SCHOTTEL has been selected to provide high-efficiency electric rudder propellers for two 20,000 cbm LNG bunkering vessels operated by Shanghai International Port Group. Featuring the innovative LE-Drive and MariHub IoT monitoring, these vessels will enhance maneuverability and operational reliability at the Port of Shanghai starting in 2027.
Germany | May 7, 2026 – SCHOTTEL, a global leader in steerable propulsion, has been awarded the contract to supply advanced rudder propellers for two 20,000 cbm LNG bunkering vessels. Operated by Shanghai International Port Group (SIPG) and under construction at Jiangnan Shipyard, these vessels are set to become pillars of China’s maritime decarbonization strategy upon their delivery in April 2027.
As the shipping industry transitions to cleaner fuels, the demand for precise maneuverability during ship-to-ship (STS) bunkering has never been higher. SCHOTTEL’s technology ensures these massive bunkering vessels can maintain pinpoint accuracy alongside the world’s largest container ships, even in the high-traffic waters of Shanghai.
Efficiency Through “Embedded” Electric Propulsion
To meet modern emission standards, the vessels will utilize a fully electric propulsion system featuring the SCHOTTEL SRP 460 LE (Embedded L-Drive).
By integrating the electric motor vertically into the rudder propeller, SCHOTTEL has eliminated the upper gearbox. This design offers several critical advantages for bunkering operations:
- Increased Mechanical Efficiency: Direct power transmission reduces energy loss.
- Compact Footprint: The low installation height allows for more efficient hull design.
- Operational Comfort: Significant reductions in noise and vibration levels for the crew.
- Lower OPEX: The SCHOTTEL ProAnode system protects against corrosion while its hydrodynamic shape reduces fuel consumption.
Digital Intelligence with MariHub
Beyond hardware, the vessels will be “smart” ships. Both will be equipped with MariHub, SCHOTTEL’s IoT gateway. By recording and analyzing real-time data from machinery sensors, the system enables condition-based maintenance. This proactive approach minimizes downtime, a vital factor for SIPG, which manages one of the world’s busiest bunkering schedules.
Securing the Global LNG Supply Chain
With global LNG demand surging, these 20,000 cbm vessels represent a significant scale-up in capacity. By investing in high-spec European propulsion for Chinese-built hulls, SIPG is positioning Shanghai as a premier global hub for LNG bunkering, ensuring security of supply for international fleets.
