Stable Marine Source Control

A novel segmented-foil diverter (SFD) design with the added functionality of being able to remotely control the magnitude of lift that is generated by the diverter is introduced. This capability offers numerous advantages for application to seismic source arrays to stabilize geometry and control positioning. Additionally, the flexible segmented-foil concept provides improved logistics for vessels of opportunity, allows for closer passes around obstructions, and improves operational efficiency while simultaneously reducing back deck HSE risk. A selection of results is presented from a recent sea trial in which one of the source subarrays was fitted with an SFD, complete with a remotely controlled actuator to control the amount of lift being generated. Once the active feedback control capability was engaged, results successfully demonstrated the improvement that was achieved to separation stability during unsteady towing conditions
