Tsakos Energy Navigation (TEN) is entering three vessels in the Cargill-Maersk Tankers joint MR pool.

The three MRs — the 53,000-dwt Apollon, Aris and Artemis (all built 2005) — will join the pool this month from Singapore, Gibraltar and the US Gulf.

They are part of the US-listed TEN fleet, which includes three further sisterships, the Ariadne, Afrodite and Ajax (all built 2005).
