Commodities trader Gunvor has sued Torm and Valero, accusing the duo of bringing it damaged cargo, costing it at least $1.65m.

The lawsuit, filed last Friday in Houston federal court, says Gunvor bought 300,000 barrels of naphtha from the Texas oil company and enlisted the 49,757-dwt Torm Thunder (built 2015) to deliver it last autumn.

The cargo was loaded onto the tanker over three days in mid-September, save a 12-hour break on 14 September for line verification.
