Hydrodynamic depressor for marine sensor streamer arrays
A hydrodynamic foil system for a sensor streamer array includes at least two tow ropes (8) each coupled at one end to a survey vessel (10) and at the other end to a paravane (14), the paravanes configured to provide lateral outward force as the vessel and paravanes are moved through a body of water....

| Zusammenfassung: | A hydrodynamic foil system for a sensor streamer array includes at least two tow ropes (8) each coupled at one end to a survey vessel (10) and at the other end to a paravane (14), the paravanes configured to provide lateral outward force as the vessel and paravanes are moved through a body of water. A spreader cable (24) is coupled to each of the paravanes. A plurality of laterally spaced apart sensor streamers (20) coupled at forward ends thereof to the spreader cable (24). A plurality of foils (25) is disposed on the spreader cables. The foils (25) configured to provide hydrodynamic lift in a vertical direction as the spreader cables are moved through the water. |
