Marlink launches Sealink Multi-LEO, a unified managed service integrating Starlink and Eutelsat OneWeb to provide high-throughput, low-latency maritime connectivity. This hybrid solution simplifies fleet-wide data management with a single subscription, enhancing network resilience and operational efficiency for global shipping routes.
OSLO and PARIS | March 3, 2026 – Marlink, the global leader in secure managed services for business-critical digital solutions, has announced the launch of Sealink Multi-LEO. This new hybrid connectivity service integrates high-throughput, low-latency Low Earth Orbit (LEO) networks into a single, fleet-wide managed service, significantly enhancing availability and resilience for shipowners and operators.
Overcoming Complexity with Unified Connectivity
As the maritime industry increasingly adopts LEO satellite technology, managing multiple providers has often led to operational and commercial fragmentation. Sealink Multi-LEO solves this by providing access to Starlink and Eutelsat OneWeb, with more networks to be added as they become available, under a single service model and commercial framework.
By delivering a single data allowance across multiple LEO solutions through one monthly subscription, Marlink eliminates the technical complexity of managing parallel satellite services.
Key Operational Benefits
The Sealink Multi-LEO service is designed to support the rigorous demands of modern maritime digitalization, offering:
- Enhanced Availability: By utilizing multiple constellations, the service mitigates geofencing constraints and ensures service continuity, even in areas of geopolitical risk.
- Increased Redundancy: The combination of multiple LEO networks provides a robust failsafe, reinforced by Marlink Cyber’s unified security solutions.
- Network Orchestration: The service is carrier-agnostic, dynamically selecting the best network based on real-time performance, coverage, and availability.
- Predictable Investment: Operators benefit from a flexible commercial model that allows for high-speed internet without the uncertainty of fluctuating costs across different providers.
Tailored for Fleet-Wide Performance
Marlink offers scalable data packages ranging from 500 gigabytes to 10 terabytes. For fleet operators, the service can be deployed on individual vessels or configured with pooling models, allowing data allowances to be shared across an entire fleet. This ensures that connectivity consumption aligns perfectly with specific operational profiles.
“Demand for LEO connectivity continues to grow as shipowners look for higher performance and greater predictability at sea,” said Tore Morten Olsen, President Maritime at Marlink. “With Sealink Multi-LEO, we are bringing together leading LEO networks into a single, fully managed service model that simplifies operations while delivering the performance and resilience our customers expect.”
The “Possibility Platform” Integration
The new service is delivered via Marlink’s Possibility Platform, which provides centralized visibility and policy control. This enables seamless orchestration across connectivity, cyber security, cloud, and IT services, ensuring that LEO services are operationally consistent and secure.
