Liquefied Natural Gas production processes involve many high profile control systems and equipments that costing a vast amount of investment. Any mistakes in the management decision to select the resources and equipments will cause serious problem aftermath and it will be difficult to meet the expected output. Production processes play very important rules in Liquefied Natural Gas Supply Chain and integration with well models (under water process), storage models, transportation model and receiving terminal models. The main focuses of this paper are to simulate production and storage capacities of Rounded-Shape Floating Liquefied Natural Gas by considering the capacity of every single process and utilization of equipments used and storage design. Simulation modeling can be used as controlling and decision making tool with associated factors such as Front-End Engineering Design rate, capacity of every process and storage design capacity.

Demand for traditional ship in Indonesia is very high, because the ship is used of fishermen for catching fish as a livelihood. Shipbuilders as manufactures play an important element in building safety and good traditional wooden ships. In the production process, the shipbuilders must be has proper quality control system, in order to match with the owner specification, regulation, and statutory. Therefore, this article discusses about quality control system in traditional ship production process. The research were conducted by direct survey to traditional shipbuilders in Kepulauan Riau-Indonesia by inspect some ships by visual eyes only. From the survey, it was found many discrepancies occur, such as the use of wood has many defects, knur, knot and cracks. In addition, the wood concatenation process is not perfect, which can cause leakage. From the study, the shipbuilders should conduct quality control using other tools instead of visual technique only.

This research is targeted to apply the numerical method in the ship’s propeller design and analysis. In this thesis, the Quasi Continuous Method developed based on lifting surface theory is applied to predict the performance of propeller in open water condition. To fulfill the desire of industry to obtain an accurate, fast and low cost solution in propeller design, this design and analysis process is proposed made by computer programming software. This is because fast development on computer technology provided the possibility to carry propeller design task by using numerical software. In this research, the Quasi Continuous Method for propeller performance evaluation is applied. This method allows the fast propeller prediction process and low computer cost required. In this research, the VLCC ship model and it propulsion system is preselected. The propeller of the VLCC ship is designed and analyzed using the propeller database system in the numerical software OCARI S-Power. Next, the function of Quasi Continuous Method in the software is applied to predict the open water performance of the designed propeller. Finally, the appropriate propeller model and it dimension is determined in this research. In conclusion, application of numerical software in propeller design is an advance solution where this solution is relatively high efficient compare to the traditional method.

Traditional ship-building is still widely practiced in Indonesia. Every province and regions have different characteristics in the design and production process of the traditional ships. The production process and procedure of traditional ship is far from the influence of advance technology. This study presents traditional shipbuilding process in the Kepulauan Riau, Indonesia. Survey three traditional shipbuilders in Bintan island, Mana Island, and Kelong island are carried out to get the production process by interviewing master and taking photo for documentation as case study. It is found that strip plank method with both fire and pressing techniques is used in production traditional ship in Kepulauan Riau, Indonesia. L-Joint technique is applied between keel-stem frame and T-joint technique between keel-stern-post.
