MOL: Inadequate ballast caused vessel accident

MOL: Inadequate ballast caused vessel accident    Mitsui O.S.K. Line reiterated more definitively Thursday that ballast problems likely caused the roll-on/roll-off vessel 'Cougar Ace' to roll over this week in international waters south of Alaska.
   MOL said it is continuing to interview crew members about the incident, but believes the car carrier suddenly listed because too much seawater was discharged from the ballast tanks at the bottom of the vessel. A swell of the sea caught the vessel at an unstable moment and rolled it, MOL said in a statement.
