Abstract
Kepulauan Riau (Kepri) merupakan salah satu provinsi kepulauan yang mempunyai sumber gas alam terbesar di Indonesia. Di salah satu pulau di provinsi ini, yaitu pulau Natuna akan dibangun Kilang Gas Alam Cair (Liquefied Natural Gas Plant atau LNG Plant) dengan perkiraan sumber gas alam terbesar di dunia. Gas alam ini akan didistribusikan ke seluruh konsumen baik domestik maupun internasional, mengingat kebutuhan gas yang semakin meningkat di era modern ini. Tugas Akhir ini diharapkan dapat memberikan solusi untuk menciptakan sebuah sarana distribusi gas alam cair sebagai penunjang kebutuhan gas di Indonesia, khususnya di provinsi Kepri sendiri. Payload dari kapal ini merupakan kebutuhan gas alam cair yang digunakan sebagai bahan bakar Pembangkit Listrik Tenaga Mesin Gas (PLTMG) yang ada di provinsi Kepri. Ukuran utama kapal ditentukan dengan penyesuaian jumlah dan ukuran tangki LNG yang digunakan berdasarkan kebutuhan LNG itu sendiri (billion British thermal units atau bBtu). Kapal yang dirancang menggunakan sistem permesinan berbahan bakar ganda atau dual fuel engine yang berbahan bakar LNG dan Marine Fuel (MDO). Setelah itu dilakukan perhitungan teknis berupa perhitungan berat, displacement, trim, freeboard, dan stabilitas. Ukuran utama yang didapatkan adalah Lpp = 96 m; B = 14 m; H = 6 m; T = 3,5 m. Tinggi freeboard minimum sebesar 947 mm, besarnya tonase kotor kapal adalah 3610,95 GT dan kondisi stabilitas Dual Fuel LNG Carrier memenuhi kriteria Intact Stability (IS) Code Reg. III/3.1. Analisis ekonomis yang dilakukan adalah memperhitungkan biaya pembangunan (investasi), biaya operasional, serta estimasi Break-Even Point (BEP). Biaya pembangunan Dual Fuel LNG Carrier ini sebesar Rp 162.302.693.118 dan estimasi BEP pada bulan ke-56 dengan estimasi pengambilan keuntungan bersih sebesar Rp 2.921.154.559.
=================================================================
Riau Islands is a province which has the biggest gas reservoir in Indonesia. A Gas Refinery (Liquefied Natural Gas Plant) is going to be built in one of the islands, named Natuna, which has the highest estimated natural gas reserve in the world. This gas will be distributed to domestic and international consumers, given the increasing gas needs in this modern era. This Final Project is intended to provide solution to create means of distribution of liquefied natural gas (LNG) to support gas needs in Indonesia, especially in Riau Islands itself. The payload of this ship is the need of LNG that is used as fuel by Gas Engine Power Plant (PLTMG) in Riau Islands. The ship’s main dimensions are determined by the adjustment of the amount of LNG tank(s) that are going to be used prior to the need of natural gas per day for each PLTMG (billion British thermal units/bBtu). The ship’s propulsion is designed to use dual fuel engine system that is fueled by LNG and Marine Fuel (MDO). Further calculations; (1) Technical calculation and analysis such as calculation of weight, displacement, trim, freeboard, and stability. The final ship’s main dimensions are Lpp = 96 m; B = 14 m; D = 6 m ; T = 3.5 m. Minimum freeboard height is 947 mm. The ship’s tonnage is 3610,95 GT and has passed Intact Stability (IS) Code Reg. III/3.1 criterias. (2) Economic calculation and analysis such as building cost, operational cost and Break-Even Point (BEP) estimation. The building cost is estimated at Rp 162.302.693.118 and BEP within 56 months with estimated revenue at Rp 2.921.154.559.
