Propulsion Dynamics Inc. was founded in 2002 by Torben Munk, a naval architect and ship technical director with more than 50 years hydrodynamic experience in the industry. He has also served as an expert witness in the Danish courts involving matters related to guaranteed speed and power specifications in ship design and sea trial performance.
There are 3 areas of performance analysis that make our services unique and robust:
Speed through water calculations
In CASPER, the speed through water is calculated from propeller revolutions, power delivered to the propeller and propeller design; whereas onboard speed logs and GPS are unable to accurately measure speed through water.
Heavy weather corrections
Full hydrodynamic correction for all displacements and sea states BF0-BF7. This means that we generate Speed-Power tables for all drafts, and all-weather scenarios. Most contemporary performance monitoring systems are unable to correct for heavy weather encountered by the ship in operation.
Theoretical and empirical algorithms for the influence of hull and propeller roughness and fouling on speed losses and increased in bunker costs at present and in the future. From this, we can separate the performance losses, between, engine, hull and propeller.
The innovative analysis is called the CASPER© (Computerized Analysis of Ship Performance). The benefits of this new method of analysis were radical and dramatic for the first ship owners who signed up for the CASPER program in 2003. Ships enrolled in the CASPER program significantly improved fuel efficiency within the first year.
Propulsion Dynamics helped foster a global awareness of the importance of hull and propeller resistance as a Key Performance Indicator in fuel conservation and emission reduction programs. The term 'Hull and Propeller Performance Monitoring" is one of the key measures to reduce fuel consumption and reduce emissions in the (IMO) Ship Energy Efficiency Management Plan as well as Interanko's TEMP.
