A mooring buoy reservation system is disclosed. The system comprises a mooring buoy that has the ability to enable or disable a tie up point on the buoy. The buoy has a microprocessor in communication with a server. And the server is in communication with a boat device. Also a method of a subscriber reserving a buoy through the server, paying for the buoy's use, and mooring to an enabled buoy is disclosed.

A deflector for a mooring buoy of the type having a raised shackle includes a mounting plate that has a top side, a bottom side, and at least one peripheral edge. A shackle aperture traverses a center portion of the mounting plate and is adapted for receiving the shackle therethrough. A cage projects upwardly from the at least one peripheral edge of the mounting plate and terminates at an upper rim. The cage has a plurality of apertures therethrough and two or more tie apertures adjacent the shackle aperture. In use, the shackle of the buoy is inserted into the shackle aperture and the cage is rotated 90-degrees to secure the deflector to the buoy. Ties are then fastened through the tie apertures and the through the shackle to further secure the deflector to the mooring buoy.

An energy farm comprising an electrical grid through which power generated by the devices in the farm may be combined and transmitted. The electrical grid is formed through the electrical interconnection of devices in a farm through electrical connections that remain, in whole or at least in part, adjacent to the surface of the body of water on which the devices float. A plurality of converters of the network have no direct or immediate electrical interface with a subsea power cable (i.e. a cable on or under the seafloor), but instead transmit electricity to other converters in a daisy-chained fashion.

A mooring buoy for a vessel comprises a floating body comprising a first portion and a second portion, wherein the first portion is rotatable with respect to the second portion. At least one anchoring line is connected between the second portion and the sea floor. At least one electric cable is mounted on the first portion and connected to a power supply. The at least one electric cable has a free end connectable to an electric circuit of the vessel. At least one mooring line is connectable between the floating body and the vessel. The mooring buoy comprises a cable length adjustment mechanism configured to adjust the length of the at least one electric cable when the first portion rotates with respect to the second portion.

A mooring buoy includes a first floating body, a second body slidingly connected to the first and normally submerged, a mooring line connected to the second body by a connector housed in a seat in the first body and movable between a retracted position and a protruding position, enabling fixing the mooring line. The buoy further includes at least one chamber, in one or both of the first and second bodies, a fluid circuit admitting fluid into and out of the chamber, and a control unit connected to the fluid circuit. The control unit controls the fluid circuit to vary the amount of the fluid in the chamber, causing a variation of the immersion depth of the first body with respect to the second body or vice versa and, consequently, movement of the connecting element between the retracted and protruding positions.

The invention relates to a system (2), having: a buoyant buoy (4), and a floating hose (6) which has a plurality of buoyant hose segments (8) which are coupled in series. The buoy (4) has a liquid outlet connection (12) which is connected to the floating hose (6), so that the floating hose (6) is arranged in a geometrical arrangement with respect to the buoy (4). A plurality of node units (18) are fastened in a distributed manner to the floating hose (6) and the buoy (4). Each node unit (18) is designed to establish, by means of an associated radio unit, a respective radio link (22, 24, 26, 28) to each of at least two of the further radio units of the respective node units (18, 42, 44, 46, 48), so that a radio network (30) is created. Each node unit (18) is designed to determine a relative distance (32, 34, 36, 38) from each further node unit (18) on the basis of the respective radio link. One node unit (18, 42, 44, 46, 48), which is designed as the main unit (40), is designed to collect the determined relative distances (32, 34, 36, 38) and to determine, on the basis of said relative distances, location data which represent the geometrical arrangement of the floating hose (6) relative to the buoy (4). The main unit (40) has a radio transmitter unit (50) which is designed to wirelessly transmit a location signal which represents the location data.

Systems and methods provide for offloading liquefied gas, e.g. liquefied natural gas (LNG), from a cargo vessel offshore and regasifying the offloaded gas. In example systems, a floating storage unit is moored to the seabed offshore; first tubing offloads liquefied gas from the cargo vessel to the storage unit; a jack-up platform is positioned offshore in proximity to the floating storage unit, the jack-up platform comprising legs which are arranged to be supported on the seabed and a hull which is arranged to be jacked up along the legs to a position above the sea surface; a regasification facility is provided on the jack-up platform; second tubing extends between the storage unit and the regasification facility of the jack-up platform for transferring liquified gas from the cargo vessel to the regasification facility for regasification of the liquified gas; and third tubing communicates regasified gas away from the regasification facility, e.g. to shore.
