    In this thesis use of hybrid energy storage systems (HESS) in commercial ships's auxiliary power system (not for propulsion) was investigated in terms of emission reduction during maneuvering and strait passages. For the HESS proposed in this thesis, the appropriate battery group has been determined for a 10-year service period, taking into account the characteristics of the battery types to be used as well as the load characteristics of the ship. In the first part of the study a hypothetical study was carried out on a real commercial tanker vessel sailing in Turkey's inland waters and frequently using the Çanakkale and Istanbul straits. First of all, the actual fuel consumption data of the ship was analyzed and the emissions and fuel consumption during local maneuvers and channel navigation were evaluated on a 2-year basis. Afterwards, the same parameters were then evaluated for the case of having a hybrid energy storage system for the auxiliary power system on board. These analyses show that the use of hybrid auxiliary systems on commercial vessels leads to a reduction in local emissions. In the second part of the study, using the annual maritime traffic data of the Istanbul and Çanakkale straits, which have the highest maritime traffic in Turkey, the potential emission reductions in the straits were calculated if ships transiting these straits used a hybrid energy system instead of keeping two generators running to ensure the operational continuity of their auxiliary systems. In this context; The components of hybrid energy systems used on-board ships and their decisive criteria have been checked. Battery types which are used in Battery-Hybrid systems have been checked. Engineering and operational challenges such as power fluctuations which must be compensated, have been investigated.
