Propeller Design

Are you looking for an optimized propeller that matches your type of ship and sailing profile? Using advanced CFD simulations, the hydrodynamic performance of your ship is analyzed to create a propeller design that not only improves efficiency but also meets your specific requirements. Essential aspects such as fluid dynamics, material selection, and the complex interaction with other propulsion components, such as nozzles and rudders, are taken into account.

Nozzle Design

Are you in need of a nozzle with the correct profile, such as 19A, 37, or HR, tailored to your appendages, hull form, and sailing profile? The validated methodology for nozzle designs involves the use of various CFD simulations. This includes detailed analyses to understand the dynamics with other components in the aft. Additionally, various placement methods are explored in the stern to achieve optimal integration.

Rudder Design

Are you in search of an optimized ship rudder design seamlessly integrating with your other appendages, tailored to the unique shape and sailing profile of your vessel? Or are you faced with the challenging choice between two or more rudder models and could benefit from additional insights for your existing or new ship? In either scenario, CFD simulations offer valuable insights, enabling you to make a well-informed decision.

Energy Saving Devices

In addition to optimizing propellers, rudders, and nozzles, the potential efficiency improvements of Energy Saving Devices (ESDs) can also be explored, designed, and delivered. Examples of these include a Pre-Duct, Pre-Swirl Stator (PSS), Propeller Boss Cap Fin (PBCF), and Twisted Rudder and Rudder Bulb.

3D Scan

If you don’t have drawings of your current vessel but still want to explore the possibility of an optimized design for the propeller, nozzle, rudder, or Energy Saving Devices, a 3D scan provides a solution. Through this scan, along with precise measurements, the hydrodynamics of both the fore and aft ship, including existing appendages, are mapped out. Based on this information, an optimal design of your propulsion component can be determined even without drawings, seamlessly aligning with your vessel type, hull, bow, other appendages, sailing profile, unique characteristics, and your specific desires and needs as a customer.

In Practice

For a fully electric-powered ferry, two CFD-optimized ship propellers have been designed and delivered. Through CFD simulations, the required propulsion power has also been determined, providing the customer with valuable insight when choosing the appropriate capacity for the battery pack. The optimized propeller design is specifically tailored to the desired speed and sailing route of this ferry.

For the ferry shown in this image, two CFD-optimized ship propellers have been designed and delivered.

Optimized Propeller Design

In optimizing propeller design tailored to your propulsion needs, the focus is on crucial parameters such as diameter, pitch, number of blades, propeller speed, material, and shape. These parameters significantly impact thrust, efficiency, durability, hydrodynamics, noise production, vibration levels, and cavitation of the ship’s propeller.

For an accurate analysis of the hydrodynamic performance of your fore and aft ship, validated CFD simulations are utilized. This involves simulating your ship’s movement in a digital towing tank. The insights gained from these tests lead to a balanced propeller design precisely tuned to the characteristics of your ship and sailing profile.

The goal in determining the optimal propeller design depends on what is technically feasible as well as your specific desires and needs as a customer. The aim is to minimize resistance, maximize fuel efficiency, and ensure robustness and navigational safety in various conditions, such as shallow waters and Arctic environments. At all times, efforts are made to limit vibrations, noise production, and cavitation.

In addition to improved propeller design, the delivery of the ship’s propeller is also possible. Visit our page on the CFD-optimized ship propeller for more information.

Optimized Nozzle Design

When selecting the appropriate nozzle design, various aspects are examined beyond just the ideal placement and interaction with other propulsion components. The CFD analysis also integrates the shape of the bow, providing profound insight into the water flows and resistance of both the fore and aft ship. This comprehensive evaluation enables the selection and design of the most suitable nozzle profile.

The primary objective is to find a nozzle profile that contributes to various improvements, such as increased thrust, enhanced fuel efficiency, improved maneuverability, reduced cavitation, minimal resistance, and a focused effort to reduce onboard noise and vibration levels. Technical feasibility is, of course, taken into account, considering specific desires and needs.

Furthermore, there is the option to customize the nozzle profile, such as 19A, 37, or HR, for potentially even higher efficiency improvements for specific ship types and propulsion systems.

In addition to improved nozzle design, the delivery of the nozzle is also possible. Visit our page on the CFD-optimized propeller nozzle for more information.

Optimized Rudder Design

An optimized design of the ship’s rudder, achieved through extensive CFD analysis, involves careful choices for the appropriate rudder profile, optimized suspension, and precise positioning of the rudder stock. All adjustments are custom-tailored to you, taking into account the hydrodynamics of your other components, such as the ship’s propeller and nozzle. This is done in accordance with the unique shape of your vessel, including the bow shape, and its specific sailing profile.

The primary objective is to select a rudder profile that enables various improvements and aligns with your specific desires and needs, while considering technical feasibility. This includes enhancing maneuverability, facilitating efficient steering, minimizing resistance, reducing vibrations and noise production, and promoting improved stability.

In addition to improved rudder design, the delivery of the ship rudder is also possible. Visit our page on the CFD-optimized ship rudder for more information.
