Marine propulsion system

Marine propulsion system plays a decisive role in the reliability and economy of ship operations.  Because the engine is at the heart of most propulsion systems and customers prefer a “one-stop-shop”, we have decided to partner with various experienced and flexible players in the propulsion and gearbox area in order to provide each customer with the best possible combination of advanced technology rather than proposing standard solutions. In times where battery technology and electric motors are developing fast, it allows us to remain on top of what the market is able to offer at the very best cost per kWh. Therefore, the propulsion engine will power your ship, allowing you to reach any port. Whether it is for you, your crew, customers or your ultimate profit, the uptime of the engine is crucial. 

We will tailor the ship’s propulsion system according to your needs. Premium gearbox, stern shaft and propeller are our perfect solution to gradually meet the unique demands of your tailor-made ship. Totally customizable supporting facilities can provide effective solutions to your most challenging demands.

Gear Box

The gearbox bears the force from the wind wheel and the reaction force generated by the gear transmission. It must have sufficient rigidity to withstand the force and torque to prevent deformation and ensure the transmission quality. We are equipped with gearboxes for medium and high speed machines for small and medium ships, for example fishing vessels, tugboats, lifeboats and other ships.

Stern shaft

The stern shaft is the last section of the propulsion system. The first end flange and the intermediate shaft flange are connected with tight-fitting bolts; the tail end is cone-shaped to install the propeller. The stern shaft is forged with high-quality carbon steel. We always have stern tube for small and medium ships, and can also be customized to suit specific ship requirements. These solutions are designed to meet the requirements and specifications of individual customers.

Propeller

Propeller is a device with a central hub and radial blades, each blade forming part of the spiral surface. When it spins in the water, it produces a pulling (pushing) force, which moves the boat forward. The propeller's pulling (pushing) force is proportional to the product of the water mass and acceleration it acts on. To achieve the most effective advancement, the mass should be large and the acceleration should be small. We provide customized services for every customer who needs a propeller.
