Wartsila has received an order to supply its EnergoProFin and Fixed Pitch Propeller (FPP) solutions for two container ships owned by Yang Ming Lines, a Taiwan-based shipping company.
The order with Wartsila was placed in August.
The engine adjustment, along with propeller arrangement, will enable Yang Ming Lines to save energy through slow steaming.
Moreover, Wartsila solutions will reduce the speed of the two vessels, YM Mobility and YM Milestone, from 24k to 18k.
These two vessels are the last in a series of four Yang Ming ships to be retrofitted with the Wartsila FPP and EnergoProFin solutions.
The company said that the earlier two retrofit projects resulted in energy savings of 3%-5% in the region.
The newly designed Wartsila propeller mass is nearly 27% lighter than the ships’ existing propellers, while the EnergoProFin post-swirl device will reduce the loss of energy from the flow around and behind the propeller.
Wartsila EnergoProFin will also help to increase overall propulsion efficiency. It is an energy-saving propeller cap with fins that rotates with the propeller.
The solution offers average fuel savings of 2%.
Yang Ming Lines chief technical officer Jackie Ho said: “The two retrofit propeller projects already completed with the Wartsila systems have been very successful, which is why we had no hesitation in taking the option to do the same with these two vessels. Wartsila was also able to meet our tight delivery schedule requirements, and we are very happy with the support they have provided.”
Wartsila Marine Power senior manager for sales and sales support Patrick Van Gorkom said: “Efficiency and cost savings are extremely important in today’s operating environment, and the Wartsila 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.”
Wartsila equipment is scheduled for delivery in March and June 2021. The retrofitting will take place at Changhong shipyard in China.
