    Opis:
    The paper shows purposefulness and possiblity of automation of ship propulsion systems, especially those of POD type, intended to be used on four Baltic navigation ships: a containership, ro-ro ship, product tanker, as well as river-sea-going ship, designed within the frame of the Eureka "Baltecologicalship" project. Requirements of ship classification societies, and general ones for modern ship control systems were presented, as well as a review and analysis of currently applied power plant automation systems for diesel- electric ships fitted with podded propulsion drive (POD), were performed. Moreover real ways and possibilities of controlling ship s course and speed were indicated. Information contained in this paper may facilitate selecting appropriate design assumptions for a propulsion control system to be applied on the above mantioned ships.

    Opis:
    This paper presents an analysis of environmental and technical conditions necessary for working out a possibly most favourable propulsion system for a two – segment passenger ship intended for navigation between Berlin and Kaliningrad. There are presented various types of propulsion systems for small ships as well as analyzed their possible applications and consequences. In this work there were taken into account system’s reliability, efficiency, dimensions, mass and costs of manufacturing, assembling and possible replacing the system components as well as an impact on maneuverability and natural environment. With taking into account the above mentioned criteria it was finally found that the diesel-hydraulic system fitted with two azimuthal ducted solid propellers is the most favourable. There are also presented a schematic propulsion and control diagram, three-dimensional arrangement drawing of system components as well as assembly drawing of the designed azimuthal propulsion system.

    Opis:
    The paper deals with synthesis of automatic control system for an unmanned underwater robotic vehicle. The problem of determining permissible propulsive forces and moments necessary for optimum power distribution within a propulsion system composed of azimuth propellers (rotative ones). To allocate thrusts the unconstrained optimization method making it possible to obtain a minimum-norm solution, was applied. A method was presented for assessing propulsion system capability to generate propulsive forces (set control inputs). For the case of lack of such capability an algorithm was proposed making modification of their values and determination of feasible propulsive forces (i.e. permissible control inputs), possible. A numerical example which confirmed correctness and effectiveness of the proposed approach, was also attached.

    Opis:
    The paper presents simulation investigations of influence of gas turbine controller adjuŹstment on ship propulsion system operating in heavy sea conditions, based on the model presented in Part 1 of the paper. The ship propulsion system with two gas turbines driŹving - through mechanical gear - ship controllable pitch propeller, described in Part 1, was used to analysis. The harmonic disturbances due to sea waves with selected frequencies were used as input function in computing the system’s amplitude characteristics at different settings of P and PD controllers.

    Opis:
    The problem of reduction of greenhouse gas emissions in shipping is currently addressed by many research works and related industries. There are many existing and visionary technologies and ideas, which are conceptually defined or practically realised. This goal can be achieved in different ways, and reducing fuel consumption is one of the major methods. In these circumstances, the aim of this study is to analyse the possibility of fuel consumption reduction by using an alternative control strategy for low-speed marine diesel engines which would take into account the interactions between hull, propeller and main engine. For this purpose, a mathematical model including ship hull and propulsion system is developed. A case study is conducted for a ship for which the results of both the ship hull and screw propeller model tests are available. A low-speed two-stroke diesel engine is then selected for the considered ship. Two different governors are included in the model and their parameters are changed to investigate the dynamic behaviour of the system when simulating the forward acceleration mode in calm sea conditions. The research is mainly focused on variations of fuel consumption by the ship passing a certain distance to reach the nominal constant speed. It is concluded that, for a given travel distance, it is possible to save considerable amount of fuel at the expense of slight increase of journey time.
