The inland waterborne transportation is viewed as an economic, safe and environmentally friendly alternative to the congested road network. The traffic capacity are the critical indicator of the inland shipping performance. Actually, interacted under the complicated factors, it is challenging to conduct studies on the capacity in the networks of...

The implementation of the Finnish-Swedish winter navigation system has managed to increase the safe passage of merchant vessels in the Baltic Sea. However, there will always be risk associated with Baltic Sea winter navigation. Based upon IMO’s Formal Safety Assessment; steps zero through two, this report will aim to provide a system description...

Since Automatic Identification Systems (AIS) was widely used in navigation industry, it has not only greatly benefited ship operations to keep encountered vessels visible to each other, but also fosters the relevant researches. Because AIS message contain vessel's identity, position, course, speed and so on, the application of AIS data make it...

This paper provides overview of the currently available theoretical methods and their capabilities in relation to simulations of the maneuvering behavior of displacement type of ships in a seaway. It has been considered that the ships are engaged in typical type of maneuvers such are for example Zig-Zag and Turning maneuvers according to IMO...

This is the recent review of author’s researches since last workshop held in Shanghai. The algorithm of automatic collision avoidance system and other functions used in Marine Traffic Simulation System (MTSS) and Imazu problem with sample simulation result using MTSS were introduced in the previous workshop. In this paper some results of free...

In this paper, a numerical study on the behaviours of a ship passing through a lock under the influence of a berthed ship is carried out. The viscous flow and hydrodynamic forces are calculated by applying an unsteady RANS code with a RNG k-å turbulence model. UDF is compiled to define the ship motion. The numerical results are obtained and...

When a ship sails with a certain speed, there is always a return current along and under the ship. The return current induces a water level depression around the ship. When the ship travels along a bank, the flow field around the ship is asymmetrical. Additional bank effects will be induced. A reliable estimation of all these effects and the...

This paper describes a microscopic nautical traffic simulation model based on multi-agent system. The ship traffic is produced from the behavior of autonomous agents that represent ships. Especially, we look at the behaviors for collision avoidance in different encountering situations with different local environmental conditions. The behavior...

The access policy to ports for deep-drafted ships making use of channels which are subject to waves, tides, currents, wind and other complicating factors can be based on either deterministic or probabilistic principles. ProToel is a calculation tool for determining tidal windows for marginal vessels arriving at or departing from ports located at...

Van Westrenen, F. (author)
This paper presents a design for a cognitive navigator model based on Rasmussen’s model of skill- rule- and knowledge-based behaviour. The basic assumption is that navigators do not attempt to minimise the deviation from a track-line but attempt to realise efficiency and safety by balancing prediction and mental workload. The resulting model is...

According to the COLREGs, every Officer On Watch (OOW) shall at all times maintain a proper look-out. Among all the available means of look-out, sight is the most basic and commonly used one. OOWs always need to make a full appraisal of the situation and of the risk of collision by sight, including estimating the range and bearing. Unlike the...

Maritime traffic safety and capacity raise enormous attention nowadays, especially in ports and inland waterways with high traffic density and restricted waterway geometry. However, a limited number of factors is considered in existing maritime models. Especially influences of external factors (wind, visibility and current), vessel encounters...
