Abstract:

Cranes are increasingly used in transportation and construction. increasing demand and faster requirements necessitate better and more efficient controllers to guarantee fast turn-around time and to meet safety requirements. Container cranes are used extensively in ship-to-port and port-to-ship transfer operations. In this work, we will extend the recently developed delayed position feedback controller to container cranes. In contrast with traditional work, which models a crane as a simple pendulum consisting of a hoisting cable and a lumped mass at its end, we have modeled the crane as a four

Abstract:

The seismic behavior of port container cranes has been largely ignored-by owners, operators, engineers, and code officials alike. This is despite their importance to daily port operations, where historical evidence suggests that port operational downtime following a seismic event can have a crippling effect on the affected local, regional, and national economies. Because the replacement time in the event of crane collapse can be a year or more, crane collapse has the potential to be the "critical path" for post-disaster port recovery. Since the 1960's, crane designers allowed and encouraged

Abstract:

Container cranes represent one of the most critical components of ports worldwide. Despite their importance to port operations, the seismic behavior of cranes has been largely ignored. Since the 1960s, industry experts have recommended allowing cranes to uplift, believing that it would limit the amount of seismic loading. However, modern cranes have become larger and more stable, and the industry experts are now questioning the seismic performance of modern jumbo cranes. The main goal of this research was to experimentally investigate the seismic behavior of container cranes from the gener

The work in this thesis starts with the development of a Graphical User Interface to aid the manual control of the experimental crane model and to achieve a better container management system. A structural analysis of the laboratory rig is then carried out. The technique used is to divide the whole structure into two parts: a stationary framework and a moving substructure (including its attachments). The dynamic effect of the moving substructure is represented by four equivalent, time-dependent, contacting forces (or lumped masses), and the dynamic behaviour of the stationary framework, induce

Container traffic in seaports around the world in constantly increasing, with energy costs being a significant part of the total costs. The container terminal (CT) of the Port of Gävle, the largest in the east coast of Sweden, is not an exception to this. With traffic growing annually, a new terminal will be opened in the following years, adding three more ship-to-shore (STS) cranes to the two existing ones, and six electric rubber tyred gantry (eRTG) cranes. Therefore, it is highly important to strengthen energy efficiency measures, reducing the energy consumption and the costs associated wit

We investigate the implementation of nontraditional open-loop and closed-loop control techniques to systems at the micro and macro scales. At the macro level, we consider a quay-side container crane. It is known that the United States relies on ocean transportation for 95% of cargo tonnage that moves in and out of the country. Each year over six million loaded marine containers enter U.S. ports. Current growth predictions indicate that container cargo will quadruple in the next twenty years. To cope with this rapid growth, we develop a novel open-loop input-shaping control technique to mitigat

Modern cranes built for the handling of containers should work efficiently concerning the energy consumption, and should also decrease the time of the handling process by using high trolley velocities. On the other hand these cranes should be able to reach the target positions precisely and without residual vibrations. Especially, the trolley accelerations needed to shorten the operating cycles excite the load as well as the crane structure, leading to vibrations, which should be reduced by suitable control methods.

碩士<br>國立成功大學<br>工業與資訊管理學系<br>107<br>It is possible to reduce the container ship’s docking time by making good use of time to pre-arrange containers when there is no ship stopping by the quay. In order to determine the order of pre-marshalling operations, we built an integer programming model to solve it. Our research is different from current literatures since we expand the scale of the problem from a single bay to multiple bays and add corresponding restrictions to meet the situation where two RMGCs operate simultaneously. However, results showed that we can only solve small-scale problems by

碩士<br>義守大學<br>電機工程學系碩士班<br>98<br>Ship-to-shore container cranes are not only the major equipment of shipment of ocean transportation but also their processes are important to reduce freight time. Container cranes use inverters to control large AC/DC motors to achieve various actions of loading or unloading containers. However large inverters and large AC/DC motors have non-linear load characteristics, those characteristics will produce large amounts of harmonic currents when the equipment works. The harmonic currents produced will propagate through power systems, affect other electrical equipm

碩士<br>國立臺灣海洋大學<br>航運管理學系<br>99<br>Due to the increasing size of modern ships, the demand of the capacity of the yard is increasing. Owing to the limitation of existing yard space, many terminals have equipped with rail mounted gantry crane (RMGC) to stack containers in a close and high manner to increase the capacity of the yard, which tends to result in reshuffles while picking out the containers if they are not appropriately allocated. To reduce unproductive movements and increase the yard operation efficiency, preferred areas allocating problems (PAAP) has become a critical issue for termin

碩士<br>國立東華大學<br>運籌管理研究所<br>99<br>Ocean transportation becomes more important by containerization. Nowadays vessels are built much bigger as throughput of ports increases. Planners need to reduce the berthing time of vessels and improve the operational efficiency of container terminals. Container yard is one of the areas in a container terminal highly affected by the increase in container throughput (Vis and Carlo, 2010). Yard crane is the key equipment in container yard. Good schedules of yard cranes are indispensable to improve the productivity of container terminals. Our thesis consider
