The Master of the Mellum Trader requested AMSA’s assistance on Tuesday afternoon, reporting the vessel had a list (a tilt) of around 35 degrees.
AMSA tasked a surveillance aircraft from Broome to locate the vessel 190nm north-west of Broome and diverted two tugs to attend the area.
The Mellum Trader altered its course away from the coast to position itself with the ocean’s movements to allow for the vessel to decrease its tilt down to 15 degrees.
The crew also conducted some ballasting of the vessel, which contributed to the improved position.
Early this morning, the vessel’s master reported the situation had stabilised and no further risk had developed overnight.
The Mellum Trader is continuing on this course away from Broome, with tug Far Scimitar in company to provide assistance if required.
It is unknown at this stage what may have caused the vessel to tilt.
The Mellum Trader has 13 people on board and is carrying oil well development casings. The weather conditions include strong winds and rough seas.
Another update will be issued when more information is available.
