WG 233 – auscultation, maintenance et réparation des infrastructures maritimes et portuaires

The objectives of the Working Group (WG) will be to review, update and, where appropriate, expand or revise the existing pianc documenton this subject to reflect more recent references that are useful but not global in scope. In doing so, additional topics such as service life modelling, drone-based visual and laser inspection techniques, and the latest generation of non-destructive testing and repair technology will be added. In addition, various inspection types will be defined, with details of their purpose and scope of work clearly defined. Such inspection types will be defined by the Working Group, but may include:
• Routine Condition Assessment Inspections
• Baseline Inspections
• Repair Design Inspections
• Special Inspections (more in-depth, often conducted to define the “root cause” of observed deterioration)
• Post-Event Inspections

Post-Event Inspections are particularly important for waterfront structures. In the immediate aftermath of extreme events such as earthquakes, tsunamis, severe storms and vessel impact, there can be uncertainty whether significant damage has occurred to port infrastructure, and consequently whether full or limited operations can safely resume before investigation and repairs are undertaken.
Where impact is widespread, there is often limited availability of the required expertise (if not available in-house) to undertake assessments of the infrastructure, increasing the impact on operations.
The outcome of this report should be usable for maritime ports and terminals, inland waterway facilities and big ship marinas.
