Tsakos Energy Navigation (TEN) has secured time charter contracts for four of its tankers, the company has confirmed.

The US-listed shipowner said the vessels involved include an aframax, two panamaxes, and a handysize product tanker.

However, the Greek shipowner was less than forthcoming with rate and counterparty details other than to say they are “major end users”.

TEN added that the average contract length of all four fixtures is 14 months which bring the aggregate fleet gross revenues to a minimum of $1.4bn.
