Assessing the Frequency and Material Consequences of Collisions with Vessels Lying at an Anchorage in Line with IALA iWrap MkII

This paper proposes a collision model for ships underway and temporary objects as an extension to state-of-the-art maritime risk assessment like IALA iWrap MkII. It gives a brief review of frequency modeling and consequence calculation theory as well as its applications, before it analogously derives a model to assess the risk of anchorage areas. Subsequently, its benefit is demonstrated by an example scenario.

Dispatching Strategies of Drayage Trucks at Seaport Container Terminals with Truck Appointment System

Implementing a truck appointment system at container terminals is a successful method to smoothen peaks in truck arrivals and thereby reduce truck waiting times and congestion in the port area. In spite of extensive literature on its impact on container terminal productivity, other stakeholders in the port drayage network have been studied only occasionally. This paper aims to analyze different strategies of time window selection for port drayage companies considering different company sizes and competitor’ strategies. The analysis is done by means of a discrete event simulation model. The results show that an early booking of appointments at container terminals is beneficial for the success rate of trucking companies. Furthermore, it is highlighted that the truck turn time of small-sized companies in this network is higher than the one of large-sized companies.

Simulation-Based Analysis of Dispatching Methods on Seaport Container Terminals

Efficient dispatching of vehicles and transport orders between the quayside and the yard of container terminals is an important challenge for terminal operators. Despite the large amount of literature in this field, there is no systematic approach investigating the effects of terminal characteristics on the performance of different dispatching methods. This simulation study aims to close that research gap for the case of different dynamic dispatching methods.
