ABB upgrade converts Galápagos expedition yacht to hybrid-electric Quasar Conservation

As well as extending Quasar Conservation’s operational life by up to 25 years, the modernization project preserves the yacht’s classic aesthetic and craftsmanship – and is more cost-efficient and sustainable than building a new vessel.      The conversion from conventional combustion engines to hybrid-electric propulsion will allow guests on board the 52.9-meter vessel to experience quiet, comfortable, and low-emission sailing in one of the world’s most sensitive biosphere reserves.

Comprising the ABB Onboard DC Grid power system platform, energy storage system (ESS), permanent magnet propulsion motors, and modern diesel gensets, the hybrid-electric propulsion system will allowthe vessel to operate entirely on battery power at anchor and during short crossings. In addition to minimizing fuel consumption, this will support compliance with Galápagos National Park’s strict noise and emission regulations.

“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,” said Tomas Arhippainen, business line manager, marine service & digital, at ABB’s Marine & Ports division. “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.”      Well-suited to space-limited retrofit applications, ABB’s Onboard DC Grid provides the high fault-tolerance levels critical for exploration cruise vessels operating in remote waters. The modular DC power platform enables the seamless integration of the 814-kilowatt-hour battery ESS and modern diesel gensets. With ABB’s PEMS\ power and energy management system optimizing the use of total onboard energy resources, this combined hybrid solution – including highly efficient permanent magnet motors – offers significant grid-to-propeller efficiency gains compared to conventional mechanical drivetrains.
