From Dry Dock to Deep Dive: The Technological Triumph Behind Mexico's Newest Navy Vessel

Eight years prior, Cocoon had crafted a pioneering solution in collaboration with Damen—a peelable variant of Cocoon designed to tackle the persistent issue of accretion on propeller shafts and blades, a notorious problem for ships before their inaugural trial run.

This innovation not only conserved resources but also drastically reduced the time needed to refurbish the screws.

On a brisk Monday, November 12, we found ourselves journeying back to Mexico, drawn once more to collaborate with Damen .

At that time, a patrol ship named ′Pola′ was under construction by the Mexican navy.

Positioned in the dry dock, Pola awaited technical clearance before it could grace the waters.

Yet, a familiar challenge loomed—a buildup of accretion on its propeller shafts and blades threatened to slow its trial run, echoing the very problem Cocoon aimed to solve.

Addressing this buildup was not only costly but time-consuming. Fortunately, eight years ago, Cocoon had been enlisted by Damen to devise a solution. Since then, Cocoon had applied their expertise on eight different vessels, spanning projects from Romania to Indonesia, and now Mexico.

With a significant time constraint overshadowing the project due to the impending inauguration of the ship by the president of Mexico, the pressure was palpable—the Pola had to be launch-ready on schedule.

To combat the accretion, we employed a peelable version of Cocoon on the propeller shafts, blades, and brackets. As the ship's components were finalized and it was nearly time to exit the dry dock, our team sprang into action.

We meticulously sprayed our over the critical areas, layering it to achieve the necessary thickness. This ensured that any accretion formed on the Cocoon layer, rather than directly on the ship.

Once launched, the ship bided its time until the trial run, shielded from any accretion by the innovative Cocoon. This safeguard saved considerable time and money.

When it was time for the ship to sail, a diver could simply cut away the peelable PVC, clearing the propellers effortlessly.

Moreover, Cocoon had already established its efficacy in preserving large components in open environments, yet this project showcased another facet of its versatility.

Applied underwater at depths of 5 to 6 meters, Cocoon not only had to be seamless and airtight but also waterproof. Even if it took one to two years for the ship to embark on its maiden voyage, Cocoon's protective layer stood guard against accretion at all times—demonstrating, conclusively, that it was also imperviously waterproof.
