Mjolner Shipping has netted a profitable rate by reletting an aframax tanker that it chartered from John Fredriksen’s Seatankers Management.

Last month, the US tanker operator took the 109,000-dwt Sea Bay and Sea Hope (both built 2009) on charter for for two years at $28,000 per day, brokers said.

Mjolner is now understood to have chartered the Sea Bay out to commodity trading giant Mercuria for a year at $42,500 per day.
