Abstract

Penelitian ini bertujuan membuat program simulasi komputer sistem propulsi dinamis untuk penilaian kemampuan dan perilaku manuver berhenti kapal berdasarkan standar manuver IMO. Program simulasi komputer mengembangkan algoritma DTGM yang diadaptasikan untuk gerak manuver kapal tiga derajat kebebasan. Algoritma program simulasi komputer mengembangkan formula sebelumnya dengan adanya penambahan faktor konversi pada lateral force dan yaw moment. Evaluasi penilaian kemampuan manuver berhenti kapal telah dilakukan dengan hasil jangkauan lintasan pada kondisi Full Sea Ahead (FSAH) adalah 15.1 L, Full Ahead (FAH) adalah 12.4 L, dan kondisi Half Ahead (HAH) adalah 9.18 L. Evaluasi perilaku berhenti kapal mendapatkan hasil side reach masing-masing pada kondisi FSAH, FAH, HAH adalah 0.0001611 L, 0.0001633 L, dan 0.0001626 L. Nilai head reach yang diperoleh sama dengan jangkauan lintasan yang telah dievaluasi pada penilaian kemampuan manuver berhenti kapal untuk semua kondisi dengan waktu berhenti kapal adalah 11.5 menit (FSAH), 10.28 menit (FAH), dan 8.65 menit (HAH). Berdasarkan standar manuver IMO dengan maksimal jarak jangkauan lintasan sebesar 15 L, pada kondisi FSAH belum memenuhi kriteria, sedangkan pada kondisi FAH dan HAH telah memenuhi kriteria. Berdasarkan hasil penilaian kemampuan dan perilaku berhenti kapal program simulasi komputer sudah sesuai dengan trendline dari benchmark data yang telah direkomendasikan oleh ITTC. ===================================================================================================== This study aims to create a computer simulation program for a dynamic propulsion system for assessing the capability and behavior of ship stopping maneuvers based on IMO maneuvering standards. The computer simulation program developed a DTGM algorithm adapted for ship maneuvers of three degrees of freedom. The computer simulation program algorithm developed the previous formula by adding a conversion factor for the lateral force and yaw moment. The evaluation of the ship's stopping maneuverability assessment has been carried out with the results of the trajectory range in Full Sea Ahead (FSAH) conditions of 15.1 L, Full Ahead (FAH) of 12.4 L, and Half Ahead (HAH) conditions of 9.18 L. Evaluation of ship stopping behavior obtained results side reach in conditions of FSAH, FAH, HAH are 0.0001611 L, 0.0001633 L, and 0.0001626 L, respectively. The head reach value obtained is the same as the trajectory range that has been evaluated on the ship's stopping maneuverability assessment for all conditions with a ship stop time of 11.5 minutes (FSAH), 10.28 minutes (FAH), and 8.65 minutes (HAH). Based on the standard IMO maneuver with a maximum trajectory distance of 15 L, the FSAH condition does not meet the criteria, while in the FAH and HAH conditions it meets the criteria. Based on the results of the assessment of the capability and behavior of stopping ships, the computer simulation program is in accordance with the trendline of benchmark data recommended by ITTC
