The kite propulsion has already emerged as one of the promising and attractive ways of harnessing the power of the wind to yield the financial and also environmental benefits. In order to better facilitate both design and optimization of the propulsion systems of this type, people have to possess a thorough understanding of the dynamics affecting the kite motion and all resulting forces.

The present thesis contains the results obtained from two line tension models and those results have been compared with the time histories for the flights collected during the experiments. Some new methodologies for the investigation of kite performance have been established. The first model is the "zero mass model" assuming that both kite and lines have no weight, while the second model - "lumped mass model" considers the mass of the kite and therefore makes use of the motion equation.

It has been determined that both models converge to same results in the limit where the mass of the kite is tending to zero. The publication covers such important topics related to the kite propulsion as experimental methods to record the trajectories of the flights, comparison of the models mentioned above, determination of the kite forces using 3D flight trajectories, fuel saving issues etc.

The Kongsberg Simrad GreenDP® (SDP) system is a computerized DP control system enabling automatic heading/position controls of a vessel. The system operator specifies the setpoints for position/heading; then, they shall be processed by the SDP system to provide thrust control signals to the ship's thruster plus main propeller systems.

The propulsion units which are currently in use are allocated optimum thrust by the system. The SDP system uses the information obtained from the gyrocompasses in order to control the ship's heading, and minimum one PRS, i.e. position reference system, lets the system control the position.

The cJoy wing terminal - cJoy WT (cWing) - has been designed and developed to serve as a remote joystick terminal in stand-alone joystick systems (cJoy) and DPS, i.e. dynamic positioning systems (cPos and K-Pos). The wing terminal provides all necessary facilities for manual joystick and automatic heading operations, and is designed for installation in an outside environment.

The layout of the wing terminal panel is divided into three main areas where controls and indicators are arranged according to their function. A must-have document for all personnel directly involved in the operation and maintenance of the subject systems.

The book opens with a section dedicated to the general differential equations relevant to the dynamics of ships, and the aim of this section is the derivation of the equations covering the general body motion in both inertial and body-fixed reference systems with/without principle axis; here, the author has paid particular attention to the acting forces and moments that commonly arise from the acceleration through the water.

The second section addresses the equations related to the maneuvering of the vessels with three freedom degrees, including systems of coordinates, aims and assumptions of the ship maneuvering theory, all equations and exercises for easier understanding of the theory. The next section is dealing with the determination of the added masses, while the fourth section describes the steady maneuvering forces, including their representation and experimental determination, again with some exercises.

The sixth section covers the forces acting on the ship rudders including their general representation and determination of the associated coefficients plus the interaction between the propeller and rudder of the vessel. The remaining sections of the volume are dealing with the yaw stability, transversal forces acting on propeller plus the associated yaw moment, maneuverability diagram, application of CFD methods for the maneuverability problems, and other valuable and important information.

Very rare book first published in 1885, now digitized by Google, Legends and Superstitions of the Sea and of Sailors in All Lands and at All Times was written by Fletcher S. Bassett, Lieutenant of U.S. Navy. It is culturally important as it sheds the light on many almost loss myths and stories related to the sailing.

The characters involved include the Gods, Saints and Demons of the sea, wind-makers and storm-raisers, sea monsters and sea serpents, sea-giants and dwarfs, storm-raising deeds, and many others. It also tells the reader about sacrifices, offerings and oblations, ceremonies and festivals, as well as famous sea voyages.

Introduction; Product description; Safety guideline; Control and operating elements; Crane operation; Emergency operation; Maintenance; General drawings; Hydraulic drawings; Electric drawings; Electronic; Additional documentation. Electrical symbols list, hydraulic diagram and various training materials included.

The technical documentation provided for this machine will enable the users to operate it in a safe manner, use the machine competently for all applications and perform regular maintenance. While the operating manual itself is mainly dedicated to the starting-up, operation and maintenance the second volume provides required information about the hydraulic and electrical systems...

This is a pack of technical documentation relating to the operation and maintenance of Liebherr CBW 40 cargo deck crane. It consists of three documents. First is the instruction and maintenance manual covering general technical description and also covering the important routine maintenance issues.

The second file also contains some general information followed with the description of hydraulic functions, emergency operations and complete set of drawings. The last, third, document, contains photos with hydraulic symbols, pressure limitations, direction valves, hydraulic motors, hoisting , slew and luffing gear etc.

Two documents contained in this pack provide all necessary instructions on the maintenance of the LCBW 45(40)32/20(24,4)27,5 ST type Liebherr cranes. It was specifically develop to provide the crew members as well as all technical personnel engaged in maintenance/operation of these cranes, with necessary knowledge of technical peculiarities and all other information required for the safe operation.

The first document contains the chapters 1 to 3, i.e. the introductory chapter, chapter with general description of the cranes and their parts, and maintenance instructions. The second document contains the other four chapters providing the technical description, descriptions of the hydraulic functions, instructions on the operations in case of emergency, and a full set of drawings. The readers will for sure find everything they need in this set of files and thorough familiarization with the info provided herein will provide safe and harm-free operation/maintenance of these Liebherr cranes.

Apart from the technical data, the pack provides general advice and valuable hints for crane operators, standard hand signals, conversion tables, explanation of safety signs etc.
