In November 2024, Maersk Tankers announced a significant investment in wind-assisted propulsion technology to enhance the environmental performance of its fleet. The company has entered into an agreement with the Spanish firm bound4blue to install 20 eSAIL® suction sails on five medium-range (MR) tankers during 2025 and 2026.
Strategic Investment for Sustainability
This initiative aligns with Maersk Tankers’ strategy to reduce fuel consumption and carbon dioxide emissions. The eSAIL® technology utilizes aerodynamic surfaces to generate lift, thereby providing additional propulsion and reducing the load on the main engines. This leads to lower fuel consumption and emissions, contributing to compliance with the International Maritime Organization’s (IMO) regulations on carbon intensity.
Collaboration with bound4blue
The agreement with bound4blue represents the largest order for wind-assisted propulsion systems for the company to date. José Miguel Bermúdez, CEO and co-founder of bound4blue, described the order as a ”key milestone” and emphasized that the trust Maersk Tankers has placed in their technology reinforces its proven capabilities in reducing fuel consumption and emissions.
Implementation and Expected Benefits
The installation of the eSAIL® systems is planned to occur during regular dry-docking periods in 2025 and 2026. Maersk Tankers anticipates achieving double-digit percentage reductions in fuel consumption and CO₂ emissions per vessel. This investment is part of the company’s broader efforts to enhance the sustainability of its operations and meet upcoming environmental regulations.
Industry Context
The shipping industry is under increasing pressure to reduce its environmental impact. Innovations such as wind-assisted propulsion are becoming more attractive as companies seek to comply with stricter emissions regulations and reduce operational costs. Maersk Tankers’ investment in eSAIL® technology positions the company at the forefront of sustainable shipping practices.
