Trader Koch continues to be busy taking tanker tonnage on period charters, with ships from Tsakos Energy Navigation and Alma Maritime the latest to be picked up.

Koch has chartered the 299,000-dwt tanker Hercules 1 (built 2017) for 12 to 18 months, sources say.

New York-listed TEN announced earlier this month that the ship had been fixed by a major charterer but did not reveal any details.
