Mitsui OSK Lines has rejected media claims that contaminated fuel may have played a part in causing a high profile casualty that saw a bulker run aground and break up off Mauritius.

The Japanese shipping giant, which was charterer of the 203,000-dwt bulk carrier Wakashio (built 2007), rejected suggestions reported in Forbes that the vessel may have suffered mechanical issues prior to the grounding because of its use of low-sulphur fuel.
