bound4blue celebrates the completion of its first tanker installation with a seamless, single-stop eSAIL® deployment on the 50,000dwt Pacific Sentinel, completing the entire process in one shipyard visit.

Installation marks Eastern Pacific Shipping’s (EPS) first move into wind-assisted propulsion, enabling double-digit fuel savings while enhancing cost efficiency and ensuring seamless regulatory compliance.
bound4blue has completed the installation of its breakthrough eSAIL® suction sails on tanker vessel Pacific Sentinel with a streamlined single-stop process for Eastern Pacific Shipping (EPS) at Besiktas Shipyard in Turkey during a planned drydocking.
Three 22-metre, DNV Type Approved eSAILs® were installed on the 50,000dwt Pacific Sentinel in under a day per unit, as planned. The installation took place during a scheduled vessel drydock, with preparatory work completed in advance.
The fully autonomous wind-assisted propulsion system (WAPS) will help the vessel reduce overall energy consumption with forecasted energy consumption savings of around 10% depending on vessel routing, slashing OPEX and emissions to air, while also enhancing regulatory compliance.
Fast-track, single-stop benefits
The installation heralds a landmark in numerous regards, signifying EPS’ first step into wind-assisted propulsion – as a continuation of its ambitious decarbonisation programme – while also marking bound4blue’s first tanker installation. The Spanish-based wind pioneer has undertaken a fast-track “single-stop” process, ensuring minimal vessel downtime with all work undertaken during planned vessel maintenance at the shipyard.
The fast-track, single-stop installation combined vessel groundwork, such as fitting pedestals for the eSAILs® and welding, with the simultaneous preparation and programming of the sails. This efficient approach helped minimize installation time.
The vessel and sails were fully prepared in advance
David Ferrer, Co-founder and CTO, bound4blue explains: We’re committed to helping shipping companies, such as EPS, embrace clean, proven, wind power in the simplest, most cost efficient and effective manner.
Thanks to our collaboration with shipowners, operators, shipyards, and other key partners in all installations carried out by bound4blue, we have achieved a quick, robust, and high-quality deployment procedure.
In this case the vessel and sails were fully prepared in advance, ensuring they could be lifted and bolted into place without extending the planned time at the yard.”
Ensuring regulatory compliance
The installation was completed along with guidance from the American Bureau of Shipping (ABS), ensuring compliance with classification and safety standards. ABS played a crucial role in granting the ‘wind-assisted’ notation, which was key to the structural integration of the eSAILs® with the vessel and ensuring alignment with regulatory frameworks such as the EU ETS, CII, and FuelEU Maritime.
Sustainable partnerships
bound4blue has installed its solution on five vessels, with many more in its growing order book. EPS, which signed the agreement for the Pacific Sentinel in February 2024 and has now successfully completed this installation, further extended its collaboration with bound4blue in December 2024 through a new agreement for the installation of three eSAILs® on an MR tanker under construction at New Times Shipbuilding in Jiangsu Province, China. This installation is scheduled for late 2025.
Delivering progress
The eSAIL® units work by dragging air across an aerodynamic surface to generate exceptional propulsive efficiency. The technology is suitable for both newbuilds and retrofitting across the huge majority of vessel segments, including, but not limited to, Tankers, Bulkers, Ro-Ros, Cruises, Ferries, Gas Carriers, and General Cargo vessels.
eSAILs® help shipping companies simplify compliance, and achieve advantage, with regulations including EU ETS, CII and FuelEU Maritime, while offering a typical payback of less than five years.
