Hapag-Lloyd explores potential of wind-assisted propulsion container ship

German container firm Hapag-Lloyd has been exploring wind-assisted propulsion and ways to implement it technically.

Earlier this year, it launched a concept study for a 4,500 TEU container ship integrated with a wind-assisted propulsion system. The first phase of the study was completed in May.

Hapag-Lloyd has collaborated with yachtsman Boris Herrmann and professional sailing team Team Malizia for the project.

“Hapag Lloyd has been working for some time on the issue of wind-assisted ship propulsion and how this could be realised in technical terms,” Hapag-Lloyd’s strategic assets project director Christoph Thiem says.

Hapag-Lloyd’s Vision

The current wind-assisted vessel concept envisions “eight sails with a total sail area of 3,000 square metres.” While six rear sails will be extendable, the two in front will be retractable. This design will enable the vessel to evade limitations due to things like bridges, not hamper cargo operations at the port and protect the sail system.

The container ship will have a carrying capacity of 4,500 TEU.

The vessel will primarily be propelled by its engine, with the sail system only assisting propulsion. But “at slow speeds of 8 to 10 knots (15 to 20 km/h) and with the right wind conditions, the ship can also be propelled using just the sail system,” Thiem says.

As part of the project, the company is also exploring favourable shipping routes where this kind of sailing system can be implemented.

Wind-assisted propulsion systems gaining momentum

Wind-assisted propulsion systems (WAPS) have been gaining popularity among shipowners as they look for technologies that can boost vessel performance, reduce fuel use, and enhance sustainability.

Last month, Japanese shipping company Ocean Network Express (ONE) partnered with Dutch maritime wind-power tech firm Econowind to launch a six-month trial for wind propulsion technology. And Brazilian mining company Vale inked a deal with Omani shipping firm Asyad to install rotor sails on one of its chartered ore carriers.
