We consider a terminal operator, who provides his logistics services of container handling at multiple terminals within the same port. In this setting, the well-known berth allocation problem can no longer be considered per terminal for two main reasons: i) vessel calls should be spread over the various terminals to avoid peaks and troughs in quay crane utilizations, ii) an allocation of two co...

This work focuses on grid-forming (GFM) control of Interconnecting Power Converters (IPCs) that are used to interconnect multiple HVAC and HVDC subgrids form a grid grids. We introduce the concept dual-port GFM leverages ability Modular Multilevel (MMCs) simultaneously its AC DC terminal voltage present two MMC controls. provide analytical results high-fidelity simulations demonstrate (i) is mo...

The Cubi9000 family includes a range of products from the 3D graphics terminal up to the 3D graphics workstation. The Cubi9000 when configured as a 3D graphics terminal connects to a host computer via a parallel interface from Digital Equipment Corporation. The Cubi9000 configured as workstation includes a UNIX2 based mini-computer with a 32 bit microprocessor, mass memory, device handlers (mou...

Many container terminals all over the world strive to be mega-hub port through improving efficiency of terminal operation with high technology. Not only operating equipments in container terminal, but also container terminal gates are introducing state-of-the-art technologies in order to develop an effective gate system. This study focuses on an automation of identification task at gate. We dev...

This study compares ripple port, stacked switched capacitor, and capacitive energy storage architectures for active power decoupling, comparing the number of components, performance, density, DC-link capacitor reduction, efficiency, frequency operation to highlight their main benefits drawbacks single-phase grid-connected applications. The overview reveals equivalent effective density without e...

Tight cooperative control of mobile entities and resources is essential to enhance the efficiency and effectiveness of terminal operation. The paper aims at developing an integrated simulation model which integrates the traffic flow control of internal tractors and the berth operation of a container terminal for evaluation of control policies adopted. Terminal operation is modeled as a discrete...

Ports strive to maximize their revenues through being sufficiently nautically accessible for sea-going vessels while minimizing dredging efforts, among many other objectives. These two objectives form an interesting trade-off as they are both dependent on the chosen maintained bed level. Due system complexities, design of levels is typically optimized using individual vessels, thereby neglectin...

Container handling problems at the container terminals are NP-hard problems. In this paper, we propose a new handling operation’s design and simulation of empty containers, taking into account the interrelated activities at the container terminal. This simulation have been built using a doubled trailer. It moves containers from quayside to yard side or the opposite depending on the flow in cont...

Abstract Port governance structures are a vital factor impacting port investments, efficiencies, effectiveness and productivity. An important determining is the management whether it centralized under national government as State-Owned Enterprise (SOE), decentralized to municipal level, or alternatively privatized. Reforms in indicate that ports either subscribe public service port, tool landlo...
