A Singaporean charterer has seized a bulker in Houston over allegations its owner's lack of upkeep forced it to miss out on cheap bunker prices ahead of the IMO 2020 fuel switch.

Dava filed a suit in the US federal court of the Eastern District of Texas on Tuesday, arguing registered owner Domes Shipholding Corp failed to maintain the 33,422-dwt bulker Nodus (built 2010) ahead of a 21 December voyage from a Russian Black Sea port to Brazil.
