Abandonment of Ships and Irregular Dismantling Aggravate Environmental Damage and Threaten Security in Coastal Waters in Brazil and Worldwide

The increase in so-called ship graveyards generates great concern around the world. In many cases, the dismantling of these vessels occurs in poorer countries, where labor is cheaper and effective environmental regulation is lacking.

The dismantling of cargo and passenger ships already reaches about 1,200 vessels per year. This process requires specific technology and equipment to minimize damage to the marine and coastal environment.

Abandoned Ships: An Invisible Threat

The biggest problem is the abandonment of ships in coastal waters. In these areas, juvenile marine life develops more intensely. Chemicals released by abandoned ships critically affect the juvenile biota, which is extremely sensitive.

Environmental Damage and Navigation Risks

Over time, the hulls of vessels deteriorate, releasing an abundance of chemicals and ferrous materials. This contamination harms marine fauna and flora and can take years to reverse.

The sinking of these hulls compromises the water exchange in bays and estuaries. Furthermore, these structures become dangerous traps for maritime transport, affecting navigation safety.

Unsafe Dismantling Aggravates the Problem of Abandoned Ships

Another critical point is the dismantling of ships done without the proper techniques and equipment. Many serious accidents, including deaths and permanent disabilities of workers, are reported.

These precarious dismantlings cause leaks of fuels, oils, corrosive products, and cargo residues. The contamination aggressively affects fragile coastal areas, potentially destroying ecosystems that have formed over centuries.

Materials such as iron, plastics, and petroleum derivatives become long-lasting pollutants. Elements like lead, cadmium, mercury, and nickel are just a few examples of heavy metals found. In addition, asbestos, paint residues, and toxic vapors also appear.

Critical Situation in Brazil

In Brazil, the abandonment of end-of-life ships continues to be a particularly visible problem in large bays. Examples include Guanabara Bay, All Saints Bay, Paranaguá Bay, and Santos and São Vicente Bay.

In 2025, in Guanabara Bay alone, more than 60 hulls of large ships have already been identified. Besides these, numerous fishing, recreational, and small transport boats are also abandoned or sunk.

Now that we understand the risks that abandoned ships pose, society must demand immediate action for the proper demobilization of these vessels.

Responsible entities must act with qualified technicians to create efficient policies and strategies. The goal should be to ensure the safe and environmentally responsible dismantling of end-of-life ships.

The protection of the marine environment depends on the joint efforts of civil society, governments, and specialized institutions.

Critical Situation in Brazil

While an average building in London or New York takes three years to be completed, in China a 26-story tower went up in five days with about 100 workers, and the global modular construction market already moves US$ 95 billion per year.

Australia installs giant concrete structures on the seabed 800 meters from the shore to create an ocean intake for desalination that will draw in saltwater and produce 30 million liters of drinking water per day.

A public school student single-handedly created a machine capable of treating water for up to 50 people using only solar energy. It was awarded third place at one of the most important science fairs in the world.

Goodbye traditional washing machine: Panasonic surprises housewives with the NA-G5 featuring four drums, a 13 kg washer and dryer, a 12 kg dryer, independent mini washers, a heat pump, and a 4-in-1 system awarded at the German Design Award.

While cities spend fortunes patching potholes and tons of plastic become waste, the Netherlands transforms over 218,000 recycled cups into a modular bike path that can conceal drainage, cables, and pipes.

While communities suffer from water scarcity and the advancing desert, women in Morocco use nets high up in the mountains to trap fog droplets, fill reservoirs, and transport drinking water through more than 10 km of piping.

An illiterate bricklayer invented the plate cistern that stores 16,000 liters of rainwater and serves a family for eight months in the sertão, an invention that became the basis of the One Million Cisterns Program in the Brazilian Northeast.

A building that looks like an inverted ship draws attention in São Paulo: the Hotel Unique, with 84 meters, round windows, exposed concrete, and a red pool on top.
