  • Apparatus and method for soil testing for jack-up rigs
    Patent number: 8146418
    Abstract: An apparatus for soil testing for a jack-up rig, the apparatus comprising a soil testing device integrated with a leg of the jack-up rig, the leg of the jack-up rig having a footing, an opening in the footing for allowing passage of an active portion of the soil testing device therethrough to obtain soil data from a seabed beneath the footing, and a retrieval assembly for retrieving the soil testing device.

  • Offshore foundation system with integral elements for preloading and extracting
    Patent number: 8025463
    Abstract: The present invention describes an offshore foundation system (10,10a,10b) that is operable for preloading after self-weight installation on a seabed without relying on additional or external ballasts. The foundation system (10,10a,10b) is also operable for extraction by reversing the process of preload operation. In one embodiment, the foundation system (10) comprises a reaction base (20) and suction compartment (60). In another, the foundation system (10a,10b) comprises a plurality of units of reaction base (20) and suction compartments (60), with the units being connected by bridging structures (21). In yet another, the foundation system comprises a reaction base (20) and a plurality of suction compartments (60). A closed-top of the suction compartment (60) projects above the reaction base (20) so that, in use, there is a gap h between a top of a soil plug inside a suction compartment (60) and its closed-top.
