The Support of Underwater Works with the Use of Remotely Operated Vehicles On the Example of Works Conducted On the Wreck of the Fishing Boat WŁA-127

Abstract

The article demonstrates use of underwater remotely operated vehicles during an underwater visual inspection of a sunken vessel. The presented tasks were carried out in the course of underwater works performed from a Polish navy rescue vessel on the fishing boat WŁA-127. The discussed examples include a visual inspection of the sunken vessel and the support offered to Polish Navy rescue divers as they carried out underwater works.

Will an underwater robot ever replace the diver? A rather poor progress or a great success?

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.

Breathing Air Purification for Hyperbaric Purposes, Part II

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.

The Analysis of Drive Systems in Unmanned Underwater Vehicles Towards Identifying the Method of Drive Transmission

Abstract

This is the first part of the material concerned with the analysis of drive systems in remotely controlled unmanned underwater vehicles. The paper discusses the problem of classification of UUVs, mainly remotely controlled, with an indication of four different approaches to this issue. Moreover, the article discusses the nomenclature used in relation to various components of the discussed drive systems and thrusters, as well as indicates the functionality of such systems along with the advantages and disadvantages of the analysed design solutions. The method of analysis of drive systems, its methodology and the results will be the subject of a subsequent publication of the authors.

Analysis of the Breathing Air Production Process for Hyperbaric Purposes

Abstract

The quality of breathing air plays a key role in the safety of divers and hyperbaric facilities. Paradoxically, the change of regulations concerning quality requirements for breathing mixes has imposed the need for verification of the technical and laboratory bases used in their production and control. This article presents the results of research related to the rationalisation of the process of production and supply of breathing air for the purposes of hyperbaric oxygenation. The work was carried out using the SixSigma method.
