The electrical system is very important thing on a ship, where the tool that functions as power to meet the electricity needs on the ship is a generator. In some cases, generator planning does not pay attention to technical and economic factors that have an impact on operations cost. The technical factor will be adjusted to the standard and regulations of the classification board, while the economic factor will be planning an efficient electrical installation and power installation system. The results obtained from this paper show the operational needs of the ship based on the condition when harbour, sailing, loading and unloading, and emergency during the day with total intermittent load of 110,6 KW and total continuous load of 130,6 KW while the operational needs of the ship at night with total intermittent load is 98,2 KW and total continuous load is 181,5 KW. Then it was found that the largest operational power requirement of the ship in an emergency at night was 38,5 KW and the largest power was in the condition of the ship at night of 102,5 KW. Then we get 3 generators with 2 sets of 60 KW power capacity and 1 set of 45 KW.
