Publication number: 20130315677Abstract: In order to board a fixed structure, ocean conditions must be within a reasonable state that allows personnel to board in a safe manner. Due to the specific weather conditions, the boarding of fixed structures cannot be conducted. Both oil and gas and wind platforms must be boarded for maintenance and repair purposes. The invention allows boarding of fixed structures employing three buoyant vessels that can be adjusted to always be heading into the wind direction. Landing piles are pre-driven adjacent to the fixed structure and terminate at the ocean bottom. The invention has three deployable legs that extend through the buoyant vessel to the ocean bottom. The placement of the driven supports employs the same dimensions as the spacing of the vessel's extension legs. The vessel operator adjusts the heading of the three buoyant vessels to the wave heading. The legs are extended to the ocean bottom.Type: ApplicationFiled: May 1, 2013Publication date: November 28, 2013Inventor: Herman Joseph Schellstede

The hull is specifically shaped with an ice-bending surface to bend and break up ice that comes in contact with the hull while in the ice defensive configuration.Type: ApplicationFiled: October 21, 2011Publication date: May 24, 2012Applicant: ConocoPhillips CompanyInventors: Peter G.

Patent number: 7921604Abstract: An aluminum-foam structural housing unit that is storm-proof, self-contained, and built to withstand natural disaster conditions resulting from hurricanes, tornadoes, earthquakes, and fire, and then assist its inhabitants immediately thereafter when interruptions in public utility system service can be experienced. The combined use of aluminum alloy and foam as its building materials gives the unit its great strength, as well as the versatility needed to face natural disaster conditions while providing absolute resistance to heavy winds, flooding, earthquake and fire. Since the unit is buoyant, during flooding conditions it lifts from the ground and is guided by vertical poles to maintain a horizontal orientation. The unit also automatically disconnects from public utility systems as lifting occurs, and it then provides its inhabitants with self-contained sources of water, electrical energy, and sewage management. Thus, the unit is designed to adjust to the flow of nature, instead of working against it.Type: GrantFiled: January 4, 2006Date of Patent: April 12, 2011Inventor: Siaosi Kaihau Lino

Publication number: 20110044763Abstract: 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.Type: ApplicationFiled: August 23, 2010Publication date: February 24, 2011Inventors: Jon Khachaturian, E.
