The Xblocs® are positioned on the overall structure of the breakwater by the Design and Construction Joint Venture to break the power of the waves and resist to sea rising level in the next hundred years. Their implementation is tricky and must comply with detailed specifications to ensure the breakwater long-term durability in accordance with the contract requirements.
Calais Port 2015 Xblocs® weight ranges from 10 to 30 tons. After having being dried on the production site during the time required, they are dispatched on the breakwater and immediately placed by the PosiblocTM system and the Echoscopeâ allowing their geo-tracking and preview in 3D, even under water. DMC Company (Delta Marine Consultants), holder of the Xblocs® patent, confirms if the Xblocsâ are properly arranged, if so delivers an approval allowing the next implementation by the Design and Construction Joint Venture.
The Hitachi EX1900, a crane of an exceptional size weighing 280 tons is now available on the works site to position the biggest Xblocs® on the westernmost part of the breakwater.
