In response to this problem, OXZO engaged Tesacom, a specialist in deploying integrated communication networks in remote and inhospitable environments, to develop a solution that used Inmarsat’s global satellite network to deliver constant connectivity and reliable transmission of data from the floating platforms to the company’s monitoring centre.
Viviana Fonseca, CEO at Tesacom, explains how the company worked in a consultative approach with Inmarsat to develop a satellite connectivity solution that could overcome OXZO’s challenges: “We recognised that the communications issues caused by the remote and challenging location of off-shore sea cages meant that satellite was the only viable connectivity option. We needed a robust communications solution that could withstand the irregular movements of the sea and continue to transmit data to OXZO’s control room. We opted to replace the existing VSAT technology with a Hughes 9502 machine-to-machine integrated antenna terminal using Inmarsat’s Broadband Global Area Network (BGAN) service.
“We chose the BGAN solution because it is ideal for supervisory control and data acquisition solutions that require point-to-point connections. Working with Inmarsat’s L-band service, rather than the much narrower Ku-band frequency of the VSAT solution, gave us much greater flexibility and ensured constant connectivity to the platforms, regardless of where they are situated.”
The BGAN terminals are more than capable of operating in this environment, with an IP66 rating that protects the technology from dust and water. Using Inmarsat’s global satellite network, the terminals provide data connection speeds of 448 kbps upload and 464 kbps download and offer 99.9% availability. This ensures that OXZO can operate the oxygen distribution system remotely, regardless of the conditions.
