    Opis:
    For oil and gas transportation in some places used SPM (Single mooring point) system, this is located in the open sea and very often not so far away from the shore. Differences between the wind loads, waves and current forces can take a place. More complicate conditions can be in case if FSU is still in ballast and more influence has wind and waves as current and in the same time tanker in loaded position is more influenced by the current. Navigational safety ensure in SPM regions requests deep theoretical studies and very clear understanding of forces and moments, which influence on all the system (SPM, FSU, Tanker, tugs), practical implementation of proper equipment and use of correct methods of navigational safety. In this article there is made analysis of possible failures and necessary actions to ensure navigational safety in SPM regions.

    Opis:
    Ro-ro vessels use shipside and shore ramps as roll-on/roll-off loading facilities. Baltic Sea has not tidal effects and water level did not change very much. In same time water level fluctuations in ports areas make difficulties to establish proper access to shore for ro-ro vessels during loading and unloading operations. Flexibility of ro-ro vessel-to-shore links pan is one of the key elements for optimization of ro-ro operations in ports. Feasibility outline of pontoon ramp potential, calculation methods and practical usage is studded and presented further in the article.

    Opis:
    Container traffic grew very fast and many ports have prepared infrastructure and superstructure for the container vessels. During the last decade, many of Eastern Baltic ports container terminals started working with container vessels and in the same time looked for the bigger container vessels with limited possible investments (1). In many ports are very limit space inside the ports and it make additional difficulties increase entry to the ports ships size. Container terminals usually are located in the middle or in the end parts of the ports and find enough space for the ships turning basins raise difficulties. Big container vessels navigational safety must be linked with ports infrastructure, but very often ports are orientated on the old standards and design recommendations, so are trying to keep big safety coefficients regarding water ways depths, widths, and hydrometeorological conditions limitations. Old standards did not include new accuracy navigational equipment such as RTK systems, which are implemented in many ports and increase navigational possibilities and navigational safety. This paper addresses the theoretical approach of the influence of new big container vessels sailing within ports areas, namely ships turning basins, possibilities and navigational safety of the ships, which have big wind surface and good manoeuvrability.
    Intensywny wzrost ruchu kontenerowców narzucił konieczność odpowiedniego przygotowania infrastruktury portowej. W ciągu ostatniej dekady wiele spośród terminali portowych na Bałtyku Wschodnim rozpoczęło współpracę ze statkami kontenerowymi, poszukując równocześnie innych dużych jednostek tego typu z ograniczonymi możliwościami inwestowania (1). W wielu portach powierzchnie ich basenów nie odpowiadają potrzebom kontenerowców, co powoduje trudności przy wejściu. Terminale dla statków kontenerowych zwykle położone są w środku lub na końcu portu i znalezienie tam odpowiedniej powierzchni, by wykonać manewr obrotu stwarza wiele trudności. Bezpieczeństwo nawigacji w przypadku dużych jednostek musi być powiązane z infrastrukturą portową, jednak bardzo często porty pracują w oparciu o stare normy i zalecenia, w związku z czym starają się zachować wysoki współczynnik bezpieczeństwa pod względem głębokości i szerokości dróg wodnych oraz warunków hydrometeorologicznych. Stare standardy nie uwzględniają też nowoczesnych urządzeń, takich jak systemy RTK, służących dokładności nawigacyjnej, które są wprowadzone w wielu portach i zwiększają możliwości i bezpieczeństwo. Artykuł stanowi teoretyczne ujęcie żeglugi nowych kontenerowców w obszarze basenów portowych, omawia bezpieczeństwo i możliwości nawigacyjne statków o dużych gabarytach i dobrej sterowności.

    Opis:
    LNG import terminals are under construction in the Baltic Sea ports Klaipeda and Świnoujście and should start operations in 2014. LNG tankers in Klaipeda port should cross port up to the end of the port. Probability of possible emergency situations with LNG tankers is very low, but in the same time it is necessary to take all possible precaution measures to avoid accidents with LNG tankers in any cases, especially in port areas. “Black out” on the LNG ships is very dangerous in ports areas, because there is very limited channel’s width and other port water areas, and it is necessary to steer vessel in such situations as well. Theoretical calculations of the precaution measures, simulations and practical training of the ship and tugs masters, port pilots and VTS operators should help in such emergency situations. This article is oriented to explain theoretical calculation methods for the LNG tankers steering by tugs in case of “black out” situations, simulations’ results and practical recommendations for the Port Authorities, port pilots, ships’ and tugs’ masters that will be possible to minimize LNG ships’ incidents and accidents probability in port areas.

