Oslo-listed Siem will pick up $282m from the exit of the duo, in what is a rare second hand transaction in the sector.

Daya, which already has the Siem Daya 1 and Siem Daya 2 (both built 2013) on long-term charter, now has 150 days to get the cash together to complete the purchase.

If it fails to do so, the charter contracts will remain in place.
