  • Publication number: 20200251269
    Abstract: Tank for electrical transformer comprising a bottom plate, two side panels and two end panels joined to contain an insulating fluid, and reinforcements joined to the exterior of said panels, wherein the two side panels and the two end panels are vertically curving convex panels, wherein the reinforcements comprise a plurality of arched vertical reinforcements distributed horizontally along each panel. The reinforcements may comprise a plurality of bracing horizontal reinforcements joined between said vertical reinforcements. The inner arching profile of the vertical reinforcements preferably matches the outer curving convex profile of the panels. The horizontal reinforcements are preferably planar. The horizontal reinforcements are preferably located at a horizontal plane in the vertical middle of the respective panel. The horizontal reinforcements are preferably located at a middle horizontal plane or at parallel horizontal planes distributed vertically.

  • Publication number: 20190234161
    Abstract: A drill rod for breaking up the edge of a hole comprises a cylindrical body, a buffer and injector nozzles. The drill rod injects air and water through its injector nozzles at the material deposited at the edge of the hole, thus achieving the breaking up thereof without the need to use auxiliary equipment or manual operations. A method for breaking up the edge of a hole is described, including using a rod to break up the edge of a hole, and comprising the stages necessary to perform this operation using a drill.

  • Patent number: 10196111
    Abstract: The present invention is related to a gravitation anchor for offshore anchoring of ships and platforms, comprising a main body (10) with a longitudinal axis of revolution (11), comprising a means of stabilization (14), whereby the means of stabilization (14) comprises a means of automatic activation (140). Optionally, the means of stabilization comprises at least one stabilizer (14), whereby each stabilizer (14) comprises an end pivotally attached (141) to the gravitation anchor (1), and a free end, whereby when the stabilizer (14) is in a retracted position, the free end is positioned closer to the main body (10) of the gravitation anchor (1), and whereby when the stabilizer (14) is in an extended position, the free end is positioned away from the main body (10) of the gravitation anchor (1).

  • Patent number: 6655308
    Abstract: The present invention relates to a passive stabilizer (3) which is installed in the lower part of a tanker used in floating production systems which make use of a mechanism which enables the tanker (1) to rotate about a vertical axis (turret). The stabilizer gives the tanker greater directional stability and makes it possible to install the turret in a more central position along the tanker.

  • Patent number: 6176191
    Abstract: This is a mechanical element intended to control the rolling of FPSO type petroleum production systems which use adapted decommissioned ships as the floating facility. The bilge keel is made up of two lines of plates, continuous or sectioned, in this case with a small separation between each two adjacent sections, mounted along the bilge of the ship, one on either side, at right angles to the hull, and characterized basically by being wider and having a greater total length than the conventional bilge keels used in ships.
