What is the Fender Energy Absorption & How does it work?

Fender systems are critical for safely absorbing the kinetic energy of a vessel as it comes to rest against a berth. The amount of energy that must be dissipated depends primarily on the vessel’s effective berthing mass and its approach speed.

The basic energy balance assumes that the kinetic energy of the vessel is transferred to the fender during the short impact period. This energy can be expressed by the classic kinetic‑energy equation, which forms the foundation for most fender‑design calculations.

Designers use the calculated energy to select fender types, sizes, and materials that will deform or compress enough to absorb the impact without causing damage to the vessel or the quay.

E = 0.5 times m times v^{2}
E = energy absorbed (kJ), m = effective berthing mass (tonnes), v = berthing velocity (m/s)

Frequently Asked Questions
What is the formula used for calculating kinetic energy in this calculator?
The kinetic energy is calculated using the formula KE = 0.5 * m * v^2, where m is the mass of the vessel and v is its velocity.
How does the fender system absorb energy from a vessel?
The fender system absorbs energy by dissipating the kinetic energy of the vessel during the impact period as it comes to rest against a berth.
What factors are considered in this calculator for energy absorption?
This calculator considers the effective berthing mass of the vessel and its approach speed to determine the amount of energy that must be dissipated.
Can this calculator be used for different types of vessels?
Yes, this calculator can be adapted for various types of vessels by adjusting the parameters such as mass and speed according to the specific vessel’s characteristics.
What is the importance of fender systems in maritime navigation?
Fender systems are crucial for safely absorbing the kinetic energy of a vessel, preventing damage to both the ship and the berth during berthing operations.
