Taiwan-based shipping company Yang Ming Lines has opted to install Wärtsilä’s Fixed Pitch Propeller (FPP) and EnergoProFin solutions across two of its container vessels to enable the vessels to slow steam. 

The Wärtsilä solutions enable a ship’s engines to be adjusted to match the propeller arrangement, which is essential for slow steaming. This adjustment will allow the speed of the two vessels to be reduced from 24 to 18 knots.

The order with Wärtsilä was placed in August 2020.

The two vessels, the ‘YM Mobility’ and the ‘YM Milestone’, are the last in a series of four Yang Ming ships to be retrofitted with the Wärtsilä FPP and EnergoProFin solutions. The two earlier retrofit projects have resulted in energy savings in the region of three to five per cent. The newly designed Wärtsilä propeller mass is approximately 27 per cent lighter than the ships’ existing propellers. The EnergoProFin post-swirl device reduces energy losses from the flow around and behind the propeller.

“The two retrofit propeller projects already completed with the Wärtsilä systems have been very successful, which is why we had no hesitation in taking the option to do the same with these two vessels. Wärtsilä was also able to meet our tight delivery schedule requirements, and we are very happy with the support they have provided,” saidJackie Ho, chief technical officer, Yang Ming Lines.

“Efficiency and cost savings are extremely important in today’s operating environment, and the Wärtsilä propulsion solutions are designed to meet these needs. By enabling the engine power to be reduced, we are also enabling fuel consumption to be lowered, which in turn also leads to fewer exhaust emissions,” commented Patrick Van Gorkom, senior manager sales & sales support, Wärtsilä Marine Power.

The Wärtsilä equipment is scheduled for delivery in March and June 2021 to the Changhong shipyard in China where the retrofitting will take place.
