Abstract

Floating Production Storage and Offloading (FPSO) merupakan salah satu platform lepas pantai terapung yang berperan untuk memproses dan menyimpan minyak dan gas sebelum didistribusi ke konsumen. Bagian penting dari FPSO yang dirancang untuk memastikan produk agar dapat diproses dan dikirim dengan aman adalah modular bagian atas. Saat ini, proyek Seawater Filtration Module tengah menghadapi tantangan keterlambatan yang berdampak pada biaya dan waktu penyelesaian. Dengan menggunakan studi kasus yang ada, penelitian ini menggunakan metode Critical Path Method (CPM) untuk mengidentifikasi jalur kritis dari keseluruhan jadwal proyek serta penggunaan Program Evaluation and Review Technique (PERT) untuk mengelola ketidakpastian waktu penyelesaian pada aktivitas kritis. Untuk mengevaluasi percepatan dengan mempertimbangkan biaya tambahan, digunakan metode Time-Cost Trade-Off (TCTO). Hasil penelitian menunjukkan bahwa proyek mengalami keterlambatan selama 51 hari dari jadwal awal yang menargetkan penyelesaian pada 31 Januari 2024. Sebanyak 11 aktivitas teridentifikasi sebagai jalur kritis yang menyebabkan keterlambatan tersebut. Untuk mengatasinya, dilakukan percepatan melalui penambahan tenaga kerja berdasarkan produktivitas masing-masing aktivitas. Hasil menunjukkan bahwa penambahan total 17 pekerja mampu mengurangi durasi aktivitas kritis dari 721 hari menjadi 670 hari. Analisis probabilitas menunjukkan bahwa peluang keberhasilan percepatan mencapai 82,64%. Sementara itu, perhitungan menunjukkan bahwa percepatan ini memerlukan biaya tambahan sebesar Rp30.913.709. Dengan demikian, percepatan melalui penambahan tenaga kerja dinilai efektif dan ekonomis dalam mengembalikan proyek ke jadwal semula.

Floating Production Storage and Offloading (FPSO) is an offshore floating platform designed to process and store oil. Floating Production Storage and Offloading (FPSO) is a type of floating offshore platform that functions to process and store oil and gas before being distributed to consumers. A critical component of the FPSO, designed to ensure the product can be safely processed and transported, is the topside module. Currently, the Seawater Filtration Module project is facing delay challenges that impact both project cost and completion time. Using the existing case study, this research applies the Critical Path Method (CPM) to identify the critical path within the overall project schedule, as well as the Program Evaluation and Review Technique (PERT) to manage uncertainties in the completion time of critical activities. To evaluate the acceleration strategy with consideration of additional costs, the Time-Cost Trade-Off (TCTO) method is employed. The research findings indicate that the project experienced a 51-day delay from the original schedule, which targeted completion by January 31, 2024. A total of 11 activities were identified as part of the critical path contributing to the delay. To address this issue, acceleration was carried out by adding labor based on the productivity of each activity. The results show that the addition of 17 workers successfully reduced the duration of critical activities from 721 days to 670 days. Probability analysis indicated a success rate of 82.64% for the acceleration effort. Meanwhile, the cost calculation showed that the acceleration required an additional expense of Rp 30,913,709. Therefore, accelerating the project through labor adjustment is considered effective and economical in restoring the project to its original schedule.
