Wärtsilä Helps International Seaways Tankers Cut Fuel Costs by 5%

Wärtsilä, a technology group, has announced that it will supply its EnergoFlow and EnergoProFin propulsion solutions to four medium-range tankers in the International Seaways fleet. These solutions will be used to upgrade the ships’ existing Wärtsilä controllable pitch propeller system, resulting in an estimated five percent fuel savings. This marks the first time Ice Class 1A FS vessels will be equipped with the EnergoFlow solution, with the order being booked in Q1 2024.

By reducing fuel consumption in these MR tankers, International Seaways aims to enhance its commitment to decarbonized operations and meet Carbon Intensity Indicator (CII) requirements. The propeller upgrading project followed a comprehensive engineering study to optimize the existing propulsion systems. Michael LaGrassa, Director of New Construction and Performance at INSW, expressed excitement about the partnership with Wärtsilä and the installation of these devices as part of their sustainability journey.

EnergoFlow and EnergoProFin are innovative solutions that aim to reduce fuel consumption and emissions while improving overall propulsion efficiency. Jan Othman, Vice President of Project Services at Wärtsilä Marine, highlighted the company’s dedication to supporting the marine industry’s decarbonization efforts and expressed delight in collaborating with International Seaways to enhance the fuel efficiency of the four vessels. The vessels to be fitted with these solutions include the ‘Seaways Galle’, ‘Seaways Gatun’, ‘Seaways Hercules’, and ‘Seaways Huron’, with refitting installations planned to coincide with each vessel’s drydock schedule starting in the summer of 2024.
