Abstract: Techniques and systems to reduce deflection of a riser extending from offshore platform. The riser may be coupled to a seafloor and may experience movements due to, for example, currents. A riser restraint device may be utilized to reduce these movements of the riser. This riser restraint device may be coupled to the seafloor. This coupling of the riser restraint device may aid in allowing the riser restraint device to reduce movement of the riser and, thus, reduce deflection of the riser.

Abstract: The disclosed subsea clamp tensioning system includes predictability of gasket pre-load to input closure and allows a subsea clamp tensioning system to be closed and made-up without the hindrance of frictional loads that will cause a loss of tension in a drive screw. In an embodiment, the subsea clamp tensioning system tensions the drive screw by applying a set torque load into an API class torque bucket which translates into an applied tension at the drive screw. The tension load on the drive screw applies the gasket pre-load required to create a metal-to-metal seal between the two clamp hubs. Once complete and tested, the subsea clamp tensioning system may be removed and mounted onto a connector tool for retrieval to the surface.

Abstract: In a cold planer, a rotor housing partially enclosing a rotor may have a rotor housing side wall with retention plates defining a space in which a rotor housing side plate disposed so that the side plate can translate and rotate relative to the rotor housing. A pair of side plate lift cylinders may operate to vary a vertical position of the rotor housing side plate and a rotation of the rotor housing side plate about a horizontal axis relative to the rotor housing. The cold planer may use information from one or more distance sensors to identify contours in a work surface over which the cold planer is propelled, and actuate the lift cylinders to adjust the position and orientation of the rotor housing side plate to closely track the contour of the work surface and substantially prevent ground material from escaping from the rotor housing.

Abstract: The present invention relates to an open pit mining system. The system includes a material lifting machine configured to both: (1) excavate and remove overburden from an open pit of a mine; and (2) excavate and remove valuable material from the open pit. Advantageously, the machine removes the overburden waste material as well as the mined valuable material which would otherwise be conventionally removed by trucks in the pit, out of the pit up the ramps and then onto the processing plant. Accordingly, the use of trucks for transporting valuable material both along and up out of the pit is at least to some extent reduced thereby resulting in improved cost and energy efficiency.

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.
