Use of the ship maneuvering simulator (SMS) is at the core of pilot trainees education and training, so it is desirable to have an evaluation method that can be completed shortly after each berthing training session. There are basically two methods of docking maneuvering that pilot trainees learn: one in which the ship enters from outside the port and is...

This chapter introduces the use of hybrid intelligent agents in a vessel berthing application. Vessel berthing in container terminals is regarded as a very complex, dynamic application, which requires autonomous decision-making capabilities to improve the productivity of the berths. In this chapter, the dynamic nature of the container vessel berthing system has been simulated with reinforcement...

Piles and diaphragm wall supported berthing structure on marine soils are loaded laterally from horizontal soil movements generated by dredging. The literature on the adequacy of the finite element method modeling of berthing structure to analyse their behaviour during dredging and under earthquake condition is limited. This paper describes the finite element approach for analysing the lateral ...

Among ship maneuvers, berthing/unberthing maneuvers are one of the most challenging and stressful phases for captains. Concerning burden reduction on operators preventing accidents, several researches have been conducted trajectory planning to automate berthing/unberthing. However, few studies aimed at assisting captains in The be presented captain should a maneuver that reproduces human captai...

Using dead zones of rivers for berthing purpose may involve some problems of which the most serious are sedimentation and silting. These processes depend on water flow pattern in these zones. In this paper, a two dimensional depth averaged model is explained for flow modeling in river dead zones. Governing equations of fluid flow are discretised using the “Control Volume” method and...

Singapore has one of the busiest ports in the world. Ship berthing is one of the problems faced by the planners at the port. In this paper , we study the ship berthing problem. We first provide the problem formulation and study the complexity of the problem with different restrictions. In general, the ship berthing problem is NP-complete, although, some of its variants may be solved quickly. Wh...

Over the years, the demand for maritime transportation has rapidly increased [1], [2]. This usually leads to an increasing in competition among different ports in providing efficient services. Port managers face significant challenges in efficiently utilizing the given resources to provide a cost-effective service [1]. Among many optimization and decision making problems in the port management ...

Genetic Algorithm which is based on the Darwinian principle of natural selection has been successfully applied to Berth allocation problem (BAP), which can decide the ships’ berthing position and berthing time at a container terminal. Considering the service priority, handing time deciding variables, safety clearance, as well as the berths’ physical conditions, a dynamic berth allocation with d...
