T he summer season in Greece brings with it particularly intense weather conditions.

Consequently, construction companies and port funds are now planning the necessary port expansions and deepenings. However, the dredging of ports with explosives is an extremely complex and specialized process. The work requires absolute precision, special equipment and a deep knowledge of the dynamics of underwater explosions.

EXORIXI S.A., with over 35 years of experience in iconic port projects, presents the critical technical data for the safe execution of these works.

The peculiarity of underwater blasting

The use of explosives under water is fundamentally different from land-based applications. In particular, the hydrostatic pressure and the presence of water alter the behavior of the blast wave. However, our company's engineers apply special safety protocols.

For these projects, we use exclusively watertight, waterproof, high-performance explosive emulsions. In addition, the design of micro-firing timings ensures the efficiency of the excavation. In this way, we achieve optimal fragmentation of the solid rock at the bottom. At the same time, we minimize unwanted underwater shock waves.

Protection of existing port infrastructure

The main challenge in an active port is the protection of adjacent structures. Piers, quay walls and passing ships must remain completely intact. Therefore, vibration monitoring is imperative.

We install special, waterproof seismographs at strategic points on the coastline and on existing piers. In this way, we control the ground shock waves in real time. Thus, we ensure that the works do not affect the statics and safety of the port. Finally, EXORYXI S.A. provides valid reports of compliance with the strictest international safety standards.

Frequently Asked Questions (FAQ)

What are the main difficulties in explosive dredging?

Dealing with hydrostatic pressure at depth, ensuring the tightness of explosives and protecting existing port infrastructure are the biggest challenges.

How are piers protected from underwater blasts?

We install specialized sealed vibrographs for real-time monitoring of vibrations. AlsoWe design the firing with micro-timings to drastically reduce the intensity of vibrations.

Is it safe to use explosives at sea?

Yes, as long as certified organizations study and execute the project with strict protocols. EXORIXI S.A.has the necessary experience and equipment to guarantee safety.
