摘要： A jetting system for an undersea trencher has jetting conduits extending aftward of its trench-cutting jetting swords. Jetting conduit nozzles direct liquid radially from their jetting conduits into the trench after the trench is excavated by the jetting sword cutting nozzles. The jetting conduits direct sufficient liquid into the trench to maintain the mix of trenched soil and water in the trench along the length of the conduits at not more than a super-critical density, extending the distance in which the product being laid in the trench is able to descend in the trench and increasing the likelihood that the product will be buried at the intended trench depth.

摘要： This invention relates to hydraulic engineering construction and can be used for deposit cleanup of river beds and channels. The object of the invention is to expand the arsenal of usable means for deposit cleanup and deepening of river beds, develop a method and create a device that uses the speed of the river current in the most effective way. The technical result of the claimed method is simplification and optimization of one existing method for cleanup of river beds and channels, increasing its functionality. The proposed method implements a movable water flow-restricting device with flow-guiding elements that creates a concentrated stream and directs it to a washout zone, bound by side walls, roof and washout surface.

摘要： A BAS plow creates a V-trench along the linear route of a pipeline path and an instrumented bottle moving with the BAS plow collects BAS data indicative of the pitch, roll, heading, yaw, three dimensional positioning, speed and depth of the chassis, the shearing force applied to the seabed material and the applied tow force. The bottle can be swapped to collect the acquired data or an umbilical can be used to provide a real time stream of data. The Bas plow can simultaneously backfill the created trench, leaving an undisrupted seabed, or the pipeline can be laid in the BAS trench, which can also be made deeper and wider by additional trench cutting passes, significantly reducing the total time required for combined BAS and pipeline laying processes. The BAS plow can be released and retrieved over-the-stem of a towing vessel.
