| Summary: | Oil is one of the mostly used energy source. One of the key factor that can affect oil production process is the distribution process of the oil itself. Distribution process of oil did by using pipeline which is commonly made from steel. One of the problem in using steel is the corrosion. Corrosion can affect pipeline integrity so that corrosion control in pipeline is needed. Some of corrosion control methods that can be applied is coating application, inhibitor and cathodic protection. Designing process of cathodic protection with sacrificial anode method for onshore and offshore oil pipeline has been done in this final project. Designing process in this final project is based on ISO 15589 part 1, for the onshore pipeline, and ISO 15589 part 2 for the offshore pipeline. Case study in this final project is based on the oil pipeline of crude terminal in Lawe- Lawe, East Kalimantan, Indonesia. The result of the design in this final project, for 30 years of the design life, shows that, for the offshore pipeline with 42 inches diameter and 12 kilometres length, 137 anodes is needed for the protection with the weight of each anode is 144,5 kg. For the onshore pipeline with 42 inches diameter and 7 kilometres length, 123 anodes is needed for the protection with the weight of each anode is 27,2 kg. There are some important parameters that has been analyzed in this final project. Some of the parameters are pipe size, coating breakdown factor, and electrolyte resistivity. Also in this final project has been developed a calculation sheet that can be helping in cathodic protection design calculation. |
