Established physics
Potential-flow hydrodynamics, Project Chrono multibody dynamics and FEA, MoorDyn moorings, PTO models and control interfaces — integrated for coupled time-domain simulation.
Simocean
Simulation for complex marine systems.
Simulation software, coupled modelling, and engineering support for marine energy, offshore systems, and ocean technology.
SEA-Stack: open-source simulation software.
SEA-Stack is an open-source C++ time-domain platform for coupled marine and offshore system simulation. Simocean develops SEA-Stack with NLR and UW–Madison.
It couples hydrodynamics, structures, moorings, PTO and control in one time-domain model — for interactive runs, design campaigns and higher-fidelity follow-up, without re-translating the model at each step.
Built on engineering foundations
SEA-Stack brings together established engineering methods and specialist simulation software in an open, inspectable framework.
Designed for technical workflows
Interactive visualisation when it helps; reproducible headless runs, YAML-defined cases, parameter campaigns and engineering outputs when it matters.
Open and verifiable
SEA-Stack is MIT-licensed, with source code, packaged releases and verification, regression and comparison reports published alongside releases.
Developed with NLR and UW–Madison with funding from the U.S. Department of Energy.
Services
Simocean works with industry, academia, and government on simulation software, coupled modelling, and technical assessment of ocean and marine systems.
Simulation software: build, extend, integrate
Custom C++/Chrono tooling, SEA-Stack workflows, and coupling to existing solvers or hardware — including hardware-in-the-loop interfaces.
Coupled-system modelling and design exploration
Time-domain models of floating and moored systems; interactive runs and headless sea-state campaigns to explore performance and loads before deployment.
Independent model and design review
Independent assessment of models, assumptions, and system designs for teams who need a second technical opinion.

About Simocean
Simocean builds and applies engineering simulation for ocean and marine systems — especially cases where hydrodynamics, multibody dynamics, moorings, power take-off and control must be solved together.
We work with device developers, offshore and marine operations teams, labs, and research groups who need credible time-domain models before hardware or tank testing.
Simocean develops SEA-Stack with NLR and UW–Madison — an open-source platform for this class of coupled simulation.

Time to Put a Damper on Things…
When a floating body oscillates in water, it radiates waves. Radiation damping is fundamental to how wave energy converters capture power.
