Mini VSAT technologies will allow real-time seismic surveys, higher redundancy and seamless communications from offshore vessels.


Increasing bandwidth capacity and falling rates will allow real-time seismic surveys and video applications. New higher throughput satellites will provide quicker information transmissions from offshore vessels, says service provider Harris CapRock Communications. Its president, Tracey Haslam, stated very small aperture terminal (VSAT) technologies was enhancing to enhance bandwidth in various frequency bands. Much more satellite capacity is coming more than the subsequent 5 years that can allow vessel operators to stream reside information in true time and use far more applications.

The Growth of Mini VSAT Technology

She expects the subsequent generation of satellites will allow seismic vessel operators to give much better survey information solutions. “Imagine what we are going to be capable of do with all the bandwidth,” she mentioned. “We could get to a point exactly where real-time seismic surveys could possibly be accessible. We are able to accelerate information transmissions, and there will probably be a cost point exactly where real-time seismic information transmissions operate.”


Within the meantime, Harris CapRock has constructed redundancy into its communications options. It delivers C-band, Ku-band and Ka-band VSAT solutions to offshore vessel operators. This can be now backed up with line-of-sight radio and mobile telephone 3G and long-term evolution (LTE) 4G networks. It introduced OnePath wireless radio for higher throughput and enhanced redundancy for offshore vessels. It enables safe, localized wireless information and voice networks with connections as much as 160km, according to the height of your antenna. It may provide throughputs of as much as 400 Mbps operating modes for point-to-point and point-to-multipoint applications.

The Reach of Mini VSAT

Haslam recommended a mixture of LTE and OnePath Radio installed on a drilling rig, floating production facility, accommodation, building vessel or pipelayer could offer speedy communications for surrounding OSVs. “We would then have an location of low expense mobile communications.” She continued, “Connectivity must be seamless and integrated. We are able to use LTE, and all satellite bands to make up a complete network using a module to handle least-cost routing and OnePath Radio for redundancy. Harris Caprock gained a contract extension from Oceaneering International for VSAT solutions on its fleet of multipurpose assistance vessels. This incorporates initiating solutions onboard Oceaneering’s new multiservice assistance vessel Ocean Evolution.

Mini VSAT connectivity is by way of C-band and Ku-band from satellite operators for instance SES and Intelsat. “When switching for the backup network, there need to be no packet loss and no dropped telephone calls, even though there’s a satellite or teleport failure,” stated Spytek. “There ought to be no degradation because the method can use a second satellite. This way, we’ve got two offered networks for accurate redundancy.”
