MacArtney Solution for ION’s Seismic Ops

New technology developed by MacArtney and ION Geophysical has been launched to gather data for enhanced exploration and production of oil and gas.

The technology is in the form of a SailWing actuator and control system designed to ensure the correct positioning and stability of seismic survey source arrays.

Earlier this year MacArtney provided six customised SailWing actuators for use in a control system for ION Geophysical.

Traditionally, source arrays are stabilised by a complicated connection of ropes and deflectors. The SailWing actuator is installed in each source head float and controls the SailWing angle of attack, which stabilises the array with software controlled adjustable lift, MacArtney explains.

Control of SailWing happens via ION’s Orca or Gator navigation system interfacing with the electronic control rack that then communicates with the actuator, signalling the mechanism to adjust the lift provided by the SailWing.

MacArtney has designed and manufactured the SailWing actuators, control system topside rack, power supplies and a remote control box allowing for manual control of each SailWing actuator.
