The present invention provides a lateral and continuous measurement method for soil parameters in a soft soil field. The method mainly comprises the following measurement steps: arranging soil strength measuring apparatuses at the front end of a towing apparatus; arranging soil strain softening relationship measuring apparatuses at the bottom end of the towing apparatus; and measuring interface friction parameters between the soil and a structure. The towing apparatus actively or passively moves in a soft soil layer to ensure that the towing apparatus partially penetrates into the to-be-measured soil layer during movement; and the penetration depth of the towing apparatus is controlled by adjusting counterweight above the towing apparatus and a towing angle.

A foil for a towed cable includes a body defining at least two conduits. The body has a foil shape having a leading edge and a trailing edge. The foil shape defines a first surface extending between the leading edge and the trailing edge configured to provide lift. The foil shape defines a second surface opposed to the first surface extending between the leading edge and the trailing edge. The foil shape defines first and second lateral sides that extend between respective lateral edges of the first and second surfaces, the leading edge, and the trailing edge. A first conduit is defined within the forward half of the body adjacent to the leading edge, is open to each of the first and second lateral sides, and is configured to receive a cable therethrough. A second conduit may be defined within the body and filled with buoyant material.

A field configurable autonomous vehicle includes modular elements and attachable components. The vehicle can be assembled from these modular elements and components to meet desired mission and performance characteristics without the need to purchase specially designed vehicles for each mission. The vehicle can include a mechanisms that magnetically attaches to a ferry vehicle for transport to the location of use.

A docking system has flat funnel and a slotted ramp at the end of the flat funnel. The slotted ramp has a plurality of inclined planes, each on a respective side of the slot. A docking adapter, fitted over an underwater vehicle, includes a guide plane and a mask. The flat funnel guides the guide plane to the top of the ramp during docking, so that the underwater vehicle may be charged. Another aspect of the invention is a highly maneuverable glider including a forwardly mounted buoyancy module followed a pitch module, followed by a processing module, followed by a roll module, mounted concentrically with respect to each other. The glider may be attached to any docking system, not just that of the present invention. When used in conjunction with the docking system of the present invention, the glider may be attached to either the flat funnel or the docking adapter of the docking system of the present invention.

A catch handling system includes a catch collection system. The catch collection system includes one catch handling depot; one or more trawls; and a catch transport system, where the catch transport system includes a transport system, and where the transport system includes a transport node. The transport node includes a releasable connection to a catch handling fleet carrier drone and to one or more units of a catch handling fleet.

A docketing device includes a docking station able to be hauled by a carrying vessel at a tow point (T), the docking station comprising a body comprising a beam extending parallel to a longitudinal axis (x) of the body and a stop allowing a movement of an underwater vehicle with respect to the body along the longitudinal axis (x) to be blocked, the dorsal beam extending longitudinally above the underwater vehicle in abutment against the stop, a center of gravity of the docking station and a center of buoyancy of the docking station being positioned, and the tow point (T) being able to occupy a docking position that is such that the docking station exhibits a predetermined docking negative pitch when it is fully submerged and hauled by the carrying vessel in the direction of the longitudinal axis at a predetermined speed.
