Dynamic Positioning - Failure Simulation Tool

 

This interactive part of the website is about simulating failure cases of a Dynamic Positioning

System. As an example, calculations are performed for a given set of environmental loads,

on a given vessel with a class 2 DP System.

 

 

 

 

 

Brief specification of the DP system

 

In the table below a brief specification of the DP system is given. The first sketch is a schematic

representation of the thruster layout and the second sketch is used for static analysis.

Thruster capacity

 

Having determined the required amount of thrust and

power, the DP configuration was optimized to meet these

requirements.

 

This results in 2500 kW thrusters in locations 1, 2 and 3

and 3500 kW thrusters in locations 4, 5 and 6.

 

With all thrusters operational the situation looks as follows.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

DP Failure Simulation Tool

 

The application to the right makes it

possible to plot a DP Rosette and

Utilization plot for the discussed

DP system. What makes it special,

is the fact that you can:

 

1. Switch thrusters on/off

2. Change thruster power

 

So that you can simulate

 

1. Thruster configurations

2. Different Failure Cases

 

           Have a try!

 

Hint:

 

    Compare your results

  with the fully operational

    situation (look above)
