OCEAN Network Express (ONE) has confirmed that around 60 containers were lost overboard with a further 80 damaged in the recent stack collapse on its containership Madrid Bridge.

The 13,900 TEU ship, on the company's EC4 service from Asia to the US east coast, suffered the stack collapse mid-Atlantic and is currently travelling at 19 knots, according to AIS data on VesselsValue, reports UK's The Loadstar.

The Madrid Bridge has tracked south, and is now north-east of the Caribbean, to circumvent a storm, originally thought to be heading for New York.

ONE confirmed: "Based on initial investigations, it is estimated that approximately 60 units were overboard, and 80 units were damaged. The numbers may be updated after further investigations."

It added: "The vessel is currently proceeding towards the east coast of the United States and, if all goes well, will be calling in Charleston for a detailed assessment of the vessel condition and to discharge the affected containers."
