Greek tanker company Tsakos Energy Navigation (TEN) is preparing to sell some of its oldest 60-plus tankers as it awaits delivery of four LNG dual-fuel aframax newbuildings.

The Nikolas Tsakos-led company revealed on Thursday it is even “exploring additional opportunities for similar technology” newbuildings with a view to achieving a fully “green” fleet by 2030.

TEN aims to have “the vast majority, if not all” its vessels on modern propulsion fuels, whether LNG or alternatives, Tsakos told analysts in a conference call after releasing fourth-quarter earnings.
