Tauranga-based stevedoring company C3 Limited has been fined $240,000 by the Auckland District Court for an accident involving a 15 tonne excavator falling from a ship’s crane, narrowly missing five workers on the wharf below.
The incident happened at Northport in Whangarei when the log carrier, Aster K, was being loaded on July 16, 2017.
C3 pleaded guilty to one charge under the Health and Safety at Work Act of exposing people to risk of death or serious injury with the sentence handed down on July 9.
The event happened while one of the ship’s cranes was being used to unload the excavator onto the wharf.
As loading the logs had finished, the excavator’s driver had left the worksite and had not correctly positioned the excavator’s boom so it could be safely lifted by the crane.
When the excavator was lifted the load was unbalanced. An exclusion zone had been set up when the vessel was being loaded with logs but was no longer in place when the excavator was being unloaded.
A C3 employee supervising the lift by the ship’s crane could not see the part of the wharf where the excavator would be unloaded. Later, during Maritime NZ’s investigation, he said he did not feel qualified or trained for the work he was doing.
Another C3 employee was on the wharf where the excavator would be unloaded. He was a trainee who had taken off his radio and neither of the two men could communicate with each other.
Meanwhile, four workers from a company providing biosecurity treatment for the logs and a welder doing repairs on the side of the ship were in the drop zone where the excavator would fall if the lift failed.
None of the five were warned that the excavator was about to be lifted and there were no controls to ensure that they, or anyone else, was clear of the drop zone.
The four biosecurity workers were in a fork hoist when one of them saw the excavator being lifted and moved by the crane. He immediately told the driver to reverse. At the same time, by chance, the welder left the side of the ship to fetch tools from his vehicle.
Seconds later the excavator fell off the crane and crashed down where the five workers had been.
Maritime NZ Northern regional compliance manager Neil Rowarth says it was “sheer good luck that no one was seriously injured or killed”.
“This was seconds away from five workers almost certainly being killed … The five workers had been in the drop zone moments before the excavator fell from the crane.
“The incident happened because C3 did not adequately train some of its stevedores for working around cranes. They did not clear the drop zone below the crane and allowed the excavator to be loaded incorrectly onto the crane.
“Cranes can be dangerous and people working with them must be properly trained,” Rowarth says.
“This is a striking example of employers’ responsibilities to provide good workplace training and safe work practices.
“It should never be just ‘good luck’ that workers come home alive and unhurt,” he says.
