The ship carried a crew of 27 - 3 Greek, and the remainder Phillipine citizens. 3 have been found dead, six survivors have been recovered, and 18 are still missing. The six survivors are in hospital, and are said to be in critical condition.
The 171-metre (570-foot) MT BOW MARINER was owned by Norwegian shipping-company Odfjell ASA, was registered in Singapore, and classed by det Norske Veritas.
The cargo - industrial ethanol, which is used in the manufacture of varnishes and perfumes, and as an additive in fuels and petrol - is not expected to constitute an environmental problem. If the ethanol leaks out, it will evaporate rapidly - but the vessel was also carrying 700 tons of fuel oil, which will be a problem when it leaks out.
