Building sustainability, one ship at a time In this edition of the Green List, Michele Witthaus looks at how operators, naval architects, designers, shipyards and classification societies are improving the sustainability profile of contemporary passenger ships Shipyards and operators are increasingly cooperating on ambitious green plans for the design and build of new vessels. Ultra-luxury brand Silversea Cruises has commenced construction on Silver Nova, the first ship in its Project Evolution series, at Meyer Werft in Papenburg. Set for delivery in summer 2023, Silver Nova will run on LNG as its main fuel but will use fuel cells and batteries when berthed to become the first hybrid, luxury cruise ship that is free of local emissions at port. “Our Nova-class ships represent a significant investment in unprecedented technological solutions. They support our mission to preserve the planet without compromising on comfort or luxury,” says Roberto Martinoli, president and CEO of Silversea Cruises. Another shipyard working on environmental solutions for the ultraluxury market is T. Mariotti, owned by Genova Industrie Navali (GIN Holding). “The shipyard is contributing to improving the sustainability profile of contemporary passenger ships with the latest technologies to reduce impact on both air emission and sea pollution prevention,” says Paolo Trombetta, group marketing officer at GIN Holding. “Installation of underwater equipment also takes into consideration low noise equipment to safeguard sea mammals and marine life.” The company also specialises in waste water holding systems and alternatives to traditional ship incinerators and has delivered a new hybrid ferry to Italian Railways. Den Breejen Shipyard in the Netherlands is preparing for the future by working on multiple propulsion solutions including diesel-electric, biofuels and even fully electric river cruise vessels. “As a shipyard, Den Breejen not only stands out with contemporary ship designs, but also in showing the market that it can come up with creative and sustainable solutions,” says Johan Kaasjager, the shipyard’s commercial director. “A great example is our on-spec project Rheingold, a 135-metre river cruise vessel implementing the latest technologies like peak shaving, emergency batteries, EU Stage V certification and heat recovery.” 1 0 2 T.
