In the early hours of 8 October, a chemical tanker YM Uranus collided with a bulk tanker some 100km southwest of the island of Ouessant, off the Brittany coast. At the time of the incident, in addition to an unreported amount of bunker fuel, the Uranus was carrying a cargo of 6000 tonnes of pygas solvent, a type of heavy gasoline. Although a lighter type of oil (and therefore less persistent once spilled), this type of product can still pose a risk to seabirds through interfering with feather waterproofing and causing skin burns or irritation.
