Steering Gear System In Ship The efficiency of performance of steering gear depends on some main aspects. These basic requirements to be invariably met by all steering gears are guided by rules set by classification societies. They can be briefly outlined as : As per standard requirements, the steering gear should be capable of steering […]
Steering gear application in ships We are all familiar with the use of a rudder, which helps in turning a ship as and when required. Rudders are the principal system for the entire motion and control of the ships. But we mustn’t forget that the entire rudder action is dependent on another pivotal system called the […]
Problems found in steering gear system of ships A vessel, under pilotage, departed a port in ballast and was down bound in a restricted waterway. The engine control was set to bridge control and a helmsman was using manual full follow-up (FFU) steering. At one point a port alteration was requested; however, the rudder angle indicator […]
Ship manoeuvring controls A bridge is not only for navigation but is also the command and control centre of the ship. As such it must have a comprehensive control system that connects to the engine and steering gear as well as other systems on the ship such as the navigation lights. On a modern ship […]
Excellence in electric main propulsion Electric-based main propulsion provides a great deal of freedom in ship design, and ships can be designed much more efficiently without the traditional limits on equipment layout, due to mechanical restrictions. Benefits of electric propulsion : The power can be supplied by any number of generators, which enables high redundancy. […]
Outline A Solenoid Valve Operated Wide Angle Electro-Hydraulic Steering Gear (JH Steering Gear) is capable of steering a rudder to such wide angle as 700 port and 700 starboard, and is optimum for making a Schilling Rudder exhibit its specific character. A JH Steering Gear has performance accordant with torque requirement of Schilling Rudders. A […]
Procedure of Testing Steering Gears on Ship Safety of the ship is the prime concern for seafarers onboard and for governing authorities like IMO. There have been many ship accidents in the past which includes collision, grounding, stranding etc. due to failure of one critical system- the steering gear. Hence crew must be careful in […]
