N2 - Dynamic positioning system is a system that maintains floating offshore structures and ships their position on a certain coordinate that the have been prearranged. The dynamic positioning system uses thrusters, which require additional power. As a consequence the fuel consumption is increasing. In the installation of a dynamic positioning system, the configuration of a split bus is usually applied. As of lately, there are a lot of concern in changing to a closed bus configuration because theoretically the system will have high efficiency and low emission. An analysis is performed to observe the condition of unbalance voltage of dynamic positioning system of a ship by modelling in a laboratory scale system. Several scenarios and variations are used to see the condition of the unbalance. The system modelling results in 220V∠0°, 218V∠-113.7°, 218V∠123.18° for scenario 1 variation 1, 220V∠0°, 220V∠-120°, 218∠120° for scenario 2 variation 1, and lastly 219∠0°, 220∠-120°, 220∠120° for scenario 3 variation 1. The highest unbalance condition happens on scenario 1 variation 3 with a PVUR of 0.78%.
