摘要： The body component and the protector component are inserted into the through hole of the end face plate. The protector component is disposed, in the through hole, at a place closer to the outer surface of the end face plate than the body component is. The body component guides a tail cable into the internal space of the pressure-resistant housing main body. The protector component protects the tail cable. The nut fixes the protector component to the end face plate. The elastic member is attached to the end face plate so as to cover the boundary part between the protector component and the nut. The insulating liquid is charged in the space between the elastic member and the protector component.

摘要： Disclosed is a measurement system for aquatic environments, including a surface vessel and a submersible device, the submersible device including a hull, propulsion, guide, and sensors for taking measurements. The submersible device can either be launched from the vessel in order to then maneuver underwater independently of the vessel during a remote deployment phase, or be stored in a vessel during a non-deployment phase, the vessel including at least one hull and propulsion and guide, the at least one hull of the vessel including a submerged portion located below a waterline. The submerged portion of the at least one hull of the vessel includes a recess designed to receive at least an upper portion of the hull of the submersible device when the latter is stored in the vessel, the recess being arranged entirely below the waterline so that the submersible device remains completely submerged during storage.

摘要： A method of hosting an autonomous underwater vehicle (“AUV”) at a subsea location lowers at least one AUV basket to a subsea location adjacent at least one preinstalled subsea structure. The subsea structure has provision for electrical power to be provided to it. At the subsea location, the, or each, basket is connected to the, or each, subsea structure to receive electrical power from the subsea structure. Electrical power routed via the subsea structure may be used to charge batteries of an AUV docked with the basket. Provision may also be made to effect data communications with the AUV with data being communicated between the subsea structure and the basket.

摘要： A current detection sensor is disclosed. The current detection sensor comprises a current probe configured to connect to a remotely operated vehicle (ROV). The current probe comprises a low reluctance core configured to selectively enclose about a conductor in response to an actuation of the ROV. A gauge comprising a gauge control circuit is in conductive communication with an input and an output of the current probe. The gauge controller is configured to identify transmission data for the conductor based on a detection routine. The detection routine comprises supplying an input signal to the input and monitoring a voltage at the output. Based on the voltage, the routine identifies electrical properties of the current transmitted through the conductor.
