Caterpillar Marine has introduced a new energy-efficient hybrid propeller. It is understood that the propeller can save a lot of cost for the shipowner, and the first hybrid propeller will be put into operation this year.
     According to reports, under the condition of various partial loads, this new hybrid propulsion performance is significantly better than the traditional diesel mechanical transmission system, and can improve the fuel efficiency of various marine support vessels, saving the shipowners a lot of cost.
     According to Caterpillar, for a ship that is in standby or dynamic positioning for a long period of time, using this hybrid system will save up to 35% of fuel costs per year throughout its operational lifetime.
     Typically, Caterpillar Marine's hybrid propulsion system will help ship managers compress the ship's main engine power to optimize engine load, while also helping the ship to use diesel in low dynamic positioning or standby operation. Electrical mode.
     Caterpillar Marine said the company's hybrid propulsion system represents a new and important market competitor that can be retrofitted or installed on newbuildings. In the transport operation and in the diesel-mechanical operating mode, the smaller engine can achieve high load operation and consume less fuel. At low speeds, only one, or two generators (purchasing supply) can power the main azimuth propeller operating in diesel-mechanical mode, depending on the hull profile, at a speed of 7 In the case of Section -9, fuel savings of 10-15%. However, the greatest savings will be achieved during standby and dynamic positioning operations, as the ship will operate in diesel-electric mode and the main azimuth thruster will operate in the most efficient shift mode. By propelling a propeller with an adjustable pitch propeller, the thruster propulsion will be optimized for speed and power requirements.
