Russian state shipping company Sovcomflot (SCF Group) has secured a 50% discount after extending a seismic survey ship charter for three years.

Middle East owner Polarcus said its counterparty has exercised firm options to keep the 2,250-dwt Vyacheslav Tikhonov (built 2011) on a bareboat charter basis until 2023.

In June, Sovcomflot had said it was revoking its notice of redelivery to retain the ship until the third quarter.
