Carnival launches energy-saving technology

SINGAPORE, 8 August 2022: Carnival Corporation & plc, the world’s largest cruise company, has announced the deployment of comprehensive technology upgrades called Service Power Packages across its global fleet to improve energy savings and reduce fuel consumption.

The upgrades include ongoing installations until 2023 on ships from the company’s nine cruise line brands – Carnival Cruise Line, Princess Cruises, Holland America Line, Seabourn, P&O Cruises (Australia), Costa Cruises, AIDA Cruises, P&O Cruises (UK) and Cunard .

Carnival Corporation’s Service Power upgrade program delivers an average of 5-10% fuel savings per ship and is expected to reduce fleet-wide greenhouse gas emissions by more than 500,000 metric tons each year. In addition to the environmental benefits, upon completion the program is expected to generate over US$150 million in annual fuel cost savings.

Developed over the past six years, the company’s Service Power program delivers significant efficiency improvements across the fleet, including improvements to air conditioning in the cabin and public areas and major upgrades to cooling, lighting and automation systems. Adapting to variations in ship design, size and equipment, the company customizes a Service Power Package for each ship that combines the synergy of multiple upgrades with new operational efficiencies, all of which effectively support Carnival Corporation’s energy conservation and decarbonization strategies.

Carnival Corporation’s service power packages include the following items designed to work together to reduce each ship’s overall load – the energy required to support all onboard hotel systems – and as a result significantly reduce both fuel consumption and emissions:

Comprehensive upgrades to the hotel HVAC systems on each ship account for 25% of the ship’s energy use to improve the hotel’s ventilation efficiency, using sophisticated variable speed drives and on-demand systems in public areas, staterooms and galleys. In addition, indoor air quality is continuously monitored and maintained to the highest standards at sea, using industry-leading air filtration and UV treatment throughout the ship.

Upgrades to each ship’s technical systems using variable speed drives and automated on-demand control systems for engine room ventilation, main air-conditioning chillers and cooling pumps, dramatically reducing the energy required to deliver cooling around the ship.

State-of-the-art LED lighting systems are installed in each vessel to reduce both energy consumption and heat load generation – creating the dual benefit of lower air conditioning demand.

Improvements in remote monitoring and maintenance maximize the benefits of upgrade packages, including improved instrumentation and automated control systems, with seamless ship-to-shore connectivity. Advanced remote monitoring and analysis of each vessel’s energy performance and technical status ensure maximum efficiency and minimum downtime.

The fleet-wide improvements are part of Carnival Corporation’s ongoing energy efficiency investment program and efforts to reduce fuel consumption, including more than $350 million invested in energy efficiency improvements since 2016, along with the company’s optimization strategy of the fleet and the design of more efficient routes. Together, these ongoing efforts are expected to result in a 10% reduction in Available Bottom Day (ALBD) fuel consumption in the company’s first full year of guest cruise operations compared to 2019, along with a 9% reduction in carbon emissions for lower anchor day distance traveled.

As part of its long-term sustainability plan and vision, Carnival Corporation has committed to significant investments to achieve its 2030 goals and 2050 aspirations, which include six critical sustainability focus areas. These areas include climate action; circular economy; sustainable tourism; good health and well-being, diversity, equality and inclusion, and biodiversity and conservation.

Among these priorities, the company has committed to reduce carbon intensity by 20% from its baseline from 2019 to 2030, supporting its efforts and aspirations to achieve net carbon-neutral shipping operations by 2050.
