Maersk Tankers deploys “suction sails” bound4blue on an MR: a concrete step toward decarbonization

Wind-assisted propulsion leaves the “pilot” stage to enter an industrial logic: bound4blue announces the successful installation of four 24-meter eSails on the MR Maersk Trieste, the first step in a larger program. The objective is clear: reduce consumption and emissions on everyday “worker” ships, where even the slightest gain in efficiency quickly translates into measurable savings on a fleet-wide scale.

Notable point: the installation was designed to limit the ship’s downtime, thru a two-stage deployment. A first phase was carried out during a scheduled dry-docking (preparation “wind-ready,” foundations, and electrical adaptations), then the final installation and connections were completed at a shipyard in Europe. This method shows how shipowners are seeking to integrate low-carbon solutions without disrupting commercial schedules.

For the market, the signal is strong: Maersk Tankers has ordered 20 sails for five MRs, which, according to bound4blue, constitutes its largest contract to date. Beyond the announcement, this confirms a fundamental trend: decarbonization will not only come thru a miracle fuel, but also thru an accumulation of operational building blocks (efficiency, optimization, equipment) capable of generating quick and verifiable gains.
