A $600m drillship is up for sale again following a move to a port in Wales.

The 61,600-gt Sertao (built 2012) has been moved from Tilbury as Platform Brokers (PB) seeks a buyer.

Seller Dleif Drilling, a US-registered company, took possession of the vessel after a court order in Brazil.

It used to be owned by Brazil’s bankrupt Shahin Group and was on long-term charter to Petrobras.
