Jumbo Initiates Wind-Assisted Propulsion Trials on Jumbo Jubilee to Reduce Environmental Impact

Jumbo, a leader in heavy lift transport, has initiated testing of wind-assisted propulsion on its vessel, the Jumbo Jubilee, as part of a program to enhance performance and energy savings. The Jumbo Jubilee, built in 2009, has a deadweight tonnage of 13 000 and measures about 476 feet (145 meters). It is equipped with two MAK diesel engines, providing a total of 9 000 kW and enabling speeds of up to approximately 16 knots.

The retrofit includes two Econowind ventofoils—mechanical sails designed to generate additional thrust. These wings have previously shown positive results on various vessels, including short sea cargo ships in the North Sea. Their small footprint and lightweight design make them suitable for heavy lift vessels like the Jumbo Jubilee, which offers 3 000 square meters of deck space for project cargo.

Andres Cassanova, Technical Manager at Jumbo, noted that while the sails are not fully optimized for their vessel type, they will provide valuable insights into real-world fuel savings and help identify further optimizations to reduce the company’s environmental impact. The sails are mounted on a custom frame designed by Jumbo’s structural engineer, Estelle Bongers, allowing for flexibility in their placement and the option to transfer them to other vessels if necessary.

In addition to the ventofoils, Jumbo has applied an antifouling coating to the ship’s propeller and introduced an AI-powered monitoring system for the hull coating. This system collects data on vessel speed, geographic position, seawater temperature, and other environmental factors to predict fouling risks and notify the crew when maintenance is needed. This proactive approach allows for inspections and maintenance before fuel efficiency declines, using less aggressive methods to prolong the hull’s lifespan between dockings.

Furthermore, an eco-control system has been installed on the vessel, acting like intelligent cruise control. This system sets limits on fuel consumption and maximum speed, continuously adjusting RPM and propeller pitch for optimal efficiency, minimal fuel consumption, and reduced emissions. Jumbo expects to achieve significant fuel savings through these innovations and will monitor the results as part of its commitment to enhancing fuel efficiency and lowering carbon emissions.
