  • Patent number: 9381980
    Abstract: Systems and methods for launching and retrieving payloads in aquatic environments employ a platform that is both floatable and submersible at the discretion of and/or under the control of a user, on which submersible objects to be launched, delivered to a subsea location and/or retrieved (the payload) may be located. The platform is generally maneuvered to a desired site in a buoyant, floating state and is submerged, with the payload coupled to the platform, at the desired site. One or more buoyant elements is coupled to the submersible platform by cable(s), line(s), chain(s) or other coupling mechanisms. When the platform is submerged, the one or more floatable element(s) remain at or in proximity to the sea surface and support the platform in a submerged condition. The platform has a relatively large mass and, when submerged, acts as a dampener, while the buoyant element(s) and associated line(s)/cable(s)/coupling mechanism(s) act, relative to the submerged platform, as classic spring.

    Abstract: The invention relates to a concept for controlled containment of oil and condensate and possibly other types of liquids and chemicals in constructions as a possible failure of the conventional prior art barriers used in offshore petroleum exploration and production activities, intended for use at several water depths. The concept comprises a support structure (10) and a deck structure (14) positioned on top of the support structure (10), from where drilling may be performed, and where possible spillage of hydrocarbons from the drilling or production activities, in case of failure of the conventional barriers, will be contained and directed in a controlled manner to collecting storage tanks (46) integrated in the support structure (10).

  • Publication number: 20120189390
    Abstract: An Offshore Windpower Plant (OWP) includes wind turbine and foundation with the means that allow installing them by a new method that exclude the use of Jack up Crane Vessel. By this method, named OWP Technology, the completely assembled wind turbines would be lifted from the shore stand, using buoyancy force of Catamaran Wind Installer (CWTI), transported to the preinstalled foundation, engaged with it in a manner that would exclude CWTI from rolling and pitching and by this allow to use installed foundation as the base for stability for safe placing wind turbine on it. Thus would allow placing wind turbines on foundations regardless the depth of their installation. The CWTI does not need heavy lift revolving heavy lift crane it also does not need legs, thus makes it simpler, smaller and drastically less expensive that Jack up Crane Vessels.

  • Publication number: 20110305522
    Abstract: An arrangement and method for restraining surge and sway of the barge during floatover of a topside onto a substructure. Roller bumpers provided on the substructure guide the barge during slot entry and exit without the use of secondary mooring lines and restrain sway at the floatover position. Dedicated vertical bearing surfaces are provided on the substructure at the entry to the slot. Resilient bumpers are provided on the barge. The resilient bumpers engage the dedicated vertical bearing surfaces on the substructure and position the barge in the floatover position in the longitudinal direction. A tug boat tows the barge into the slot until the resilient bumpers engage the dedicated vertical bearing surfaces. The tug continues to pull throughout the floatover operation to hold the barge in the floatover position.

  • Patent number: 8070389
    Abstract: The present disclosure provides an improved method and system for loading a topsides onto an offshore structure by functional modules. A module support frame forms a supporting structure to which production modules can be assembled. The production modules are adapted to extract or process hydrocarbons from a hydrocarbon well in an offshore location. One production module is a well bay production module to which other production modules can be coupled, including a drilling support production module, separation production module, export module, and utility module. The module support frame can be loaded onto floating barges and other modules assembled thereto to allow the barges to provide incremental and controlled support during the loading process and for the floatover installation. The barges can be floated out to the offshore structure and loaded onto the offshore structure by methods including a floatover method or with a heavy-lift crane vessel.

It comprises deploying in the body of water (12) an intermediate section (30) of the pipe (24) from the downstream point (40) to at least as far as an upstream point (38), anchoring the upstream point (38), and tensioning the intermediate (section (30) to keep it vertical. The height of the buoy (26) is less than 1.5 times its greatest transverse dimension. The method comprises moving the buoy (26) between a remote position and an installed position in line with an anchoring region, keeping the buoy (26) partly submerged on the surface (16) of the body of water.

    Abstract: A tendon is assembled in a horizontal orientation using connectors or by welding at a weld station on a barge or other vessel located at or near the installation site of a tension leg platform. During assembly, the tendon is pulled away from the assembly vessel and tensioned by a tug or offshore work vessel. When fully assembled, the tendon may be up-ended in a manner similar to a wet-towed tendon, and then either pre-installed using floats or passed over to a TLP which is on-site and ready to receive tendons.

  • Patent number: 8016519
    Abstract: A method and system for transporting an offshore structure such as a wind turbine generator includes a supporting frame in which the offshore structure is assembled on land in an upright configuration. The frame is used for lifting the structure onto a transport vessel, on which it is retained in the upright configuration. At its location of use, the offshore structure is transferred to a pre-prepared foundation. The foundation is provided with a frame which cooperates with the supporting frame. The supporting frame includes a plurality of legs having hydraulically controlled feet. The frame of the foundation includes an equal number of supporting formations on which the feet ultimately rest. The feet are moveable in response to the hydraulic control along a nominally vertical line of action and provide a damping arrangement for the mounting of the offshore structure.

  • Publication number: 20110129301
    Abstract: A piling barge is disclosed by the present invention. In the piling barge disclosed, a supporting leg includes a supporting arm extended in vertical direction. Differing from the prior art, the supporting leg further includes a supporting base. The supporting base has a transverse section larger than that of the supporting arm, an end of the supporting arm is fixed with the upper surface of the supporting base. The supporting base of the supporting leg having a larger transverse section may receive support from a larger area of mollisol ground and thus provide a larger supporting force for the hull, which enables the piling barge to perform the piling operation on sea areas with mollisol ground. A piling device of the piling barge has pile frame adjusting mechanisms, such as a luffing oil cylinder, a luffing winch mechanism and a turntable, etc., which may adjust the incline angle and the position of the pile frame, therefore the working efficiency of piling operation of the piling barge can be improved.
