Spanish wind-assist technology company Bound4blue has announced the successful installation of four eSails on the tanker Maersk Trieste, marking the first delivery under a major contract with Maersk Tankers.
The vessel has been fitted with four 24-meter suction sails (eSail). Preparatory work was carried out at Yiu Lian shipyard in China, while final installation was completed at EDR shipyard in Belgium. Bound4blue said its plug-and-play approach enabled the retrofit to be completed with minimal vessel downtime.
The framework agreement, signed in December 2024, covers the supply and installation of 20 eSails across five vessels operated by Maersk Tankers.
According to Bound4blue, each eSail system is tailored to the specific ship and can deliver double-digit percentage reductions in fuel consumption and CO₂ emissions. The savings can also support compliance and performance under regulations such as FuelEU Maritime, CII, and EEXI.
