Objectives/scope The control of monolayer concrete armour units on coastal protection breakwaters can be time and cost consuming, especially underwater. It is even more the case when - for maintenance and control purpose - they are conducted long after the completion of the construction (positioning issues, number of units to control, etc). However, this occurs frequently on construction projects which last for several years, or during the operation and maintenance of such structures. On top of that, the complexity of this type of projects - usually coastal constructions such a dike easily exceeds 6000 units/km - requires precision and productivity for the control inspections. As a result, specific control solutions have been developed on the NRL project to inspect and monitor the breakwater after its construction. |
