Australasia Charterers has been thwarted in its attempt to obtain security for its claims against a Singaporean company controlling a ship stuck offshore China.

US district court Judge Ricardo Martinez ruled that Australasia made a probable claim that Worldwide Bulk Shipping owes it $3.9m and counting as the 92,900-dwt bulker Necklace (built 2012) is prevented from discharging its cargo of Australian coal due to an import ban.
