Carnival Corp Leans on Tech to Boost Vessel Efficiency, Cut Emissions

Carnival Corporation & plc (NYSE/LSE: CCL; NYSE: CUK), the world's largest cruise company, is advancing greater fuel efficiency for propulsion through hull designs and new hardware and technology, along with underwater drone inspection and cleaning trials.

This work is done through complementary strategies focused on maximizing hydrodynamic performance and enhancing ongoing hull maintenance, which reduces a ship’s underwater drag.

Here's a synopsis of the CCL strategy:

• Hull Designs: When selecting the optimal hull design, computer-assisted analysis enables ship and propeller designers to run hundreds of thousands of simulations, identifying the best design options for different sailing conditions.
• Trim Optimization: Software is used onboard to optimize the trim of a vessel by transferring ballast water internally to ensure that the ship operates continuously in the best configuration for propulsive efficiency.
• Podded Propellers: Over 40 ships in the company’s fleet are fitted with high-efficiency, 360-degree steerable propulsion units up to ~7% more efficient than conventional propellers. This number will continue to grow as new ships with this technology are added to the fleet.
• Air Lubrication Systems (ALS): More than 10% of the company’s fleet is already equipped with
