OW Bunker announced that it has entered into agreements with the Rubis Tank Terminal in Rotterdam and the Vesta Tank Terminal in Antwerp, to allow for increased access and guaranteed supply at key bunkering ports. The investment in direct supply facilities comes in response to increasing demand for RMK 1 percent 500 cst fuel oil, a cost-efficient low sulphur fuel, which offers savings for operators transiting within the European ECA. OW Bunker Netherlands' exclusive contract with the 72,000-cubic-meter Rubis Tank Terminal in Rotterdam will support the supply of all grades of marine fuel on both spot and contract basis, and will guarantee supply of RMK 1 percent 500 cst fuel oil.
