Cruise ships have long been a thorn in the side of environmentalists. They pollute the seas and disrupt the marine ecosystem. Because of this, one thing caused the explosives to explode again.

So were 800 passengers on Cruise ship Viking Orion sure didn’t fancy their vacation: Instead of visiting one place after another, they’ve recently had to stay on board for days. The luxury steamer has been banned from docking in Sydney Harbour. The reason for this is curious: apparently, the cruiser’s hull was covered with microorganisms, barnacles, mussels and algae.

Overgrown ship – what is biological pollution and what are the consequences?

This phenomenon is also known by the term “biopollution”. A viscous film usually forms here, for example when the ship has not sailed for a long time. This is the perfect breeding ground for unwanted microorganisms. The problem with this is not only that “sea growth” causes long-term damage to the ship, but also devastating effects on the delicate marine ecosystem may have.

When ships finally bring exotic creatures to other waters, native species are pushed out and new ones spread. Additionally, the added weight of biomass on the hull increases drag. As a result, the ship uses more fuel to move forward, which not only ends up costing the shipping company more, but also They also emit more emissions.

Cleaning, non-stick coating, regular driving. This helps with bio-pollution

The authorities in Australia and New Zealand did not want to take risks, which is why they gave the inflated luxurySteamers were forbidden to enter any of its ports. As a result, the cruise ship had to anchor 22 kilometers from the Australian coast in international waters. There it was cleaned by divers and eventually let go swamp in Sydney.

But it’s not harmful either: Depending on the cleaning technique, microorganisms can still get into the water and pollute the environment during the cleaning process. However, biopollution is an easy problem to fix. To prevent this from happening in the first place, there are already special non-stick coatings, called “anti-fouling paints,” that are applied to the outer skin of a ship’s hull. This and regular driving prevent organisms from settling.
