Hull Form
Optimize the hull form of your existing or new ship using a validated, multidisciplinary CFD methodology. This comprehensive approach focuses not only on the bow shape but also examines the hydrodynamic performance of the stern, including propulsion components such as propellers, nozzles, and rudders. This enhanced hull form design is based on performance data obtained through monitoring or provided by you as the shipping company or shipowner.
Trim
Optimizing the trim is a crucial aspect of achieving more energy-efficient sailing. This involves adjusting the position of your ship in the water to optimize the center of buoyancy. This directly impacts water resistance and, consequently, fuel consumption. An advanced approach to this is the use of Computational Fluid Dynamics (CFD) simulations. Through this analysis, detailed insights are gained into the water flows around your ship, allowing various trim configurations to be effectively explored.
Self-Propulsion
Validated numerical self-propulsion tests can be conducted to simulate and enhance the hydrodynamics of your vessel. These CFD simulations, also known as self-propulsion tests, accurately replicate the sailing behavior of your vessel with its designed propeller. Thanks to extensive experience in CFD-optimized ship propellers and the validation of results in practice, the expected performance in operational sailing situations can be predicted with high accuracy.
Bollard Pull
With CFD-based bollard pull analyses, the maximum pulling force can be accurately calculated. This is particularly relevant for tugboats that are often utilized to assist large vessels in docking or navigating through narrow passages. In such situations, the tugboat’s maximum pulling force is crucial for executing effective maneuvers and maintaining control over the towed vessel.
Propulsion
In addition to optimizing hull shape and trim, CFD offers the opportunity to enhance the hydrodynamic performance of individual propulsion components, such as ship propellers, nozzles, and rudders. Whether you are specifically interested in a new, optimized propeller or want to explore various rudder and/or nozzle profiles, CFD simulations enable you to determine the most optimal design tailored to your vessel and sailing profile.
Express Analysis
The International Convention for the Prevention of Pollution from Ships (MARPOL) mandates regulations to gradually reduce the carbon intensity of the global shipping fleet. Examples of these regulations include the Ship Energy Efficiency Management Plan (SEEMP), the Energy Efficiency Design Index (EEDI), the Energy Efficiency Existing Ship Index (EEXI), and the Carbon Intensity Indicator (CII).
The Express Analysis not only focuses on simulating and optimizing the hydrodynamics of your ship but also explores a range of energy-saving techniques above the waterline. This ensures compliance with current and future maritime environmental laws and regulations.
In Practice
With passion and dedication, shipowners, as well as small, medium, and large shipping companies, are supported in making their current and future ship designs more sustainable and efficient.
