  • Methods and apparatus for protecting offshore structures
    Patent number: 8641327
    Abstract: Protective structures for offshore installations and methods for using same are provided. The protective structure can include a body adapted to be disposed at least partially about a primary structure of an offshore installation, and a support system can be disposed on the body. One or more protrusions can be disposed about an outer surface of the body. The protrusions can have a first end adapted to break ice. The support system can be adapted to isolate the one or more bodies from the primary structure such that the one or more bodies can absorb at least a portion of ice generated vibrations.

  • Subsea hydraulic and pneumatic power
    Patent number: 7963335
    Abstract: Systems and methods for providing energy to sub-sea support equipment. Energy can be provided by diverting at least a portion of a fluid from a well producing system to sub-sea support equipment units that can be disposed in the vicinity of the sea-floor, sea-bed, or mud-line. The well producing system can include, but is not limited to, a water injection system, a gas lift system, or combinations thereof. A water injection system designed to provide pressure support to one or more wells can be modified to provide an operational power source to one or more sub-sea support equipment units.
