Norway’s Gram Car Carriers has secured a further $135.1m in revenue by extending charters for two of its ships.

The Oslo-listed owner said it has stretched a deal for the 6,700-ceu panamax Viking Adventure (built 2016) at a whopping $60,000 per day for five years, well ahead of analyst assumptions and up from $45,000 in May.

The charterer was not named.
