The Energy Efficiency Design Index (EEDI) became mandatory for new ships as well as the Ship Energy Efficiency Management Plan (SEEMP) for all ships due to the MEPC 62 (July 2011) along with the adoption of amendments to MARPOL Annex VI by the Parties to the MARPOL Annex VI. This was the first legally binding climate change treaty to be adopted since the Kyoto Protocol. The Ship Energy Efficiency Management Plan (SEEMP), which has been obligatory since 2013, did not to cover fishing cutters but triggered the implementation of energy efficiency audits due to fishing limits, high fuel prices, and free freight market. All the above caused that ship-owners started seeking ways for saving money and keep their business profitable. Apart from energy recovery installations, fishing vessels have been furnished with the latest technologies aimed at the reduction of energy consumption and at making ships greener. A research team of the Maritime University of Szczecin conducted energy efficiency audits on several fishing vessels operated on the Baltic Sea and stated that up to 40% of the energy is used during fishing operations by hydraulic devices installed at the fishing vessels. The paper presents the measurement results of energy consumption in typical operational states based on a selected fishing cutter operating at the Baltic Sea. The paper includes also the recommendations in terms modernization of hydraulic installations and the changes of control methods for devices with hydraulic drive. The calculations are also presented herein and they prove that it is possible to reduce energy consumption by a fishing cutter even by 20% while maintaining the unchanged operating parameters of the hydraulic devices.

In recent years lean thinking (also referred as slim) increases its popularity not only in industry, but also in the entire business world. There are many confirmed effects demonstrating the high effectiveness of this philosophy: a clear improvement of economic indicators, an increase in current satisfaction and the acquisition of new clients; better, stable quality of offered products and services; efficient organization of production; more effective management; high productivity of work and production; minimizing the costs of production and storage of stocks. Why is Lean implementation in our domestic conditions not easy and sometimes ineffective? In this study we will try to answer these very important questions.

The search for new polymer processing ways has become necessary due to the rapidly growing technology and market needs. The time of manufacturing products, as well as the impact of process parameters and the design itself on the properties of materials have become very important. Therefore, the creation of assumptions allowing the construction of a compact device whose construction will allow, for example, high process efficiency at low screw rotational speeds or a high degree of material homogenisation, is expected by the market. However, this requires the design of new or continuous modifications and improvements to existing structures.

A research team of the Maritime University of Szczecin conducted energy efficiency audits on several fishing vessels operated on the Baltic Sea and provided the results to the shipowners. On their grounds, the shipowners started seeking methods to reduce energy consumption. They began modernizing the vessels using the information collected in the reports on energy audits. Usually, the modernization process is performed in severa stages. Apart from energy recovery installations, fishing vessels were furnished with the latest technologies aimed at the reduction of energy consumption and at making ships greener. The paper presents results of the said process at the selected fishing cutters operating on the Baltic Sea. The paper includes also the recommendations on the directions of the following stages of the audits.

W artykule przedstawiono autorski program komputerowy umożliwiający wykonywanie obliczeń wskaźników ekonomicznych inwestycji na jednostkach rybackich. Procedury obliczeniowe opracowano z wykorzystaniem danych literaturowych oraz metodyki dostosowanej o specyfiki jednostek polskiej floty rybackiej. Dane niezbędne do obliczeń i analiz pochodzą z wyniku finansowego, bilansu oraz danych zewnętrznych. Mogą być wprowadzane przez armatorów i być gromadzone w bazie danych stanowiącej integralną część programu komputerowego. Obliczenia można wykonywać z wykorzystaniem danych uzyskanych podczas eksploatacji kutrów w celu uzyskania wartości rzeczywistych wskaźników ekonomicznych jednostki, jak również symulować i sprawdzać nowe warianty rozwiązań finansowania i opłacalności eksploatacji jednostek rybackich.

This article discusses requirements for the extinguishing systems in the engine room. The sources of fire hazards in engine rooms were characterized. The causes and consequences of selected engine room fires that occurred within the last five years were presented. The basic requirements for the fire-extinguishing systems installed in engine rooms were scrutinized. The most commonly used fire-extinguishing systems in engine rooms are the ones containing a gaseous extinguishing agent. Their main advantages are short response time after agent release and the ability to supply an extinguishing medium to areas that are hard to access. The agent used in such systems does not cause damage and there is no need to remove its residues after fighting the fire, as in the case of other agents such as foams. As an example, a CO2 system was characterized, as it is the most frequently used in engine rooms.

The International Maritime Organisation (IMO), in particular, dedicated to the prevention to marine pollution by ships, adopted in 2007 the provisions implementing the Energy Efficiency Design Index (EEDI). The EEDI was implemented as an amendment to the MARPOL Annex VI. The index specifies the technical standards and norms imposed on shipyards, which shall be intended to improve the energy efficiency of certain categories of new ships and vessels, consequently leading to the reduction of CO2 emission by around 25-35 percent till 2030. The paper presents the operational factors affecting fuel consumption and energy efficiency indexes of a ship, the algorithm of verification and certification of the EDDI along with exemplary calculations for a container ship.

The paper presents possibilities regarding the management of electric power and mechanical energy at polish fishing vessels on the example of power, pump and ventilation systems. The aim of the said possibilities is to reduce and limit fuel consumption and to reduce the impact of exhaust gases on the environment.. In both systems there are the possibilities to control the flow volume, to reduce static and dynamic discharge pressure and to manage flow volume on the grounds of volume control instead of throttle control. The identification of the possibilities to manage energy requires detailed assessment of a current method regarding working media application.

W artykule przedstawiano możliwości zarzadzania energia mechaniczna i elektryczna jednostek rybackich, na przykładzie okrętowych instalacji energetycznych, pompowych i wentylacji mających na celu ograniczenie zużycia paliwa i zmniejszenie oddziaływania gazów wylotowych na środowisko naturalne. W obu instalacjach istnieją możliwości sterowania wielkością strumieni, redukcji statycznego i dynamicznego ciśnienia tłoczenia oraz sterowania wielkością strumienia w oparciu o regulację objętościową zamiast dławieniowej. Identyfikacja możliwości zarządzania energią wymaga szczegółowego oszacowania aktualnego sposobu wykorzystania mediów roboczych.
