The development of new technologies, the use and transport of LNG increases the number of investments that may mutually affect their safety on account of a domino effect. It means that a breakdown caused by one of the business entities may contribute to the escalation of a problem through thermal energy emission in another entity. The energy absorbed in an adjacent technological process line may cause irreparable damage despite the security measures employed. When planning an investment of a pioneering nature, one ought to consider not only the modern technologies used in a newly designed installation, but one must also pay attention to the direct neighbourhood of other industrial plants and the planned infrastructure, e.g. for gas transport or transhipment. Such a synergistic approach guarantees the safety of undertaken activities and ensures a stable, breakdown-free operation of all the business entities located in a given area. This paper discusses the issue of mutual influence exerted by two independent entities located within a small distance of one another, i.e. salt processing plant and a vessel transporting an LNG mixture. The authors considered a situation in which a breakdown occurs in an industrial plant and in which the released energy causes damage to a tank shell of an LNG carrying vessel on an inland fairway. In the examined situation the types of risks arising from LNG tank shell damage on-board an inland vessel were defined and the dimensions of the resulting danger zones were determined in a function of concentration of individual LNG components as well as the pressure and temperature generated inside the tank. The shape of the tank was also taken into consideration, since it affects fractioning in the course of the release of the substance accumulated in it. The analysis was conducted on the basis of DNV Phast 7.11 software.

Creating the buffer zones is a function intended to designate an area in particular, of a constant distance around the spatial objects. The aim of the study was to create maps as thematic layers, which served to identify areas of existing and potential contamination of surface water and other environmental elements. Among others, it made possible to localize the areas potentially affected by the surface water pollution due to transport; localize the areas potentially affected by the surface water pollution due to the discharge of sewage from human settlements; localize the zones with mitigated impact of communication emissions due to the natural protection of forests taking the form of so-called geochemical barriers. The spatial analyzes allowed to generate model-zones of the existing and potential threat of water pollution in the Narew river catchment. Designated danger zones can be verified by studies as well as they can be very helpful in determining the monitoring network and for water quality modeling process.

W artykule omówiono wyniki wstępnych analiz podobnych prac prowadzonych (m.in. przez ITWL) w ramach zmodernizowanego śmigłowca W-3PL „Głuszec”. Śmigłowiec W-3PL odpowiada swym wyposażeniem najnowszym śmigłowcom wielozadaniowym (INS/GPS, FADEC, „glass cockpit”, dostosowanie do NVG, głowica obserwacyjna, komputer pokładowy, sterowany podkadłubowy karabin WKMB). Wszystkie te systemy zostały zintegrowane w jeden makrosystem. Jednym z podstawowych pojawił się problem sposobu pozyskiwania danych z dotychczas eksploatowanych systemów ochronyi obrony własnej na pokładzie śmigłowca oraz ich przetwarzania do wersji cyfrowej i zobrazowania nahełmowego (min. zagrożenia z uwzględnieniem stref niebezpiecznych dla statku powietrznego).

What has been presented in the paper is discussion on results of pre-analyses of similar works carried out by various organizations, including ITWL, under the W-3PL ‘GŁUSZEC’ (‘Wood Grouse’) helicopter upgrade project. The W-3PL helicopter’s equipment corresponds with that found on the most recent multi-role helicopters and comprises, among other items, the INS/GPS; FADEC; glass cockpit; the NVG compatibility; the surveillance turret; the modular computer; the HMD-controlled, under-nose mounted WKM machine gun. All these systems have been integrated into one macrosystem. Acquisition of data from the hitherto operated airborne self-protection and self-defence system of the helicopter and how to digitize and display it (i.e. threats to the aircraft, with danger zones included) on the helmet-mounted display system are now the most essential problems.
