The energy sector is transforming, driven by digitalisation, decentralisation, and an ever-growing demand for sustainability. In this evolving landscape, hybrid, blended networks and robust cyber security frameworks are emerging as the backbone of modern operations. For energy companies, these solutions enable more efficient operations, support remote crews, and safeguard critical infrastructure against increasingly sophisticated cyber threats.

The Power of Hybrid Networks

Hybrid networks—where terrestrial, satellite, and other connectivity solutions are seamlessly integrated—offer a unique edge for energy companies operating in remote and offshore locations. Unlike traditional connectivity solutions, hybrid networks dynamically blend multiple technologies, ensuring consistent performance and resilience.

For instance, offshore rigs often sit far beyond the reach of fibre or traditional terrestrial networks. Here, hybrid systems use satellite links to deliver baseline connectivity while terrestrial options—like LTE or private 5G—are utilised closer to shore. When one pathway is congested, unavailable, or disrupted, traffic is rerouted automatically to the most efficient alternative.

This "always-on" network isn’t just about maintaining business continuity; it’s about enabling advanced operations. Predictive maintenance tools, powered by IoT sensors, can relay real-time data back to onshore command centres. Cloud-based applications for asset management can become accessible anywhere, improving productivity and reducing downtime. Crucially, hybrid networks allow for scalability, enabling energy companies to adapt to growing demands or new projects without overhauling their infrastructure.

However, one of the main benefits of hybrid networks lies in their ability to create a bridge between seemingly disconnected worlds. Energy companies can unify their global operations by having interconnected remote assets, head offices, and supply chains, fostering collaboration and innovation.

Cyber Security: A Growing Imperative

As energy operations become more reliant on connected systems, the sector faces an alarming increase in cyber threats. From ransomware attacks targeting corporate data to cyber criminals probing critical infrastructure, the repercussions of a cyber incident extend beyond financial losses; they can jeopardise worker safety, disrupt supply chains, and compromise operational stability.

The industry’s unique connectivity challenges across oceans, deserts, and remote regions increase the number of potential entry points for attacks. Cyber criminals can exploit vulnerabilities in satellite links, IoT devices, and unprotected endpoints to infiltrate networks.

Managed services like those offered by Marlink take a proactive approach to cyber security. End-to-end visibility and real-time threat monitoring ensure that unusual activity is detected early, while automated responses mitigate potential damage. A layered defence strategy, encompassing encryption, firewalls, and next-generation intrusion detection, is essential for safeguarding critical data flows.

The focus must also extend to educating employees. Cyber security is not just an IT responsibility; it’s a company-wide commitment. Crew members working remotely should be equipped with training and tools to identify phishing attempts, secure their devices, and contribute to overall cyber resilience.

Crew Welfare: Staying Connected to Home

While operational efficiency and security take centre stage, it’s essential not to overlook the human side of connectivity. For the thousands of crew members working offshore or in remote locations, connectivity is more than a convenience—it’s a lifeline to home.

Energy workers often spend weeks, if not months, away from their families, and access to reliable, high-speed internet can significantly improve their well-being. Whether video calling family, streaming entertainment, or staying updated on world news, a hybrid network ensures these connections remain uninterrupted.

Studies consistently show that companies prioritising employee well-being see higher retention rates, increased productivity, and stronger morale. Happy, connected crew members are more likely to stay with an organisation, reducing the costs and disruption of high turnover.

Marlink’s managed hybrid networks are designed to ensure both effective operations and crew welfare. By prioritising low-latency links and dedicated bandwidth for crew welfare applications, energy companies can support their workforce while creating a secure operational environment.

A Blueprint for the Future

Today's networking and cyber security decisions will shape the industry’s future. Managed hybrid networks offer a resilient, scalable, and cost-effective solution to the sector’s most pressing challenges, ensuring energy companies can operate efficiently in even the most remote environments.

Alongside this, robust cyber security measures must remain a top priority. The energy sector's threats are real and growing. A holistic approach - encompassing technology, training, and strategy - will be essential to mitigate risks and safeguard operations.

Finally, while digitalising operations, it is key to ensure that crew welfare is seen as a fundamental component of the design. By addressing the human dimension of digitalisation, energy companies can build stronger, more resilient teams ready to tackle the challenges ahead.

In a world where the stakes are higher than ever, managed hybrid networks and cutting-edge cyber security solutions are more than tools—they are enablers of progress, safety, and sustainability for the energy sector. The future belongs to those who embrace them.
