The campaign is part of Telemach’s initiative for a cleaner Adriatic “Happy Sea”, which the company launched in cooperation with the Digital Innovation HUB Innovamare association and the Ruđer Bošković Institute, and the Porat Krilo and Bajnice Association also provided its contribution and support to the campaign through cooperation with the Iglun Underwater Activities Club.

As part of a large underwater cleanup campaign in the Jesenice Wing last weekend, over 40 divers recovered three tons of waste with the help of Croatia’s first autonomous vessel and Telemach’s 5G network. The action was supported by the Municipality of Dugi Rat, the Tourist Board of the Municipality of Dugi Rat, and the students of the Jesenice Elementary School who contributed from the coast, by cleaning the beach and the Krilo harbor, as well as the children’s park. The campaign is part of Telemach’s initiative for a cleaner Adriatic “Happy Sea”, which the company launched in cooperation with the Digital Innovation HUB Innovamare association and the Ruđer Bošković Institute.
“This initiative shows how powerful a role technology plays in preserving our natural resources. “We are proud that, together with our partners, we are contributing to a sustainable future through the ‘Happy Sea’ project, and I am especially pleased with the exceptional interest of young people in participating in its construction,“ said Igor Duić, Director of Corporate Communications at Telemach.
Helping divers in precisely detecting underwater debris was the autonomous Faust V vessel, equipped with advanced sensors and an underwater drone adapted for depths of up to 50 meters, which transmitted images of the seabed in real time thanks to Telemach’s state-of-the-art 5G network and a sophisticated surveillance system.



“Although its applications are diverse, Faust V has proven to be an important partner in cleaning up the seabed. Its role in the ‘Happy Sea’ project is the best proof that innovation is not an option, but a necessity for achieving a greener future,” said Mateo Ivanac, President of DIH Innovamare.
In addition to contributing to the campaign by collecting waste on the beach and swimming area Krilo, students from Jesenice Elementary School had a unique opportunity to participate in sampling the sea and checking its quality. Under the expert supervision of lecturer Marin Lovrić from the Ruđer Bošković Institute, they learned about the process of analyzing seawater, thereby gaining important knowledge about the state of the environment.
“During the demonstration, we used a special surface sampling net called a plankton net. It extracts microscopic particles from the sea surface that are often not visible to the naked eye, but are found almost everywhere – in water, marine organisms, and even in sand. By sampling microplastics, we demonstrated a concrete method of environmental research and, I believe, further encouraged thinking about our impact on nature,” added Marin Lovrić, a lecturer at the Ruđer Bošković Institute.




The necessity of carrying out such clean-up actions in the Krilo Jesenice area was also emphasized by Teo Baučić, president of the Iglun Underwater Activities Club: “As a diver, every dive reveals to me the true state of our underwater world. Participating in actions such as ‘Happy Sea’ gives us the opportunity to take concrete action and contribute to the preservation of the sea. By using innovative technologies, we can spot and remove waste faster and more precisely, while at the same time educating children and young people about the importance of caring for the environment. This is not just a clean-up, but an important step towards long-term preservation of the sea and strengthening environmental awareness in society.”
Telemach’s first innovative environmental cleanup campaign, which puts the most modern technology at the service of environmental preservation, took place in April on Zadar’s Kolovare beach, where over a ton of waste was removed from the seabed.
