Shipowners: Discover Your Ideal Split Shaft Generator Solution Here
The shaft generator system for ocean-going ships has become a new favorite in the industry. A large number of newly built ships have adopted the shaft generator system as a standard configuration to further improve ship energy efficiency. More importantly, this device can bring continuous and considerable economic returns to shipowners. Nowadays, as carbon emission regulations are gradually tightened, operating ships are facing more severe situations due to their less optimistic energy efficiency indicators, and their need to improve energy efficiency is more urgent. The shaft generator system has also become one of the important solutions for operating ships.
Shanghai Marine Diesel Engine Research Institute (SMDERI) as a leader and pioneer of high-power shaft generator devices in China, has leveraged its profound technical expertise in ship propulsion systems and rich engineering experience to launch the Split Shaft Generator System solution with fully independent intellectual property rights, based on the demand of the ocean-going ship market. This innovative solution is not only suitable for newly built ships but also demonstrates excellent performance in the renovation projects of operating ships, significantly reducing renovation cycles and costs, showing strong market competitiveness. Since the delivery of the first MW-class shaft generator system in 2022 , SMDERI has won orders for more than 80 ship sets of split-type shaft generator systems and delivered over 20 ship sets, becoming a leading domestic supplier of high-power shaft generator systems for ocean-going ships.
- Split Shaft Generator System: Addressing the Pain Points of Retrofitting Operating Ships
The Split Shaft Generator System developed by SMDERI focuses on the difficulty of retrofitting operating ships. It allows retrofitting without changing the ship’s shafting system, significantly reducing the complexity, time, and cost of the retrofitting process. The “Lida” retrofitting project, undertaken by SMDERI, was completed in just 15 days from the ship’s arrival at the factory to the completion of the system modification （https://mp.weixin.qq.com/s/JZGh8g4081ZJSMiJIG1mog）. This considerably saved time and cost for the shipowner, further highlighting the advantages of the Split Shaft Generator System in retrofitting operating ships. With the ability to complete the retrofitting project within a single dock repair period, the SMDERI’s Split Shaft Generator Systemis poised to become a preferred solution for shipowners.
- Split Shaft Generator System: Creating Multiple Benefits for Shipowners
Shipowners benefit from more than just energy efficiency improvements with the Split Shaft Generator System from SMDERI. In the retrofitting project for the OCEAN series of 230,000-ton operating ships, SMDERI provided a comprehensive energy efficiency solution combining hydrodynamic modifications with a 1300kW shaft generator system. This solution helped improve the ship’s EVDI rating from E- to C+, while saving the shipowner nearly 10% in fuel consumption per day, equivalent to over 3.5 tons. Similarly, another 180,000-ton bulk carrier, the AASHNA, has been saving an average of 1.8 tons of fuel per day since the installation of a 1200kW Split Shaft Generator System in February 2023. This has observably reduced the operation and maintenance costs of auxiliary equipment, resulting in a comprehensive investment recovery period of only 2.8 years.
- Split Shaft Generator System: Significant Fuel Savings and Friendly Maintenance Mode for Newly Built Ships
Newly built ships also benefit greatly from the split-type shaft generator technology. SMDERI has undertaken the construction of four new 210,000-ton bulk carriers for the Zhonghua series, which are scheduled for delivery in April and June 2023, and April and May 2024, respectively. These ships are equipped with a 1000kW Split Shaft Generator System that not only meets the energy efficiency requirements of the ships but also provides higher speed options and navigational benefits, resulting in daily fuel savings of over 1 ton.
On top of this, the “split” structure also facilitates easier periodic maintenance and servicing of the shaft generator equipment and shafting system. During the navigation trial phase, the Split Shaft Generator System completed all tests in just 6 hours, demonstrating high team efficiency and system stability, which was highly recognized by the shipyard .
- Split Shaft Generator System: Reliable One-Stop Service
As a renowned domestic power research institute, SMDERI boasts a team with comprehensive expertise in power and leading technology in China. We provide shipowners with one-stop solutions for shaft generator systems! From system design, equipment supply, installation, and commissioning to after-sales service, SMDERI ensures the interests of shipowners in all aspects. Our own 4.5MW medium and low-voltage test benches allow for comprehensive system testing of the shaft generator before installation on the ship, guaranteeing product performance and providing peace of mind for both the shipyard and the shipowner.
By choosing SMDERI’s Split Shaft Generator System, you are not only selecting a valuable assistant that can help improve ship energy efficiency, reduce operating costs, and address carbon emission challenges, but also a trusted lifelong partner.
