Abstract

Perangkat lunak In-service Piping Inspection yang dirancang dalam tugas akhir ini dimaksudkan untuk memenuhi ketentuan API 570 dan API 574. Perangkat lunak ini memiliki fungsi-fungsi penting yang meliputi penyimpanan dan analisis pembacaan ketebalan aktual, perhitungan corrosion rate jangka pendek dan jangka panjang, retirement date, MAWP, dan interval inspeksi. Selain itu, perangkat lunak ini juga mampu menandai area dengan corrosion rate tinggi, piping circuit yang terlambat untuk diperiksa, serta perpipaan yang mendekati nilai minimum ketebalan yang dibutuhkan. Penelitian ini berhasil menghasilkan perangkat lunak In-service Piping Inspection yang telah diuji melalui 52 skenario. Fungsi-fungsi yang dimaksud dalam API 570 sub-section 7.9.4 Computer Record (Edisi ke-4 - 2016) terbukti telah terimplementasi dengan baik. Pembuktian ini dapat dilihat melalui fitur-fitur yang disajikan dalam halaman "thickness," "cml thickness," "cml trend," dan "piping trend" untuk memenuhi ketentuan a) sub-section 7.9.4. Selain itu, fitur-fitur pada halaman "piping assets," "thickness," dan "cml thickness" digunakan untuk memenuhi persyaratan b) sub-section 7.9.4. Untuk memenuhi persyaratan c) sub-section 7.9.4, fitur-fitur pada halaman "thickness" dan "cml thickness," serta fitur sortir pada MAWP, min required thickness, dan corrosion rate telah berhasil diterapkan. Dengan demikian, perangkat lunak In-service Piping Inspection yang dirancang dalam penelitian ini memiliki potensi untuk membantu dalam inspeksi pipa yang sedang beroperasi. Perangkat lunak ini dapat secara efektif menyimpan, menganalisis, dan memberikan informasi penting terkait ketebalan aktual, corrosion rate, retirement date, MAWP, dan interval inspeksi. Dengan adanya penandaan area yang membutuhkan perhatian khusus, perangkat lunak ini juga dapat membantu dalam pengambilan keputusan yang tepat terkait perawatan dan pemeliharaan sistem perpipaan.

The software "In-Service Piping Inspection" developed in this final project is designed to comply with API 570 and API 574 requirements. It encompasses essential functions such as storing and analyzing actual thickness readings, calculating short and long-term corrosion rates, retirement dates, MAWP, and inspection intervals. Moreover, the software is capable of identifying areas with high corrosion rates, late-inspection piping circuits, and pipelines approaching the minimum required thickness. The research successfully resulted in the In-Service Piping Inspection software, which underwent testing through 52 scenarios. The functions specified in API 570 sub-section 7.9.4 Computer Record (4th Edition - 2016) were well-implemented, evident through features presented on the "thickness," "cml thickness," "cml trend," and "piping trend" pages to meet requirement a) of sub-section 7.9.4. Additionally, features on the "piping assets," "thickness," and "cml thickness" pages were used to fulfill requirement b) of sub-section 7.9.4. For requirement c) of sub-section 7.9.4, features on the "thickness" and "cml thickness" pages, along with sorting features on MAWP, min required thickness, and corrosion rate, were successfully applied. Consequently, this in-service piping inspection software developed in the study has the potential to assist in inspecting operational piping effectively. It can efficiently store, analyze, and provide crucial information regarding actual thickness, corrosion rate, retirement date, MAWP, and inspection intervals. The software's ability to mark areas requiring special attention also aids in making informed decisions regarding pipeline system maintenance and upkeep.
