IM Skaugen has recorded a victory in its ongoing dispute with Volkswagen-owned MAN Diesel & Turbo as the latter has been compelled to pay a refund of $15.5m.

The Norwegian owner said an arbitration tribunal found that two engines produced in 2008 and 2009 had “a substantially higher consumption than the maximum level warranted by MAN”.

The ICC International Court of arbitration has ordered MAN to refund IM Skaugen its down-payment for the engines of EUR 5.3m
