Abstract

Struktur anjungan minyak dan gas lepas pantai memiliki masa operasi dalam setiap desainnya. Saat masa operasi ini berakhir, maka setiap struktur anjungan akan memasuki fase pascaproduksi, yakni pembongkaran (decommissioning) instalasi struktur anjungan. Terdapat beberapa alternatif DRE (Dismantlement, Repair dan Engineering) pada pembongkaran anjungan minyak dan gas lepas pantai diantaranya total removal, partial removal dan leave in place. Dalam memilih alternatif DRE pada pembongkaran perlu diperhatikan kriteria yang harus dipertimbangkan sebelum melaksanakan pembongkaran anjungan antara lain lingkungan, biaya, dan alih fungsi serta keamanan dalam pembongkaran anjungan lepas pantai. Oleh karena itu, penting dilakukan analisa pengambilan keputusan yang akan dijadikan sebagai pertimbangan sebelum melaksanakan pembongkaran anjungan. Pada tugas akhir ini dilakukan analisa pengambilan keputusan dengan teknik kuantitatif dan kualitatif untuk pembongkaran anjungan minyak dan gas lepas pantai dengan metode AHP dan SAW. Dari hasil analisis didapatkan keputusan alternatif DRE pada pombongkaran fixed platform dengan metode AHP dan SAW adalah total removal dengan masing-masing bobot adalah 0,60 dan 0,93. =============================================================================== The structure of offshore platform has a lifetime of operation in each of its designs. When this operation end, the structure of the platform will enter the post-production phase, that is decommissioning the installation of the platform structure. There are several dismantlement, repair and engineering (DRE) alternative on decommissioning of offshore platfrom including total removal, partial removal and leave in place. In choosing DRE alternative on decommissioning, it is necessary to consider the criteria that must be considered before carrying out the decommissioning of the platform, such as environment, cost, conversion and sefety. Therefore, it is important to make decision analysis that will be taken into consideration before undertaking the decommissioning of offshore platform. In this bachelor thesis, a decision making analysis with quantitative and qualitative techniques is used to select DRE alternatives on offshore platform decommissioning with AHP and SAW methods. From the analysis result obtained the DRE alternative decision on fixed platform decommissioning with AHP and SAW method is total removal with each weight is 0.60 and 0.93.
