Abstract

Dalam industri minyak dan gas, proses produksi adalah salah satu tahap penting. Dan untuk menunjang proses eksplorasi dan eksploitasi minyak di lepas pantai, diperlukan anjungan lepas pantai. Anjungan lepas pantai (offshore platform) di desain khusus agar dapat mengambil sumber minyak dan gas dari dalam permukaan bumi yang letaknya dibawah permukaan laut. Berdasarkan jenis dan fungsinya, tipe anjungan lepas pantai sudah ada berbagai macam, dan untuk sebuah proyek baru, perlu dilakukan asesmen lebih lanjut untuk menentukan jenis anjungan lepas pantai mana yang paling sesuai. Begitupun dengan proyek yang berada di lapangan Madura, North Processing Facility. Analytical Hierarchy Process (AHP) dipilih menjadi metode pemilihan platform untuk proyek tersebut pada tugas akhir ini. AHP adalah suatu metode pengambilan keputusan untuk menentukan alternatif terbaik berdasarkan kriteria dan subkriteria yang mengandalkan opini para ahli pada bidangnya. Struktur terpilih tersebut akan dianalisis lebih lanjut dengan analisis statis atau inplace untuk memperoleh unity check dari member. Member dengan unity check paling besar kemudian digunakan dalam analisis keandalan dengan Simulasi Monte Carlo. Dari hasil perhitungan AHP, diperoleh alternatif struktur Jacket 3 kaki dengan bobot 0,538, lalu tipe platform Jack up 3 kaki dengan bobot 0,287 dan tipe platform FPSO dengan bobot 0,175. Kemudian unity check of member dari platform terpilih tersebut sebesar 0,742 saat kondisi operasi dan 0,84 saat kondisi badai. Dan dari analisis keandalan diperoleh pada kondisi operasi PoF sebesar 0,53524 dan 0,62614 saat kondisi badai.

In the oil and gas industry, the production process is one of the important stages. And to support the process of offshore oil exploration and exploitation, offshore platforms are needed. Offshore platforms are specially designed to be able to extract oil and gas sources from the earth's surface which are located below sea level. Based on the type and function, there are various types of platforms, and for a new project, further assessment needs to be carried out to determine which type of platform is the most suitable. Likewise with the project in the Madura field, the North Processing Facility. The Analytical Hierarchy Process (AHP) was chosen as the platform selection method for the project in this final project. AHP is a decision-making method to determine the best alternative based on criteria and sub criteria that rely on the opinions of experts in their fields. The selected structure will be further analyzed with static or inplace analysis to obtain the unity check of member. The member with the highest unity check is then used in reliability analysis with Monte Carlo Simulation. From the results of the AHP calculation, an alternative structure of a 3-foot Jacket with a weight of 0.538 was obtained, then a 3-foot Jack-up platform type with a weight of 0.287 and an FPSO platform type with a weight of 0.175. Then the unity check of members from the selected platform is 0.742 during operating conditions and 0.84 during storm conditions. And from the reliability analysis, it is obtained that the PoF operating conditions are 0.53524 and 0.62614 during storm conditions.
