Abstract: An artificial soil structure includes a water shield layer provided on a soil layer, the water shield layer includes water repellent sand processed by water repellent treatment. A water retentive layer is provided on the water shield layer, and the water retentive layer includes water retentive sand with no water repellent treatment. A water repellent soil body is provided in part of the water shield layer so as to penetrate the water shield layer and be in contact with the soil layer and the water retentive layer.

Abstract: A water repellent sand layer that is made of water repellent sand and serves as a water shield layer is provided to be slanted between upper and lower soil layers, a water conveying belt portion is provided to include at least one or both of gravel and a culvert that are provided between the water repellent sand layer and the upper soil layer, and a water shield wall is provided at a slant downstream side. Water falling and permeating from a ground surface into the soil layer is blocked by the water repellent sand layer, flows downward in the water conveying belt portion located above the water repellent sand layer to the slant downstream side, and is blocked by the water shield wall at the slant downstream side, so that the collected water is recovered from a drain hole in the culvert that penetrates the water shield wall.

Abstract: A method for pipe laying, includes the step of vertically forcing a generally rigid pipe section in a substantially vertical direction downwards from a position above ground towards a desired pipe section position in the ground, wherein the pipe section maintains a substantially horizontal position upon forcing the pipe section downwards. The vertically forcing a generally rigid pipe section in a substantially vertical direction downwards is beneficial for pipe laying because time consuming digging of a slit is not required anymore.

Abstract: A method of deploying a containment boom is provided whereby an elongated material, such as a sheet, yarn, or yarn bundle, is formed into a roll and the material is pulled from the interior of the roll to create a helical structure. A pull rope is threaded through the interior of the roll and is deployed along with the material, such that the material is wrapped around the pull rope. The pull rope prevents the boom from stretching and distorting the helical structure formed by the material, as well as preventing the material from self-wringing. Multiple rolls of material may be provided in a single boom package arranged in coaxial alignment. When the materials are connected in parallel, they are integrated into a single boom having concentrically wrapped materials, thereby providing for greater stability and functionality.

Abstract: A vibratory compaction plate utilizes pairs of front and rear shock absorbing mounts, each pair of which is set at a different angle with respect to the horizontal plate to optimize the respective shear and compression capabilities and optimize performance. A front mounted vibratory exciter and a rear mounted engine provide different performance capabilities that are optimized by the mounting angles. A flat sheet metal plate and sheet metal frame permit the angles at which the shock mounts are oriented to be adjusted along laterally extending end lines to fine tune performance.

Abstract: Systems and methods for unearthing, retrieving, and processing subsea tubulars can include engaging a cable to an end of a subsea tubular and a vessel, moving the vessel in a direction parallel to the axis of the tubular, and unearthing the tubular using the thrust of the vessel. Unearthed tubulars can be dragged to a remote location, retrieved to the surface for transport or processing. On-site processing can be performed using a tensioning device to continuously move a tubular into association with a cutting device, which severs a first portion of the tubular while a second portion remains engaged with the tensioning device.

Abstract: A method of remediating contaminated sediment area. The sediment has an initial water depth and comprises water and fine-grained solids. The contaminated sediment is contained in place by installing over the contaminated sediment an in-situ cap having a total thickness TCP. The contaminated sediment, and optionally any uncontaminated subsurface, is then consolidated until the total settlement of the contaminated and uncontaminated sediment exceeds the thickness TCP of the in-situ cap. The sediment is consolidated by installing a vertical barrier along the perimeter of the contaminated sediment area, installing a plurality of horizontal line drains into the sediment, connecting the horizontal line drains to a vacuum source, installing an in-situ cap over the contaminated sediment area and over the upper edge of the vertical barrier, and applying vacuum pressure to the horizontal line drains to dewater and consolidate the sediment.

Abstract: A jackable building foundation system includes a steel beam support frame platform to which one or more platform jacks are attached. Vertical movement of the platform in response to jacking is constrained by cuboidal column guides at the four corners. Each of the column guides comprises two tiers of square roller frames, within each of which is an I-beam engaged between the flanges on either side by two rollers supported on horizontal axes. The orientations of the I-beams and rollers alternate orthogonally at each corner of the platform, so that torques generated by uneven jacking are suppressed and do not result in jamming of the platform as it rises. The system is remotely controlled and monitored by a digital device, such as a smartphone, using application software.
