Abstract

PLTAL adalah salah satu struktur terapung atau platform yang digunakan untuk kegiatan eksplorasi energi laut di lepas pantai. Desain dari Pembangkit Listrik Tenaga Arus Laut (PLTAL) secara umum terdiri dari turbin dan mooring system untuk menjaga platform tetap pada posisinya akibat beban lingkungan, angin, aurs, dan gelombang. Penelitian yang dikerjakan penulis, yaitu melakukan analisa gerakan PLTAL pada arah gelombang 0, 45, 90, 135, dan 180 derajat pada gerakan Surge, Sway, Heave, Roll, Pitch dan Yaw. Selanjutnya dilakukan Mooring Line pada PLTAL guna mengurangi gerakan kapal saat berada ditengah laut. Dari hasil yang didapatkan pada simulasi keadaan free floating, nilai surge tertinggi 7.03 arah gelombang 0 dan 180°, Sway terbesar 7.03 m/m, Heave 1.61 m/m, Roll 14.36 m/m, Pitch 27.93 deg/m, dan Yaw 11.45 deg/m. Kemudian hasil tegangan tali tambat bahan polyester, wire rope, dan chain dapat memenuhi aturan Safety Factor dari API RP 2SK. Dalam mengurangi gerakan ponton akibat beban lingkungan, didapatkan bahan chain karena memiliki frekuensi pengurangan gerakan yang lebih banyak.

PLTAL is a floating structure or platform used for offshore marine energy exploration activities. The design of the Ocean Current Power Plant (PLTAL) generally consists of a turbine and a mooring system to keep the platform in position due to environmental loads, wind, currents, and waves. The research carried out by the author is to analyze the PLTAL movement in the wave directions of 0, 45, 90, 135, and 180 degrees in the Surge, Sway, Heave, Roll, Pitch and Yaw movements. Furthermore, a Mooring Line is carried out on PLTAL in order to reduce the movement of the ship when it is in the middle of the sea. From the results obtained in the free floating state simulation, the highest surge value is 7.03 wave direction 0 and 180 °, largest Sway 7.03 m/m, Heave 1.61 m/m, Roll 14.36 m/m, Pitch 27.93 deg/m, and Yaw 11.45 deg. /m. Then the results of the tension of the mooring rope made of polyester, wire rope, and chain can meet the Safety Factor rules of API RP 2SK. In reducing the movement of the pontoon due to environmental loads, chain material is obtained because it has a higher frequency of movement reduction.
