基于模拟减少集装箱船待港时间的实用方法(英文)

The main challenge for container ports is the planning required for berthing container ships while docked in port.Growth of containerization is creating problems for ports and container terminals as they reach their capacity limits of various resources which increasingly leads to traffic and port congestion.Good planning and management of container terminal operations reduces waiting time for liner ships.Reducing the waiting time improves the terminal’s productivity and decreases the port difficulties.Two important keys to reducing waiting time with berth allocation are determining suitable access channel depths and increasing the number of berths which in this paper are studied and analyzed as practical solutions.Simulation based analysis is the only way to understand how various resources interact with each other and how they are affected in the berthing time of ships.We used the Enterprise Dynamics software to produce simulation models due to the complexity and nature of the problems.We further present case study for berth allocation simulation of the biggest container terminal in Iran and the optimum access channel depth and the number of berths are obtained from simulation results.The results show a significant reduction in the waiting time for container ships and can be useful for major functions in operations and development of container ship terminals.     

集装箱货运仿真模型在珠三角港港口投资方案评估(英文)

In the Pearl River Delta (PRD), there is severe competition between container ports, particularly those in Hong Kong, Shenzhen, and Guangzhou, for collecting international maritime container cargo. In addition, the second phase of the Nansha terminal in Guangzhou’s port and the first phase of the Da Chang Bay container terminal in Shenzhen opened last year. Under these circumstances, there is an increasing need to quantitatively measure the impact these infrastructure investments have on regional cargo flows. The analysis should include the effects of container terminal construction, berth deepening, and access road construction. The authors have been developing a model for international cargo simulation (MICS) which can simulate the movement of cargo. The volume of origin-destination (OD) container cargo in the East Asian region was used as an input, in order to evaluate the effects of international freight transportation policies. This paper focuses on the PRD area and, by incorporating a more detailed network, evaluates the impact of several infrastructure investment projects on freight movement.

Design and implementation of a visual monitoring system to ensure safety in the water surrounding a container vessel

Container vessels navigate among the world's ports,frequently passing through narrow and congested waters.Due to the many layers of containers on a container vessel's decks,it is difficult for the crew to be aware of all fishing vessels and other obstacles in a container vessel's radar observation blind zone.This greatly increases the risk of collisions and other accidents.Given such great challenges to safe navigation and safety management with container vessels,their security risks are severe.An effective visual monitoring system can improve the safety of the water area surrounding container vessel by eliminating a vessel's observation blind zone,providing an effective safety measure for vessels navigating fishing zones and other troublesome areas.The system has other functions,such as accident recording,ship security,and monitoring of loading and unloading operations,thus ensuring the ship operates safely.Six months'trial operation showed that the system facilitates safe navigation of container vessels.     

Sydney Port Company——The bridgehead of China-Australia trade

Sydney is the largest city and important container import center in Australia.Sydney serves as the first stop for most of the trade goods coming from China. Therefore, Sydney Port Company has become the important bridgehead of China-Australia trade. The reason is that Sydney not only exists as one of the big markets but also locates in the center of the region, connecting with large central cities through highways and railways. Cargo can be transported     

A study on Implementation of Automatic Gatehouse System in Container Terminal

As we know,Gatehouse (Gate-In /Gate-Out) business is one of the most important sections in the operation of container terminal(CT).On one hand,Gate-In is the first checkpoint for all export container cargoes to CTs,where we should make clear the related responsibilities of container cargoes between shippers and CTs.On the other hand,Gate-Out is the last checkpoint for all import cargoes from CTs,where the relevant liabilities of container cargoes should be distinguished by CTs and consignees,too.The CT where I work now is in Europe and ourlabor costs are much higher than those in China.In this case,in January,2010,we began to study and designanautomatic gatehouse system(AGS) in order to lower relevant costs by accelerating the passage of containers through Gate-In and Gate-Out and reducing the number of container inspectorsas well.     

A study on Automatic Reefer Monitoring Solutions in Container Terminals

With the fast improvement of the technology of refrigeration in reefer containers (hereinafter referred to as 'reefer' or 'reefers'),the scope of containerizable reefer cargos is expanded continuously in the past years,from the fish that should be frozen at minus 60 degrees Celsius to the flower bulbs at 30 degrees Celsius and from the temperature-sensitive goods whose deviation should be less than 1 degree Celsius to the fresh fruits and vegetables controlled by humidityventilation adjustment system.Being an important node in the logistics chain,the container terminal (hereinafter referred to as ‘CT') should pay more attention to these state-of-the-art techniques and adopt the accordingly suitable technology to optimize its reefer monitoring business in order to provide the highly cost-effective services to ship owners (or their agents) and shippers / consignees (or their brokers).

The development of studying flexible pipe bend reinforced by Kevlar fibers

The flexible pipe bend can not only reduce the structural vibration and fluid noise in pipeline, but also realize the flexible connection of a horizontal line and a vertical line and compensate the displacement of three dimensions produced by the shock or vibration of pipeline in the special situations. Up to now, little attention has been paid to study the flexible pipe bend applied in the pipeline of medium or high pressure, because no appropriate framework materials can be used to reinforce it which must endure the burst pressure higher than 10 MPa. The investigation shows that it is possible to produce the flexible pipe bend of medium or high pressure if such fibers with high performance as Kevlar fibers are used to be its reinforced materials. However, its structural designing theory, manufacturing technology and measuring techniques aren‘t yet perfect and systematic, which leads to the instability of the performance of products. Furthermore, few references about its research can be seen. Therefore, it is necessary to systematically and thoroughly develop the structural designing theory, manufacture technology and measuring techniques of flexible pipe bend.     

Risk zone of wrack hitting marine structure simulated by 2D hydraulic model

The wrack or the ship out of control will drift with flow.One of the most important factors that drive the ship is flow current which moves circularly in tidal area.The wrack from same place always drifts in different ways if the start time is different.So,during the ship drifting period,the drift trace is also determined by both wave and wind forces.The drift direction is limited by water depth which must be deeper than ship draft. These marine structures that can not afford the hit of wrack or will destroy the wrack must be well considered when they are placed near harbor and waterway or other water area with ship running.The risk zone should be consulted according to tide and weather conditions to protect structures and ships in necessary.A method is presented here to simulate the risk zone by 2D numerical hydraulic model with tidal current,wave,wind and water depth considered.This model can be used to built early-warning and protect system for special marine structure.
