Propulsion Systems

Propeller performance is the key for efficient conversion of generated power into thrust force. We provide all the necessary tools to analyze propulsion system performance, from the propeller in isolation to sub-systems and full system performance for complete power management.  Predict propeller performance, cavitation and erosion using our hydrodynamics simulation capabilities, then analyze noise and dynamic response, vibration and structural integrity with our powerful 3D tools.

The marine industry is pushing hard for the highest efficiency in ship propulsion. As stringent emission regulations remain high on the agenda, energy savings of a few percent significantly improve compliance and operational viability. While reduced fuel consumption and operating costs are the main requirements, noise, vibration and cavitation need to be minimized as well.

Achieving an optimal propulsion system early in the design phase ensures the vessel meets contract requirements while improving sea-going capacity and reducing vessel fuel consumption. Our solutions create a propeller digital twin early in the design phase, giving understanding of propulsion effects at full scale. From propeller in isolation to sub-systems to full system performance, design an optimal, innovative propulsion system that meets contractual and regulatory obligations at a lower cost.

Use our propulsion system solutions to:

  • Predict propeller performance, including the effects of cavitation and erosion.
  • Optimize propeller designs for required operational efficiency.
  • Simulate self-propulsion and analyze design-critical operating conditions.
  • Improve existing fleet efficiency via energy saving devices and other refit options.
  • Minimize vibro-acoustics, ensuring reduced environmental footprint and structural integrity.
  • Provide accurate inputs to load calculations and system simulations.
