Abstract

Rancang bangun sistem kendali Dynamic Positioning System (DPS) pada Model Semi-Submersible Platform menggunakan Fuzzy Logic Control merupakan sistem kendali otomatis untuk mempertahankan posisi dan arah hadap platform. Sistem DPS yang diterapkan pada platform yang beroprasi dikedalaman lebih dari 300 m dapat meningkatkan efektifitas dan nilai ekonomis dibandingkan dengan menggunakan sistem mooring dengan jangkar. Diharapkan platform dengan kontrol Fuzzy mampu merepresentasikan respon pergerakan platform terhadap pergeseran posisi dan arah hadap platform. Untuk mempertahankan posisi dan arah hadap platform, digunakan sensor GPS dan Compass untuk memberikan feedback pada 4 motor thruster dan 4 motor servo. Sistem DGPS (Dfferential Global Positioning System) digunakan untuk mengurangi nilai eror sensor GPS dengan menambahkan titik refensi GPS yang terdapat didarat. Pengujian yang dilakukan untuk mengetahui respon platform adalah dengan cara menggeser platform pada empat skenario pergeseran yaitu pergeseran Surgee, Sway, Yaw, serta kombinasi antara Surge dan Sway pada jarak 2m dari Set Point. Hasil yang didapatkan dari pengujian adalah platform mampu merepresentasikan respon pergerakan dari pergeseran yang dilakukan untuk kembali menuju ke posisi dan sudut heading awal. Nilai eror jarak dari posisi awal dapat mencapai 0.22 m dengan rata-rata nilai eror 0.55m dan rata-rata eror sudut heading adalah 8.33°, serta respon waktu tercepat adalah 23 detik pada rspon pergerakan mundur dengan rata-rata respon waktu pergerakan dari berbagai arah adalah 36 detik.

Design of the Dynamic Positioning System (DPS) control on the Semi-Submersible Platform Model using Fuzzy Logic Control is an automatic control system to maintain the position and heading of the platform. The DPS system that is applied to platforms that operate in depths of more than 300 m can increase the effectiveness and economic value compared to using the mooring system with anchors. It is expected that Fuzzy control platforms are able to represent the response of platform movements to shifting positions and direction to the platform. In order to maintain the position and heading of the platform, GPS sensors and Compass are used to provide feedback on 4 thruster motors and 4 servo motors. The DGPS (Differential Global Positioning System) system was used to reduce the error value of a GPS sensor by adding GPS reference points found on the ground. The test to find out the response of the platform is to shift the platform to four shifting scenarios, namely shifting Surge, Sway, Yaw, and a combination of Surge and Sway at a distance of 2m from Set Point. The results obtained from the test were that the platform is able to represent the movement response from the shift made to return to the position and angle of the initial heading. The value of eror distance from the initial position can reach 0.22m with an average error value of 0.55m and the average error of the heading angle is 8.33 °, and the response of the fastest time is 23 seconds in the backward response with the average response time of movement from various directions is 36 seconds.
