    Opis:
    The paper describes the problem of crude oil transfer in a port oil terminal and includes the safety analysis of this operation and analysis of potential causes and possible scenarios of oil spill events in a port terminal. The operation process of crude oil transfer is described and its statistical identification is given. The reliability and availability analysis of the system of crude oil transfer in a port terminal is performed. Moreover, analysis of crude oil transfer process taking into account the human factor is provided. The Fault Tree Analysis and sensitivity analysis for oil spill event in a port terminal is proposed to identify and analyse potential causes and possible scenarios of oil spill. Introducing methods for the prevention of oil spills, special attention is paid to safety procedures during liquid cargo transfer. Technical solutions used in oil terminals are described and recommendation regarding the Emergency Shutdown System are given. Additionally, associated safety systems, such as surge relief system, are described. Emphasizing the role of human factor in the process of crude oil transfer and its safety, trainings on the Liquid Cargo Handling Simulator are proposed to improve skills and knowledge of personnel on board and ashore.

    Opis:
    The paper discusses cases in which a refusal by an energy enterprise to connect other enterprises to the network is treated as a prohibited abuse of the enterprise’s dominant position and, equally, will represent behavior prohibited by art. 12 of the Treaty on the Functioning of the European Union and by art. 9 par. 2 item 2 of the Competition and Consumer Protection Law as well as legal consequences of such refusal. It is important to pinpoint such cases since the EU sectoral regulation does not provide for obligating any undertakings which manage and operate oil pipelines to enter into contracts with other undertakings such as contracts on connecting into their network or contracts on providing crude oil transfer services. Conditions for accessing oil pipelines and selling their transfer capacities are determined by the owners of the networks: private oil companies in the countries across which the pipelines are routed. These conditions are not governed by the EU law. Furthermore, the very obligation of connecting other entities to own network by energy undertakings operating in the oil transfer sector in Poland will only arise from generally applicable provisions of the Polish competition law.

    Opis:
    Significant amounts of crude oil transported from offshore fields to the refineries using tankers or pipelines, demand increased control of seawater pollution. Tanker accidents resulting in oil spills drive much attention, as they influence local marine life and coastal industry. However, the most significant annual amount of crude oil enters the sea in the form of oilin- water emulsion as a result of standard tanker operations, offshore oil extraction and daily work of refineries. Many branches of science are challenged to provide new methods for oil detection, less expensive, more sensitive and more accurate. Remote satellite or airborne detection of large oil spills is possible using joint techniques as microwave radars, ultraviolet laser fluorosensors and infrared radars. Some methods are capable to deal with oil streaks detection and estimation of oil thickness. Although there is currently, no method to detect small concentration of oil droplets dispersed in seawater. Oil droplets become additional absorbents and attenuators in water body. They significantly change seawater inherent optical properties, which imply the change of apparent optical properties, detectable using remote sensing techniques. To enable remote optical detection of oil-in-water emulsion, a study of optical properties of two types of crude oil was conducted. Radiative transfer theory was applied to quantify the contribution of oil emulsion to remote sensing reflectance (Rrs). Spectra of Rrs from in situ measurements in Baltic Sea were compared to Rrs spectra of seawater polluted by 1 ppm of crude oil emulsion, collected using radiative transfer simulation. The light crude oil caused a 9-10% increase of Rrs while the heavy one reduced Rrs up to 30% (model accuracy stayed within 5% for considered spectral range). Results are discussed concerning their application to shipboard and offshore oil content detection.

    Opis:
    Development of industry and trade in the last few decades caused a huge increase in the pollution of the world's oceans. Substantial contributors to marine pollution come with the rivers from land-based sources including the by products of industry, run-off from agriculture activities such as biocides as well as effluents from urban areas. Moreover, a significant amount of marine pollution is caused by shipping and maritime activities. The operation of ship plants gives a real possibility for engine oils and fuels to reach the marine environment. Discharge waters contain a certain amount of petroleum derivatives in the form of dispersed droplets (oil-in-water emulsion). The presence of oil emulsion cause measurable changes in the optical properties of seawater. It is conceptually possible to detect these changes using a standard radiance or irradiance reflectance meter. Hence, a set of radiative transfer simulation has been carried out. This paper presents a computed photon trace simulation based on the Monte Carlo code, applied to the marine environment. The results are presented as reflectance spectra for the models of Baltic Sea and ocean water both pure and polluted by oil emulsion. It is shown that even small amounts of petroleum pollution raise the values of irradiance reflectance and cause a spectral shift by certain conditions. A possibility for remote evaluation of oil pollution is discussed as well as the perspective for improving the interpretation of shipboard and offshore light field analyses.

