Abstract:

Wired electric equipment overheating monitoring system has some limitations in electric propulsion ships. This paper designs an electrical equipment overheat monitoring system based on Wireless Sensor Network (WSN) to monitor the overheat of electrical equipment. To verify the performance of the whole system, we design the hardware and the software of sensor nodes and coordinators. In order to extend the lifetime of sensor node effectively, the system adopts the dynamic sleep and controllable transmit power method. The results show that this system achieves the accurate measurement of electric

The feasibility and potential benefits of using Integrated Electric Plants in future Great Lakes self-unloaders are evaluated. Integrated Electric Plants, the all-electric ships, utilize electrical propulsion motors and central station power generation that powers all propulsion, thruster, self-unloading equipment, and other ship service needs. Integrated Electric Plants have become the plant of choice in many recent naval vessels, cruise ships, high technology cargo vessels, and special purpose vessels, such as offshore supply and service vessels and icebreakers.

Owing to more and more sensitive loads installed in modern ships, ship owners and builders have been faced with rising numbers of complaints about the quality of power. However, the existing power monitoring facilities installed onboard for recording deviations of power parameters is only over steady-state conditions due to limited capacity of measurement equipment and ignores short-duration phenomena. To understand the true supply quality in ships, a power quality (PQ) monitoring technique is employed in this paper. The PQ parameters including short-duration and long-duration voltage and freq

Abstract:

The need of electricity in every ship are very diverse. Power plants for using diesel as an engine can also come from sunlight as an alternative source of electrical energy. The measurement of solar energy in Indonesia is 4.8 kWh /m2. This renewable energy is in suitable for the Indonesian topography. Thus, the energy from the sunlight around the equator is so abundant that its availability is always available throughout the year, except when it rains. Utilization of solar energy can be used as a substitute for conventional energy which is starting to be limited and the price is quite expensiv

Mechanical resonance and high-frequency vibration caused by the external environment will not only affect the performance of vehicles, ships and machinery, but also cause serious harm to human health. In order to pursue higher ride comfort and reduce the adverse effects on the operator when operating the equipment, the shock absorbers are widely used in aircraft, vehicles and other vehicles or precision machinery. The automatic control of the hysteresis power system of the shock absorber is one of the key tasks in the design and application of the shock absorber. With the development and matur

Unmanned autonomous transport vessels (MASS) are the future of maritime transport. The most important task in the design and construction of unmanned ships is to develop algorithms and a computer program for autonomous control. In order for such a computer program to properly control the ship (realizing various functions), the ship must be equipped with a computer system as well as measurement sensors and navigation devices, from which the recorded parameters are processed and used for autonomous control of the ship.

The chosen electrical equipment, i.e., the earthing switch has its application in marine switchgear. In this paper, the reduction of dimensions is considered with the purpose of making it more energy efficient in terms of onboard application. This test validates that the earthing switch as an electromechanical device is capable of withstanding electrodynamic forces. Two approaches are applied and compared. Both approaches are based on a simplified three-dimensional (3D) model of the earthing switch. The first approach is analytical: the electrodynamic forces are calculated with the assumption

The main reasons for the bolted joint weakening are dynamic changes in operating current loads and changes in climatic parameters. It is possible to increase the reliability of bolted conductive joints using modern diagnostic methods that allow identifyi
