Residents have told how loud bangs and shaking ornaments sparked by seismic testing are causing misery for neighbours living near the River Wyre.
One Fleetwood resident says he is constantly being interrupted by ‘explosions’ while gas storage company Halite performs exploratory tests along the Wyre estuary.
The survey is being carried out ahead of controversial plans to store millions of tonnes of gas under the Wyre.
But John Mole, of Voyager Way, Fleetwood, says they are causing a nuisance.
He said: “In the leaflets they sent us they described it as being a few dull thuds, but it sounds like controlled explosions.
“When they get level we can feel things shaking, it’s really unpleasant and sometimes it goes on for a few hours.
“You can feel everything vibrate.”
Mr Mole, who lives with his wife Laura, claims the testing is also going on until 9pm.
Halite does not currently have planning permission to store gas at Preesall as it awaits for the result of a judicial review over the planning inspectorate’s refusal to allow it.
But it is allowed to carry out the tests while the review is pending.
Coun Ron Shewan, who represents Fleetwood East on Lancashire County Council, says he has also been made aware of the problem.
He said: “People are having to put up with these tests and there are some quite substantial bangs.
“I can understand people getting upset and expressing their annoyance.
“I’m going down to County Hall and I’ll be asking some questions.”
As part of the seismic work, security personnel have been drafted in to keep guard on the area all day, every day.
Coun Phil Orme, a Preesall Town Councillor from Knott End, says he has received around half a dozen complaints about the work so far.
He said: If you didn’t know better you’d think there was an artillery range over the hill.
“We live on a platform of clay at this end of the village and with the dry weather you can feel it under your feet, the lady next door thought her roof was coming in.”
“It must be incredibly unpleasant.”
The work is being undertaken by TESLA, on behalf of Halite.
Keith Budinger, chief executive of Halite, said: “TESLA works to very strict industry standards to establish safe distances from properties to minimise any risk of damage and ensure that the work is carried out within agreed tolerances.
“We are surprised that The Weekly News has received a complaint about the timing of the testing.
“TESLA keeps stringent records to monitor daily activity; TESLA’s working hours are dictated by the tide times affecting the Wyre Estuary and no work is being carried out between dusk and daybreak.
“We have received one inquiry from a member of the public in connection with this issue and, following monitoring of the vibrations in the vicinity of her home, have reassured her that the tests are being undertaken within agreed tolerances, which she was happy with.
“We have received no reports of ornaments falling off walls or similar incidents.”
