THE Eco Shark Barrier should be fixed and available to the public this week.
The southern portion of the barrier, which is based at Coogee Beach, was damaged during Perth’s recent wild weather.
Inventor Craig Moss said replacing a plastic clip, linking cables and a float, with a stainless steel one had made the structure weaker, rather than stronger.
“If it was a steel clip with steel cable it would have been fine,” he said.
“I’ve been saying the barrier didn’t fail, I failed the barrier.”
Mr Moss remained confident the barrier could stand up under extreme weather conditions, pointing to the 300m section running adjacent to the beach and the northern section, which was undamaged by the storm.
“The steel clip wore through the cable,” he said.
“It’s my mistake. You live and learn.”
Cockburn’s infrastructure services manager Doug Vickery said the City had not lost faith in the technology.
“This has been a good test of the barrier in severe winter conditions, which was the intent of leaving the barrier in the ocean over the several winters of the leasing period,” he said. “As a result of what has been observed, (Mr Moss is) changing the top securing rope and float fastenings of the southern section to make the barrier even more robust.
“The City has full confidence that the barrier will continue to offer swimmers a safe swimming environment for the remainder of the trial period and potentially beyond.”
