It rigorously calculates all the forces on the vessel, viz.
1. Calm Water Resistance: It is calculated using the established Holtrop and Mennen formula
2. Wind resistance: Based on Wind Height and Shape coefficients from ABS MODU rules, and corrected for wind direction.
3. Wave Resistance: From DNV Rules for Marine Operations, and corrected for forward vessel speed using Faltinsen, 1990
4. Propeller resistance and Hawser resistance: From US Navy Towing Manual
Very useful in Marine Operations. It can be used to accurately predict the bollard pull to tow a vessel. The tug can be accordingly selected.
