In an industry that prioritises efficiency, sustainability and the well-being of its crew, digitalisation is helping to completely transform Offshore Supply Vessel (OSV) operations. Thanks to smart solutions that enable informed decision-making and enhance crew connectivity, there has been a growing upswing in data usage among OSVs.

Resilient and secure communications

Inmarsat offers an exceptional solution to meet this rising demand for data; one that provides the combined strength of multiple networks to ensure offshore fleets remain seamlessly connected around the clock. Whether it’s a vessel in offshore fields, coastal areas or somewhere in between, our high-speed, global satellite connectivity helps ensure always-on, reliable communications from a single trusted supplier.

The power of four networks

Fleet Xpress is our flagship Ka-band solution, designed for seamless global mobility, with automated satellite and beam switching. Working in tandem, our FleetBroadband solution provides the added resilience of unlimited L-band backup.

This unique combination of our Global Xpress Ka-band and ELERA L-band networks helps ensure not only high-speed connectivity but also guaranteed performance. It also offers vessel owners the flexibility to switch between the two networks depending on the demands of their high-end offshore operations.

In addition, Inmarsat Fleet LTE brings 4G offshore networks to the integrated solution, offering triple-band mobile terrestrial connectivity with 99.9% network availability guaranteed. With OSV vessels spending around 40% of their time near the shore, we know how important it is to be able to switch to shore-based LTE networks and only rely on satellite services only when LTE is unavailable.

Finally, Fleet Reach, our coastal LTE service optimised for Fleet Xpress, ensures dedicated high-speed connectivity where network traffic is high, such as ports, by making a seamless transition from satellite to mobile terrestrial networks. It automatically connects the vessel to the high-speed LTE up to 10 nautical miles from the coast, while constantly scanning signal quality to ensure the best connectivity is maintained all the way into the port.

The combined strength of 4G offshore networks and high speed, low latency satellite communications, provides OSV fleets with truly mobile connectivity specifically for the North Sea and the Gulf of Mexico.
