  • Patent number: 10518850
    Abstract: Systems and methods are disclosed to provide a fairing block that couples a sonar transducer to a hull of a mobile structure. The fairing block includes a leading edge that diverts water and bubbles in the water laterally around the fairing block and the sonar transducer. A bottom of the leading edge provides a substantially undisturbed water flow over a working face of the sonar transducer while the mobile structure is in motion. The bottom of the leading edge may include a curvilinearly chamfered surface that helps prevent cavitation along the working face of the transducer. One or more lateral cutouts are disposed behind the leading edge to expose lateral sides of the sonar transducer to the water. The lateral sides of the sonar transducer may be metallic and exposed to water by the lateral cutouts, thereby dissipating heat generated within the sonar transducer to the water.

  • Patent number: 10286983
    Abstract: The invention is a chevron ribbon fairing that reduces hydrodynamic drag on marine cables towed by a vessel. The fairing is the shape of a “V,” with an angle between the legs of the “V” chosen on the basis of the predicted cable angle relative to the flow. The chevron angle is twice the cable angle. The tip of chevron ribbon fairing is woven into the outer armor strands of the steel cable or molded to a jacketed cable. When the cable is at shallow angles to the fluid flow, the fairing aligns with the flow, a presents a reduced cross sectional area to the fluid flow behind the towed cable. The chevron design allows the ribbon to naturally align with the fluid flow even as the ribbon rotates about its axis. This ensures a reduction in tangential drag regardless of the level of cable tension.

  • Patent number: 10252780
    Abstract: A cable fairing (fairing) (40) for reducing the flow resistance for a cable (45) has a wing formed cross section with a wide, rounded front and a tapered tail, a through-going cable channel (46) for the cable (45) perpendicular to the cross section of the widest part of the cross section. The wing profile comprises an elastic material of sufficient stiffness to maintain the shape when it is towed thereby causing flow resistance. The cable fairing (40) has slots (42) cut into the elastic material from the tail towards the cable channel (46), so that the tail comprises slats (41) which can be bent parallel to the cable channel (46) to reduce the cross-section of the cable fairing. By this is low flow resistance, as from a stiff cable jacket, combined with sufficient elastic deformability so the cable (45) with attached cable fairings (40), can be winched and pass through narrow openings in the deployment and retrieval, and wound onto a reel for storage and transport.

  • Patent number: 8943991
    Abstract: In one embodiment of the invention, a rope tender is rotatably affixed to the center pull on the tower to carry the rope over wakeboard racks. The rope tender is clamped to the center pull on the tower by a clamp. The rope is then pulled through an end loop on the rope tender and attached to the center pull on the tower. In one embodiment, the rope tender is looped one or more times in the middle to achieve a flexible, spring effect for the rope tender. The rope may also be pulled through the middle loop for support.

  • Patent number: 8783198
    Abstract: A spar hull for a floating vessel can include a hard tank having a belly portion, a fixed strake coupled to the outer surface of the tank and a folding strake coupled to the belly portion of the tank, the folding strake having one or more strake panels and one or more support frames. A method for installing folding belly strakes on a spar hull may include providing a floating spar hull having a hard tank with a belly side, rotating the spar so that the belly side is in a first workable position, coupling at least one folding strake to the belly side of the spar, and coupling the strake in a folded position for transport. The method may include positioning the spar hull offshore in a transport position, upending the spar hull, unfolding the strake, fixing the strake in the unfolded position and installing the spar hull.

  • Patent number: 8727667
    Abstract: A system including a votex-induced vibration (VIV) suppression device dimensioned to suppress a vortex induced vibration of a support structure, the VIV suppression device having a base portion that encircles at least a portion of the support structure and a support member formed along the base portion. The system further including a collar having a body portion defining an annular channel and a flange portion extending outwardly from the annular channel, the flange portion dimensioned to form a receiving channel around the support structure for receiving the support member. The support member is received within the receiving channel to secure the VIV suppression device to the support structure and the VIV suppression device is capable of rotating around the support structure along the receiving channel.

  • Patent number: 8408154
    Abstract: An improved strake for structures that are subject to vortex induced vibrations and motions due to fluid flow around the structure. One embodiment includes a streamliner on the edge of the strake. The streamliner may be added to existing strakes or may be formed at the same time as the strake for extruded strakes. The streamliner reduces vortex induced vibrations and motions of the structure to which the strake is attached. Another embodiment of the invention provides a tension resisting support attached to the strake and structure. The support provides a different load path along the strake than the previously known art for carrying the pressure loading from fluid pressure acting normal to the surface of the strake.

  • Patent number: RE48123
    Abstract: A fairing for the reduction of vortex-induced vibration and the minimization of drag about a substantially cylindrical element immersed in a fluid medium. The fairing also eliminates the galloping phenomenon typically associated with a teardrop-shaped fairing. The fairing having a U-shaped cylindrical shell with opposing edges defining a longitudinal gap and parallel fins extending outwardly from the opposing edges of the shell, the parallel fins being positioned so as to reduce vortex-induced vibration, minimize drag and to eliminate the galloping phenomenon on the cylindrical element.
