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 trawl door (37) comprising a flow booster (8) and an overlapping sequence of several very slender hydrofoils (2) is disclosed, the flow booster (8) being shaped as a thick hydrofoil with an internal cavity (32), being aerodynamically inefficient on its own with a bulky relative thickness larger than 24 % and being arranged to be positioned substantially below the rear part of the trawl door (37), in such a way that the flow booster (8) forms a structurally connected integrated part to the hydrofoils (2) and impacts the upstream flow forcing it into a velocity boosted region (28) upstream of the flow booster (8) and to the pressure side (31) of the conventional part of the trawl door (1), such that the flow is pre-accelerated prior to running through the conventional trawl door channels (29) between the hydrofoils (2). Furthermore, a flow booster (8) for such a trawl door (37) and some uses of such a trawl door (37) are disclosed.

摘要： A variable rigidity tow cable for attaching a first vehicle with a second vehicle. The tow cable includes a tension control cable having a first end and a second end. Tension on at least one of the ends of the tension control cable can be controlled to increase or decrease the length of the tension control cable. A plurality of beads are slidingly disposed on the tension control cable between the first end and the second end. The beads are free to move relative to one another on the tension control cable when the tension control cable is slack, and the beads are engaged with each other to form a rigid structure around the tension control cable when tension is applied to the tension control cable.
