Design Analysis of Impressed Current Cathodic Protection for Fuel Distribution Pipeline System at Eastern Fleet Command Naval Base

Abstract

Fuel is main requirement of KRI (Indonesian Warship) in activities of basic training, warfare alert and operation at sea. To pock of fuel demand from KRI at Eastern Fleet Command Base, it needs a new pipeline of fuel distribution system. The pipeline system used for maximum lifetime must be protected from corrosion. Basically, there are five methods of corrosion control such as change to a more suitable material, modification to the environment, use of protective coating, design modification to the system or component, and the application of cathodic or anodic protection. Cathodic protection for pipeline available in two kinds, namely Sacrifice Anode and Impressed Current Cathodic Protection (ICCP). This paper makes analysis from design of Impressed Current Cathodic Protection and total current requirement in the method. This paper showed both experimental from speciment test and theoritical calculation. The result showed that design of Impressed Current Cathodic Protection on fuel distribution system requires voltage 33,759 V(DC), protection current 6,6035 A(DC) by theoritical calculation and 6,544 A(DC) from pipeline specimen test, with 0,25 mpy for corrosion rate. Tranformer Rectifier design needs requirements 45 V with 10 A for current. This research result can be made as literature and standardization for Indonesia Navy in designing the Impressed Current Cathodic Protection for fuel distribution pipeline system.
