  • 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.
