Abstract
Anjungan lepas pantai minyak dan gas memiliki masa pakai antara 20-25 tahun. Saat anjungan telah mencapai batasan operasionalnya anjungan harus di bongkar (decommissioning). Ada berbagai kriteria untuk membongkar platform dan 4 metode decommissioning platform yaitu Complete Removal, Partial Removal, Toppling in Place, dan Leave in Place. Aktivitas decommissioning memiliki risiko kecelakaan yang tinggi dan berdampak kepada lingkungan maupun keselamatan manusia. Oleh karena itu, diperlukan analisa pemilihan metode decommissioning yang tepat dan analisis resiko pada proses decommissioning platform. Studi kasus penelitian ini adalah platform X milik PT. PHE ONWJ. Penelitian dilakukan analisis pemilihan metode decommissioning yang tepat menggunakan Analytic Hierarchy Process (AHP) serta analisis resiko pada proses decommissioning. Hasil dari penelitian didapatkan metode decommissioning yang tepat adalah Complete Removal yang ditentukan berdasarkan 4 kriteria yaitu Environmental, Cost, Legal, dan Security.Kegiatan yang paling beresiko pada saat proses decommissioning metode Complete Removal adalah tahap Platform Preparation.
