Propeller & Propulsion System.
Propeller System
A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade. Propeller dynamics, like those of aircraft wings, can be modelled by Bernoulli’s principle and Newton’s third law. Most marine propellers are screw propellers with fixed helical blades rotating around a horizontal (or nearly horizontal) axis or propeller shaft. Propeller types and related components:
- Azimuth Thruster
- Controllable Pitch Propeller (CPP)
- Fixed Pitch Propeller (FPP)
- Stern Tube Seal
- Seal for Thruster
- Stern Tube Bearing Bush
Propulsion System
The propulsion system on a vessel can be as simple as a diesel engine directly connected to a propeller shaft, which drives the propeller, or more complex systems containing diesel engines powering an electrical generator, supplying electrical power to an electrical motor through a sophisticated control system. The set-up of the propulsion system depends on the vessel size, trade or type of operation.
Based on your vessel’s design and drawings, we can provide a suitable propulsion system, together with integrated solutions and services that optimize the lifecycle value of your installation. We focus on operational efficiency, environmental performance and fuel flexibility, and work closely with you throughout the project.
