Hopes high on Cornwall wave energy attempt

The Wave Hub is due to undergo tests in the autumn

Engineers struggling to bring a cable ashore for a wave energy scheme in Cornwall say they are "100% sure" they have fixed the problems.

The team behind the £42m project hope to begin bringing the cable ashore on Thursday.

The cable for the Wave Hub project is being floated to shore from a ship 2km (1.25 miles) offshore near Hayle.

A flotation jacket around the cable failed last week, causing it to sink.

Project manager Jim Cole said: "I am 100% sure we'll get it ashore at the moment.

"Everything has an element of luck and I'm afraid this one didn't run with us very well.

"Our main concern is to get the cable ashore safely."

Once the cable end is floated to about 200m (650ft) off Hayle Towans Beach in St Ives Bay, it will be winched up the beach and joined to a nearby electricity substation.

Afterwards, the ship Nordica will lower the 12-tonne Wave Hub on to the sea bed.

The hub, which will send energy from machines on the sea surface to wave power units ashore which link to the National Grid, is due to undergo a series of tests in the autumn.
