Holtrop and Mennen

Implementation Notes

  1. Holtrop and Mennen power prediction implemented in accordance with the methods described [1, 2], supported by general references [3, 4].
  2. Wageningen B-Series Propeller implemented in accordance with methods described in [4], with validation from [3, 5].  Polynomial values taken from [6].
  3. Gawn Propeller Series implemented as described in [7] using Polynomial values taken from [6].
  4. Taylor and Hughes Air resistance methods taken from description in [4].
  5. ITTC method of Air resistance taken from [3], modified to account for relative wind speed.
  6. Air Drag coefficient values as suggested by [4].
  7. Hull Transverse area for air drag calculated from the calculation section with maximum area above the waterline.
  8. Burrell Cavitation limits implemented as described in [4, 3].
  9. Service Margin implemented as described in the AVEVA Marine Initial Design Hydrostatics Documentation.
  10. Entrance Angle calculated taking the breadth of the waterplane, 30% back from the forward point to the point of maximum breadth or beginning of parallel waterline.
