Abstract

Every ship project would not be apart from risk and uncertainty issues. The inappropriate risk assessment process would have long-term impact, such as financial loss. Thus, risk and uncertainties analysis would be a very important process in financial feasibility determination of the project. This study analyzes the financial feasibility of 17,500 LTDW tanker project. Risk and uncertainty are two differentiated terminologies in this study, where risk focuses on operational risk due to shipbuilding process nonconformity to shipowner finance, while uncertainty focuses on variable costs that affect project cash flows. There are three funding scenarios in this study, where the percentage of funding with own capital and bank loan in scenario 1 is 100% : 0%, scenario 2 is 75% : 25%, and scenario 3 is 50% : 50%. Monte Carlo simulation method was applied to simulate the acceptance criteria, such as net present value (NPV), internal rate of return (IRR), payback period (PP), and profitability index (PI). The results of simulation show that 17,500 LTDW tanker project funding by scenario 1, 2 and 3 are feasible to run, where probability of each acceptance criteria was greater than 50%. Charter rate being the most sensitive uncertainty over project's financial feasibility parameters.

Abstract

This study discusses about safety on board especially during fire condition. During fire, all passengers and crew had to beevacuated into safe place. The study observe at 1200 GT passenger ships, a typical ship which have small dimension vessel characteristic but able to carry passenger more than four hundred persons and also could containt cargo. When the ship was on fire at any circumstances that requires passengers need to be evacuated, it’s obvious that there will be a buildup of passengers when passing through stairs and corridors. The calculation use to estimate evacuation time required based on the IMO guidelines. Studies continued by creating evacuation simulation using Agent-Based Modeling, a simulation modeling that assume human being as an agent that has characteristics resemble to real state of motion. The comparation between the two methods, calculation and simulation are both using two scenarios, day and night conditions. Result show that the simulation generates evacuation time shorter than the calculation method. In the numerical calculation takes 689 seconds and 1595 seconds in day and night conditions, while in the simulation process takes 548 seconds and 1374 seconds in day and night conditions sequentially. This studies also followed by fire modeling study that aims to determine the spread of heat and smoke produced from fire. On the condition of fire, smokewords. production will interfere passengers in the evacuation process. The evacuation time becomes longer and estimates the potential victims affected by fire.

Abstract

International Maritime Organization (IMO) has recommended the implementation of Automatic Identification System (AIS) to improve the safety of navigation at marine traffic area. Based on regulation, IMO requires AIS to be fitted aboard all ships of 300 gross tonnage and upwards engaged on international voyages, cargo ships of 500 gross tonnage and upwards not engaged on international voyages and all passenger ships irrespective of size. The function of the AIS is to make communication between ship to ship and communication between ship to the port or land area. In this study, the study area is the Malacca Strait. Malacca Straits is the strait categorized as high risk level. Malacca straits is also busy area for maritime transportation because it is an area for international transportation lines. Many captains feel anxious and cautiously when passes through the strait. AIS receiver was used in this study which has been installed at Universiti Teknologi Malaysia by Kobe University Japan. Using AIS receiver, the current condition of the ship in the Malacca Straits area can be monitored properly. In addition, the data recorded on the AIS receiver can be used for research to enhance safety of navigation.
