OMS Group and EGS Australia have completed a cable route survey offshore Western Australia using an uncrewed surface vessel, marking a meaningful shift in how subsea infrastructure surveys are executed in the region. The project deployed EGS Australia’s Fremantle 01, a purpose built uncrewed survey vessel designed specifically for high precision geophysical operations on the continental shelf. Operating without onboard crew, the platform conducted cable route survey activities traditionally performed by larger manned vessels. From a technical standpoint, this deployment reflects more than a simple equipment substitution. It demonstrates that autonomous marine platforms are now capable of meeting the strict data quality requirements demanded by modern subsea cable development, particularly in energy and telecommunications corridors where route accuracy directly affects long term asset reliability.
High Precision Geophysical Survey Performance With Reduced Offshore Risk Exposure
Cable route surveys require detailed seabed mapping, sub bottom profiling, and geophysical characterization to identify hazards such as rocky outcrops, sediment instability, or anthropogenic debris. These datasets form the foundation for route engineering and cable burial strategy. Using the Fremantle class USV allowed continuous offshore operations without placing survey personnel in direct exposure to marine risks. From a Health, Safety and Environment perspective, this is one of the most significant advantages of uncrewed deployment. Removing offshore crew reduces exposure to vessel motion injuries, weather related incidents, and fatigue related risk. In my view, this is where autonomous vessels deliver immediate and measurable value. Safety improvements are not theoretical. They directly affect insurance costs, regulatory compliance, and long term contractor performance metrics.
Extended Range and Endurance Improve Survey Efficiency and Carbon Performance
The Fremantle class USV is designed for endurance. With a range of approximately 2000 nautical miles and the ability to remain at sea for up to 15 days between services, the platform supports extended offshore campaigns without the logistics footprint of a conventional survey vessel. This endurance profile enables three key improvements:
- Lower fuel consumption compared to crewed offshore vessels.
- Reduced port calls and transit cycles.
- Minimized marine disturbance during operations.
As subsea cable development accelerates across Asia Pacific, operators are under increasing pressure to demonstrate lower emission project delivery. Deploying autonomous survey platforms is becoming a practical way to align infrastructure development with environmental performance targets. This project signals that USVs are transitioning from experimental deployments to commercially validated survey assets.
Strategic Implications for the Global Subsea Cable Industry
Autonomous systems are unlikely to replace conventional survey vessels entirely. Instead, they are emerging as complementary assets that extend operational flexibility. USVs are particularly well suited for shallow water corridors, nearshore sections, and long endurance reconnaissance work. The broader implication is scalability. If fleets of regionally positioned USVs can be mobilized quickly, survey timelines compress and project staging becomes more agile. That matters in a subsea cable market that supports offshore wind, interconnectors, data centers, and international telecommunications links. Both OMS Group and EGS Australia have signaled that autonomous platforms will play a growing role in their subsea project ecosystem. Based on current industry momentum, this appears less like experimentation and more like strategic positioning.
About OMS Group
OMS Group is an international subsea cable installation and maintenance contractor serving telecommunications and offshore energy markets. The company operates a fleet of specialized cable laying vessels and supports projects across Asia Pacific and beyond. With increasing demand for submarine fiber optic and power cable infrastructure, OMS continues to expand its operational capabilities through technology adoption.
About EGS Australia
EGS Australia is part of the broader EGS Group, a marine survey and geoscience organization active since the 1990s. EGS provides geophysical, geotechnical, and positioning services globally, supporting offshore energy, telecommunications, and infrastructure sectors. The Fremantle class USV platform reflects the company’s move toward autonomous survey solutions tailored for continental shelf operations. As offshore infrastructure demand grows, companies that combine traditional marine expertise with scalable autonomous technology are likely to define the next phase of subsea development.
