Result Interpretation

Ports Navigation Channel Depth Determination (Under-Keel Clearance) calculator computes Required Navigation Channel Depth in m using the defined engineering formula and the input values provided. Required Navigation Channel Depth is expressed in m. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

Vessel Draft = 10.2
Tide Height Above Chart Datum = 1.8
Squat Correction = 0.35
Safety Margin = 0.6

Expected Result:

Required Navigation Channel Depth = 12.95

Engineering Interpretation:

Under the given input conditions, the calculated result is: Required Navigation Channel Depth = 12.95 m.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Formula / Method

required navigation channel depth = vessel draft + tide height above chart datum + squat correction + safety margin
