Overhauling of seismic cable spoolers
10. February 2025
Each spooler can accommodate up to eight kilometres of seismic cables. Now, the devices at the base in Farsund are undergoing a major upgrade.

"We are in the process of overhauling the diesel engines that power the spoolers. All the cylinder pistons will be replaced. Additionally, we are working on the hydraulics, including replacing hoses and valves," says workshop manager Ronny Christoffersen.
Outside the workshop, the diesel engines are lined up, awaiting a mechanical overhaul.
"WE ARE CARRYING out a full service on five large spoolers and three slightly smaller ones. Once the job is complete, they will be covered with new tarpaulins," says Christoffersen.
The spoolers, which are stationed on land, are used to spool out and retrieve cables from the seismic vessels operating from the base in Farsund.
WHEN A SEISMIC VESSEL operates offshore, it tows several kilometres of cables. These cables are equipped with geophones and hydrophones, which capture seismic signals.
From time to time, the cables require maintenance. For this task, the land-based spoolers are essential.
