The monitoring means are connected to an acoustic modem (5, 8) arranged to transmit the anchor condition data to the vessel and/or another involved vessel (9). One acoustic modem (8) may be arranged to transmit the anchor condition data to the vessel and/or another involved vessel (9) via a wireless transmission path. Another acoustic modem (5) may be arranged to transmit the anchor condition data to the vessel (1) via the interconnection line (3). More in general a system is disclosed for data transfer between two objects (1) which are mechanically interconnected by an interconnection line (3), each object including an acoustic modem (5) which is arranged to transmit and/or receive data via the interconnection line.
Description
- The invention refers to a mooring system for a vessel, including a mooring anchor and an interconnection line for connecting the anchor to the vessel. Within the scope of this document the concept of interconnection line is deemed to include any type of line, cable etc. arranged to interconnect objects like vessels, buoys, anchors etc. especially, however not exclusively, in oceanic and/or deep-water environments. Such interconnection lines may be called mooring lines or mooring cables.
- In ocean engineering, for instance, safe mooring of structures like floating off-shore platforms etc. is crucial.
- One aim of this invention is to provide a mooring system in which an anchor -which can be located several hundreds meters to a few kilometers from the anchored vessel, e.g. an oil or gas platform- is enabled to pass information related to, but not limited to, e.g. the anchor's position, its orientation angle, depth under the seafloor etc.- to a platform or any other involved vessel to which it is connected.
- Another aim of this invention is to provide a mooring system in which the anchor part is able to communicate with any involved vessel via an interconnecting interconnection line.
- Still another aim of this invention is to use a cable like an interconnection line or cable as a transmission medium for exchanging data.
- Yet another aim of this invention is to interconnect acoustic modems via an interconnection line or cable, whereas acoustic modems are normally used as wireless communication devices for transmitting data and information through the ocean. Within the scope of this document the concept of acoustic modems are deemed to include acoustic transceivers and acoustic transmitters or receivers respectively, especially, however not exclusively, arranged for transmitting and/or receiving data in oceanic and/or deep-water environments.
- According to the invention a mooring system for a vessel is provided, including a mooring anchor and an interconnection line for connecting the anchor to the vessel, wherein it is preferred that the anchor comprises and/or is linked to monitoring means arranged for monitoring the anchor's condition and for outputting anchor condition data, and wherein the monitoring means are connected to an acoustic modem arranged to transmit the anchor condition data to the vessel and/or another involved vessel.
- The acoustic modem may be arranged to transmit the anchor condition data to the vessel and/or another involved vessel via a wireless transmission path. However, it may be preferred that the acoustic modem is arranged to transmit the anchor condition data to the vessel via the interconnection line.
- In connection with the latter preferred option, the invention may, alternatively, be defined more in general as a system for data transfer between two objects which are mechanically interconnected by an interconnection line, each object including an acoustic modem which is arranged to transmit and/or receive data via the interconnection line. Such an interconnection line could be operated -as defined in the preamble- for interconnecting a vessel and an anchor, or e.g. an electricity cable hanging between (and thus interconnecting) pylons, or a cable of a (cable) lift. In all such configurations data could be exchanged using acoustic modems on either cable end and using the cable as a transmission medium for those acoustic modems. Thus, it is proposed here to use cable which has another primary purpose than data transmission as an acoustic communication channel (waveguide), through which structure borne (guided) elastic waves can be transmitted. The cable can be used as an acoustic transmission line (wave guide). By using appropriate acoustic sources at specific frequencies, acoustic modes can be excited in the cable which looses only a small portion of the acoustic energy, or no acoustic energy at all, to the surrounding sand and water.
- Hereinafter the invention will be elucidated by means of an exemplary embodiment, shown in
Figure 1 . -
Figure 1 shows a mooring system for a vessel 1, including (in twofold) a mooring anchor 2 and an interconnection (mooring)line 3 for connecting the anchor 2 to the vessel 1. The anchor 2 comprises amonitoring unit 4 which is arranged for monitoring the anchor's condition, e.g. the anchor's position, its orientation angle, depth under the seafloor etc., detected by suitable detectors (not shown) and reported possibly as a function of time. The anchor condition data are outputted to an acoustic modem 5 which is arranged to transmit the anchor condition data to the vessel 1 via theinterconnection line 3. At the side of the vessel 1 anacoustic modem 6 is arranged to receive the anchor condition data and to pass it to amonitoring system 7. - An additional
acoustic modem 8 may be arranged to transmit the anchor condition data to another involved vessel, e.g. an inspection and maintenance vessel 9, via a wireless transmission path, constituted by the (sea)water between themodem 8 and the vessel 9 The data sent to the vessel 9 may be identified -to prevent confusion about its origin- by means of a specific anchor or modem identifier added to the anchor condition data. The identifier and the anchor condition data are received at the side of the vessel 9 by anacoustic modem 10, which passes it to a processing system (not shown) in vessel 9.
