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…

Ship heating

Ship heating systems can be steam, water, air and electric, and modern marine vessels are widely used in air conditioning systems. There are a hundred ships on the sea. as well as on small ships of coastal inland navigation, where the use of air conditioning systems is not always economically justified, it uses arched and…

Ship sanitary systems and special systems of tankers

Sanitary systems The seawater system, like the drinking and wash water system, is a domestic water supply system. Zabortnaya.tota is used for water irrigation, washing of toilet bowls, etc. Due to the aggressiveness of sea water, the pipelines of the system, diameters of which are 10-70 mm, are made of steel ovniki, copper, copper nickel,…

Ship propulsion and their design

Ship propulsion and their design.Devices designed to create persistent pressure are perceived by the vessel, and are the root of the movement, are called propellers. There are propulsors of the evil species: lobed wheels, wing propellers, rpc6 screws, d. The propeller is a disk equipped with three or four vertical swivel blades located horizontally under…

Main parts of crank mechanisms

Main parts of crank mechanisms.Krivoshinu – a nut-gear mechanism serves to convert the reciprocating motion of the piston into a rotary motion. Crankshaft and piogo shaft (in steam engines or in internal crane engines). In machines such as piston pumps, compressors, the crank-and-rod mechanism serves to convert the rotational motion of the crank shaft into…

Anchor mechanisms

Anchor mechanisms.The following anchor mechanisms are used on sea vessels: anchors (half-brushes) anchor or anchor. mooring spiers and anchor – mooring winches. The anchor mechanisms serve to release the anchor and the anchor chain when the ship is anchored; anchoring the anchorage during anchorage; Anchoring – pulling the ship to the anchor, selecting the chain…
