Abstract

In shipyards, human error is a serious problem that can compromise operational effectiveness, productivity, and safety. The effectiveness of shipyard operations still largely depends on human participation, despite the quick advances in automation and technology. In shipyards, human error can result in mishaps, monetary losses, and reputational harm. Finding workable solutions is therefore essential to lowering the possibility of human error. The possibility of human error in shipyards is investigated in this article by first determining the variables that may lead to errors and then estimating the likelihood that they will occur. The Human Error Assessment and Reduction Technique (HEART) is the methodology employed. A technique called HEART is used to assess the degree of human error in a system, which helps to analyze how human errors affect a system's performance. The analysis's findings show that bending and pressing plates are two fieldwork tasks that have a high risk of human error. This study also makes it clear that management’s engagement in resolving human error issues must be proactive. Hands-on training, ongoing safety policy formulation, and encouragement of a happy workplace are just a few ways that management can help lower the possibility of human error.

Abstract

The Thousand Islands is a marine tourism area located around Jakarta, which has several beautiful and charming islands. Many cargo barge decks are not operating because natural resources are starting to decline. One of the innovations to increase tourist attraction is by designing a floating hotel using a 300 ft barge as a supporting facility in the Thousand Islands. Determination of the main size of the ship using the method of comparison of several barge sizes of 300 ft and stability calculations using the A.N-Krylov method with maxsurf software. Obtained ship size LOA = 91.5 m, B = 27.5 m, H = 5.5 m, T = 4.3 m. The superstructure modification has three decks, each deck being 3 m high with a different length. The results of the floating hotel design have a total of 52 rooms that can accommodate 116 visitors. There are superior room types, deluxe rooms and suite rooms and are equipped with other facilities. The floating hotel's safety equipment includes 8 lifebuoys, 188 lifejackets, 4 lifeboats and 8 liferafts. The stability of the floating hotel meets the intact stability criteria of the IMO standard A.749(18) Ch3 - Design criteria applicable to all ships.

Abstract

A shipyard is defined as a place where ships are repaired and built. Where, various risks from the work process i.e., ship repair, hull cleaning, hull coating, etc., exist. Therefore, it is necessary to carry out risk analysis in the work process at XYZ Shipyard. This study uses a descriptive method with a qualitative approach through interviews and based on hazard identification and risk assessment (HIRA) using the AS/NZS 4360:2004 standard to calculate the risk value. Occupational health and safety assessments are carried out to evaluate risks that exist in the workplace intending to eliminate, reduce, and replace sources of risk with safer equipment or processes, or to reduce risks to the health and safety of workers. In this study, we are focused on the three working processes i.e., ship repairment process, hull cleaning, and coating. As a result, it can be concluded that all the risks which occurred in the work process at XYZ Shipyard i.e., ship repair, hull cleaning, and coating process were controlled.

Abstract

Recently, marine big data are significantly increased. If the data are effectively analyzed, it can give an advantage, and we can harness the data that is useful for a decision-maker in maritime industries. The Marine Logistics Database (MLDB) was successfully developed in the previous studies. It was developed by integrating big data into a relational database. By utilizing the extracted data from the developed database (DB), the model of ship allocation will be established. In this study, the main purpose is to develop a ship allocation model that matches the results with the existing ship allocation. In this study, the effectiveness of the allocation model was examined by checking the port constraints, ship specification, and allocation process itself. Moreover, some simulations were executed and discussed to develop new ship allocation and analyze the effective ship specification.

Abstract

Engine emissions of ships have been highly concerned in the last decades. Most of the current ship operations worldwide are powered by the combustion engine. Advance ship powering is still on research and hard to implement directly. High cost in the application is the main issue. Meanwhile, the fuel engineering approach is proposed in the recent research to advance engine combustion, thus increasing the combustion efficiency and lowering the emissions target. This study aims to evaluate the development trend on the fuel efficiency technique to lower ship emissions. Emissions management, fuel conversion, and power conversion are the most research focus to improve fuel efficiency. However, implementing some of that research is still hard on ship operation. Technical and economic issues are the main reason. Moreover, fuel efficiency on ships is still highly based on management. Low cost, new combined fuel without separation, and less fuel treatment technology are proposed to avoid confusion on fuel consumption in the near future.

Abstract

Recently, the global marine logistics industry has changed significantly because of the global movement of goods. Where the amount of available data and attention paid to extensive data analysis in various topics exponentially grows, it is possible to obtain vast amounts of marine BD. However, the collection of BD groups is difficult to organize and frequently redundant. This is why the database can be so important. If these BD are effectively utilized, great innovation can be achieved in the marine industry. In this study, we develop a marine logistics database to ship basic planning support in the future. The database under study consists of BD sets, i.e. port, ship, route, international trade, and ship operation information from automatic identification system data. As a result, the relational database was developed. The effectiveness of the database is evaluated and extracted data from the database necessary for ship basic planning is discussed.

Abstract

Cavitation is a detrimental phenomenon to ship operations because it causes many losses. It caused some effects i.e decreased propeller efficiency, damaged propeller material, lower ship speed, vibration, and extreme noises. In that regard, this research conducts cavitation analysis on controllable pitch propeller (CPP) by varying number of blade i.e. 3, 4 and 5 blades; diameter i.e. 30, 40 cm and 50 cm; also pitch i.e 0.4, 0.6 and 0.8. The research method is carried out by the author in this study by conducting a simulation method based on the CFD approach. The simulation process consists of 3 stage-post processor, solver manager, and post-processor. From the simulation based on the CFD approach result, it was found that propeller rotation has an effect on the pressure ratio value. As the propeller rotation increase, the value of the pressure ratio will increase as well. The value of the pressure ratio in propeller design affects the cavitation area that occurs in the propeller. The percentage of the cavitation area on the propeller has an increasing tendency with the number of blades, rotation, and pitch. On the propeller with diameter 300 mm, 3 blades, pitch 0.8 at rotation 125 rpm no indication of cavitation, then it increases to 1.41% at rotation 175 rpm and keeps getting higher at rotation 225 to be 4.22% from total propeller expanding area. Whereas at rotation 225 rpm and pitch 0.4 is 3.38 %, then it becomes 3.85 % at pitch 0.6, which is getting bigger at pitch 0.8 that is 4.22 %.
