Responds to increased ECA demand with launch of LSFO supply barge. OW Bunker, a global supplier and trader of marine fuel and lubricants, has announced that it will supply low sulphur 1% RMG 380cst fuel from Balboa, Panama from mid-October 2012. The move will serve to meet the growing demand from customers transiting the North American ECA zones. The company's local supply tanker, MT Star Alpha, has been released from dry-dock following modifications to the supply vessel's tanks to provide complete segregation of LSFO products, which is vital to ensuring quality.