    Opis:
    German chamomile (Matricaria recutita (L.) Rauschert) belongs to the plants with a high tolerance to toxic elements. The ability of chamomile to accumulate risk elements was tested in a pot experiment in which four soils contaminated by different levels of arsenic (As), cadmium (Cd), lead (Pb), and zinc (Zn), differing in their physicochemical parameters, were used. The element mobility in the soils was affected predominantly by the cation exchange capacity (CEC) of the soils. Whereas As, Pb, and Zn were retained in roots, Cd showed good ability to translocate to the shoots, including anthodia, even in extremely Cd-contaminated soil without symptoms of phytotoxicity. The bioaccumulation factor for Cd calculated as the ratio of element content in the plant and the soil was the highest among the investigated elements. Between 5.5 and 35% of the total Cd was released to infusion, and its extractability decreased with increasing Cd content in anthodia. The essential oil composition suggested an alteration of the abundance of the individual compounds. However, no detectable contents of risk elements were found in the oil. Chamomile can be recommended as a suitable alternative crop for risk element-contaminated soils tested within this experiment, but only for production of essential oil.

    Opis:
    Modern cooling systems for large ships are quite complex. As a rule, such systems are common (combined) for the main and auxiliaries engines. With the auxiliary engines running constantly, even when parked, this system design allows to keep it warm and ready for a quick start of the main engines at any time. Currently, various schemes of such systems are used, including those that are irrational from our point of view. At the same time, there are systems whose schemes are quite consistent with our idea of the rational forms of such structures. It is important to note, and it is saying about it in an article, that such schemes may have a number of significant differences, but at the same time they will comply with the rationality principle if certain rules for the formation of such systems are followed. These schemes will have close compactness. It is also important that there is the possibility of further improvement of such schemes based on certain rules. This improvement is possible due to the introduction of additional heat dissipaters and the organization of appropriate chains of heat sources and heat dissipaters. The article discusses various options for rational schemes of the cooling system for the same ship power plant, as well as the possibility of further improvement of this scheme. It is shown that an increase in the number of coolants of the internal circuit coolant from one to three can reduce the total mass of the heat exchanger cores by 18 %.

    Opis:
    The scheme of the cooling system is considered, which can be the basis for creating the most efficient cooling systems for IC engines of any purpose. It is assumed that the use of any other scheme is devoid of a rational basis. The scheme consists of two connected circulation circuits, in one of which the coolant flow rate is an order of magnitude less than in the second. The engine is included in a circuit with increased coolant flow. All heat exchangers are in the second circuit. Rules for the formation of such systems are formulated. The basis of the method for calculating such systems is considered. It is indicated that the flow rate through each heat exchanger must be determined by calculation to ensure the maximum efficiency of the cooling system. The considered scheme allows to provide the maximum possible depth of charge air cooling, if its temperature is not specified, or to ensure the minimum cost and compactness of the cooling system, if this temperature is known. The scheme allows regulating the temperatures of the cooling fluids of the system with all kinds of changes in the engine operating conditions and the ambient temperature.

