OCEAN FLOOR DREDGING
TENSION LEG PLATFORM AND METHOD FOR INSTALLATION OF THE SAME
Miloslav Malecha, Zoetmeer, Netherlands assigned to Manaco International A system of ocean floor dredging comprises a first vessel, two rotatable rollers on the vessel, a third roller lying on the ocean floor, and an endless net extending around the three rollers.
4938164 SELF-PROPELLED M A N N E D SUBMERSIBLE VEHICLES FOR UNDER-SEA EXCURSIONS Jean-Michel Onofri, 13880 Velaux, France A self-propelled manned submersible vehicle of the type comprising a pressure-resistant capsule (1) serving as a cabin, ballast tanks (3, 8), releasable ballast (7), propulsion units (4) having propellers driven by electric motors, and storage batteries (42), the pressure-resistant capsule (1) comprises a peripheral window constituted by a vertical cylindrical sleeve (19) which is entirely transparent, the sleeve is of sufficient diameter to house a plurality of people sitting side-by-side, and extends upwardly from a hemispherical bottom (14) and downwardly from a spherical cap (16) which is extended by a cylindrical conning tower (21) which is closed by a hatch (22).
Rolf Eie, Osters s, Norway assigned to Norwegian Contractors A/S A tension leg platform for drilling and/or production, processing and transporting hydrycarbons from sub sea wells or installations, and methods for installation of such platform. The platform comprises in operational position the following: a working platform which has position above the sea level, a buoyant body (1) which is connected with the underside of the platform and has substantially position below the surface, and a number of tension legs (13) which connect the buoyant body (I) with a fundament anchored to the sea bed. The invention is characterized in that the lower parts of the tension legs (13) in per se known fashion are anchored to the fundament (14) and at their upper ends are controlled in guides (20, 21) on the outside of the buoyant body and are attached to the buoyant body (1) above or just below the water line.
