US-listed Tsakos Energy Navigation (TEN) has clinched a period charter deal with Stena Bulk of Sweden for its 157,000-dwt tanker Eurovision (built 2013).

The agreement is for 18 months at $25,000 per day. Tsakos bought the tanker as a resale from a Korean owner in 2012 for $52m.

The deal lifts the number of suezmaxes in the Stena Sonangol fleet to 24 units.
