Prospects of development of gas turbine

Prospects of development of gas turbine. Significant! The advantages of gas turbine engines (GTE) in front of other types of main ship machinery contribute to their gradual introduction into shipbuilding. At present, the tallest ships in operation are the vessels for horse-drawn transport, equipped with a gas turbine engine with a capacity of 40,000 60,000 […]

Active steering by the courts

Types and features of active control of vessels When maneuvering in a restricted area or navigating areas with navigational hazards, the requirements to the maneuverability of the ship substantially increase, while in these conditions the ship’s speed usually decreases and, accordingly, the efficiency of the rudder falls sharply. The ship’s controllability deteriorates with a decrease […]

Classification of pumps by purpose

Classification of pumps by purpose.A pump is a mechanism designed to move a fluid that converts the mechanical energy of an engine into the energy of a fluid flow moving through pipelines. The pump is the most common auxiliary mechanism on ships.With a wide variety of pumps construction on the vessels, their purpose remains constant-the […]
