摘要:
A vessel docking system has a vessel such as a scow and/or a tugboat, a platform such as a barge and/or a dredger, an optical distance measuring means, a vessel display unit, and a control means. The vessel display unit is configured to display a position and a location of the vessel and/or the platform. The optical distance measuring means is in communication with the vessel display unit. The optical distance measuring means includes a sensor, a laser, and lens. The optical distance measuring means is configured to determine a distance and a pathway between the platform and the vessel.

A method for determining a displacement of an anchor is provided. The method includes the steps of: determining an initial position of the anchor; and determining a displacement of the anchor. The step of determining the displacement of the anchor includes (i) measuring anchor velocity values, (ii) measuring at least one further physical quantity associated with the anchoring, (iii) deciding whether the anchor is at rest or in motion, wherein a value of the further physical quantity is taken into account in the decision, and (iv) integrating the velocity values over time during intervals when the anchor is deemed to be in motion.

A mooring buoy comprising a buoyant body, an attachment point for attaching the buoy to a marine vessel, a controller, an RF communication device for receiving a vessel ID identifying the marine vessel and a movement sensor, wherein the controller is arranged to determine when the marine vessel is moored to the mooring buoy based on the received vessel ID and the movement sensor.
摘要:
An apparatus and method for control of at least one of a plurality of semiautonomous marine vessels are provided. The system includes a control station with a communications system for network communication with marine vessels, and provides diagnostics and control for control and monitoring of the marine vessels, according to a mission plan.
摘要:
The present invention relates to a black box system for a leisure vessel and, more particularly, to a black box system for a leisure vessel which has a marine black box to interface a GPS receiving unit with various kinds of navigation data measuring devices and a camera unit, thereby checking problems in the vessel in real time, and which executes information stored in a portable memory with a marine black box application via a smart terminal to output the information on a display screen and to simultaneously store images and data at the time of an accident in a data storage server provided on land, thereby increasing portability and analyzing navigation data and images for a vessel when the vessel has been lost due to an unexpected accident.
摘要:
A seismic survey system records seismic signals during a marine seismic survey. The system includes at least two underwater bases and plural autonomous underwater vehicles (AUVs) that carry appropriate seismic sensors. An AUV is housed by an underwater base and it is launched to a final destination from the underwater base. The AUV receives pinger signals from at least two underwater bases for correcting its trajectory toward the final destination.
摘要:
A watercraft includes a watercraft body, a watercraft propulsion device, a water protective case, a communication device, and a display device. The watercraft propulsion device propels the watercraft body. The water protective case is arranged on the watercraft body. The communication device communicates with a mobile terminal arranged inside the water protective case. The display device displays content of the mobile terminal based on data received from the mobile terminal through the communication device.
摘要:
A portable towed vessel suitable for containing and transporting various liquids is disclosed. The vessel further comprises various features useful in navigation and storage of the device, both when in use for transporting fluids and when transported in an emptied state. Such features include navigational and positioning devices and methods, and means for emptying and deflating a towed vessel. Aspects of the present invention further include the ability to quickly fill and evacuate a towed vessel and features useful for purifying or preserving the purity of fluid to be transported.
摘要:
A submarine (1) includes a bridge (4), a bridge fin (3) and a device (8) for releasing and recovering a secondary self-propelled underwater vehicle (90). The device (8) includes a handling element (8A) which can be used to move the secondary underwater vehicle between a storage zone (18) and a release or recovery zone (19) and a reversible grip element (14) solidly connected to the handling element (8A), which can be used to free the secondary underwater vehicle (90) at the moment of release and to attach the vehicle at the moment of recovery. The release and recovery device (8) is designed such that the release and recovery zone is located outside the turbulent zone (7) that surrounds the moving submarine.
摘要:
An extendable spar buoy sea-based communication system includes a spar buoy having a retracted configuration deployable from an underwater vessel and an extended configuration after deployment, and a communication subsystem mounted to the top of the spar buoy and supported thereby.
