ABB to modernize Quasar expedition yacht with hybrid-electric propulsion for Galápagos operations

ABB is collaborating with Ecuador-based expedition travel operator Quasar Expeditions to convert the expedition yacht Quasar Conservation to hybrid-electric propulsion for operations in the Galápagos Islands.

The vessel, formerly known as Galú, was originally built by Italian shipyard Benetti in the 1970s. Following the modernization project, it is expected to become the first hybrid-electric expedition yacht of its type operating in the Galápagos.

Hybrid-electric retrofit for low-emission operations

The 52.9-metre yacht will be equipped with ABB’s hybrid-electric propulsion package, including the Onboard DC Grid™ platform, an energy storage system (ESS), permanent magnet propulsion motors and modern diesel generator sets.

According to ABB, the propulsion system will enable the vessel to operate entirely on battery power during anchorage and short-distance crossings, reducing fuel consumption, emissions, onboard noise and vibration levels.

The vessel’s battery system will have a storage capacity of 814 kilowatt-hours.

The modernization is also intended to support compliance with environmental and noise regulations enforced by the Galápagos National Park.

Eduardo Diez, Owner and Chairman of Quasar Expeditions, said:

“Our first visit to the Galápagos in 1979 changed us forever and inspired Quasar Expeditions. Today, tourism brings both benefits and risks to these islands we love. That’s why we partnered with ABB to develop Quasar Conservation, a hybrid-electric yacht that redefines sustainable luxury without compromise.”

Extending vessel lifespan through retrofit

ABB said the modernization project is expected to extend the vessel’s operational life by up to 25 years while preserving its original design and craftsmanship.

The retrofit approach is also being positioned as a lower-impact alternative to constructing a new vessel.

Tomas Arhippainen, Business Line Manager, Marine Service & Digital at ABB Marine & Ports, said:

“Expedition cruising is one of the most technology-intensive growth segments in the maritime industry, with operators increasingly specifying advanced solutions that enhance efficiency while preserving luxury and passenger comfort. By using ABB’s hybrid-electric system, Quasar Expeditions’ Quasar Conservation perfectly demonstrates the benefits that can be achieved through a comprehensive, collaborative modernization project.”

Energy management and efficiency

ABB’s Onboard DC Grid™ platform is designed for retrofit applications where onboard space is limited. The modular power system integrates batteries and generator sets while supporting power optimization through ABB’s PEMS™ power and energy management system.

According to the company, the combined hybrid-electric system is expected to deliver improved grid-to-propeller efficiency compared with conventional mechanical propulsion arrangements.

The project reflects broader maritime industry efforts to reduce emissions in expedition cruising and environmentally sensitive operating regions through electrification and hybrid propulsion technologies.
