Opis:
The Genaveh commercial port was placed on the agenda of the Iranian PMO (ports and maritime organization) to consider economic, commercial and residential development in Bushehr province and specifically in Genaveh city. In order to increase the water capacity of the port, it is necessary to build a new harbour basin for exploitation and commercial purposes at a depth of 5 to 6 meters by extending the existing jetties arms in front of the port. This research aims to investigate the harbour basin’s tranquillity for providing vessels with safe berthing. For this purpose, three modules, namely the flow model (FM), spectral wave (SW) and Boussinesq waves model (BW) from the MIKE 21 software package, were utilized. According to the monitoring data, which is provided by the Iranian PMO, the harbour basin’s tranquillity based on the prevailing wave directions was investigated. Based on the diffraction graph in the harbour basin, the results showed that, according to the percentage of permissible diffraction recommended by different valid regulations, there is a need to modify the geometry of the breakwater arms to increase the harbour basin’s tranquillity at the port in the development plan.

Opis:
The paper analyses possible causes of failure of the rotating footbridge over the Ustka port channel. In July, 2015, strange behaviour of this object was observed in the form of excessive vibrations of bridge platform suspension rods, with the accompanying acoustic effects. A preliminary geotechnical analysis has revealed that this destructive effect was caused by the nearby construction works, namely construction of a fishing basin and communication routes in the area close to the bridge, which affected the bridge lashing rod foundation settings. Ground vibrations generated by certain construction activities were likely to have direct impact on decreasing the bearing capacity of these rods and increasing the susceptibility od the piles to extraction. After detecting the above problems in bridge operation, its geodetic monitoring was started. The data recorded during this monitoring, along with the results of force measurements in the rods, have made the basis for a series of numerical simulations, performed in the Finite Element Method (FEM) formalism. The bridge structure was analysed in the conditions defined as the emergency state. Extreme efforts of bridge elements and its dynamic characteristics were examined. A possible source of strange behaviour of the footbridge during its operation which was recognised during these simulations was the coincidence of the global natural frequency of the entire bridge structure with local vibrations of suspension rods, at the frequency approximately equal to 1 Hz. This situation was likely to lead to the appearance of the so-called internal resonance phenomenon. As a final conclusion of the research, recommendations were formulated on possible object oriented corrective actions.

Opis:
In relation to the current development of the sailing, modernization and development of yacht ports and marinas are necessary. The preparations process, stages of the design, analyses and finally construction of yacht ports is time-consuming and laborious. In the article a statistical analysis of selected design parameters was described. In order to carry out the analysis a database was created based on 210 ports from different regions of the world such as: Europe, North America, Australia and South Asia. Google Earth was used to obtain the actual values of the analyzed parameters. Most of achieved results was described in the form of tables or graphs.
W związku z bieżącym rozwojem żeglarstwa, konieczna jest modernizacja oraz rozwój portów jachtowych i marin jachtowych. Proces przygotowania, etapy projektowania, analizy i wreszcie budowa portów jachtowych jest czasochłonna oraz pracochłonna. W artykule opisano statystyczną analizę wybranych parametrów projektowych. W celu przeprowadzenia analizy stworzono bazę danych opartą na 210 portach z różnych regionów świata, np: Europa, Ameryka Północna, Australia i Azja Południowa. Do uzyskania rzeczywistych wartości analizowanych parametrów wykorzystano Google Earth. Większość uzyskanych wyników została opisana w formie tabel lub wykresów.
