An Offshore Power System Engineered From Wave, Solar, and Storage Technologies
Defining the System
Ocean energy provides a stable baseline, with solar and battery storage adding flexibility and system redundancy.
Mocean’s system is a standalone offshore renewable power ‘platform’designed to deliver energy and communications at the point of need, for subsea equipment and remote offshore operations. The system is designed with configuration flexibility to match specific equipment demand. By combining ocean energy, solar generation, and battery storage, the system delivers operational capability, supporting offshore assets with reliable power, communications, and reduced intervention requirements.
Blue Star 10 is Mocean’s commercially available offshore renewable power system, delivering 10 kW of wave energy generation with 2 kW of solar.
The system is based closely on previously built and tested hardware, incorporating learnings from multiple offshore deployments, including the Renewables for Subsea Power (RSP) program. Blue Star 10 represents a baseline configuration that can be deployed today for a range of subsea and remote offshore applications.
Blue Star 20 is a higher-capacity offshore renewable power system currently in development, designed around the requirements of power-intensive subsea applications, including all-electric CCS.
The system increases wave energy and solar capacity while reusing proven subsystems and design principles from Blue Star 10, ensuring predictable performance, robustness, and offshore survivability.
Mocean’s product platform is designed to scale across applications and power requirements.
Using a proven design process, software optimisation, and qualified subsystems, Mocean can develop additional system variants that build directly on deployed architectures. An example configuration developed for an offshore platform application is shown here.
Core Technologies at Work
Geometry-Driven Energy Conversion
The system’s geometry is a core innovation, optimised to convert wave motion into electrical energy efficiently across a broad wave spectrum.
Sloped wave channels increase response across conditions, while passive weathervaning allows the platform to naturally align with dominant wave direction, improving performance without active control.

Hybrid Energy Production
Wave and solar generation are combined with onboard energy storage to deliver a stable power supply across varying conditions.
The complementary nature of ocean energy and solar reduces intermittency and improves availability compared to single-source systems.

Subsea Connection and Mooring
The system is moored using a compliant arrangement and connects to subsea equipment via a dynamic umbilical.
Energy generation is achieved through relative motion between hulls, rather than reaction against the seabed or moorings, making the system effectively depth-agnostic and suitable for deepwater deployment.

Passive Survivability
The platform is designed to survive extreme sea states using passive response rather than active survival modes.
It can submerge and pass through large waves, analogous to a surfer diving through the surf, reducing structural loads while maintaining system integrity. In many conditions, power generation continues even during severe seas.

Performance and Design Software
Mocean uses proprietary software tools validated against real-world offshore testing.
These tools assess performance at global locations and support optimisation of system configurations for specific applications and operating requirements.

Qualified, Robust System Design
The system is engineered with few moving parts and relies on qualified, off-the-shelf subsystems, with targeted innovation applied where it delivers the greatest impact, such as geometry and generator design.
Development follows recognised engineering standards and structured technology qualification processes, informed by operator engagement and internationally recognised assessment frameworks, including IEA-OES performance metrics.

Reliability
by Design
Layered Redundancy
Multiple generation sources combined with storage capability increase system redundancy and reduce the likelihood of power and communication drop-outs.
Pilot Programs
We favour simplicity and off-the-shelf subsystems to boost reliability, introducing targeted innovation where necessary for critical functionality and maximum impact.
Offshore Survivability
Robust, passive strategies allow the system to avoid extremes, “ducking” steep waves or remotely de-tuning high-stress dynamics, while continuing to supply power.
Predictable Performance
Unique geometry maximises energy capture across a wide range of sea states. Simple architecture supports stable operation and delivers controlled, predictable performance.
