1. HYDRANTULA technology has been developed taking with maximum possible reduction of «wet» works - driving piles into the seabed, work from barges, welding and installation work above water; diving, etc. These categories of work always carry increased risks for employees. They require higher qualifications and work discipline. 2. Unlike other types of marine construction technologies, there is no «strong» connection of the building structure with the seabed - it «just stands» at the bottom. The structure «as is» could be removed entirely without destroying it (although it is expensive). As you know, one of the main difficulties in marine construction is the impossibility or incredible complexity of demolishing outdated SUSTAINABLE DEVELOPMENT WITH HYDRANTULA

or worn-out marine structures by breaking them into pieces and removing parts to shore. This makes our products environmentally responsible; ensuring the sustainable development of water areas. 3.The carbon footprint and environmental damage from construction projects largely depends on their material consumption. Hydrantula provides savings of up to 75% of concrete and 45% of reinforcement compared to traditional shore protection and mooring facilities. Hydrantula construction materials require much less energy, which means less coal or other fossil fuels in comparison with alternative technologies (sheet piling, retaining walls, pontoons) 4. Short-lived materials such as wood and ferrous metals are popular in marine construction. This reduces the life cycle of a berth, seawall or wet

garage to 15-20 years. At the same time, the intensive use of heavy construction machinery (= huge consumption of diesel) negates the effect of using «green» wood.The total cost of ownership (before wear) and the total carbon footprint of Hydrantula are much lower! 5. There is a misconception that any plastic in the water eventually turns into a «microplastic». That’s not true! About 88% of all microplastics are coming from fishing nets and fibrous materials. Another 10% are thin films: packing from supermarkets and so on. The remaining 2% are thin plastic bottles (Pepsi) and disposable tableware. The key factor in the formation of microplastics is its initial shape - the fibers produce 100 times more microplastics than thin films of equal weight, and films are 100 times worse than «thick» items. Therefore, although the weights of lost fishing nets is almost 10,000 times less than the weight of discarded plastic packaging - the fibers from fishery nets are responsible for 88% of microplastics in

the world’s oceans. Second factor - abrasion of floating items -several times more dangerous. «Bottom» (not floating) plastic - generate just sand. Massive, non-floating plastic products do not generate microplastics. 6. More and more communities are realizing that global warming and the associated sea level rise [SLR]; the increasing strength of winds and waves is shifting the balance in coastal areas. Beaches are being washed away, shore erosion and flooding are common now! It is no longer possible to ignore these processes. Urgent measures are needed to stabilize the coastline, protect it against storms and flooding. Traditional methods - RipRap, Reno mattresses, tetrapods - are very expensive and turn beach into a strip of barriers and obstacles. These technologies save real estate in the first line, but ruin its value. Hydrantula technologies ensure not only the protection of the coast, but also the preservation and development of its recreational potential. Improve the accessibility of coastlines.

7. About 13% of the world’s area is shallow waters up to 12 meters deep. This is only 2 times less than Continents of the Earth (27%). The vast majority of this aquatoria is located in climatically favorable areas. And at least 30% adjoins economically developed areas of Europe, USA, China, Middle East, Indonesia and Australia.The development of this aquatoria can provide affordable, attractive and environmentally friendly housing and jobs for 2 billion people. 8. Hydrantula can greatly boost development of marine farms in shallow cold seas.
