Wärtsilä EnergoProFin energy-saving solutions increase propeller efficiency with up to 5% fuel savings
Â
     It is reported that Wärtsilä's EnergoProFin is a specially designed propeller cap with fins on the rear side of the propeller. It is an innovative energy-saving device that significantly reduces the fuel consumption of ships and their emissions levels. This technological innovation plays an important role in effectively controlling the rising ship operating costs by improving the efficiency of the existing fleet operations. Through the improvement of energy efficiency, shipowners can improve their profitability and meet environmental protection requirements.
Â
     Propeller caps with fins have been in use for 30 years, but so far they have been used primarily on FPP. According to industry opinion, it is impossible to apply the same energy-saving device as Wärtsilä EnergoProFin to the technically more challenging CPP. However, Wärtsilä has successfully developed and produced this product, providing opportunities for ships equipped with CPP to reduce energy consumption. Wärtsilä's technological innovation development is a result of a collaboration between the EU and nine Other companies.
     Energy saving affects operating costs and meets environmental requirements
Â
     The Wärtsilä EnergoProFin, which rotates with the propeller, is used to optimize the propulsion power upgrade of existing ships, with simple installation and no complicated structural changes. The device is designed to convert rotational energy into effective thrust, minimizing eddy current losses, resulting in increased efficiency and fuel savings of up to 5%. Even if the current fuel price level is low, the return on investment generally does not exceed two years, and can even be shortened to no more than one year.
Â
     “In today's uncertain economic climate, customers need reliable, cost-effective, and easy-to-invest in solutions. Energy efficiency solutions are a good investment because their impact on operating costs and meeting environmental requirements is sustainable. "Tamara de Gruyte, vice president of system services for Wärtsilä Service, said. “We want to help shipowners optimize their existing fleets. This is what Wärtsilä EnergoProFin has done, and now it also applies to adjustable paddles.

     GNV values ​​energy efficiency
Â
     Clients love these innovative technologies and solutions that can help them increase their efficiency. The Italian shipping company GNV operates 10 international routes to and from Spain, France, Albania, Tunisia, Morocco and Malta, as well as 5 domestic routes within Italy, and continues to invest in the energy optimization of its fleet. The company is rapidly adapting its product mix and services, focusing on market signal changes and ongoing technical upgrades to its fleet, enabling GNV to update and strengthen its existing operations to consolidate domestic routes and enhance its presence in the international market. Business.

     Antonio Campagnuolo, Director of Marine Operations at GNV, said: "Our strength is the company's extreme and sustained focus on the energy efficiency of its fleet. Once we wanted to replace the propeller blades of the two ships, we explained further in Wärtsilä. After EnergoProFin products and we analyzed their performance and the resulting energy efficiency improvements, we finally decided to install the EnergoProFin solution for the blade replacement program on both ships."
