Verification

One of the leading European research laboratories, Marintek/SINTEF Ocean, has conducted towing tank tests of different FlowBow designs to verify the resistance reduction achieved with the FlowBow concept.​

10.0 knots (30m) - - - 15.0 knots (68m) - - - Froude number 0.30

10.7 knots (30m) - - - 16.0 knots (68m) - - - Froude number 0.32

11.3 knots (30m) - - - 17.0 knots (68m) - - - Froude number 0.34

12.0 knots (30m) - - - 18.0 knots (68m) - - - Froude number 0.36

Resistance full scale 68 meter – FlowBow only ​

(i.e. no FlowStern modification)

To further analyze the physics behind the FlowBow concept, and to support the towing tank tests, several CFD analyses have been conducted.

Showing the effect of waves hitting the flowbow

All data from Marintek/SINTEF Ocean confirms a significand reduction in propulsion resistance and vast a reduction in wave formation. Our “in house” test results shows god resemblance with Marintek/SINTEF Ocean test results.​
