Abstract

Pemerintah Indonesia memiliki target net zero emission (NZE) dengan pembatasan kenaikan suhu global 1.5-2oC hingga tahun 2050 dengan tujuan mengurangi dan mengendalikan emisi gas rumah kaca dengan metode Carbon Capture, Utilization, and Storage (CCUS). PLTU-Suralaya dapat menghasilkan 2.58 MT CO2/tahun. Berdasarkan data SKK Migas, Indonesia memiliki potensi penyimpanan 572.77 GT CO2 pada lapisan saline aquifer dan 4.85 GT CO2 pada depleted oil & gas reservoir untuk enhanced oil recovery (EOR). Penelitian ini berfokus pada transportasi dan injeksi di PHE Offshore North East Java (ONWJ) dengan kapasitas CO2 sebesar 7,220 MT pada lapisan saline aquifer dan 66 MT pada lapisan depleted oil & gas reservoir. Transportas dan injeksi di wilayah ini menggunakan kapal dinilai lebih ekonomis dan praktis daripada pipa. Hal ini didasari dengan sudah banyaknya pipa bawah laut yang tersebar serta saling tumpang tindih serta biaya yang lebih rendah apabila mendistribusikan CO2 kurang dari 400 km dengan kapasitas maksimal 2.5 MT CO2/tahun. Asean Development Bank (ADB) memberikan informasi bahwa Indonesia memiliki potensi untuk mentransportasikan serta menginjeksikan hingga 500-2,700 ton CO2/hari dalam fase demontrasi selama 10 tahun dan 2,700-30,000 ton CO2/hari dalam fase komersial selama 20 tahun. Tujuan penelitian ini untuk merancang kapal LCO2 Carrier yang mampu mentransportasikan CO2 dalam fase cair dan FSIU sebagai platform injeksi dalam fase gas. Penelitian ini menghasilkan dua desain kapal yang telah di analisa pada aspek technical dan economical. Pertama, ukuran utama Kapal LCO2 Carrier 7500 cbm LOA 130 m, LWL 127.5 m, LPP 122.6 m, breadth 22 m, height 9.5 m, draught 7 m, Cp 0.848, Cb 0.924, Cm 0.914, dan kecepatan 14 knot dengan ukuran utama tangki 39.7 x 12 x 12 m sebanyak dua unit. Total CAPEX untuk kapal LCO2 berkapasitas 7500 cbm mencapai IDR 370 miliar dengan belanja OPEX sebesar IDR 351 miliar pada tahun pertama operasi, yaitu 2028. OPEX ini kemudian diproyeksikan untuk proyek 25 tahun yang disesuaikan dengan tingkat inflasi sebesar 3,28%. Sementara itu, untuk Floating Storage and Injection Unit (FSIU) dengan kapasitas 7500 m3, total CAPEX diperkirakan mencapai IDR 1,1 triliun, dengan OPEX sebesar IDR 182 miliar pada tahun 2028.

Indonesian government has set a target for net zero emissions (NZE) with a global temperature rise limitation of 1.5-2°C by 2050, aiming to reduce and control greenhouse gas emissions through Carbon Capture, Utilization, and Storage (CCUS) methods. PLTU-Suralaya emits 2.58 million tons of CO2 per year. According to SKK Migas data, Indonesia has the potential to store 572.77 gigatons (GT) of CO2 in saline aquifer layers and 4.85 GT of CO2 in depleted oil & gas reservoirs for enhanced oil recovery (EOR). This research focuses on transportation and injection in the PHE Offshore North East Java (ONWJ), with a CO2 capacity of 7,220 MT in saline aquifer layers and 66 MT in depleted oil & gas reservoirs. Transportation and injection in this region using ships are considered more economical and practical than pipelines. This is based on the existing numerous overlapping underwater pipelines, as well as the lower cost of transporting CO2 over distances of less than 400 km, with a maximum capacity of 2.5 MT CO2 per year. The Asian Development Bank (ADB) provides information that Indonesia has the potential to transport and inject up to 500-2,700 tons of CO2 per day during the demonstration phase over 10 years, and 2,700-30,000 tons of CO2 per day during the commercial phase over 20 years. The objective of this study is to design a LCO2 Carrier vessel capable of transporting CO2 in liquid phase and an FSIU as an injection platform in the gas phase. This research produces two ship designs, which have been analyzed from both technical and economic aspects. The first design is for an LCO2 Carrier with a main dimentions of 7,500 cbm, LOA 130 m, LWL 127.5 m, LPP 122.6 m, breadth 22 m, height 9.5 m, draught 7 m, Cp 0.848, Cb 0.924, Cm 0.914, and a speed of 14 knots, with tank dimensions of 39.7 x 12 x 12 m, totaling two units.Total CAPEX for a 7,500 cbm LCO2 vessel reaches IDR 370 billion with OPEX spending of IDR 351 billion in the first year of operation, namely 2028. This OPEX is then projected for a 25-year project adjusted for an inflation rate of 3.28%. Meanwhile, for a Floating Storage and Injection Unit (FSIU) with a capacity of 7,500 m3, the total CAPEX is estimated to reach IDR 1.1 trillion, with OPEX of IDR 182 billion in 2028.
