摘要： The present invention relates to a controllable trawl door (2) comprising a plurality of hydrofoils, one or more positional control means (7) for changing the equilibrium position of the controllable trawl door, front-towing attachment facilities configured for being attached to a towing wire (3), rear-towing attachment facilities configured for being attached to one or more bridle wires (4), and a controller comprising a motion detection system. The controllable trawl door comprises means for detecting changes in towing force applied to the controllable trawl door during operation and for changing the equilibrium position of the trawl door within the water during operation. The present invention further relates to the use of the controllable trawl door and to a simple method for communication between a towing vessel (1) and trawl doors based on traction variations in the wires towing the trawl doors

摘要： A trawl sensor device for monitoring trawl doors and the distance of the trawl to the bottom during trawling operations comprises at least one acoustic transmitter and receiver, the transmitter being adapted to be positioned such that an acoustic signal is transmitted towards the seabed at a forward-pointing angle, and means for communication between the sensor device and a vessel. The transmitted acoustic signal is reflected from the seabed and is received at this position and the distance between the acoustic transmitter and the seabed is calculated based on the difference in time between transmission and reception of the acoustic signal and the forward-pointing angle.

摘要： An improved self-spreading trawl (13) includes first panels (56T, 56B) which when towed through a body of water (12) separate on opposite sides of the trawl's central axis (62). Portions of panels (56T, 56B) form portions of the trawl's mouth (26). The trawl (13) also includes second panels (56P, 56S) which separate on opposite sides of the central axis (62) from the sides occupied by the panels (56T, 56B). Portions of panels (56P, 56S) form portions of the trawl's mouth (26). Regions of panels (56P, 56S) generate more outwardly directed lift than corresponding regions of the panels (56T, 56B). When towed through the body of water (12): a) a distance separating the panels (56P, 56S) exceeds; b) a distance separating the panels (56T, 56B). Also a braided product strand which includes at least 3 plaits (76, 102), at least one (76) of which is larger than the others (102), advantageously exhibits less drag and vibration.

摘要： Mesh cells (30) for machine-made netting (51) use pairs of mesh bars (35) made from a continuous length of material and meet at a common coupler (34). Such mesh bars (35) have a lay with a common direction throughout the length of material. In a zig-zag pattern used in knitting machine-made netting (31), the longitudinal axis of symmetry (38) of mesh bars (35) turns at each coupler (34). Towing such mesh bars (35) causes water to flow past pairs thereof in two different directions with respect to their common lay. The directions of water flow are neither parallel nor perpendicular to the longitudinal axis of symmetry (38) of the mesh bars (35). As water flows past the mesh bars (35), the cross-sectional shapes of the mesh bars (35) produce a net component of force that is oriented in a direction perpendicular to a combined drag component of force for the mesh bars (35).

摘要： Mesh bars (35, 283) of a trawl (13, 263) include at least a portion having a corkscrew-shaped pitch which exhibits a hydrofoil-like effect. Such mesh bars (35, 283) are preferably formed from a material having a substantially incompressible cross-sectional shape. By appropriately selecting the lay and leading edge of mesh bars (35, 283), movement of the trawl (13, 263) through the water entrained environment creates a pressure differential and lift across that portion of mesh bars (25, 283) which exhibit the hydrofoil-like effect. The lift thus created increases performance characteristics of the trawl (13, 263) including increased trawl volume, improved trawl shape, and reduced vibration, noise, and drag. Obtaining the greatest improvement of trawls (13, 263) requires controlling a pitch range for twisted product strands (e.g. twisted ropes) (36, 37), and for straps (284) forming mesh bars (35, 283). For straps (284), control of a width to thickness ratio also significantly affects performance of the trawl (13, 263).
