Abstract: A disclosed subsea sediment separation and filtration system includes first and second separation devices, a spreader apparatus, and a storage device. The first separation device receives a water/sediment/oil mixture and from a subsea surface and separates the mixture into a first component containing cleaned sediment and a second component containing a water/oil mixture. The spreader apparatus disperses the cleaned sediment of the first component into a subsea environment of the spreader apparatus. The second separation device receives the second component from the first separation device and separates the second component into a cleaned water component and an oil component. The second separation device disperses the cleaned water component into a subsea environment of the second separation device and provides the oil component to the storage device. The first separation device may include a plurality of hydrocyclone devices, and the second separation device may include a high pressure hydrocyclone device.

Abstract: Systems and methods for surveying a seafloor utilize two or more of seismic data, acoustic data and electrical potential or resistivity data to identify the locations of objects on or beneath the seafloor. The methods involve moving survey equipment over a geographic area of the seafloor and conducting a plurality of sensing or detecting operations while moving the survey equipment over the geographic area. The plurality of operations include two or more of: (1) a seismic operation that emits seismic energy toward the seafloor and collects seismic data based on seismic energy that returns from the seafloor, (2) an acoustic operation that emits acoustic energy toward the seafloor and collects acoustic data based on acoustic energy that returns from the seafloor, and/or (3) an electrical operation that supplies electrical power into seawater and that collects electric potential data indicative of electric potential that is induced into the seawater.

Abstract: A system for dismantling submerged munitions is disclosed. The system includes a cleaning tool, a cutting tool, and a washout tool. The cleaning tool is configured to clean a surface of a submerged munition using a high-pressure water jet, and the cutting tool is configured to cut a hole in a submerged munition using a high-pressure abrasive water jet. The washout tool removes contents of the munition using one or more high pressure water jets. The system further includes a frame that houses the cleaning tool, the cutting tool, and the washout tool. The system may be lowered to the ocean floor and includes positioning mechanisms to position the cleaning tool, the cutting tool, and the washout tool relative to the munition to be dismantled. The system is configured to safely capture contents of submerged munitions to prevent release of the contents of the munition into the environment.

Abstract: Embodiments of the present invention include systems, apparatuses, and methods that include a pipeline inspection apparatus containing a carriage, a first member including at least a first and second sensor configured to take a first round of measurements of a pipe, a second member including at least a third and fourth sensor configured to take a first round of measurements of the pipe, and a multiplexer. The first and second members are attached to opposite side members of the carriage. The carriage, first member, and second member are configured to surround a section of the pipe and are movably mountable on the pipe. The multiplexer receives a signal from the at least first, second, third, and fourth sensors and creates a measurement signal.
