Case 1.1: KVLCC2 Deep water, forces & moments

- KVLCC2 hull shape
- Fixed in surge, sway, roll and yaw. Upright condition (Ø=0). The experimental results are obtained free to trim and sink
- Calm water
- Deep water. The results will be compared to experiments carried out at a water depth to draught ratio 13.4.
- L
_{PP}= 6.893 m (scale 46.426) - V
_{model}=1.1702 m/s, Fn = 0.142 (corresponding to full scale 15.5 knots) - g = 9.81 [m/s
^{2}], ρ=1000 [kg/m^{3}]; ν=1.27×10^{-6}[m^{2}/s] - Propeller present. The propeller should work at the propeller point so that there is self propulsion at V
_{model}=1.1702 m/s, Fn = 0.142 (corresponding to full scale 15.5 knots). During the model tests, the propeller was working at 9.9 rev/s. - Rudder present, but at zero rudder angle (exactly zero).

- You can only submit case 1.1.2 when you delivered case 1.1.1
- You can only deliver case 1.1.2 package 2 when you deliver case 1.1.2 package 1.
- You can only deliver case 1.1.2 package 3 when you deliver case 1.1.2 package 2.

- The N-moment (moment around the z-axis) should be supplied w.r.t. the midship.
- Only the hydrodynamic forces are to be supplied: the inertial forces are not to be included.
- Forces and moments are to be given non-dimensional:

The yellow fields in the excel sheet should be filled in. The excel sheet should be send to the organizing committee per email address “simman2019host@gmail.com”.

Table below gives an example of the data that we would be getting for the KVLCC2 for case 1.1.1 and 1.1.2. Submitters should generate an excel sheet in the format of the Table below. The submitter has to type the calculated X’, Y’ and N’ ..
