Abstract

Wahana benam berpenggerak diesel elektrik memiliki kelemahan utama akan terbatasnya sumber tenaga untuk penggeraknya. Seringkali wahana benam diesel elektrik muncul ke permukaan untuk mengisi baterai menggunakan diesel generator. Oleh karena itu, dibutuhkan sumber tenaga yang memungkinkan wahana benam bertahan lebih lama di dalam air tanpa harus muncul ke permukaan untuk mengisi baterai. Sistem tersebut bernama Air Independent Propulsion (AIP), yang dapat menambah endurance wahana benam diesel elektrik menjadi lebih lama di dalam air. Pada tugas akhir ini dipilih sistem AIP dengan jenis fuel cell, karena memiliki efisiensi yang tinggi, proses generasi energi tenang, dan proses kontrol sangat baik. Sistem ini memanfaatkan reaksi hidrogen dan oksigen untuk menghasilkan arus listrik dengan produk sampingan air dan energi panas. PEM Siemens fuel cell 120 kW dipilih untuk dipasangkan pada wahana benam objek. Perhitungan yang dilakukan meliputi perhitungan arus, perhitungan konsumsi oksigen dan hidrogen, perhitungan produksi air, dan perhitungan penambahan endurance kapal selam. Dari hasil perhitungan diketahui arus dari fuel cell, konsumsi hidrogen dan oksigen dalam satuan kilogram per jam, jumlah produksi air dalam liter per jam dan penambahan endurance di dalam air. ======================================================================================================= Diesel-electric submersible vehicle has a major disadvantage on limited source of energy for propulsion. Diesel-electric submersible vehicle going to surface to charge the battery by using diesel generator. Therefore, we need a source of energy that allows the submersible vehicle to last longer in the water without surfacing to charge the battery. The system is called Air Independent Propulsion (AIP), which can increase endurance diesel-electric submersible vehicle to be longer in the water. This final project selected AIP system with this type of fuel cell, because it has high efficiency, quiet energy generation process, and process control is very good. The system utilizes the reaction of hydrogen and oxygen to produce electrical current, water, and heat energy. A Siemens PEM fuel cell 120 kW have to be fitted on the submersible vehicle object. Calculations are including the calculation of the fuel cell current, oxygen and hydrogen consumption, calculation of water production, and the endurance for submersible vehicle. From the calculation results can be seen the current of the fuel cell, hydrogen and oxygen consumption in units of kg per hour, the production amount of water in liters per hour and increased endurance in the water.
