What is NavCad?

Reliable and reliable performance forecast

Simulation of Hydrodynamic and Propulsion Systems

Quickly analyze vessel speed and power performance. NavCad provides marine designers with the tools they need to optimize the optimal selection of suitable components of the propulsion system.

Unsurpassed in hydrodynamic design and ship analysis

NavCad is the leading simulation tool for propulsion and hydrodynamic systems, providing powerful systems engineering calculations for marine vehicle performance. NavCad was developed based on the physics-based performance balance of the Vessel-Propellant-Drive system model and is known for its reliable and reliable prediction.

NavCad contains an extensive library of forecasting methods for hulls, thrusters and all necessary parts, making it the most efficient and comprehensive platform for analysis, from early stage design to after-delivery test evaluation. Used for any type of monohull or catamaran vehicle, from large displacement vessels to fast planing vessels and submersibles, it supports a variety of drive and drive options.

Whether the focus is vessel, propellant, drive - or the system - the NavCad remains the gold standard for performance prediction for more than 30 years.

Advanced Analytics

NavCad's advanced features allow you to go beyond speed forecasting. Quickly analyze a mooring trailer design or determine speed time using an acceleration analysis. Use existing assets such as model tests, sea tests, or CFD calculations to correlate and align forecasts – offering the highest fidelity at the lowest cost. Use supplemental analysis to verify hydroacoustics, sinking and compensation, drag reduction, dynamic planning stability, and more.

NavCad Premium

NavCad Premium Edition offers an advanced user toolset for optimized design, lifecycle evaluation, and workflow efficiency. NavCad Premium is a vital tool for evaluating vessel-drive system design space or for the vessel hull shape component. Its Distributed Volume Analytical Method (ADVM) complements hull shape analysis with a unique and unique numerical calculation of wave production resistance. The script for batch calculations and the use of NavCad Premium as a calculation server make it the ideal coupled solver for optimization and design studies integrated with CAD and CFD. The service profile operating modes module provides NavCad Premium users with an understanding of system performance metrics across the operational scenario and ship lifecycle, including power KPIs and GHG emissions.
