Belgium's Euronav reported a net loss of US$ 31-million in its Q4 2012 financial report. The result of the fourth quarter is affected positively by the revaluation at marked-to-market levels of non cash items (unrealized) such as hedge instruments on interest rates for a total of US$ 600,000. After successfully implementing a strict slow and super slow steaming policy whenever possible, Euronav continues to apply measures to reduce fuel consumption across its spot fleet. The company has already retrofitted a VLCC, with a Mewis Duct, improving propeller efficiency, which demonstrated to be the most efficient energy saving device. The same retrofitting will be done on at least 4 Suezmax vessels this year.
