This paper presents the methodology of strength verification during load out of the heavy cargo, in this case Arkutun Dagi SE-Topside platform. General methodology of making calculation models and load algorithms has been presented. Paper shows results of verification of global shear forces and bending moments using self-developed algorithms to modify centre of gravity, fill tanks and hydrostatically balance a 3D finite element model with commercial hydrostatic code. The NAPA and ANSYS codes were used to calculate hydrostatic pressures and to apply to 3D-FE models and to carry out strength calculation of barge construction.

The article presents the investigation results of selected effects of the side wind on the passenger ferry in sea condition. The computational fluid dynamic (CFD) analysis has been carried out in order to calculate the forces and moments acting on the ship superstructure during rolling caused by waves. The performed analysis shows the impact of rolling amplitudes and periods on results. The use of CFD method allows calculating the vertical centre of pressure with various rolling parameters. Numerical analysis has been performed for real size ship model in transient condition. The main object of the research is to define the influence of the wind dumping effect on wave rolling motions. Additional wind dumping effect (besides of other effects) is intending to use in response amplitude operator (RAO) calculations (next part of researches). It is possible that use of additional wind dumping effect will reduce the rolling amplitudes, and consequently reduce ship accelerations due to rolling motions. Reduction of accelerations (especially horizontal), should decrease the requirements due to number of cargo lashes/belts equipment and minimize the lashing time. From other side it should shorten required harbour time and reduce the ship speed, what is the best way to save the fuel.

This paper presents a functional model of river-sea ships (shortly called: SRM) operating in European system of transport corridors. It is composed of two parts: Part I contains a descriptive model of functioning the SRM fleet with taking into account various shipping tasks as well as impact factors (external and internal factors, limitations and criteria). Also, a mathematical model of functioning the SRM fleet, including choice of relevant economic criteria (e.g. profit maximization, capital return period minimization etc), is presented. Results achieved on the basis of the functional model are presented in Part II of the paper.

Artykuł przedstawia metodykę wyznaczania współczynników sił aerodynamicznych statku z wykorzystaniem numerycznej dynamiki płynów. Obliczenia numeryczne zostały zweryfikowane z wynikami uzyskanymi w tunelu aerodynamicznym. Pokazano również sposób ułożenia siatki i jej późniejszej adaptacji w celu dopasowania jej do lokalnych warunków przepływu. Duży nacisk w prezentowanej metodyce obliczeń położono na ograniczenia czasu generowania siatki i automatyzację procesu obliczeń.

The paper presents guidelines for the determination of ship aerodynamic forces with the application of computational fluid dynamics methods. Numerical calculations were verified against the results from the wind tunnel. The techniques of grid making and furhter grid adoption for local flow characteristics were discussed. Special attention was paid to the problems of time limitations during grid generation and automation of thge computation process.

The objective of paper is to present some selected problems related to initial design considerations for FPSO vessels. Genaral design issues have been briefly discussed and a proposal for the ship design process has been given. Furthermore, a statistical analysis of chosen design parameters for 140 ships already operating in the world has been carried out, and resulting formulae have been presented. Some presently available relations for the determination of natural periods have been discussed as a part of seakeeping considerations.

Design process of river-sea operating is a complex and complicated task, as it is different from the conventional design process and there is lack of experience in this matter. The main problem is to operate in many different hydrological conditions. Such a ships are operating partly in a inland waterways and deep-sea navigation conditions. It results to search for compromised requirements. This paper presents conceptual design process of the river-sea ships to be operated on the European waterways. The main objective was to find sufficient design solutions for river-sea ships to be exploited on the European river-sea waterways, fulfill the requirements expressed by the ship-freight-owners, and to keep expected flow capacity of freights and passengers.

Projektowanie statków rzeczno-morskich jest problemem kompleksowym i skomplikowanym, ponieważ odbiega od konwencjonalnego projektowania i brak jest wieloletniego doświadczenia. Ma to związek z koniecznością pracy tego typu statków w zmiennych warunkach hydrologicznych. Przez określony czas pracują w warunkach nawigacji śródlądowej albo w warunkach nawigacji dalekomorskiej. Powoduje to, iż muszą one spełniać wymagania kompromisowe. Artykuł przedstawia metodykę projektowania koncepcyjnego statków rzeczno-morskich przeznaczonych do eksploatacji na europejskich drogach wodnych. Celem tej metodyki było znalezienie takich rozwiązań projektowych statków rzeczno-morskich, które mogą być wykorzystane na europejskich trasach rzeczno-morskich w celu sprostania wymaganiom nadawców ładunków oraz przepustowości ładunków i pasażerów.

Significant increase of amount of cargoes shipped via seaway has resulted in increased amount of pollution emitted to the environment. In order to prevent the environmental degradation, decisions have been made by many countries and their organizations, that may have an influence on changing the approach towards the design process. Apart from aiming at as lowest investment and operating costs as possible until now, considering of ecological aspects leads to design modifications, which, besides reaching the basic target being the environment protection, create also new possibilities of using the space available on board the ship. In the article two variants of proecological solutions of location and type of engone room equipment on the container ship have been considered. For each solution operating costs are presented, as well as influence of the applied solutions on the ship carrying capacity.
