A crane has capsized on a barge in Milford Sound this afternoon and officials are bracing for an oil spill.
Around 200 litres of diesel and 24 litres of oil are in the crane, which tipped over when piling. It now sits on its side with the boom resting on a pile.
There is an additional 1600 litres of oil in a hydraulic power pack which is also sitting on the barge.
Environment Southland has initiated a response which included booming and skimming the oil off the surface in Freshwater Basin.
On scene commander Dallas Bradley says they have to wait for a health and safety inspection before the fuel can be removed.
He says the situation is considered stable.
