    摘要： A flow booster (8) is disclosed, 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 a trawl door (37) comprising an overlapping sequence of several very slender hydrofoils (2), in such a way that the flow booster (8) forms a structurally connected integrated part to the hydrofoil (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 trawl door (39) comprising such a flow booster (8) and some uses of such a trawl door is disclosed.

    摘要： A trawl door (2) for remote-controlled adjustment under water of the active surface area of the trawl door (2). The trawl door (2) comprises an upper and lower surface portion dis- posed on either side of a central axis (6). Each surface portion is provided with an opening (10a, 10b) with an associated, movable damper (12a, 12b) structured in a manner allowing it to be moved, completely or partially, over the opening (10a, 10b). The distinctive characteristic of the trawl door (2) is that said surface portions have a hydrodynamic shape and are comprised of an upper and lower wing (A,B) disposed on either side of a tube (4) formed about the central axis (6); - wherein each damper (12a, 12b) is structured movable along an axis (24) extending transversely to the central axis (6); - wherein each damper (12a, 12b) is movably connected to a driving device.(28a, 28b); and - wherein the central tube (4) comprises a remote-controlled communication and control means (32) for individual operation of each driving device (28a, 28b).

    摘要： The invention comprises a method for depth adjustment of trawl and trawl doors (202) primarily for trawl fishing, where the trawl doors together with a trawl are towed after at least one vessel, where the trawl doors generate an outwards pull on the trawl relative to the direction of movement of the vessel, whereby the trawl remains open, where the trawl doors contain a first set of connecting means (16) for fastening at least one towing wire which is connected with the vessel, where the trawl doors contain a second set of connecting means (220) for fastening at least one wire drawing the trawl. It is the object of the invention to enable depth adjustment of trawl by adjusting trawl doors at the side facing the ship. This object can be fulfilled if the second set of connecting means of the trawl doors interacts with a fitting (222), where the fitting has at least a first and a second position, where the fitting is moved from the first to the second position at the inner side of the trawl doors. In that the trawl doors may be adjusted at the inner side it may be achieved that the trawl doors can be hoisted up e.g. at the stem of a ship with the inner side facing the ship. Adjusting the depth of the trawl may thereby be effected by a relatively simple movement of a fitting. During use of the trawl door, the fitting is of course to be fastened, but a solution with one or more bolts (228,244) will enable adjustment between several positions. Thus it becomes possible to perform a very rapid resetting of the depth of the trawl which thereby may be adapted more easily to e.g. shoals of fishes at different depths.

    摘要： Deflector for towing after a vessel, especially for use in relation to seismic surveys, being adapted to pull equipment to a transversal position in relation to the moving direction of the vessel, comprising at least one connection point (4) for connecting, through wires (12) or similar, to the vessel (7) and the equipment (8) to be towed. Two or more deflector wings (3, 3a) are adapted to provide the deflector (1) with a lifting force transversally in relation to the moving direction of the vessel, at least one of the wings (3, 3a) being provided with a rotating cylinder positioned in front of the wing adapted to increase the lift of the deflector wing, and a drive unit for driving the rotating cylinder with corresponding devices for power supply.
