Abstract: A system and method of creating, operating and maintaining a hydrocarbon storage facility in a salt cavern within an underground salt deposit. The system is portable and can be transported to areas near different well heads. The portability also enables adjacent well heads to be worked in succession to create a large storage cavern by interlinking a series of smaller caverns. This formation processes ensures that a storage cavern can be isolated within the confines of a salt deposit. Using the same portable equipment, the system can be configured to form a salt cavern, displace stored material out of a salt cavern, and repair or maintain a salt cavern well.

Abstract: A transportation device for an offshore platform, including a vessel and a floating structure which are fixedly connected. The floating structure is placed on a sea surface and is configured to assist the vessel to sail. The floating structure is provided with an adjustment mechanism which is configured to adjust the floating structure to rise and fall relative to the sea surface. A rail is arranged on the vessel and is in sliding connection with the topside module, so that the topside module slides onto the vessel from land. During the transportation of the topside module, the buoyancy of the floating structure is adjusted through the adjustment mechanism, so that the floating structure provides sufficient anti-rolling moments beside the vessel, thereby reducing the vibration of the topside module caused by the winds and waves during the sailing and reducing the potential damage to the topside module.

Abstract: A rapid construction method of pipe jacking for underground rescue tunnel with large section is disclosed. The present invention realizes rock breaking through the cutting head of a roadheader cutting unit, and pushes pipe jacking forward through a pushing thruster. During the process, a protecting bush fixedly connected with a stretchable part is adopted for circumferential support; and since the cutting head and the protecting bush occupy the rock breaking space, and the pushing thruster pushes pipe jacking forward to push the coal rock in the annular space to the circumferential direction, the effect of moving forward without slag discharge can be achieved. The present invention can establish a rescue tunnel quickly and effectively, which saves rescue time and greatly reduces the threat to the life safety of trapped people. The present invention can establish a fast and safe underground rescue tunnel with large section for the rescue of people.

Abstract: A monolithic manhole is formed in a levee without trenching, to provide access to drain pipes within the levee for maintenance and repair of the pipes. The manhole is formed by first forcing an outer tube downwardly into the earth and levee and removing soil from within the outer tube to expose the pipe. An inner tube is lowered into the outer tube, with an annular space maintained between the tubes. The annular space is filled with concrete, which hardens to form a monolithic vertical wall. A concrete floor may be poured at the bottom of the wall and a cover attached to the top of the wall. A hole is cut in the pipe inside the wall to provide internal access to the pipe.

Abstract: Mooring chains used in offshore environments are typically formed from carbon steels due to their wear and fatigue resistance properties. Although carbon steels may exhibit robust mechanical properties, they are susceptible to corrosion, which can shorten the usable working lifetime of mooring chains, particularly in a seawater environment. Austenitic steels comprising high percentages of manganese may have comparable mechanical properties to the carbon steels commonly used in mooring chains, yet exhibit less susceptibility to corrosion. Austenitic steels suitable for use in mooring chains and other structures in contact with or exposed to a seawater environment may comprise: 0.4-0.8 wt. % C, 12-25 wt. % Mn, 4-15 wt. % Cr, a non-zero amount of Si<3 wt. %, a non-zero amount of Al<0.5 wt. %, a non-zero amount of N<0.1 wt. %, <5 wt. % Mo, and balance Fe and inevitable impurities.
