Abstract: An offshore system for petroleum production has a buoyant platform. A tendon assembly secures to the platform and extends down to a counterweight located near the lower end. A piling is embedded in the sea floor. A socket at the counterweight telescopingly slides over the upper end of the piling to prevent lateral movement of the platform. A dampening chamber is located between the socket and the piling. Ports for the chamber are arranged to allow a faster downward movement of the piling than upward movement.

Abstract: An apparatus controls the evacuation of volcanic magma to prevent explosions. Magma evacuation is through a single evacuation tube that heats the magma flow within the tube to prevent stickiness of the magma in the tube. The heating may use small combustion chambers to heat steam, which in turn heats and stabilizes the magma flow. Stability is aided by central cooling, where needed, using water jets from nozzles located at the wall of the tube.

Abstract: A soil reinforced retaining wall for an earthen formation is provided by embedding planar soil reinforcing mats in the formation at vertically spaced intervals and securing face mats between the soil reinforcing mats. The face mats include fingers extending distally from the edges thereof for engagement with opposite sides of a complimental face mat, whereby the mats are held in general vertical alignment. Certain of the fingers are of a gently curved configuration to frictionally hold edge portions of the face mats in spaced relationship for compression toward one another to accommodate settlement of the earthen formation, without bulging of the face mats. An L-shaped starter mat is engaged within a recess formed at the foot of the formation to provide an upstanding portion engaged with the lowermost is face mat to hold the mat in a generally vertical orientation. A tail is provided on the uppermost face mat for embedment within the backfill to cap the wall.

Abstract: A gas storage well with a tubing string that is disposed within a wellbore communicating an underground storage cavern with the surface. A surface controlled subsurface safety and flow control system is provided within the wellbore so that all flow into or out of the well can be shut down rapidly in the event of an emergency. The safety and flow control system features a dual opening-style packer element that provides an annulus seal between the surrounding casing and the tubing string and between the casing and a pup joint that is located within the annulus. Both the tubing string and the pup joint contain surface controlled subsurface safety valves that are capable of quickly shutting off flow through both the flowbore and the annulus. Each valve can be opened or closed independently of the other.

Abstract: A cushioning device as in a pillow that has a main-body foam which a plurality of projections extend off a surface of the main-body. The projections are arranged in different support characteristic groupings such as rows of different volume or sized projections (e.g., cylindrical, cubical, prismatic, etc.) spaced out over a surface (e.g., convex surface) of the pillow (one or more surface sections as in upper surface sections and front edge surface section). There is also preferably provided a neck support ridge extension. The cylindrical projections are arranged such that a greater number of smaller volume, width or diameter, etc. rows of projections are centrally positioned on the surface and with the larger volume, width, or diameter, etc. projections laterally outward of the more centrally positioned projections, and with the ridge extension preferably extending along a front edge (e.g.

Abstract: A method for deploying a floating platform includes storing buoys on a hull of the platform. Tension devices are mounted to the hull, each being connected by a line to one of the buoys. The operator tows the hull to a ballast down site while the buoys are stored on the hull. While adding ballast to the hull, the operator feeds out the lines from the tension devices at a selected tension. The hull moves downward in the water while the buoys float at the surface to maintain stability during the ballasting. The buoys are detached from the lines after the hull is ballasted to a desired depth.

Abstract: A maritime unit and a method for operating a maritime unit. The maritime unit includes a frame structure. The maritime unit includes at least three legs moveable between a standby position and an extended position. A jack mechanism moves the legs between the standby position and the extended position. The maritime unit has at least its legs operated on a disk brake principle for enabling a substantially stepless drive therefor, whereby the maritime unit has each of its legs provided with a brake system, including one or more brake flanges extending longitudinally of the leg. The maritime unit has its frame structure provided with a brake system including one or more brake shoe elements operable in a vertical direction with the jack mechanism.

Abstract: A modular pier includes a plurality of modular pier sections. The plurality of modular pier sections includes at least a first pier section and a second pier section wherein the pier sections include a frame having a first end and a second end opposite the first end.

Abstract: A double walled riser sump has an annular space between the two walls. The provision of the annular space provides for monitoring the integrity of the two walls of the sump. The two walls of the sump are preferably separated by a thin film or a distance fabric that allows the passage of fluids, and preferably liquids. The annular space may be in fluid communication with a reservoir holding a monitoring fluid and positioned near the top of the sump to be easily accessible. In some embodiments, a top of the riser sump is also double walled and the top annular space is in fluid communication with the annular space between the vertical walls. If a leak develops in either wall of the sump, a corresponding drop in the fluid level of the reservoir will occur.
