Two P&O Ferries vessels are being inspected as the company attempts to resume normal operations after replacing nearly 800 seafarers with cheaper labour.
The Maritime and Coastguard Agency (MCA) said Port State Control (PSC) inspections are underway on European Highlander, which normally operates between Larne in Northern Ireland and Cairnryan in Scotland, and Norbay, which serves the Liverpool-Dublin route.
