Wärtsilä technology group will provide its advanced thruster solution for a new hybrid tug being built to operate in the port of Xiamen in China. The selected Wärtsilä thrusters have been specially designed for electric propulsion and meet the vessel’s durability requirements. The tug is under construction for Xiamen Port Shipping at Fujian Mawei shipyard. The order with Wärtsilä was placed in June 2022 by Shanghai CSIC Marine Propulsion Equipment, the integrator of the new build project.


The project specifications emphasize emission reduction and energy savings. The tug will operate with two Wärtsilä WST18FP-L steerable thrusters, providing optimum propulsion performance in line with sustainability requirements.


“Decarbonisation is at the heart of Wärtsilä’s design strategy, and WST thrusters reflect the innovative development of our core propulsion systems supporting this strategy. We are also able to support the customer with local production, engineering and after-sales service in China, which makes Wärtsilä an excellent choice for the full tug life cycle. I am very happy that the port of Xiamen, Fujian Mawei Shipbuilding and Shanghai CSIC have chosen us as their partner for the future flagship project of this industry,” said Lauri Tiainen, director of thrusters and propulsion control systems..


Wärtsilä WST18FP-L thrusters provide excellent thrust on bollard pull and transit speed performance. They feature high hydrodynamic capacities, less maintenance, easy installation and better accessibility for maintenance. The WST series includes eight thruster types, ranging from 700 to 3300 kW, enabling vessels to meet and exceed the performance levels required in today’s competitive operating environment.


Xiamen Port is a major deep-water port in China’s Xiamen Fujian Province. The 5,000 HP tug is 38.3 meters long and is expected to enter operational service in 2023. The Wärtsilä equipment will be delivered in the first quarter of 2023.
