The expanding VLCC company said Svein Moxnes Harfjeld will be joined by Trygve Munthe, who was previously president.
The pair have been in the top positions at DHT since 2010.
Chairman Erik Lind said: "Svein and Trygve have since they joined the company in 2010 for all practical purposes functioned as a management team of equals.
“Their formal appointment today as co-CEO's with shared responsibility to run and develop the business of the company is thus a reflection of how effective they have been in managing the company in this manner and it will not impact other areas of DHT's management structure."
