Siport21 presents three papers related to navigation areas design, passing- ships effects and nautical risks in 34th PIANC World Congress

Siport21 has presented three papers in the 34th PIANC World Congress, held in Panama this week. The papers are related to navigation areas design, passing-ships effects and nautical risk assessment. These methodologies are applied in order to optimize infrastructure design and improve safety in navigation.

One of the projects is based on the detailed design of the manoeuvring areas using real-time ship manoeuvring simulators, the most advanced tool to be used in this process. Therefore, precise operation limits, manoeuvring strategies and contingency plans can be elaborated.

For this purpose, a technical committee representing the main stakeholders in the project (Port Authority, Operators, Designers, Maritime Authority, Shipowners, Pilots, Tug Companies, …) is recommended to be created. They participate in common workshops during the design process, in order to check input data and assumptions, survey the simulations, contribute to the discussions and finally validate the simulation results and incorporate their opinions. The detailed design is improved providing a high confidence level among all project participants, in particular Local Pilots.

The methodology to analyse moored ship behaviour due to passing ships effects has been presented in the Congress as well. This methodology was applied to analyse the feasibility of a new terminal from an operational point of view.

The aim of this study is to analyse the effects of passing ships, selected from traffic data in the area, on moored vessels at the new terminal. In view of all the previous results, different alternatives were proposed in order to improve the conditions obtained in the analysis and raise the operation limits. This kind of interferences become more and more frequent and important taking into account traffic volume increase and operation of larger ships. They might generate risky situations, especially in terminals handling dangerous goods.

Finally, the company presented a nautical risk analysis developed for the Danube Bridge Vidin-Calafat, connecting Bulgaria and Romania. The aim of the study is to evaluate the risk of collision of vessels and barges with the bridge piles on a secondary branch of the river and therefore decide on the degree of protection of such structures.
