碩士 / 長榮大學 / 經營管理研究所 / 94 / In order to keep the surface of port’s inner water calm and stable, the port entrance normally is designed and constructed as narrow as possible. This leads to the outcomes that channel is not wide enough to allow ships to traverse in two-way manner. This is the reason why one-way channel are commonly seen in most ports over the world. One-way traverse highly restricts the accessibility of channel. The accessibility restriction is not a matter of channel itself, but it influences the performance of whole port. Projects in relation with facility planning or operations analysis should not ignore the effects coming from one-way channel. However, the impacts resulting from one-way channel has not earned attention so far.
This study construct a simulation program to simulate the operations of one-way channel of port of Kaohsiung. The simulation program arm to analyze the effects, resulting from accessibility restriction of one-way channel, on the waiting time for berthing. Factors that influence ships’ traverse in and out of port of Kaohsiung such as demand pattern of berthing, berth types, quantity, and specifications, tugboat quantity and specifications, and regulatory mechanism of channel operations are taken into consideration.
Ship waiting time for entry into a port is a foundamental index of port planning. If take it as the criterion to evaluate with vs. without taking consideration of channel and tug operations. For the study target, the 2nd zone of port of Kaohsiung 2005, the without case renders lower ship waiting time then the with case by 1.2 hours. The amount of under-estimate of ship waiting time is getting larger as the number of ship increases. When the number of ships becomes 1.5 times of the base year, the under-estimate of ship waiting time increases up to 4.36 hours.
The simulation program also is capable of analyzing the operational consequence resulting from different composition of tugboats by size and quantity. It is a useful tool for the decision of the install of tugboats.
