OW Bunker, founded in 1980, was a marine fuel (bunker) company based at Nørresundby in northern Denmark. It was the world's largest bunker supplier until its collapse on 7 November 2014. It went from initial public offering (IPO) to bankruptcy in less than a year. The dramatic collapse of the company led to expedited litigation in the English courts (as all the contracts had been declared to be "subject to English Law").