    Opis:
    Ro-Ro and Ro-Pax ships works on basis of regular schedule and try keep this schedule as accurate as possible. In same time difficulties during Ro-Ro and Ro-Pax ships voyages like bad weather conditions, waiting time to entry in to port, ship's failures and others, sometime request more time as it was planned initially. Ro-Ro and Ro-Pax ships arrivals in to port evaluation is important not only just for the Ro-Ro and Ro-Pax shipping lines planning but as well it is very important for passengers, transport units (trucks) and port terminals. In this Article are analyzed delay times of Ro-Ro and Ro-Pax ships arrival to port on basis of statistical data and used mathematical models for calculation of the arrival time pass.

    Opis:
    While it is true that heavy metals accumulate in soil easily, their removal is difficult. The organic fraction of municipal solid waste can be recycled into compost, although frequent application of biowaste may lead to the accumulation of heavy metals in soil. There is no deep-rooted tradition in Lithuania to make and use various biowaste composts, including the ones produced from municipal waste. The objective of this study has been to compare the accumulation of heavy metals in different parts of oilseed pumpkin fruit depending on the chemical composition of the compost the pumpkin plants had been supplied. The content of heavy metals (HM) was determined in the soil before the plant-growing experiment, and in biowaste composts of different origin. Green waste (GW) and municipal solid waste (MSW) composts were applied to soil as fertiliser. Heavy metal concentrations in the skin, flesh and seeds of the analysed pumpkin fruits did not exceed the maximum permissible concentrations established by the EU norms. Seeds of the investigated pumpkin cultivar Olivia are more sensitive to the effect of heavy metal accumulation than the other morphological fruit parts (skin and flesh). The highest amounts of the investigated heavy metals, except Cr, were determined in the seeds, while the lowest ones, except Cu, in the flesh of oilseed pumpkin fruits. The amount of heavy metals in pumpkin biomass was not directly related to their concentrations in the soil, which proves the fact that the transfer of heavy metals from soil to plant is determined primarily by metal bioavailability and by a plant species.

    Opis:
    Juniperus communis L. is increasingly threatened in many parts of Europe, including the Baltic region. Our present study was aimed at evaluation of genetic diversity of J. communis populations of Lithuania. Fourteen selected populations differed in geography and habitats (coastal brown dunes covered with natural Scots pine forests, further referred as B; J. communis shrubs, F; transition mires and quaking bogs, D; subcontinental moss Scots pine forests, G; xero-thermophile fringes, E). Molecular variance was analyzed among populations (140 individuals, in total), employing 14 Inter Simple Sequence Repeat (ISSR) markers. Percentage of polymorphic loci differed between populations belonging to the different habitat type, being the highest for population representing habitat F (68.2%) and the lowest for populations D (42.9%). The data demonstrate the possibility to underestimate or overestimate this parameter if some habitat populations are bypassed. Means per population of Nei‘s gene diversity and Shannon‘s information indexes, were 0.158 and 0.239, respectively. Significant correlation between genetic and geographic distance of populations of J. communis was documented by Mantel test. Bayesian analysis of ISSR data has separated populations of Southern Lithuania from Northern part. Juniperus communis populations representing different habitats showed moderate interpopulation variance at ISSR loci. In ISSR-based dendrograms, individuals were correctly allocated to populations, even in case of populations growing in 0.5 km vicinity (habitats D and G). Among all populations the most distinct one was representing habitat of J. communis shrubs (F) protected by EUNIS. Principal coordinate analysis of weighted averages of Ellenberg’s indicator values (EIV) for herbaceous species, separated populations according to habitat type, while the same type analysis of ISSR data allowed distinguishing E habitat populations from populations of all other habitat type but G. Our study shows that on the local (Lithuanian) scale, molecular variance between populations of J. communis at ISSR loci might be related to habitat type. For evaluation and preservation of diversity of J. communis, different assessment methods should be included and management strategies should be directed in the way to retain variety of habitats encompassing both widely spread and less common ones.
