20100230953 | Coaxial Pipe Element and a Method of Fabrication - The present invention relates to a method of fabricating a coaxial pipe element ( | 09-16-2010 |
20100282353 | Coaxial Pipe Element In Which The Inner Pipe Is Under Strees, And A Method Of Fabrication - The present invention relates to a coaxial pipe element comprising an inner pipe and an outer pipe and having at each of its ends a closure of the annular space between these two pipes, in particular by means of a forging, and in which said inner pipe is subjected to traction stress. | 11-11-2010 |
20110005452 | Buoyancy device and a method for stabilizing and controlling the lowering or raising of a structure between the surface and the bed of the sea - A method of using a buoyancy fluid presenting density that is less than that of sea water, and that is confined in a rigid or flexible leaktight casing, so as to constitute an immersed buoyancy element, wherein the buoyancy fluid is a compound that is naturally in a gaseous state at ambient atmospheric temperature and pressure, and in a liquid state at the underwater depth to which the buoyancy element is immersed. A method is also disclosed for placing a buoyancy element in place between the surface and the bed of the sea, wherein fluid is stored in a tank on a surface ship as a liquid in the cooled or compressed liquid state, and is injected in the liquid state into a pipe from the surface where it is stored to an immersed casing at an underwater depth at which the underwater pressure is not greater than the vapor pressure of the gas corresponding to the compound at the temperature at the depth. | 01-13-2011 |
20110017117 | Floating Support Fitted with a Turret Including Rolling Bearings out of the Water - An oil production floating support including a disconnectable mooring system for anchor lines to the sea bottom and for bottom-to-surface connection pipes. The floating support comprises a mooring buoy for mooring lines and bottom-to-surface connection pipes, the buoy preferably being an annular buoy. The floating support being characterized in that said turret has a watertight tubular outer structure having a bottom wall assembled in watertight manner to the bottom end of the watertight tubular outer structure. The tubular outer structure contains an inner structure secured at its top end to the hull. The inner and outer tubular structures co-operate with at least one bottom rolling or friction bearing, enabling the inner structure to turn, with the outer structure not being caused to turn when the floating support is caused to turn about a vertical axis ZZ′ of the cavity and of the watertight tubular outer structure. The bottom rolling or friction bearing being situated beneath the surface of the water, but inside said watertight outer structure. | 01-27-2011 |
20110110724 | Floating Support Including a Turret Fitted with a Disconnectable Buoy for Mooring Bottom-to-Surface Connection Pipes - The present invention relates to an oil production floating support having a releasable mooring system of anchor lines to the sea bottom and of bottom-surface connection pipes, the support comprising: | 05-12-2011 |
20110260481 | GRIPPING DEVICE FOR GRIPPING UNDERWATER PIPELINES AT THE LAYING STAGE, AND RELATIVE AUXILIARY GRIPPING TOOL - A gripping device, for gripping underwater pipelines at the laying stage, has jaws that are pressed onto a pipeline extending along an axis substantially parallel to a laying direction, and have respective friction pads that are brought cyclically into contact with the outer face of the pipeline; and auxiliary gripping tools, which have panels for covering respective friction pads, and are selectively connectable to the jaws to increase grip between the jaws and the pipeline. | 10-27-2011 |
