World’s Largest Cruise Company Turns to Air Bubbles to Help Reduce Emissions

The world’s largest cruise shipping company has announced plans to install air lubrication technology on at least 20% of its fleet.

Carnival Corporation says the Air Lubrication Systems (ALS), which are already in use aboard four ships, will be added to five more ships this year with plans to install the technology on at least 10 more ships across a majority of its brands through 2027.

The hull drag-reducing technology is expected to reduce fuel consumption and carbon emissions by about 5% per ship, according to the company.

ALS technology, which first saw service within the Carnival Corporation fleet in 2016 with the introduction of AIDAprima, generates a cushion of air bubbles to lubricate the flat bottom of a ship’s hull, reducing friction between the ship and surrounding water, resulting in savings in energy and fuel consumption across a wide speed range.

Carnival Corporation is currently installing the Silverstream® System ALS on five more ships, including two ships in 2022 for its Princess Cruises and P&O Cruises (UK) brands. In addition, the company is planning at least 10 more installations for existing and newbuild ships across more than half of its cruise line brands, and it expects continued expansion of the ALS program. The expansion plans build on the success of four systems currently operating on ships from its AIDA Cruises and Princess Cruises brands.

“The installation of air lubrication technology is another example of our ongoing efforts to drive energy efficiency and reduce fuel consumption and emissions throughout our fleet,” said Bill Burke, chief maritime officer for Carnival Corporation. “We look forward to expanding the ALS program and furthering our long-term sustainability strategy to continually invest in a broad range of energy reduction initiatives, which has included over $350 million invested in energy efficiency improvements since 2016.”

Carnival Corporation has committed to reducing carbon emission intensity by 20% from its 2019 baseline by 2030 and has set an aspiration to achieve net carbon-neutral ship operations by 2050.

AIDAprima Completes Bio-Bunkering in Partnership with GoodFuel

GoodFuels partnered with Carnival Corporation’s AIDA Cruises and completed the first bio-bunkering on AIDAprima, according to a press release.

The AIDAprima was refuelled with GoodFuels’ sustainable biofuels during a port visit to Rotterdam, in the Netherlands as part of a seven-day cruise, visiting Hamburg, Southampton, Le Havre, and Zeebrugge, according to the company. Without requiring any engine or tank modifications, AIDAprima was bunkered with biofuel and continued its itineraries.

“With the successful start of biofuel usage, we have proven that gradual decarbonization is possible even on ships already in service. An important prerequisite for us as a cruise line to be able to use it is that it becomes widely available on an industrial scale and at marketable prices,” commented Felix Eichhorn, president, of AIDA Cruises.

The recent bio-bunkering appears to be just the beginning, as AIDA expects additional deliveries and a possible expansion to other Carnival Corporation brands.

 “This first bio-bunkering with AIDA Cruises marks an exciting step forward on the cruise industry’s decarbonisation pathway, demonstrating that our sustainable biofuels are a safe, technically viable and convenient option to drastically cut down emissions from passenger’s vessels. As the effects of climate change are felt acutely in several parts of the world, the time for action is now, and biofuels are one of the few options that can already make a difference today. We are delighted to have worked alongside the trail-blazers at AIDA Cruises in the past few months to make this milestone a reality, and we look forward to collaborating again in the future,” said Dirk Kronemeijer, chief executive officer, GoodFuels.

AIDA Cruises will sponsor the 833rd-anniversary celebrations for the Port of Hamburg, taking place from Sept. 16 to 18, 2022.

The main attraction on the water will be AIDAprima on Saturday evening, Sept. 17, 2022: As the finale of the birthday party, the AIDAprima will provide a light show in the heart of the city.

“We are delighted to be the sponsor of Hafengeburtstag Hamburg for the ninth time, the largest maritime event in northern Germany with over a million visitors,” commented Alexander Ewig, senior vice president of marketing and sales for AIDA, in a prepared statement.

During the three-day event, those interested in cruising can find inspiration for their next dream vacation aboard an AIDA ship at a cruise line store set up in the port. Among the features, visitors will be able to see a replica AIDAcosma cabin. There will also be a large roof terrace with lounge chairs, along with AIDA travel consultants to provide information.

By 2022, nine AIDA ships will make 120 calls in Hamburg, The AIDAsol kicked off the nearly 12-month season on Jan. 7, 2022, and the AIDAprima will conclude the year on Dec. 29, 2022.
