Norway's Siem Offshore has sold an elderly platform supply vessel (PSV) formerly trading in Brazil.

It said it had concluded the disposal of the 4,300-dwt Siem Supplier (built 1999) to an unnamed buyer.

AIS data shows the vessel has journeyed from Rio to anchorage in Malta.

Siem Offshore said on Thursday it was starting talks with bondholders over a financial restructuring.
