Designed for Collisions: Secret of the Crimea Bridge to Resist Possible Attacks

CRIMEA, Russia – The Crimean Bridge was specially equipped with two deep water pillars with structures that would protect it from possible collisions with ships.

“At the end of the year, the construction of special structures and bollards for deep-water abutments has been completed. In case of emergency aboard a ship traveling through the Kerch-Yenikale canal, they will help protect the ship and pillars,” reads the bridge builders’ press release.

The mooring posts are made up of submerged steel pipes at a depth of 29 meters and filled with heavy hydraulic engineering concrete.

In addition, the mooring posts and the two deep-water pillars are equipped with rubber baffles. The outer poles, with a diameter of 18 meters, have signaling lights.

The bridge design was specially developed based on the results of mathematical models of a possible collision of ships.

If there is a failure in the vessel control system, it is ensured that the vessels safely cross the arched section of the bridge, since the minimum space between the side of the vessel and the pillars is 30 meters.

The structure has a four lane road with flow capacity of up to 40 thousand vehicles per day and two railway lines.

The Crimean Bridge across the Kerch Strait, linking the Crimean peninsula to the Russian region of Krasnodar, is the longest in Russia at 19 kilometers long. The bridge’s inauguration was initially set for December 2018, but builders completed work in advance, inaugurating the bridge for automobiles in May.

Arkadi Rotenberg also said that the construction of the bridge involves about eight thousand workers and that everything is happening within the foreseen period. For the construction of the bridge, a budget of 227.9 billion rubles, or 14 billion reals, was estimated.

“I believe that it will last for 100 years, I am quite sure of this since many scientific institutes have been working on construction, calculating and measuring everything. If the bridge suffers some kind of earthquake or movement, the pillars are fixed in such a way and at different angles that nothing would happen, and the bridge will remain firm,” Rotenberg told Rossiya channel 1.
