Carnival opts for Wärtsilä waste treatment on 32 ships across brands

Technology group Wärtsilä has signed a framework agreement with Carnival Corporation, the global cruise ship operator, covering the supply and installation of Wärtsilä’s advanced wastewater and dry waste treatment systems for up to 32 vessels across many of its operating brands. The framework is consistent with Carnival’s policies for compliance with the latest and most stringent environmental legislation.

Wärtsilä’s Membrane Bioreactor wastewater treatment plants are well proven in the handling of black and grey wastewater. The system surpasses the most demanding standards currently set by the International Maritime Organization (IMO) for sewage discharge, including paragraph 4.2 of MEPC 227 (64), which applies to special areas.

Similarly, Wärtsilä’s dry waste handling systems comply with the most stringent IMO Marpol requirements, and are designed to minimise greenhouse gas emissions. Wärtsilä’s advanced technologies and vast experience were cited as being major considerations in the award of this contract.

“There is increased awareness within the cruise industry of environmental sustainability, and Wärtsilä is proud and ready to support this focus with the most advanced and compliant solutions. We continue to work with Carnival to enhance their goals for waste reduction, in line with their internal strategy,” said Arto Lehtinen, Director at Wärtsilä Water and Waste.

“We very much appreciate Wärtsilä’s support and their capabilities in delivering high quality, reliable solutions tailored to our specific requirements. The environmental legislation barrier for the cruise industry is set very high, so we seek the latest technologies to ensure compliance. The Wärtsilä solution selected for the framework more than meets this standard,” said Jon McKeown, Senior Vice President global strategic sourcing from Carnival Corporation.

The Wärtsilä equipment will be delivered and installed onboard different ships across many of the operating brands through to 2025.
