Carnival Corp is to roll out a comprehensive package of technology upgrades, dubbed ‘Service Power Packages’ across its fleet.

The aim is to further improve energy savings and reduce fuel consumption, the company said.

Upgrades include ongoing installations through 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.

The service power upgrade programme delivers an average of 5-10% fuel savings per ship and is expected to reduce fleetwide greenhouse gas emissions by more than 500,000 tonnes per year.

In addition to the environmental benefits, upon completion, the programme is expected to generate over $150 mill in annual fuel cost savings, Carnival claimed.

Developed during the past six years, the programme delivers significant efficiency enhancements across the fleet, including air conditioning upgrades to cabin and public areas, and major improvements to cooling, lighting and automation systems.

Adjusting for variations in ship design, size and equipment, the company customises the package for each ship, which combines the synergies from multiple upgrades with new operational efficiencies, all effectively supporting Carnival Corp’s energy savings and de-carbonisation strategies, the company explained.

The packages include the following elements designed to work together to reduce each ship’s overall service load – the energy required to support all on board hotel systems – and as a result, significantly reduce both fuel usage and emissions:

  • Comprehensive upgrades to each ship’s hotel HVAC systems – accounts for 25% of a ship’s energy consumption. Improve hotel ventilation efficiency using sophisticated variable speed drives and on-demand systems throughout public areas, cabins and galleys. In addition, indoor air quality is continuously monitored and maintained to the highest standards at sea, using an air filtration and ultraviolet-C treatment throughout the ship.
  • Technical systems upgrades on each ship – variable speed drives and on demand automated control systems for engine room ventilation, main air conditioning chillers and cooling pumps will be used, which together dramatically lower the energy needed to deliver cooling around the ship.
  • LED lighting systems – installed throughout each ship to reduce both power consumption and heat load generation – creating a dual benefit from lower air conditioning demand.
  • Remote monitoring and maintenance – improvements that maximise benefits from the upgrade packages, including improved instrumentation and automated management systems, with non-stop ship-to-shore connectivity. Expanded remote monitoring and analysis of each ship’s energy performance and technical status ensure peak efficiency and minimal down times.

“The Service Power programme closely aligns with our long-term sustainability and de-carbonisation goals and our highest responsibility and top priority, which is compliance, environmental protection and the health, safety and well-being of our guests, the people in the communities we visit, and our shipboard and shoreside personnel,” said Bill Burke, Carnival Corp’s Chief Maritime Officer (pictured).

“Based on our improved fleet composition, including adding six industry-leading LNG-powered ships, and our previous investments to increase efficiency and reduce emissions, our absolute carbon emissions peaked in 2011, despite significant capacity growth over the past decade. These tailored ‘Service Power Packages’ further build on those efforts as part of our comprehensive approach to sustainability,” he added.

Fleetwide enhancements are part of Carnival Corp’s ongoing energy efficiency investment programme and efforts to reduce fuel consumption, including over $350 mill invested in energy efficiency improvements since 2016, along with the company’s fleet optimisation strategy and design of more efficient itineraries.

Together, these ongoing efforts are expected to drive a 10% reduction in fuel consumption per available lower berth day (ALBD) in the company’s first full year of guest cruise operations, compared to 2019, along with a 9% reduction in carbon emissions per lower berth distance travelled.

As part of its longer-term sustainability plan and vision, the company said that it had committed to significant investments to achieve its 2030 sustainability goals and 2050 aspirations, which incorporate six critical sustainability focus areas overall – climate action; circular economy; sustainable tourism; good health and well-being; diversity, equity and inclusion; and biodiversity and conservation.

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