Abstract: A watershed autonomous robotic data recorder maps subsurface topography and obtains water quality data for bodies of water. The device is capable of fully autonomous, manual, or hybrid navigation and includes a modular hull design which enables customization to accommodate both large and small bodies of water. A tangle-proof propulsion system is provided, to propel the hull(s). A deployable sensor pod includes a water sensor for determining if the sensor pod is in water, a pressure sensor for determining depth of the sensor pod, and a plurality of sensors for measuring water conditions. An onboard controller operates a winch that raises and lowers the sensor pod while the controller and a GPS receiver log positions of the sensor pod. This three-dimensional environmental, physical and chemical water quality attribute data collection creates a digital twin of the body of water to establish a common data environment for water modeling and analysis.

Abstract: A method of installing a subsea pipeline supports at least one elongate pipe stalk at the surface of the sea at a first, relatively shallow-water location by virtue of buoyancy added to the pipe stalk. The pipe stalk is then towed at the surface to a second location that is in deeper water. There, with the pipe stalk supported between leading and trailing towing vessels, at least some of the added buoyancy is removed. This causes the pipe stalk to hang with catenary curvature beneath the surface between the vessels. The catenary-curved pipe stalk hanging between the vessels is then towed to a third location for subsea installation, which may involve upending the pipe stalk before landing a lower end portion of it on the seabed.

Abstract: The present invention relates to the field of marine towing operations for marine seismic survey systems and seismic data gathering. More specifically, the present invention relates to seismic sources and receiver sensor cables, streamers, floats etc., that have means for adjusting and keeping a desired position in an array during a tow behind a vessel. The apparatus comprises a body (10) with means for being towed behind a vessel, means for connecting with and supporting and steering submerged marine seismic equipment laterally in the water and means for remote control from vessel. The body (10) of the apparatus has a forward positioned float unit (16) with an elongated rear float (12) hinged at the rear of the forward float. The forward float unit has vertical wings (18, 18′) with means for adjusting angle of attack in water.
