Desain Fender Pada Condensate And Sulphuric Acid Berth PT. Pertamina – Medco E&P (Job PMTS) Di Senoro Block Project

Laporan ini akan menjelaskan selengkapnya tentang analisa dan desain sistem fender pada dermaga PT. Pertamina – Medco E&P (JOB PMTS). Fender adalah suatu bagian dari struktur dermaga yang berfungsi untuk meredam energi tumbukkan kapal kemudian mentransfer energi tersebut menjadi reaksi pada struktur dermaga. Analisa metode elemen hingga menggunakan ANSYS diterapkan pada sistem fender tipe cell dengan beban terpusat oleh energi berlabuh kapal. Pemilihan sistem fender berdasarkan perhitungan sistem penyerapan energi pada beban dan analisa defleksi maupun tegangan. Software ANSYS dipilih dikarenakan software ini memiliki fitur yang baik dalam menghitung energi potensial material. Sistem fender dengan diameter dan tinggi 2 meter terdiri atas 2 material yaitu Baja ASTM A36 pada panel fender dan Styrene Butadiene Rubber pada karet fender. Styrene butadiene rubber didesain berdasarkan pada elastomer sample Yeoh 3rd Order dengan kekuatan tarik 16 MPa. Hasil yang didapat dari penelitian ini adalah analisa tegangan dan deformasi sistem fender untuk mengetahui kekuatan struktur. ================================================================================================ This report will describe complete investigations of the analysis and design of a proposed fender system for PT. Pertamina – Medco E&P (JOB PMTS) berth. Fendering is basically the interface between a vessel and the berth facility. This medium serves to absorb a certain portion of the kinetic energy of a vessel without damage to the vessel and the waterfront structure [1]. Finite elements analysis using ANSYS were performed on a cell fender system subjected to impact load caused by a vessel collision. The impact load was converted into equivalent static load. The selection of the most efficient fender system is based on the principle on energy absorption of the system to the impact load and stress analysis deflection. The ANSYS program was chosen to perform the analysis because it has an excellent feature that calculates the potential energy of the material. Fender system with 2 meter of diameter and height consist 2 material properties such as structural steel ASTM A36 for fender panel and styrene butadiene rubber for fender rubber. Styrene butadiene rubber was designed according to the elastomer sample Yeoh 3rd Order with 16 MPa tensile strength. The conclusion of this investigation was the stress and deformation analysis for the fender system strucure analysis
