A GROUNDED coal ship caused havoc on the Gladstone Harbour as it brought Curtis Island ferry services to a standstill.
After losing its mooring lines at Barney Point Coal Terminal, the ULUSOY-12 bulk coal carrier began pivoting in the water at almost 180 degrees.
Three marine pilots and five tugboats were sent out at 5.10am on Wednesday to assist the vessel.
A spokesperson from Gladstone Ports Corporation said no injuries or environmental damage were caused as a result of the incident..
"ULUSOY-12 was almost finished loading at Barney Point Coal Terminal when the vessel's mooring lines parted and the vessel drifted away from the berth and into the shipping channel," the spokesperson said.
"The vessel touched bottom, dropped anchor and did not continue to drift further into the shipping channel.
"GPC understands that no one was injured in the incident and no pollution of surrounding environs occurred."
Early morning commuters on their way to Curtis Island via ferry were impacted only minimally, according to Bechtel general manager Kevin Berg.
"Two of our early morning ferries experienced some delay," he said.
"Passengers were sent from the wharf back to the ferry terminal as a precautionary measure.
"These employees were transported across to Curtis Island about 6.05am when the ferries returned to normal operations."
Maritime Safety Queensland said the incident led to a review of the current mooring procedures.
ULUSOY-12 left the port of Gladstone at 11am, after a thorough engine and steering inspection.
