THE jetty that sank at Shute Harbour, Airlie Beach, earlier this week has been salvaged with "no impact" to the environment.

But it was a slower operation than expected because of rising tides.

Jetty owners Trinity Marine, which trades as Whitsunday Rent A Yacht and Sunsail, issued a statement saying the floating pontoon, which sank on Monday, had been salvaged.

General manager Sedron Hooper said strong winds may have contributed to the subsidence of the pontoon, believed to have partially subsided in the early hours of Tuesday.

A full investigation in conjunction with marine engineers was under way.

"Our salvage team, including commercial divers, was on the scene early Tuesday and had repaired and refloated the pontoon by that afternoon," Mr Hooper said. "Refloating was delayed somewhat due to the rising tide but it was declared fully operational by late Tuesday."

During the operation all containment was overseen by Marine Safety Queensland and Queensland Parks and Wildlife, Mr Hooper added.

The pontoon housed a maintenance shed, which stored equipment and outboard motors.

Mr Hooper said the workshop had been stabilised without incident and there were no impacts on charterers or vessels.

"We'll now look at bringing forward the planned upgrade of the entire Trinity Marine dock facilities to accommodate our expanding fleet and to give our charterers an even better experience in the future," he said.

"...we have temporarily reinstated the workshop to our private jetty and will work with the relevant authorities to determine if any further action is required."
