Propeller Cavitation Causes and Remedies As the propeller turns it absorbs the torque developed by the engine at given revolutions i.e., the delivered horsepower – and converts that to the thrust which, in turn, pushes the vessel through the water. According to Bernoulli’s law the passage of a hydrofoil (propeller blade section) through the water causes […]
Dynamic positioning operator for ship You would use computer systems to control a ship so it can stay in one position and remain stable in the sea. Your vessel could be a ship or a semi-submersible involved in : Supplying offshore oil and gas platforms. Drilling operations. Laying pipes on the seabed. Setting up renewable […]
Dynamic Positioning Operation For Ship Rudder Dynamic positioning (DP) is a computer-controlled system to automatically maintains a ship’s position and heading by using its own propellers and thrusters. Position reference sensors, combined with wind sensors, current sensors and gyro compasses, provide information to the computer pertaining to the vessel’s position and the magnitude and direction […]
