Abstract
Dalam Tugas Akhir ini dilakukan Risk Assessment terhadap saluran pipa gas ekspor Amerada Hess Limited (Indonesia—Pangkah) pada zona III akibat aktivitas nelayan pencari kerang dan kepiting dengan menggunakan garit (traw/). Untuk mematuhi Keputusan Menteri Pertambangan dan Energi Nomor 300.K/38/M.PE/1997, untuk kedalaman dasar laut kurang dari 13 meter, maka saluran pipa harus ditanam dengan kedalaman sekurang-kurangnya 2 meter di bawah permukaan dasar laut. Akan tetapi karena dasar laut keras (berbatu), sehingga tidak memungkinkan untuk dilakukan pemendaman. Sehingga harus dilakukan analisa resiko untuk menetapkan langkah pengamanan tambahan. Pendekatan untuk memperkirakan frekuensi menggunakan Event Tree Analysis (ETA). Sedangkan untuk memperkirakan konsekuensi menggunakan standard DNV RP Fi11, dan DNV RP F 107 yang menggunakan metode Risk Matrix untuk menilai apakah resiko dapat diterima atau tidak. Untuk memeriksa perhitungan konsekuensinya menggunakan bantuan program autopipe. Dalam Tugas Akhir ini diberikan 3 metode alternatif perlindungan tambahan untuk saluran pipa beserta perkiraan biayanya antara lain U-type pre-cast (metode I) sebesar Rp 5.490.490.000, massiv mess pre-cast (metode TI) sebesar Rp 1.248.315.000, dan Z-type pre-cast (metode III) sebesar Rp 8.962.710.000. Dengan tingkat pengamanan yang relatif sama, metode U-type pre-cast lebih menguntungkan karena lebih murah dari kedua metode yang lain.

This final project addresses the Risk Assessment of the export gas pipeline at zone III of Amerada Hess Limited (Indonesia-Pangkah) due to trawl fishing activities. Reffering to the Decree of the Minister of Mines and Energy No.300.K/38/M.PE/1997, in the case of seabeds depth is less than 13 meters, the pipeline should be buried at the minimum depth of 2 meters beneath the seabed. Due to the sandstone soil condition, however, trenching is not possible. Consequently, the risk assessment must be carried out to assess the need of additional pipeline protection. The method in predicting frequency is performed by Event Tree Analysis (ETA). DNV RP F111 and DNV RP F 107 are use to predict the consequence through evaluation of risk matrix to verify whether or not risk is within the acceptance criteria. As for evaluate the calculation of consequence is use Autopipe program. This Final Project provides 3 alternative methods of pipeline protection along with cost estimation of U-type pre-cast “3 method) amounting to Rp 5.490.490. 000, massiv mess pre-cast rang method) amounting to Rp 7.248.315.000, and Z-type pre-cast (3 method) amounting to Rp 8.962.710.000. With the same relative safety level, U-type pre-cast method provides more benefit than the other methods.
