SCHOTTEL, a leading manufacturer of propulsion systems for the maritime industry, has been selected to supply comprehensive propulsion packages for three new LNG bunkering vessels (LNGBV) currently under construction at Nantong CIMC Sinopacific Offshore & Engineering Co. Ltd, a Chinese shipyard. The vessels, designed to have a loading capacity of 20,000 cubic meters (cbm), are slated for delivery in 2026 and 2027. These vessels will serve the growing LNG bunker market, helping to support the decarbonisation and security of supply within the global shipping sector.
Two of the vessels have been ordered by UK-based LNG bunkering provider Avenir LNG Ltd, while the third has been ordered by Singapore’s Vitol International Shipping Ltd. In addition, Vitol has signed a time charter agreement for one of the vessels ordered by Avenir, which will begin in the fourth quarter of 2026. The agreement has an initial duration of seven years, with options to extend for up to ten years in total.
Each of the three vessels will be equipped with a full propulsion package, which includes SCHOTTEL’s highly efficient and reliable systems to meet the vessels’ operational demands. These systems are specifically designed to support the safe and efficient bunkering of LNG, which is one of the key alternative fuels in the maritime industry.
Key Components of the Propulsion Package
SCHOTTEL Controllable Propeller SCP 119 4-X
The primary propulsion system for each vessel will be a SCHOTTEL Controllable Propeller type SCP 119 4-X, capable of delivering an input power of 5,800 kW with a propeller diameter of 6,000 mm. This system allows the vessels to reach a free sailing speed of up to 15.5 knots. The SCP system includes a full-feathering function that enables the propeller blades to adjust to a low-resistance position when needed, improving fuel efficiency. The controllable pitch propeller provides exceptional performance and reliability, ensuring the vessels operate with minimal maintenance and a long service life. Its versatility allows the propulsion power to be tailored to the specific operational profiles of LNG bunkering vessels, making it well-suited for a wide range of operational scenarios.
SCHOTTEL Retractable Rudder Propeller SRP 380 R
Each vessel will also be equipped with a SCHOTTEL Retractable Rudder Propeller type SRP 380 R, delivering 1,300 kW with a propeller diameter of 2,200 mm. When extended, this propulsion unit functions as a fully steerable 360-degree thruster, offering excellent manoeuvrability, high propulsion power, and precise positioning. The SRP-R system is equipped with an 8-degree tilted propeller shaft, which enhances propulsion efficiency by reducing the interaction between the thruster and the hull. The retractable nature of the SRP-R allows it to be retracted into the hull when not in use, reducing drag and vessel draught during travel and port operations.
SCHOTTEL Transverse Thruster STT 2 FP
To further enhance the vessels’ manoeuvring capabilities, each will be fitted with a SCHOTTEL Transverse Thruster type STT 2 FP, rated at 750 kW with a propeller diameter of 1,540 mm. This system is designed for applications requiring high manoeuvrability, such as docking, casting off, and ship-to-ship LNG transfer operations. With outstanding performance in demanding conditions, the STT system provides the vessels with exceptional handling capabilities when performing hazardous tasks like LNG transfer in confined spaces.
Innovative Seal Monitoring System – LeaCon
The SRP-R and STT systems will be equipped with SCHOTTEL’s LeaCon seal monitoring system, which is certified by DNV for reliability and safety. LeaCon ensures that both seawater and gear oil remain securely separated, preventing contamination of the operating materials. The system actively monitors the condition of the seals, allowing for early detection of wear and reducing the risk of unscheduled maintenance. This environmentally-friendly system complies with stringent regulations and ensures the vessels’ propulsion units operate efficiently while meeting environmental requirements.
Contribution to LNG Bunkering and Global Decarbonisation Efforts
As LNG continues to be a critical alternative fuel in the maritime industry, these new LNG bunkering vessels will play a significant role in ensuring a stable and sustainable supply of LNG. With the global demand for LNG expected to grow in the coming years, the vessels equipped with SCHOTTEL propulsion packages will contribute to enhancing the security of LNG supply for the shipping sector. Additionally, as ship owners seek more fuel-efficient and environmentally friendly options, LNG bunkering vessels are expected to play a major part in reducing the carbon footprint of global shipping.
The collaboration between SCHOTTEL and the shipowners will ensure that these LNG bunkering vessels are equipped with the latest propulsion technologies, ensuring safe, efficient, and reliable operations for years to come. As part of the wider effort to decarbonize the maritime industry, these vessels will also contribute to the industry’s broader sustainability goals.
