摘要： A commercial fishing trawl has a net and a mouth opening defined by a head line, a foot line, and side lines. The mouth opening is spread by a plurality of foil segments threaded on one or more of the head line, foot line, or side lines. Foil segments may also be threaded on tag lines or foil lines attached about the mouth opening to spread and maintain the mouth opening as the trawl is towed through the water, behind a tow vessel.

摘要： A ribbon-foil depressor is incorporated into a towed seismic array to provide downward lift to array sections or components. The ribbon-foil depressors may be deployed on the port and starboard spur lines or on the outboard separation ropes. The ribbon-foil depressors may be used to submerge and operate seismic equipment at depths as low as 60m or more and are capable of maintaining towed seismic streamer cables at these depths and still remain stable through various speed changes and turns.

摘要： A foil for a towed cable includes a body defining at least two conduits. The body has a foil shape having a leading edge and a trailing edge. The foil shape defines a first surface extending between the leading edge and the trailing edge configured to provide lift. The foil shape defines a second surface opposed to the first surface extending between the leading edge and the trailing edge. The foil shape defines first and second lateral sides that extend between respective lateral edges of the first and second surfaces, the leading edge, and the trailing edge. A first conduit is defined within the forward half of the body adjacent to the leading edge, is open to each of the first and second lateral sides, and is configured to receive a cable therethrough. A second conduit may be defined within the body and filled with buoyant material.

摘要： A foil having a leading edge, trailing edge, chord and span is attached between a first head float position and bottom submerged position below the head float on the array. The foil being flexible along its span and has a first interior conduit rearward of the leading edge and a second interior conduit forward of the trailing edge. The conduits are centered on the chord and separated by a distance. A first cable having a first length is strung inside the first conduit and a second cable having a second length is strung inside the second conduit, and an adjustment mechanism is used to vary the length of the first cable relative to the length of the second cable and vice versa.
