The chief financial officer of Oslo-listed Magseis Fairfield has quit.

The survey ship company said it had been notified by Tom Henrik Sundby of his decision to resign.

He has been replaced by Kevin Crosby on an interim basis.

Crosby was previously CFO at Fairfield Geo Technologies.

“We are grateful for Tom Henrik’s contribution to Magseis Fairfield’s growth and development into an ocean-bottom seismic technology leader," Magseis Fairfield said.
