Nordic American Tankers is continuing to fix its older ships, sometimes ahead of rivals’ younger tonnage, chief executive Herbjorn Hansson says.

Asked on a conference call if having some suezmaxes over 20 years of age is causing the US-listed company any trouble, he replied: “The answer is no.”

NAT has added newer ships in secondhand deals of late, but five of its 14m-barrel tankers still date from 2003, 2004 and 2005.
