  • Gravitation anchor for offshore anchoring of ships and platforms
    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).

  • Passive stabilizer for floating petroleum-production systems
    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.

  • Bilge keel and method for FPSO petroleum production systems
    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.
