Tsakos Energy Navigation, a US-listed owner of more than 80 tankers on the water or under construction, is eying sales of ageing assets after placing a giant $1.34bn newbuilding order earlier this month.

In its annual results released on Thursday, the Nikolas Tsakos-led company confirmed a TradeWinds report from 19 March that it sold the 158,500-dwt Pentathlon (built 2009) and said that more such deals are in the pipeline.
