A Wah Kwong Shipping-owned ultramax bulker ran aground Thursday on the Panara River in Argentina.

The 63,300-dwt Pilatus Venture (built 2016) has been immobilised on South America's second longest river since 1530 local time, according to Argentinian law firm Vega & Co.

The ship is positioned 325 kilometres west of where the river meets the Atlantic Ocean, said Vega & Co partner Alejandro Vega.
