20080304915 | Method and Device For Attaching a Subsea Cutting Apparatus - A method of and a device for attaching a cutting apparatus, the cutting apparatus comprising a framework structure and a cutting head which can be displaced relative to the framework structure, and where, during the cutting operation, the cutting apparatus is tied in to the seabed by means of at least one attachment. | 12-11-2008 |
20090269144 | Extraction System For Removable Marine Footing - The present invention describes an extraction system ( | 10-29-2009 |
20100021241 | SUCTION PILE SUITABLE FOR SHALLOW DEPTHS - A suction pile comprising a cylindrical wall and a piston that is movable inside the cylindrical wall. The cylindrical wall has one suction end suitable for sinking into an ocean floor. The piston delimits two chambers, one being able to be filled with water. The suction pile includes a pump for extracting the water from the one chamber and for causing the sinking of the suction end. The pump comprises a device for stopping the piston while the cylindrical wall has one water intake end to allow water to enter into the other chamber. The piston is alternatively stopped and driven in movement as the suction end sinks. | 01-28-2010 |
20100086364 | Subsea Suction Pile Crane System - A subsea suction pile crane system comprises a suction pile and a crane mounted on the suction pile. The crane comprises a rotatable mounting surface, a winch, and a boom having a proximal section attached to the rotatable mounting surface such that the boom can pivot with respect to the mounting surface, and a distal section opposite the proximal section. In embodiments, a plurality of suction piles may be sed. The crane system is typically hydraulically operated. A preferred embodiment of the invention may further comprise a remotely operated vehicle comprising a hydraulic power supply operatively coupled to the crane, and a manipulator arm mounted on the distal section of the boom and operatively coupled to the hydraulic power supply. | 04-08-2010 |

20150314833 | CORROSION-AND-CHAFING-RESISTANT, MOORING SYSTEM AND METHOD - A mooring system provides an anchor, imbedded in a sea floor from which arises a line to a mid-line float resisting entanglement by operation of a “worm grip” providing a tortuous path without exceeding permissible working loads nor reducing the tension capacity of the line. A slack region accommodates changing tides, before entering into an upright tube weighted at a lower end and flanged at an upper end thereof to secure a buoy in place. The embedded anchor is driven into the sea bed by hydraulic water jet drilling. From a thimble in the anchor to a thimble in the upright at the buoy, no intervening metal components are needed in the load path. Markings are durably and protectively embedded in recesses below the buoy's outer surface. | 11-05-2015 |
