Namun sepengetahuan penulis belum ada penelitian mengenai pembuatan aplikasi desain sistem proteksi katodik arus paksa anjungan lepas pantai. Penelitian ini bertujuan untuk membuat aplikasi desain sistem proteksi katodik arus paksa pada anjungan lepas pantai.Aplikasi dibuat dengan mengaplikasikan beberapa perhitungan dari beberapa literatur dengan pendekatan empiris. Dari hasil output aplikasi tersebut kemudian dibandingkan dengan nilai atenuasimya untuk mengkonfirmasi kecukupan arus. Kemudian analisa keekonomisan dapat dilakukan dengan memvariasikan parameter umur layan, tipe cat yang digunakan, serta luas permukaan dicat. Desain struktur dan kondisi parameter lingkungan anjungan lepas pantai “V” di PT. XYZ digunakan sebagai objek penelitian. Output yang dihas...

This method is done by connecting the steel structure to be protected with other metals that have lower electronegativity or by flowing electric current through an external anode. Generally cathodic protection designs in modern times are based on recommended practices or international standards, empirical approaches, and guidance from previous practical experience. The objective of this study is to design impressed current cathodic protection ICCP system for offshore platforms. The study begins by gathering information or parameters that will be used as input variables in calculations, such as environmental data, structure and anode dimensions, cable resistance, electrical equipment data, and others. In this study, offshore platform in East Kalimantan was used as an object of the research. Structural design of the "V" offshore platform at PT. XYZ is use as research object. The results of this research include DC current requirements, the number of anodes, DC voltages & currents, and power capacity of transformers / rectifiers. It was found that at the service life of 20 years, 4 anodes were needed, while from attenuation it was found that the number of anodes was sufficient to cover all parts of the structure.
