Abstract
Dalam tugas akhir ini telah dilakukan kajian mengenai analisa resiko pada kebocoran pipa bawah laut dengan menggunakan metode hybrid risk analysis. Kajian diawali dengan menentukan ruang lingkup analisa menggunakan fault tree analysis yang kemudian bisa ditentukan main event dari kegagalan kebocoran pipa bawah laut hingga menuju basic event-nya. Setelah menentukan ruang lingkup analisa maka dilanjutkan dengan menghitung besar frekuensi tiap kejadian dengan menggunakan quantitative method. Pada perhitungan ini diketahui besar frekuensi basic event melalui data dari paper scientific programming dan scientific research kemudian dihitung frekuensi akibat dari kejadian tersebut menggunakan Boolean Equation hingga didapatkan besar frekuensi dari kegagalan akibat kebocoran pipa bawah laut sebesar 0.0013. Setelah mengetahui berapa besar probabilitas kegagalan, dilanjutkan dengan menentukan berapa besar dampak atau konsekuensi dari kegagalan tersebut. Konsekuensi kegagalan ditentukan berdasarkan dampaknya terhadap keselamatan, lingkungan, dan juga bisnis. Pada penentuan besar dampak dengan qualitative method digunakan kuisioner wawancara ke beberapa responden. Setelah mendapatkan hasil wawancara kuisioner maka dihitung mean dari hasil kuisioner untuk menentukan berapa besar dampak dari kegagalan tersebut berdasarkan keselamatan, lingkungan, dan bisnis. Setelah mengetahui berapa besar probabilitas dan konsekuensi dari kegagalan tersebut, maka tentukan posisi zona resiko pada matriks resiko yang mengacu pada DNV RP-G101. Setelah mengetahui posisi zona resiko, maka bisa ditentukan bagaimana cara mengendalikan resiko berdasarkan pendekatan sebab-akibat.
=================================================================
In this final project has been conducted a study on risk analysis on subsea pipeline leakage by using hybrid risk analysis method. The study begins by determining the scope of the analysis using fault tree analysis which can be determined the main event of the leakage failure of subsea pipeline until the basic event. After determining the scope of the analysis then proceeded to calculate the frequency of each event using the quantitative method. In this calculation is known the frequency of basic event through data from scientific paper programming and scientific research and then calculated the frequency result of top event using Boolean Equation until we get the frequency of failure due to leakage pipelines for 0.0141213. After knowing how big the probability of failure, followed by determining how much impact or consequence of the failure. The consequences of failure are determined based on their impact on safety, environment, and business. In the determination of the impact with the qualitative method using questionnaires interviews to some respondents. After obtaining the result of questionnaire interview then calculated the mean of the questionnaire result to determine how big impact of the failure is based on safety, environment, and business. After knowing how big the probability and consequences of the failure, then determine the position of the risk zone on the risk matrix that refers to DNV RP-G101. After knowing the position of the risk zone, it can be determined how to control risk based on cause-effect.
