'Not surprising' for eco vessels to command premium 2nd September 2013 05:30 GMT Eco MR tankers commanding premium of $8,000 per day on trans-atlantic route Eco-type vessels that consume less bunkers allow owners to save on cosst without a sacrifice in operational integrity, says a Poten & Partners (P&P) report. The shipbroker says that a medium range (MR), 'eco' tanker is able to save 14.5 metric tonnes (mt) of fuel per day when travelling at 13.5 knots on a laden leg, compared to a standard MR vessel. This, and the lower consumption of fuel at other speeds, has resulted in an average earnings premium of $8,000 per day favouring the 'eco' MR tanker in the trans-Atlantic market.
