Abstract: A manually-operated canopy deployment system for mounted attachment onboard recreational boats comprises a pair of spring-loaded tubular actuators telescopically assembled and coupled in parallel alignment to deploy a flexible canvas from a roller member transversely mounted between the actuators with a gear box operatively connected to the roller member to control the canvas deployment. Each actuator assembly includes a rearward outer tube, and separate forward and intermediate interior tubes each fitted with inner end caps and coaxially disposed to move longitudinally within the outer tube, with compression springs separately disposed within the respective tube chambers to apply outbound forces axially upon the inner ends of the respective interior tubes. Forward and intermediate cross bars connected across the interior tubes serve to draw the canvas from the roller member and support canvas deployment, with a pair of loop attachments provided on the surface of the canvas to prevent billowing thereof.

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.
