MECHANICAL ENGINEERING

Engineers in this field design, build, test and operate machinery of all types. The field is divided into:

1) machine-tools, mechanisms, materials, hydraulics and pneumatics;

2) work and energy, heating, ventilation and air conditioning.

A mechanical engineer must be trained in mechanics and hydraulics, metallurgy and machine design. A mechanical engineer designs not only the machines that make products but the products themselves.

Naval ENGINEERING

Naval architects are engineers who design and supervise the construction of ships and ship repair. Ships must be designed to meet certain requirements such as stability, strength, floatability, reliability and many others in order to perform the type of work intended for them. Naval architects determine the shape and principal dimensions of the ship. They also carry out research work and develop calculating methods of strength and optimal parameters of the ship structure, noise reduction of the ship hull and machinery. Naval architects must be familiar with the variety of techniques in modern shipbuilding. They develop basic technologies; supervise welding operations and installation of equipment.

Marine ENGINEERING

Marine engineering is a special branch of mechanical engineering. Engineers in this field work at designing, mounting and control of ship power plants of all types (steam and gas turbines, diesel engines, nuclear and electrical power plants). They also design and investigate different types of ship engines and machinery such as ship internal combustion engines, steam generators etc., as well as technological processes of their building, mounting and operation.

Marine engineers work at designing and producing systems of power plants and information measuring complexes. Marine automation is the automatic control of shipboard systems and processes. Automatic control of a ship power plant and engine room equipment has great advantages. It increases safety of a ship power plant, reduces fuel consumption and personnel, and achieves high efficiency of the plant operation.
