first stage of works will remove and then replace 200 metres of chain at a time. All chain recovered will be checked and any suitable chain will be re-used in the river, the rest will be sold for scrap.

60% of the chain being used is reclaimed, some of it heavy mooring chain previously used by Trinity House to secure navigation marks to the seabed around the coast of the British Isles.

The work, which started at 5am yesterday (Wednesday 3 March 2021), will take about eight weeks to complete, conditions allowing, and the heaviest areas of ground chain should last 10 years or more.

Boat owners who have moorings at Keyhaven have been updated regularly to keep them informed of the progress of the project.

Drew Allan, Projects Director for DiveCo Marine will be overseeing the works, "With an office in Lymington, DiveCo are proud to have been awarded the contract to provide a reliable mooring system throughout the Keyhaven River. Our marine engineering and construction experience in some of the most tidal waters in the UK stands us in good stead to complete the works at Keyhaven. We are looking forward to working closely with NFDC to install the new system and enhance the moorings for the river users and mooring holders."

The DiveCo Marine team are using a specialist 'Jumbo spud leg' barge to recover and re-lay the 200m sections of chain and mud anchors. This craft allows the crew to efficiently reach all areas of the river system with minimum disruption.
