Modeling and control of ballast system to improve stability of catamaran boat

Ballast system is a system which works to keep the ship to be stable. The conventional ballast system is operated manually by human operator. In this paper, an automatic control for ballast system for catamaran boat is proposed. The scheme of the ballast system is designed and modeled mathematically. The controller used in this paper is PID controller which the parameters are determined based on the mathematical model of the ballast system and using Ziegler-Nichols method. The simulation results shows that the proposed system have a good results in the accuracy and speed response of the ballast system to stabilize the ship.

Design HMI (Human Machine Interface) for Process Control System of Main Diesel Engine Fuel System

Controlling and monitoring of ship fuel treatment system is based on the needs of safety and business. Therefore, ship automatic fuel system is a support system recommended by ship classification society, engine manufacture, and shipping company. The new system may give highly efficiency operation and supervision. In this research, we developed marine diesel fuel system interface to monitor how the systems work. Main diesel engine fuel system consist of transfer system, separation system, feed system, and circulation system. The aim of this research is to control and display the shipboard fuel system. All valves, pumps, and separator units were controlled by programmable logic controller using tank level switches as input signal. We have tested this automation system with a computer simulations. As an initial step, valves, pumps, and separator units are successfully controlled and displayed. Based on program simulation, the operational leading time of settling tank and day tank are one hour and 9,8 hours, respectively. It is mean both of one settling tank or day tank are ready before the another tank empty. This system also have detection ability due to system failure.

Automatic Stacking Crane Prototype using Microcontroller Arduino Mega 2560

The port is one of the supporting infrastructures for sea-transportation carrying goods and passengers. The function of port is important in supporting the transportation system to develop economic, social, and eduaction with sea-trading as booster. Crane is device which use to lift or move heavy loads and commonly was used in ports for container loading - unloading process. This research will create automatic stacking crane prototype with an Arduino Mega 2560 as controller. There is a lack of this design is the incoming voltage to the motor sourced from this microcontroller module is 5 V. In hence, the spindle motor is not optimal. In addition, there are still many input response procedure was not appropriate.
