Individual Stiffness of Mooring Line Solution

STEP 0: Pre-Calculation Summary
Formula Used
Individual Stiffness of a Mooring Line = Axial Tension or Load on a Mooring Line/Elongation in the Mooring Line
kn = Tn/Δln
This formula uses 3 Variables
Variables Used
Individual Stiffness of a Mooring Line - Individual Stiffness of a Mooring Line [force/length] is based on the differential changes tensions in mooring lines.
Axial Tension or Load on a Mooring Line - (Measured in Newton) - Axial Tension or Load on a Mooring Line [force] is the maximum load that a mooring line should be subjected to in operational service, calculated from the standard environmental criteria.
Elongation in the Mooring Line - (Measured in Meter) - Elongation in the Mooring Line [length]. A mooring is any permanent structure to which a vessel may be secured.
STEP 1: Convert Input(s) to Base Unit
Axial Tension or Load on a Mooring Line: 160 Kilonewton --> 160000 Newton (Check conversion here)
Elongation in the Mooring Line: 5 Meter --> 5 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
kn = Tn/Δln --> 160000/5
Evaluating ... ...
kn = 32000
STEP 3: Convert Result to Output's Unit
32000 --> No Conversion Required
FINAL ANSWER
32000 <-- Individual Stiffness of a Mooring Line
(Calculation completed in 00.020 seconds)

Undamped Natural Period of Vessel
Go Undamped Natural Period of a Vessel = 2*pi*(sqrt(Virtual Mass of the Ship/Effective Spring Constant))
Effective Spring Constant given Undamped Natural Period
Go Effective Spring Constant = ((2*pi)^2*Virtual Mass of the Ship)/Undamped Natural Period of a Vessel^2
Virtual Mass of Vessel given Undamped Natural Period
Go Virtual Mass of the Ship = (Undamped Natural Period of a Vessel^2*Effective Spring Constant)/(2*pi)^2

Go Individual Stiffness of a Mooring Line = Axial Tension or Load on a Mooring Line/Elongation in the Mooring Line
Elongation in Mooring Line given Individual Stiffness of Mooring Line
Go Mooring Line Elongation = Axial Tension or Load on a Mooring Line/Individual Stiffness of a Mooring Line
Axial Tension or Load given Individual Stiffness of Mooring Line
Go Axial Tension or Load on a Mooring Line = Mooring Line Elongation*Individual Stiffness of a Mooring Line
Elongation in Mooring Line given Percent Elongation in Mooring Line
Go Elongation in the Mooring Line = Length of Mooring Line*(Percent elongation in a Mooring Line/100)
Length of Mooring Line given percent Elongation in Mooring Line
Go Length of Mooring Line = Elongation in the Mooring Line/(Percent elongation in a Mooring Line/100)
Percent Elongation in Mooring Line
Go Percent elongation in a Mooring Line = 100*(Elongation in the Mooring Line/Length of Mooring Line)
Mass of Vessel due to Inertial Effects of Water entrained with Vessel
Go Mass of Vessel due to Inertial Effects = Virtual Mass of the Ship-Mass of a Vessel
Mass of Vessel given Virtual Mass of Vessel
Go Mass of a Vessel = Virtual Mass of the Ship-Mass of Vessel due to Inertial Effects
Virtual Mass of Vessel
Go Virtual Mass of the Ship = Mass of a Vessel+Mass of Vessel due to Inertial Effects

Individual Stiffness of Mooring Line Formula

Individual Stiffness of a Mooring Line = Axial Tension or Load on a Mooring Line/Elongation in the Mooring Line

What are Ocean Moorings?

A Mooring in oceanography is a collection of devices connected to a wire and anchored on the sea floor. It is the Eulerian way of measuring ocean currents, since a mooring is stationary at a fixed location. In contrast to that, the Lagrangian way measures the motion of an oceanographic drifter, the Lagrangian drifter
