Abstract

AHTS (Anchor Handling Tug Supply) vessel is specifically vessel that designed to support activities, offshore drilling work for oil and natural gas from preparation, supply of cargo to production [1]. As a support vessel for offshore operations in carrying out its functions, this ship is of course equipped with a main engine. The main engine on board is the main propulsion engine so that the ship can run, maneuver and move anywhere to carry out its operations [2], so the performance of the main engine on board is very important. There are various types, maker and brands of main engines commonly used on AHTS vessel. In general, AHTS ships are equipped with 2 main engines, many ships use 1 main engine, and for crew boat types to support offshore operations, some are equipped with 4 main engines. But it is very rare to find a ship that uses 3 main engines. This study aims to analyze the performance of three main engines of the AHTS vessel Christos LVII. This research is a survey research combined with library research by examining several sources and direct observation and analysis [3]. The results showed that: exhaust gas temperature, lubricant pressure and temperature, coolant temperature, gearbox oil pressure, air pneumatic and air starting pressure also fuel pressure during 1 month is always in normal condition and no deviations ever occurred. The performance of the main engine which is 4 years old is still good and normal according to standard parameters during the vessel's first sea trial. The function of the main engine on the vessel AHTS LVII is very important because apart from being the prime mover of the ship's propeller shaft, the main engine is also used to drive the shaft generator which produces electric current to be used to run all of equipment on board.

Abstract

An important aspect that needs to be considered in an effort to reduce the use of fuel on a ship is the planning of the ship's propulsion components (propulsor). The propulsion of traditional fishing boats in the Mayangan Probolinggo area is usually based only on market readiness and compatibility with the boat shaft used, without regard to the drag and thrust factors produced by the boat. So it is suspected that there are many deficiencies, especially in terms of thru). Efforts to increase the thrust of the ship can be done by installing a tool in the form of a cort nozzle called an Energy Saving Device (ESD) on the propeller. In this research, we will examine the selection of the Kort nozzle and analyze the model in order to obtain the shape of the Kort nozzle which can increase thrust on purse seine fishing vessels with variations in selecting the type of Kort nozzle using the Kort nozzle Shuskin type B, Shushkin type C and Kort nozzle. type 37. Analysis was carried out by simulation method using Computational Fluid Dynamic (CFD) software. The simulation results of fluid dynamic (fluent) computing software show that each model of the ship with the cort nozzle being analyzed experiences an increase in thrust from the application of the cort nozzle. The highest thrust value occurred on ships with Kort nozzle 37 of 8.1468 kN, while for ships with Kort nozzle Shuskin type B of 8.0102 kN. For the lowest thrust value on a ship with a Shuskin nozzle cort type C with a value of 7.8741 kN. So it was concluded that from several variations of the ship found on the ship model with a nozzle 37, the most optimal thrust was obtained. because the thrust force increased 16.1%.

Abstract

Minyak berat sejenis Heavy Fuel Oil (HFO) memiliki karakteristik berwarna hitam, mengandung partikel padat dan residu, pada suhu rendah sangat kental seperti bitumen. Nilai density HFO berkisar antara 0.92-0.99 kg/L dengan kekentalan yang ada dipasaran 180 dan 380 Cst. Perbedaan tempat bunker seringkali berakibat pada perbedaan technical data bahan bakar yang disuplai ke kapal. Efek yang sering terjadi dari perubahan nilai density adalah terganggunya proses treatment pada purifier. Penurunan efisiensi pengisian HFO service tank karena overflow pada purifier merupakan masalah utama yang sering timbul karena nilai density. Berdasarkan fenomena yang terjadi pada proses purifikasi Heavy fuel Oil pasca bunker maka perlu dilakukan studi dalam menentukan gravity disc pada FO purifier. Studi dilakukan dengan tujuan untuk memberikan solusi kepada engineer yang bertugas di kapal-kapal niaga apabila terjadi masalah serupa. Penelitian dilakukan menggunakaan metode studi kasus terhadap permasalahan riil yang terjadi di atas kapal. Asumsi yang digunakan dalam memecahkan persoalan dengan membatasi tangki tempat proses pencampuran di settling tank. Bahan bakar HFO tersisa dalam storage tank adalah 0%, sedangkan bahan bakar tersisa di settling tank 4 KL dengan specific gravity 0.993 kg/L dari total volume 10 KL. HFO yang disuplai saat bunker dengan specific gravity 0.925 kg/L. Studi yang dilakukan mendapatkan hasil gravity disc yang sesuai untuk HFO dengan specific gravity 0.993, 0.975 dan 0.925 kg/L berturut-turut 66, 75 dan 78 mm. Temperatur pemanasan 80 dan 90OC tidak mempengaruhi ukuran gravity disc. Kinerja purifier dapat ditingkatkan dengan mencegah overflow melalui penentuan gravity disc yang sesuai.

