On the issue of carrying out mooring tests of a ship power plant in shallow water conditions

Abstract

In the process of mooring trials, as well as when ships are sailing in shallow water, difficulties often arise in ensuring normal operating conditions for the propulsion complex, the performance of the power plant and the ship as a whole. The article outlines the problems during mooring tests in shallow water. Mooring tests of a large-tonnage tanker in shallow water conditions are considered, when the operation of the main circulation pump of the cooling system is disrupted due to contamination of the flow path of the main condenser with soil particles. The economic inexpediency of testing a tanker at sea when it is anchored or barreled in an area that is safe for navigation and has sufficient water depth is substantiated. The method of taking cooling water from above with the help of a caisson is considered, which eliminated unproductive costs. A method of mooring a ship is given, in which the water jet from the propeller does not harm the berthing facilities and does not erode the soil of the water area; the means of simulating the nominal parameters of the actuators are described, which makes it possible to carry out mooring tests of mechanisms, systems and devices without bringing the main power plant to the mode of increased loads, and, as a result, to reduce the testing time.
