Abstract

The article defines a system of sea waterways and discusses general principles of modeling such systems. Conditions for safe operation of marine waterway systems are specified. The author's model of waterway parameter optimization herein presented was used in designing a system of approach channels leading to the outer port in Świnoujście, the LNG terminal.

Abstract

The article deals with the subject matter related to the development of underwater works technologies. Nearly 15 years ago one of the authors of this study published a material in the monthly magazine of “Podwodny Świat” (The Underwater World) entitled “The Future of Underwater Technologies – the diver or the robot?” where he noted that the time of great changes in technologies aimed at researching the depths and conducting works under water has arrived. This new era mainly consists in the fact that on an increasing number of occasions the diver is replaced by an underwater robot. The presented material constitutes an attempt to provide an answer to the question whether the then posed thesis is still valid. In the article the authors discuss issues concerned with the development of techniques and technologies applied in the conquest of depths that leads them to the conclusion that the previously observed tendency of a double-tracked development of underwater technologies is gaining in strength, which causes that the works and exploration of bodies of water at great depths will be possible only with the use of unmanned techniques.

Abstract

The material presents an analysis of the impact that the parameters of air hyperbaric exposure have on the time remaining to the beginning of the first ventilation, as calculated with two mathematical models. The research has been conducted in the form of simulations that take into account standard parameters of exposure. Differences between the analysed models have been indicated, and the influence of the changes of particular input values in the analysed models on the output values has been defined.

Abstract

Determining the efficiency of breathing air purification for hyperbaric purposes with the use of filtration systems is of a crucial importance. However, when the Polish Navy took samples of breathing air from their own filtration plant for quality purposes, these were found to not meet the required standard. The identification of this problem imposed the need to undertake actions aimed at the elimination of the identified disruptions in the process of breathing air production, with the objective of assuring its proper quality. This study presents the results of the initial tests on the air supply sources utilised by the Polish Navy, which were carried out for the purpose of setting a proper direction of future works and implementing corrective measures in order to optimise the breathing air production process. The obtained test results will be used in a subsequent publication devoted to the assessment of the level of efficiency of air purification with the use of a multifaceted approach consisting in the utilisation of various types of air supply sources and different configurations of purification systems.

Abstract

This is the first publication from a series of articles devoted to the issues of underwater exploration carried out for litigation purposes. The present paper suggests that an exploration strategy should be defined as: all actions that aim at creating and implementing a plan of exploration, conducted with the application of a defined exploration methodology - here understood to refer to the technical way the task is completed. Such an approach is taken in order to ensure the most adequate involvement of means and resources for the plan’s implementation. Since the choice of strategy affects many aspects that range from the technical to the environmental, this first part focuses on the location of the exploration and the anticipated conditions.