Abstract

Kinerja pelayanan operasional pelabuhan dapat di ukur dengan berbagai indikator. Salah satu indikatornya adalah Waiting Time atau waktu tunggu kapal. Waiting Time dan approach Time di hitung sejak waktu kapal tiba di pelabuhan dan mengajukan permohonan tambat sampai dengan mendapatkan pelayanan pandu menuju ke tambatan. Adanya kelambatan Waiting Time dan Approach time dapat menyebabkan kerugian pada setiap kapal dan cukup merugikan bagi pengguna jasa. Tidak hanya membengkaknya biaya, juga akan berdampak pada Waiting Time dan Approach time kapal lainnya. Oleh karena itu untuk mengantisipasi terjadinya Waiting Time dan Approach Time yang lama bagi kapal-kapal yang akan bersandar di pelabuhan atau dermaga, PT Pelindo Multi Terminal Tanjung Intan Cilacap dan Kantor Kesyahbandaran dan Otoritas Pelabuhan Kelas II Cilacap terus berupaya melakukan evaluasi dengan menjaga kinerja pelayanan operasional agar dapat memberikan pelayanan efektif dengan menjaga antrian kapal yang akan sandar dan kapal yang akan keluar, apa yang dilakukkan oleh PT Pelindo Multi Terminal Tanjung Intan Cilacap dan Kantor Kesyahbandaran dan Otoritas Pelabuhan Kelas II Cilacap pada periode tahun 2022 sangat efektif dan telah berjalan dengan baik, dilihat dari Waiting Time dan Approach Time yang dibawah standar yang telah ditetapkan.

Abstract

This research aims to analyze the efficiency of ship operational costs obtained by using dock electricity facilities, which are used as a substitute for using Auxiliary Engines (auxiliary engines), which use fuel oil. The research method used was a mixed method (a combination of qualitative and quantitative). The analysis technique used is cost-benefit analysis (CBA) by comparing fuel oil and shore connections. The analysis results show that using shore connections can reduce ship operational costs by IDR. 6,016,349,488 / year in terms of efficient use of fuel costs, while regarding the reliability of the Auxiliary Engine (AE), the efficiency is up to Rp. 1,903,000,000/ year. After using a shore connection as a substitute for AE, which uses fuel, there will be no damage to the AE, and it can reduce ship repair costs. The use of electricity facilities via shore connection can also support the achievement of the government program, namely Go Green Port (Environmental Friendly), by reducing air pollution from ship exhaust gases as an implementation of MARPOL Annex VI and implementing Permenhub regulation number 29 of 2014 article 37 concerning pollution prevention maritime environment. However, the disadvantages of using shore connections are that the investment costs required for installing cable connections on ships are quite large, and there is an increase in the cost of electricity usage, which is directly proportional to the increase in government electricity rates every year.

Abstract

PT Indo Container Lines is an international transportation firm that offers import/export, stevedoring, freight forwarding, and agency services. The investigation of ship berthing handling at PT Indo Kontainer Sarana BUP Multipurpose Terminal is the primary focus of this study. There are a number of underlying issues that need to be addressed in this study, including: the nature of the process by which container delays occur during ship berthing; the nature of the factors that contribute to such delays; the nature of the impact that results from such delays; and the nature of the agent's efforts to overcome such delays. The purpose of this study is to find ways to reduce the time it takes for ships to dock, which would otherwise cause the consignee to wait longer for their shipment and result in higher Terminal Handling Charges (THC). Ship berthing procedures and container loading and unloading operations at storage facilities for stacked cargo are included. This study employs the descriptive research approach and gathers its data via observation, interviews, documentation, and a review of the relevant literature. According to the study's findings, the problem with the MV Icon Corintus's berth might be solved if the ships, agents, and loading/unloading procedures all worked together more efficiently. This is done so that BUP PT Indo Kontainer Sarana doesn't have to pay extra to deal with ships parked at the port, disassemble containers, and stack them. Agents are responsible for docking ship operations, such as maintaining damaged engines or defective loading and unloading equipment.
