Oslo-listed Rieber will shoulder a fourth quarter charge of $13.51m on the deal.
Irene Waage Basili, chief executive of Rieber, says the sale fits a plan to focus on three core areas.
“We see exciting opportunities in ice/support, subsea and also within seismic,” Basilim said.
“We have to exploit our strong financial position, by selectively pursue growth opportunities we believe will provide the best return.”
