Abstract

Cadangan minyak dan gas di Indonesia tergolong masih sangat besar. Pada Maret 2019 lalu, Menteri Energi dan Sumber Daya Mineral, Ignasius Jonan meresmikan tambahan pasokan gas lapangan Terang Sirasun Batur (TSB) milik Kangean Energy sehingga diperlukan suatu Offshore supply vessel untuk memasok kebutuhan lapangan pengeboran tersebut. Pada penelitian ini, peneliti melakukan inovasi terhadap kapal dengan menambahkan fuel cell sebagai sumber tenaga penggerak berbahan bakar hidrogen. Bahan bakar yang digunakan pada fuel cell ini adalah gas hidrogen. Penambahan hidrogen sebagai bahan bakar dapat mengurangi biaya operasional tepatnya pada biaya bahan bakar. Selain itu, gas hidrogen juga terbukti hanya menghasilkan air sebagai emisi buangnya. Analisis teknis yang dibahas yaitu penentuan ukuran utama kapal melalui sketsa awal, koefisien bentuk kapal melalui pendekatan, hambatan & propulsi kapal melalui holtrop, berat & titik berat, trim, freeboard, dan stabilitas kapal menggunakan metode pendekatan dan software maxsurf. Ukuran utama kapal yang ialah Lpp = 43.2 m, B = 11.3 m, H = 4 m, dan T = 2.8 m. Analisis ekonomis dilakukan untuk menghitung biaya pembangunan kapal, biaya operasional, dan juga kelayakan investasinya. Dari segi ekonomis, investasi dalam pembuatan kapal ini sangat layak dijalankan dengan nilai BEP Rp. 113.494.789.274, NPV Rp. 28.137.119.108, PI 1.51907, IRR 18.25 %, Payback Period 5,42 tahun dengan harga sewa Rp. 293.269.231 per trip untuk jenis sewa voyage charter dan untuk jenis sewa time charter meiliki nilai BEP Rp 151.954.718.010, NPV Rp. 32.532.731.322, PI 1.60016, IRR 19,49 %, Payback Period 5,26 tahun dan harga sewa Rp 1.439.685.315 per bulan. ============================================================================================== Oil and gas reserves in Indonesia are still classified as large. In March 2019, the Minister of Energy and Mineral Resources, Ignasius Jonan, inaugurated the additional supply of Kangean Energy's Terang Sirasun Batur’s (TSB) gas field, owned by Kangean Energy. With the addition of these drilling blocks, ships are needed to fulfill the logistics needs of the ship and the crew. In this study, the researchers innovated the ships by adding fuel cells as a source of propulsionto drive ships. The fuel used in this fuel cell is hydrogen gas. Adding hydrogen as fuel can reduce fuel costs. In addition, hydrogen gas is also proven to only produce water as its output. The technical analysis discussed was to determining the main size of the ship by sketch, the coefficient of the ship’s shape using formula, resistance & propulsion of the ship using Holtrop method, weight & center of gravity, trim, freeboard, and the stability of the ship using formula and maxsurf software. The main dimensions of the ship are Lpp = 43.2 m, B = 11.3 m, H = 4 m, and T = 2.8 m. Economic analysis is carried out to calculate the cost of the ship’s construction, operational costs, and also the feasibility of investment. In terms of economics, investment in shipbuilding is very feasible to run with a BEP value of Rp. 113.494.789.274, NPV Rp 28.137.119.108, PI 1.51907,, IRR 18.25 %, Payback Period 5,42 years with a rental price of Rp. 293.269.231 per string for the type of voyage charter rental, and for the type of time charter rental having a BEP value of Rp. 151.954.718.010, NPV Rp. 32.532.731.322, PI 1.60016, IRR 19,49 %, Payback Period 5,26 years with a rental price of Rp 1.439.685.315 per month.
