Carnival introduces energy-saving technology

SINGAPORE, August 8, 2022: Carnival Corporation & plc, the world’s largest cruise line, has announced the introduction 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 through 2023 on ships across the company’s nine cruise 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 tons each year. In addition to the environmental benefits, the program is expected to generate over $150 million in annual fuel cost savings upon completion.

The company’s Service Power program, developed over the past six years, delivers significant efficiency improvements across the fleet, including air conditioning upgrades for the cabin and public areas, as well as significant upgrades to cooling, lighting and automation systems. Adapting to variations in ship design, size and equipment, the company customizes the Service Power Package for each ship, combining the synergies of multiple upgrades with new operational efficiencies and effectively supporting Carnival Corporation’s energy conservation and decarbonization strategies.

Carnival Corporation’s Service Power Packages include the following elements designed to work together to reduce each ship’s overall service load — the energy required to support all onboard hotel systems — and as a result, reduce both fuel consumption and fuel consumption significantly reduce emissions:

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

The engineering systems are upgraded on each ship with variable speed drives and on-demand automated control systems for engine room ventilation, main air conditioning radiators and cooling pumps, dramatically reducing the energy requirements for cooling around the ship.

State-of-the-art LED lighting systems are installed on each vessel to reduce both power consumption and heat load – giving the double benefit of reduced need for air conditioning.

Remote monitoring and maintenance improvements maximize the benefits of the upgrade packages, including improved instrumentation and automated management systems with non-stop ship-to-shore connectivity. Advanced remote monitoring and analysis of each vessel’s energy performance and technical condition ensures maximum efficiency and minimum downtime.

The fleet-wide improvements are part of Carnival Corporation’s ongoing energy efficiency investment program and fuel economy efforts, including over $350 million invested in energy efficiency improvements since 2016, along with the company’s fleet optimization strategy and designing more efficient itineraries. Taken together, these ongoing efforts are expected to result in a 10% reduction in fuel burn per lower berth available day (ALBD) as well as a 9% reduction in CO2 emissions per lower berth in the Company’s first full year of guest cruise operations compared to 2019 % distance traveled.

As part of its longer-term sustainability plan and vision, Carnival Corporation has committed to significant investments to meet its 2030 Goals and 2050 Aspirations, which encompass six critical sustainability focus areas. These areas include climate protection; circular economy; sustainable tourism; good health and well-being; diversity, equity and inclusion; and biodiversity and conservation.

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