By Shardul SharmaTechnology company Wartsila announced on October 5 that it will supply its recently introduced 25DF dual-fuel (LNG) engine for two new sail-assisted luxury cruise ships being built at the Chantiers de l'Atlantique (CdA) shipyard in France for Orient Express Silenseas, part of French hospitality group, Accor. There is an option for an additional two vessels.
The 25DF engine features a two-stage turbocharging system, common rail fuel injection, and cylinder-wise combustion control. This enables unparalleled power density and efficiency across the full operating range, delivering low fuel consumption and reduced emissions.
"The Wartsila 25DF is an engine that supports the shipping industry's transition to greater fuel efficiency and a much-reduced carbon footprint," commented Stefan Nysjo, vice president, power supply, Wartsila Marine Power. "It marks the beginning of a new era of future-proof medium-speed, small-bore engines, and comes as an important step towards the maritime industry meeting its decarbonization goals."
The full scope includes for each vessel four 25DF engines, each developing 2070 kW at 1000 rpm, four gas valve units, and four NOx reducer emission after-treatment systems. The equipment is scheduled for delivery to the shipyard commencing in autumn 2024.
The first of the 220-meter-long vessels will be named the Orient Express Silenseas. The ships are designed to accommodate approximately 116 passengers.
