Tinjauan Teknis Instalasi Jalur Pipa Buried pada Sistem Distribusi Bahan Bakar di Terminal Pelabuhan Jamrud Surabaya
Abstract - The addition of new pipelines to the fuel oil distribution pipeline system is carried out from Mirah Terminal to the jetty at Jamrud Terminal. The pipe is laid underground with a depth of +1.5 m from the ground surface to the bottom of the pipe. Buried pipe shall be evaluated to ensure that the soil provides adequate containment to limit pipe movement, to prevent unacceptable stress and/or strain levels in the pipe, and to prevent failure of the earth support. A technical review was carried out on the buried pipeline installation design with uncased conditions, especially on the stress aspect. Stress analysis is carried out with reference to the provisions of API RP 1102 and ASME B31.4. From the results of the stress analysis, that the magnitude of the stress due to internal load is 2243,357 psi, earth load is 281,330 psi, live load is 1174.766 psi (circumferential stress) and 971.715 psi (longitudinal stress), sustain load is 2330.4 psi, occasional seismic 690 ,4, occasional seismic + wheel load 6933 psi. The results of the analysis show that the stresses that occur in the pipeline are within safe limits according to API RP 1102 and ASME B31.4.
