Wärtsilä Propeller Solutions Enable Energy Savings Through Slow Steaming
The modern technology team Wärtsilä will provide its Fixed Pitch Propeller (FPP) as well as EnergoProFin services for 2 container vessels had by Yang Ming Lines, the Taiwan- based delivering business. As container ship drivers remain to look for power financial savings with slow-moving steaming, the needed engine changes require to be matched by the prop setup. The Wärtsilä services allow this change, permitting the rate of both vessels to be minimized from 24 to 18 knots. The order with Wärtsilä was positioned in August 2020.
The 2 vessels, the ‘YM Mobility’ as well as the ‘YM Milestone’, are the last in a collection of 4 Yang Ming ships to be retrofitted with the Wärtsilä FPP as well as EnergoProFin services. The 2 earlier retrofit jobs have actually led to power financial savings approximately 3 to 5 percent. The freshly created Wärtsilä prop mass is about 27 percent lighter than the ships’ existing props. The EnergoProFin post-swirl tool lowers power losses from the circulation around as well as behind the prop.
“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,” claims Jackie 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,” claims Patrick Van Gorkom, Senior Manager Sales & & Sales Support, Wärtsilä Marine Power.
The Wärtsilä tools is arranged for shipment in March as well as June 2021 to the Changhong shipyard in China where the retrofitting will certainly occur.
The Wärtsilä EnergoProFin is an energy-saving prop cap with fins that turn along with the prop. This option supplies typical gas financial savings of 2 percent, with a repayment time of much less than one year. The prop’s power losses are amongst the aspects connected to the circulation sensations around as well as behind the prop manager. Installing the Wärtsilä EnergoProFin assists to minimize these power losses as well as enhance total propulsion effectiveness.
