WIFI MESH system/ LTE

Traditional wireless networks such as Point-to-Point (P2P) and Point-to-Multipoint (P2MP) could not support the constant moving of the different vessels. The network had to be able to accommodate both vessel movements and possible obstruction. N-centric provide the WIMAX solutions that supported the Oil and Gas, Dredging and Wind-farms sector. Alternatively, LTE solution is available

Field Coverage

We develop products that interconnect multiple vessels and rigs with in an ad-hoc self-forming mesh network. This network allows our clients to easily exchange live HD video, synchronize large files, enable M2M communication, etc. By connecting people and processes, we can maximize efficiency and create opportunities to make better decisions faster.


Extending the big VSAT pipe or fibre backhaul connection to all assets in the field can cut down on communication costs for all parties involved, while the bandwidth increases exponentially and latencies become negligible.

Norther OHVS

nCentric were recently requested to provide wireless access to the Norther OHVS. One of the reasons for doing this was that, while the OHVS was not connected to the grid but installed in the wind farm, was to have access to certain parameters coming from this OHVS towards onshore. These parameters can come from the SCADA systems, giving technical information about the OHVS or certain alarms, in case they would occur. These signals are then connected to the nCentric nodes, which themselves are wirelessly connected to the nCentric’s 5G LTE and Mesh network offshore. This principle makes it possible to monitor the information onshore. The nCentric’s solution combines multiple frequencies giving the Norther OHVS a fully redundant solution. In the event one system fails due to loss of line of sight, the other system will take over in a seamless manner. Practically the Norther OHVS will be online and monitored through the nCentric solution even though it is not yet connected to the grid.

Flansea Wave Pioneer

On April 23, 2013, the first Wave Pioneer was launched from the Port of Ostend. This monitoring generates a significant data stream, which is backhauled to the office using an nCentric wireless solution.

Challenges

Traditionally these type of solutions are provided by a VSAT provider. In this case VSAT isn’t the right solution, because the high installation cost and the expensive rate of data transmission. Furthermore the relatively small size of the buoy makes it difficult to install the VSAT hardware:

-The device must be able to withstand heavy pitch and roll.

-Wave Pioneer’s relatively small size makes it difficult to install a VSAT.

-Extremely high costs associated with the VSAT setup.

-Low power availability on the buoy.

-Failover is required, necessitating the installation of two independent wireless technologies.

-The high cost of VSAT transmission – Wave Pioneer transmits at least one gigabyte of data a day, which would be cost prohibitive using VSAT.

-Internet connection required for vessels in the proximity of the device.

Solution

The solution was to install nCentric’s ROBIN-R4 field coverage node on a lighthouse with an internet uplink, with ROBIN-R4 installed on the Wave Pioneer. Advantages of nCentric’s ROBIN-R4 include:

-ROBIN-R4’s antenna angles can cope with heavy pitch and roll.

-Installation costs are only a fraction of VSAT.

-Robin4 is much more compact, making installation easier and requiring a lot less power.

-There are no additional fees for transferring large amounts of data.

-Robin-R4’s high bandwidth ensures rapid data transfer.

-To further enhance communications, an additional access point was installed to create a WiFi hotspot around the buoy.
