Abstract
The addition of dynamic positioning system on offshore auxiliary vessels leads to the installation of a large powered bow thruster. Unpredictable fieldwork conditions lead to uncertain loading. Changes in electrical system configuration and load shedding scheme are just a few of the many ways to maintain electrical system stability. This method is done in order to balance the generator mechanical power generated with the load needs. The configuration changes has been made and the result was that the closed bus of 2 generator thruster and 2 diesel generator configurations have excellent stability that can reach stable conditions with 110% loading on each bow thruster. While Rhe closed bus configuration of 1 thruster generator and 2 diesel generator provides an opportunity to rest 1 generator thruster to save generator usage. However, the stability of this configuration can be improved by conducting a load shedding scheme.