    Opis:
    Zbadano wpływ temperatury na zjawisko przenikania olejków eterycznych, pomarańczowego i miętowego, do komórek drożdży piekarskich. Olejki mieszano z zawiesiną wodną świeżych drożdży i wytrząsano w temp. 25, 40, 50 i 70°C w różnym czasie. Po odwirowaniu i przemyciu osadu komórkowego wodą destylowaną preparat suszono metodą liofilizacji. Ilość zakapsułkowanego olejku oznaczano za pomocą chromatografii gazowej po uwodnieniu drożdży i ekstrakcji olejku etanolem. Hydrofobowe olejki eteryczne przenikały do komórek na zasadzie biernej dyfuzji w błonie komórkowej i pozostawały w komórkach po ich wysuszeniu. Szybkość dyfuzji olejków do komórek wzrastała ze wzrostem temperatury i była większa w przypadku olejku miętowego. Maksymalna zawartość olejku pomarańczowego w suchych komórkach drożdży wynosiła 24% s.s. natomiast olejku miętowego 43% s.s. i nie zależała od temperatury procesu kapsułkowania.
    The influence of temperature on the permeation of orange peel and peppermint essential oils into baker's yeast cells was investigated. The oils were mixed by agitation with an aqueous suspension of yeast cells at four temperatures (25°, 40°, 50°, and 70°C). After centrifuging, the yeast cells were washed with distilled water and freeze dried. The oil content in the cells was analysed by the gas chromatography after the water/ethanol extraction procedure. The oils, owing to their hydrophobic nature, passively diffused across the cell membrane and remained in the cells after having been freeze-dried. The rate of their diffusion into yeast cells increased along with the growing process temperature; it was significantly higher for the peppermint than for the orange peel oil. The maximum oil content in the freeze-dried cells was: as for the orange peel: 24% of total solids, and as for the peppermint oil: 43% of total solids; it did not depend on the process temperature.

    Opis:
    The paper presents a comparison of tribological properties for two generations of sliding contacts, i.e. TG15/ Anodic Hard Coating and PASL/AlMC in oil-free piston compressors designed for ecological transport. In the first contact, the piston ring material is Teflon-graphite TG15 (PTFE+15% graphite), and in the other, an acetal-based (PA) sliding composite (PASL) with additional substances acting as solid lubricants (SL), i.e. PTFE, graphite and carbon fibres. Rings made of plastics slide under conditions of technically dry friction against a cylinder liner’s surface made of aluminium alloy and reinforced by an electrolytic oxide coating (AHC) in the case of the first contact and with a cylinder liner surface made of alloy reinforced by the addition of Al2O3 fibres (AlMC composite) in the latter contact. During friction, the wear debris of the filler form a sliding film (transfer film) on the cylinder liner’s surface, which results in a friction coefficient from 0.12 to 0.1 without the use of oil or greases.
    W artykule opisano tribologiczne właściwości tribologiczne dwóch generacji skojarzeń ślizgowych, tj. TG15/ anodowa powłoka tlenkowa oraz PASL/AlMC stosowanych w bezolejowych sprężarkach powietrza przeznaczonych do ekologicznego transportu. W pierwszym skojarzeniu materiałem pierścienia tłokowego jest tarfleno-grafit TG15 (PTFE+15% grafitu), a w drugim ślizgowy kompozyt z osnową acetalową (PASL) z dodatkiem substancji pełniących rolę smaru stałego (SL), tj. PTFE, grafit i włókna węgłowe. Pierścienie wykonane z tworzywa sztucznego współpracują, w warunkach tarcia technicznie suchego, z gładzią tulei cylindrowej wykonanej ze stopu aluminium umacnianego anodową powloką tlenkową (AHC) w pierwszym skojarzeniu oraz z gładzią tulei wykonanej ze stopu aluminium umacnianego przez dodanie włókien Al2O3 (kompozyt AlMC) w drugim skojarzeniu. Podczas tarcia produkty zużycia napełniaczy tworzą na gładzi tulei cylindrowej film ślizgowy (film transferowy), co skutkuje współczynnikiem tarcia 0.12 do 0.1 bez użycia olejów lub smarów.

    Opis:
    One of the major activities during Ship to Ship (STS) transfer operation at sea is to safe approach the Ship to be Lightered (SBL) which moves on a constant heading with slow speed or drifting. In the paper described the manoeuvring problem for approaching during emergency STS transfer operation with oil spill. The approach manoeuvre is considered as a sequence of navigation manoeuvres in specific navigational environment with environmental and operational constraints as well as ship dynamic performance. Additional constraints results from STS transfer operation guide and navigation practise.
