Technology group Wärtsilä and Carnival Corporation have entered into an 8-year lifecycle agreement covering four cruise vessels within the Princess Cruises and Carnival Cruise Line fleets, including two newbuild vessels currently under construction.

The agreement, which was booked by Wärtsilä in Q2 2026, marks the first service contract between the two companies covering Carnival Corporation’s LNG-fuelled cruise ships. Under the terms of the deal, Wärtsilä will provide lifecycle maintenance support for the vessels’ Wärtsilä dual-fuel engines and related equipment.

According to Wärtsilä, the agreement is structured around performance-based outcomes, including lower unscheduled maintenance costs and fewer unplanned stops. The scope covers planned and unplanned maintenance support, spare parts supply and logistics, major engine overhauls, remote monitoring and condition-based maintenance, technical audits and performance reviews, advisory services, crew training, and performance management through agreed key performance indicators.

Vera Lannek, Vice President, Strategic Sourcing & Asset Management at Carnival Corporation, remarked: “The agreement reinforces Carnival Corporation’s ongoing commitment to operational excellence, sustainability and delivering a world-class guest experience. By working with Wärtsilä through a long-term lifecycle agreement, we can further strengthen the performance of the covered vessels while supporting the high standards our guests and operations depend on.”

Wärtsilä noted that the performance-based structure of the agreement aligns both parties around measurable operational outcomes, and that combining its role as original equipment manufacturer with digital solutions and global service capabilities will support the safe and efficient operation of Carnival Corporation’s dual-fuel engine assets.

Andrea Morgante, Vice President, Performance Services at Wärtsilä Marine, stated: “This agreement is the latest milestone in the long-standing relationship between Carnival Corporation and Wärtsilä. It reflects our shared focus on ensuring high-performing cruise operations through proactive lifecycle support, data-driven insight and close technical collaboration throughout the vessel lifecycle.”
