• Semester 5, position 4

The aim of the course is for students to master the knowledge of buoyancy and stability of the ship, as well as to learn one of the basic ship hydrostatic calculations - intact stability.

1. The student will be able to use technical skills to perform ship stability calculations based on design requirements, in accordance with the principles of good engineering practice and existing regulations; 2. The student will be able to select and apply appropriate computational and analytical techniques to solve problems of ship intact stability, considering the limitations of the applied techniques; 3. The student will be able to communicate effectively on complex engineering matters of the course subject with technical and non-technical audiences, evaluating the effectiveness of the methods used.

Initial stability of ship: righting moment, metacentric height, metacentric radius, angle of static heel, impact of wind, turning and towing, shifting loads, hanging loads and liquid cargo, dynamic stability. Longitudinal stability of ship: trim and longitudinal shifting loads. Intact stability of ship at large angles of heel: curves of centre of buoyancy, centre of flotation, and metacentre. Cross‐curves of stability. Righting arm and righting moment curves. Potential energy of stability. Ship with circular, wall‐sided and inclined sections. Static and dynamic stability diagram. Angles of static and dynamic capsizing. Practical methods of stability calculation. Parts of ship stability. Asymmetrically loaded ship and ship with negative metacentric height. Ship stability regulations.

Practical problems of ship buoyancy and stability, illustrating the subjects lectured in theoretical syllabus. In addition, students work on classical hydrostatic projects: ship hydrostatic curves and ship stability.

There are no special requirements for attendance.
