Abstract

English

OT ship. Skylie is a type of tanker produced by PT. Samudra Marine Indonesia, in its construction, applies a keel cooler as a cooling device for the main engine propulsion of ships. This keel cooleris one of the new types of heat exchangers which is applied in the field of shipping. A cooling system using a keel cooler is a closed-circuit cooling system that is installed externally on the hull below the waterline. This study aims to determine the overall heat transfer value and the effect of changes in ship power/torque on the effectiveness of the keel cooler-type heat exchanger. The analysis uses two methods, namely CFD analysis and simulation using the Ansys CFX R20 application. Based on the results of calculations on several ship power/torque conditions, the largest heat transfer value is obtainednamely 5.599 x 10 5 W at 100% power condition and the lowest value is 5.055 x 105 W at 10% power condition. Meanwhile, the highest effectiveness value is 79.985% and the smallest value is 79.839%. So it can it was concluded that the use of the keel cooler on the OT ship. Skylie has met the standard value of effectiveness for a heat exchanger that is equal to 50%.

Bahasa Indonesia

Kapal OT. Skylie merupakan salah satu jenis kapal tanker yang diproduksi oleh PT. Samudra Marine Indonesia, dalam pembangunannya mengaplikasikan keel cooler sebagai alat pendingin mesin utama penggerak kapal. Keel cooler inimerupakan salah satu alat penukar kalor tipe baru yang diaplikasikan di bidang perkapalan. Sistem pendingin denganmenggunakan keel cooler merupakan salah satu sistem pendingin sirkuit tertutup yang dipasang secara eksternal pada lambung kapal di bawah permukaan air. Penelitian ini bertujuan untuk mengetahui nilai perpindahan panas menyeluruhdan pengaruh dari perubahan power/torque kapal terhadap efektivitas penukar kalor tipe keel cooler. Dalam analisa menggunakan dua metode, yaitu analisis dan simulasi CFD dengan menggunakan aplikasi Ansys CFX R20. Berdasarkan hasil perhitungan pada beberapa kondisi power/torque kapal diperoleh nilai perpindahan kalor terbesaryaitu 5,599 x 105 W pada kondisi power 100% dan nilai terendah sebesar 5,055 x 105 W pada kondisi power 10%. Sementara itu untuk nilai efektivitas terbesar yaitu 79,985% dan nilai terkecil sebesar 79,839%. Sehingga dapat disimpulkan bahwa penggunaan keel cooler pada kapal OT. Skylie sudah memenuhi nilai standar efektivitas untuk sebuahheat exchanger yaitu sebesar 50%.
