Abstract

Sea transportation accounts for 3% of the global greenhouse gas effect. The International Maritime Organization (IMO) is committed to reducing the impact of greenhouse gases by 50% in 2050—Indonesia is a maritime country with 10.8% of the world's ship register. High traffic has an impact on increased gas emissions. The IMO has made a policy on the Ship Energy Efficiency Management Plan. IMO recommends using Shore Side Electricity to reduce exhaust emissions, namely the use of electricity sources from land will reduce the operation of the ship's generator when berthing.This SSE case study uses the State Ship (KN) Masalembo at the Tanjung Perak Port. Evaluation of the impact of SSE on emission reduction is carried out by calculating electricity and fuel consumption. Based on fuel consumption, the amount of pollutants produced is known. A Descriptive quantitative method is used in this research. Based on the calculation, the electricity demand at 220 Volt voltage is 95,028 watts, and at 380 watts is 276,210 Watts. There are 3 generators on board with different output power. There are: auxiliary engine 1-2, harbour generator, and emergency generator. Each generator has different efficiency and fuel consumption. The Comparison of SSE reduction impact is largest in aux eng 1-2 worth 206,855.13 kg pollutant/ton of fuel. Fuel cost savings of up to 92.57% every year. SSE utilization is a solution for reducing exhaust emissions in the port area. Power generation using renewable energy sources is a recommendation for supporting SSE operations.

Abstract

Ships contribute to CO2 gas emissions. The government's effort to reduce these emissions is by having Onshore Power Supply (OPS) facilities. OPS is a technology that allows ships at anchor to turn off their engines and connect to the local electricity network for electricity supply. Port of Berlian currently has 8 OPS spot managed by PT. Lamong Energi Indonesia. The use of OPS still needs to be examined using valid methods. In this research, researchers use the assessment methodology that has been used at the port of Lisbon regarding this onshore electricity facility type of port where the ship is docked (mooring vessel). In this methodology, the assessment process carried out includes data gathering and data processing processes. Apart from this process, it is necessary to review the character of the port or terminal that we will examine ships that most often use land-based electricity facilities are ships with a size of 1000-2999 GT. The use of land electricity facilities provides cost efficiency of 78%. This land electricity facility is used by General Cargo and Container type ships. These results indicate that the use of land electricity facilities is still inefficient ( 2.7%) and there is a need for further review of the implementation of existing policies.

Abstract

This research focuses on designing an electrical system for unmanned surface vehicles (USV) to ensure optimal performance during survey operations. This USV ship is a catamaran-type ship with a Sonar Deeper depth sensor to know the depth of the water and is equipped with long range (LoRa) as a data transmitter. The USV electrical system design incorporates the use of a 4050 mAh 11.1 V LiPo battery and an iMAX B6AC charger, with evaluations covering battery charging, power consumption, and voltage stability. The trials showed that the battery supported the operation of the USV for approximately 47.8 minutes at a power load of 45.08 Watts. Battery charging showed two main phases: constant current and constant voltage, with a full charge time of approximately 2.7 hours. During operation, voltage consumption showed significant fluctuations, highlighting the need for an electrical system design that maintains voltage stability to improve performance. From the test results, the battery efficiency was found to be 91.29%. These findings emphasize the importance of appropriate component selection and efficient power management to achieve reliable and efficient USV operation. With a deep understanding of the charging characteristics and power consumption, the designed electrical system can ensure more stable USV operation and better performance under various survey conditions.

Abstract

Ships as the main mode of transportation that has a strategic role in trade transportation, the trade supply chain really needs proper operations. The operational of the ship is greatly influenced by the performance of the main engine. One of the critical components of the main engine is the exhaust valve which functions to regulate the release of exhaust gas from the combustion chamber to the exhaust manifold. The research is qualitative, collecting data through observation, documentation, and interviews. The event tree analysis (ETA) method is implemented the sequence of impacts produced by exhaust valve, such as high working temperatures, low engine performance, and standard functions described in the manual book so that leaks can be identified. So, From this analysis, the impacts that are traced sequentially to the performance of the exhaust valve itself can also be found. In addition, a fishbone diagram is used to describe the factors that cause leaks, including human error, managerial deficiencies, neglected inspections, and errors in maintenance techniques. Thus, the right handling can be found to overcome exhaust valve leaks, such as repairs required while the engine is stopped, repeated spare part submissions from ship management, conducting spindle thickness inspections, and improving maintenance techniques as specified in the engine manual book. Proper and effective preventive and handling actions based on the root causes outlined are essential to ensure proper operation of the machine.
