Abstract:
A system for monitoring a remote underwater location using an unmanned underwater vessel (5). The system includes an unmanned surface vessel (8), a communication unit (7) for submerged location and connected to the unmanned surface vessel (8) and in which the unmanned surface vessel has a position tracking control system for controlling the position of that vessel on a body of water and relative to the unmanned underwater vehicle (5). The communication unit (7) has a first wireless communication arrangement for communication with the unmanned underwater vehicle, a second wired communication arrangement (10) for communication with the unmanned surface vessel and the unmanned surface vessel has a third communication arrangement for communication with an operator or observer (1) remote from the unmanned surface vessel and the unmanned underwater vehicle. The three communication arrangements are arranged in series such that, in use, the operator or observer may communication with the unmanned/autonomous underwater vehicle via the unmanned surface vessel, the wired connection between the unmanned surface vessel and the communication unit, and the wireless connection between the communication unit and the unmanned underwater vehicle
Abstract:
A system with an underwater vehicle for installation and de-installation of buoys (9) under sea level (6). The vehicle (10) comprises a buoyancy adjustment system (19) for continuously adjusting the buoyancy of the vehicle (10) during underwater operation. A gripper (24) is connected to the vehicle frame (10′) by an orientation adjustment mechanism (29, 30, 31) for adjusting the gripper (24) orientation when installing a buoy (9) onto a flexible underwater line or for deinstalling the buoy (9) therefrom. The vehicle (10) further comprises a controller for manoeuvring and operation.
Abstract:
A power management system comprises a remotely operated vehicle (ROV), a tether management system (TMS), and an umbilical operatively in communication with the TMS external electrical power interface and the TMS-to-ROV umbilical interface. The system can be configured to provide electrical power management that moves some or all of the electrical power required for ROV propulsion and tooling to the ROV and/or TMS, and maximizes available power and manages loads across all systems as necessary and by priority. Power management may also be required that features intelligent routing of power to subsystems and integration of variable frequency drives (VFDs).
Abstract:
Device for cleaning a submerged surface (12) of a vessel (7) or similar, whereby the device (3) is provided with a cleaning module (2) with at least one rotating brush (11) which, upon the movement of the cleaning module (2), ensures that the cleaning module (2) is pushed or sucked against the aforementioned surface (12), characterised in that the device (3) is further provided with a launch platform (1) that can place the cleaning module (2) against the aforementioned surface (12) and which is connected thereto by means of a first cable (15) for the control of the cleaning module (2), whereby this launch platform (1) is provided with at least one camera (4) and a drive (8) to move the launch platform (1) underwater, whereby the launch platform (1) is connected to means (16) to bring the launch platform (1) to a desired location underwater, whereby the launch platform (1) is connected via a second cable (5) to a control unit (6) for controlling the launch platform (1) and the cleaning module (2).
Abstract:
A system for controlling a subsea device comprises a complimentary set of data communication interfaces operatively coupled to an electronically interrogatable component of a subsea device and a remotely disposed device controller via a power conductor which defined data pathway between the subsea device and the remotely disposed device controller. A data transceiver is operatively coupled to the electronically interrogatable component and the remotely disposed device controller via the complimentary set of data communication interfaces over the power conductor. In configurations, control and/or telemetry or other data may be unidirectionally and/or bidirectionally transmitted between the electronically interrogatable component of a subsea device and a remotely disposed device controller. In configurations, data faults may be monitored in a primary data path and, if a fault detected, control and/or telemetry or other data transmission switched to the power conductor data pathway, manually and/or automatically.
Abstract:
Machinery and methods are described whereby a free flying, remotely operated vehicle (ROV) can safely capture and take on board lightly managed seismic sensor devices (payload) while they are in-transit via a surface vessel in a (deep) water column. ROV payload can be replenished without the need for the ROV to return to the surface vessel to receive additional payload and to do so without the need for heavy launch and recovery machinery. The reverse process of returning payload from the ROV to the surface vessel is also disclosed.
Abstract:
Die Erfindung betrifft ein Schutzgehäuse 10 für einen Propeller eines Unterwasserfahrzeugs. Die Erfindung betrifft außerdem ein Verbindungssystem für ein propellergetriebenes Unterwasserfahrzeug mit einem Verbindungskabel und einem solchen Schutzgehäuse. Ferner betrifft die Erfindung die Verwendung eines Schutzgehäuses 10 für einen Propeller eines Unterwasserfahrzeugs zur zugentlasteten Aufnahme eines Verbindungskabels 5. Um mit geringen Herstellungskosten eine Verbindung zwischen einem propellergetriebenen Unterwasserfahrzeug und einer Trägerplattform mittels eines Verbindungskabels 5 zu ermöglichen, welche strömungsgünstig ist und eine zugentlastete Aufnahme des Verbindungskabels 5 gewährleistet, ist erfindungsgemäß an der außerhalb des vorgesehenen Arbeitsbereichs des Propellers 2 um eine Propellerachse 3 liegenden Peripherie des Schutzgehäuses 10 eine zugentlastende Kabelaufnahme 16 für ein Verbindungskabel 5 des Unterwasserfahrzeugs 1 angeordnet.
Abstract:
This invention provides a vessel system and methodology that can be used to promote growth of phytoplankton in the oceans. Unmanned self-controlled wave-powered vessels are equipped with storage units for dispensing a fertilizer, and with sensors to monitor ocean conditions and effects. Fleets of vessels move autonomously by on-board processing of GPS and directional information, piloting a path that is coordinated by a central processing unit. The vessels travel through a defined target area, creating a detailed survey of chemical and biological characteristics that affect grown. The data are processed in a computer model to identify precise locations and precise amounts of fertilizer that will produce the best results. Projected benefits of fertilizing plankton include sequestering CO2 from the atmosphere, and enhancing the marine food chain to improve the fish stock in and around the treated area.
