Abstract

Banyak anjungan lepas pantai di Indonesia, terutama di wilayah Natuna, yang telah beroperasi selama lebih dari 20 tahun dan akan segera memasuki fase pasca-operasi. Salah satu opsi decommissioning yang diusulkan yakni reutilization atau penggunaan kembali offshore platform ini sebagai fasilitas pembangkit energi baru terbarukan (EBT). Pemanfaatan kembali anjungan lepas pantai tidak hanya mendukung program Indonesia untuk transisi menuju energi bersih dan memingkatkan komitmen terhadap dekarbonisasi, tetapi juga mengurangi dampak lingkungan dan meningkatkan efisiensi biaya decommissioning. Dalam penelitian ini, terdapat tiga skenario konfigurasi energi baru terbarukan sebagai pembangkit listrik yang akan dikembangkan yaitu Pembangkit Listrik Tenaga Surya (PLTS), Pembangkit Listrik Tenaga Bayu (PLTB), dan kombinasi PLTS dan PLTB (hibrida). Pemilihan pembangkit EBT menggunakan dua metode yakni dengan optimasi pada perangkat lunak HOMER Pro dan pendekatan matematis yang dikombinasikan dengan Multi-Criteria Decision Making (MCDM), yaitu CRITIC dan MOORA. Hasil analisis pada kedua metode menunjukkan bahwa Pembangkit Listrik Tenaga Surya (PLTS) adalah alternatif EBT yang paling menguntungkan. PLTS dengan kapasitas produksi listrik 288,954 kWh/tahun mampu menghemat 69,384 m³ bahan bakar dengan luas dek 882.6 m², menawarkan biaya produksi listrik (LCOE) $0.02/ kWh, Internal Rate of Return (IRR) 17%, Return on Investment (ROI) 23%, dan penghematan sebesar $17,831.68/tahun. Selain itu, PLTS dapat mengurangi emisi CO2 sebesar 152 ton/tahun. Dapat disimpulkan bahwa PLTS menjadi pilihan EBT yang paling menguntungkan untuk pemanfaatan kembali anjungan lepas pantai pasca-operasi di Natuna. Penelitian ini menawarkan pendekatan alternatif dalam memanfaatkan infrastruktur lepas pantai untuk produksi energi listrik terbarukan, berkontribusi terhadap tujuan energi bersih nasional, dan menunjukkan pendekatan yang progresif dalam menghadapi transisi energi.

============================================================
A considerable number of offshore platforms in Indonesia, particularly those situated in the Natuna region, have been operational for over two decades and are now approaching the post-operation phase. One of the proposed decommissioning options is the utilization of these offshore platforms as new renewable energy (NRE) generation facilities. This approach offers a dual benefit to Indonesia, supporting the country's transition to clean energy and increased commitment to decarbonization, while simultaneously reducing environmental impact and improving decommissioning cost efficiency. In this study, three scenarios of post-production platforms were reutilized as renewable energy generation namely Solar Power Plants, Wind Power Plant, and a combination of them (hybrid). The Selection of the NRE using two methods: HOMER Pro software and a mathematical approach combined with the Multi-Criteria Decision Making (MCDM) CRITIC-MOORA method. The results of the analysis, derived from both methods, indicate that the solar power plant represents the most profitable NRE alternative. A solar power plant with an electricity production capacity of 288,954 kWh/year has the potential to save 69.384 m³ of fuel with a deck area of 882.6 m², thereby offering a cost of electricity production (LCOE) of $0.02/kWh. The capital cost of energy (COE) is $0.02 per kilowatt-hour, with an internal rate of return (IRR) of 17% and a return on investment (ROI) of 23%. Furthermore, savings of $17,831.68 per year are anticipated. Furthermore, the implementation of solar PV technology has the potential to reduce CO₂ emissions by 152 tonnes per year. Consequently, solar PV represents a highly favorable renewable energy option for post-operational offshore platforms. This research presents an alternative approach to utilizing offshore infrastructure for renewable electricity production, contributes to national clean energy goals, and demonstrates a progressive approach to the energy transition.
