Croatian Innovation to Aid Nautical Companies in Dealing With Waves

Branimir Jurun and his wave measuring device could potentially take the nautical world by storm.

As Poslovni Dnevnik/Ana Maria Filipovic Grcic writes on the 13th of May, 2018, Branimir Jurun, a student about whom we have previously written, from the Dalmatian capital of Split, has recently managed to gain quite the name for himself among university circles, thanks to his innovative measuring device, Quattuor 45, of which he is the sole creator.

In a conversation with the young innovator himself, Poslovni Dnevnik learned that the Quattuor 45 application is suitable anywhere in the coastal area where the effects of sea waves are of significant importance.

“At the first year of the faculty, we learned that the characteristics of the inclination (tilt/slope) of the beach and the pressure of the wave result from the size of the stones/pebbles found on a natural beach. At that point, I figured out how these three variables can be classified into a mathematical relation in some way. Two variables are very easy to determine, while one variable, wave power, was unknown. Then the idea of ​​a wave measuring instrument came up,” Jurun told Poslovni Dnevnik.

By studying wave movements, the breaking of the waves, the height and size of the waves above the existing sea level, wave effects on sea sediments and on marine installations, Jurun says that he has somewhat eliminated the drawbacks of the sketches of one of the first variants of the instrument, and by the end of 2016, the first official version came to fruition.

In the realisation of this project, he added, not only family and friends, but also faculty professors and colleagues who advised and wrote up a student project so that the University of Split could co-finance the development of the instrument all helped things along. So far, the University has obtained about 35,000 kuna for that purpose.

Jurun explained that the plan is to synchronise the instrument with mobile devices and software devices so that wave and wind speed data can be accessed by all to whom it is relevant. For example, prior to setting sail, a nautical shipping company will be able read nautical parameters essential for the ship on the computer. For commercial seaports, such a synchronised data system would greatly boost overall service quality.

The innovative Split student also wrote up a scientific paper with data on the measurement of sea wave pressure, and back in 2017, he participated at the Water Technology conference in Zurich, Switzerland.

“In March, I participated in the World Conference for the second time, now in Prague,” he added. Jurun rightly says that the most important thing for those chasing their own success is to fully believe in their ideas and not to give up on their eventual realisation.

“The beginnings are extremely tough in what I’ve come across through student life. My plan is to continue in the same direction and to further contribute to the development of society,” concluded the talented Jurun.
