Wagenborg Shipping has confirmed that a ballast tank aboard one of its ships has been ruptured.

The 3,250-dwt Priscilla (built 2009) remains in a “stable condition but hard aground” on the Pentland Skerries off Scotland's northern coast with six crew members onboard, UK’s Maritime & Coastguard Agency (MCA) said.

The cause for the 17 July grounding is still under investigation, said Jacko Boorsma, Wagenborg's director of sales and purchase.
