Analisa Perencanaan Mooring System Pada Floating Platform Pembangkit Listrik Tenaga Arus Laut Dengan Menggunakan Metode CFD (Computational Fluid Dynamics)

Abstract

Floating platform pada pembangkit listrik tenaga arus laut membutuhkan stabilitas yang baik untuk melawan gelombang laut, arus laut, angin, serta gaya luar lainnya. Stabilitas dari Floating platform sangat dipengaruhi oleh mooring system yang dipilih. Mooring system yang tepat akan mengurangi derajat gerakan kebebasan (Surge, Sway, Heave, Pitch, Sway, dan Roll) pada derajat gerakan kebebasan dapat dilihat melalui grafik RAO dan spectrum Response. Mooring System yang aman, effisien dan ekonomis harus mempertimbangkan jumlah line, jarak antar line, diameter line, material line, serta tension yang dapat ditahannya. Pemilihan mooring system yang aman, efektif dan ekonomis mutlak hukumnya agar menjaga stabilitas Floating platform sehinga semua komponen peralatan yang berada diatas Floating platform dapat berkerja secara optimal. ======================================================================================================= Floating platform of ocean current power plant requires good stability against sea waves, ocean currents, wind and other external force. Stability of Floating Platform is greatly influenced by the selection of mooring system. The precise selection of mooring system will reduce the degree of free movement (Surge, Sway, Heave, Pitch, Sway, and Roll) on Floating Platform. Degree of free movement can be observed by RAO and Spectrum response. Mooring system that are safe, strong, effective and economic must consider the number of line, line spacing, diameter of line, material of line, and the tension that can be hold. Selection of mooring systems that are safe, effective and economic are absolutely required in order to maintain the stability of Floating Platform so that all components of the equipment which are above Floating Platform can operates optimally
