Abstract: A method of elevating the deck area of a marine platform (e.g., oil and gas well drilling or production platform) utilizes a specially configured sleeve support to support the platform legs so that they can be cut. Once cut, rams or jacks elevate the platform above the cuts. The sleeve support is then connected (e.g., welded) to the platform leg and becomes part of the structural support for the platform. In one embodiment, two sleeves are employed. In another embodiment, the jacks or rams elevate in two stages including a first stage wherein one sleeve elevates and the other sleeve does not elevate and a second stage wherein both sleeves elevate together.

Abstract: The present invention is an artificial surfing reef for modifying a body of water's bathymetry to create surfing waves. The artificial surfing reef is a shaped structure made up of many sized and shaped Expanded Polystyrene Geo Foam blocks. As swell moves toward the shore, its bottom is resisted by the leading edge of the Expanded Polystyrene Geo Foam artificial surfing reef. As the swell transverses over the Expanded Polystyrene Geo Foam Artificial reef, the wave topples over and forms a plunging surfing wave. An earth anchor, connected to a cable, linked to a round shaped anchor disc, is attached to each Expanded Polystyrene Geo Foam block for maintaining the foam artificial reef at a desired location submersed underwater. A plurality of Expanded Polystyrene Geo Foam blocks may be attached to one another and configured so as to define a surf reef, which enhances the suitability of waves for surfing.
