Mr Gaddum said the pending arrival of long or infra-gravity waves has necessitated a suspension to loading on to the ship Corio Bay.
“These waves cause problems in harbours around the world. They cannot be seen as they are usually masked by the sea and swell waves. But they can energise a moored ship and cause excessive movement and surging against the mooring lines.
“As Corio Bay was due to be heavily loaded when the infra-gravity waves were forecast for tonight, we have decided to pause loading so she can be easily moved into safe anchorage in Poverty Bay if needed. Work will resume once the weather event has passed.”
