Abstract:
This paper describes a programme under the responsibility of LNEC for the systematic observation and monitoring of maritime works, termed OSOM+, that has successfully been applied to an extensive number of maritime structures on the Portuguese mainland coast and abroad.
The OSOM+ programme comprises the following four main components for each structure:
Periodic visual inspections by a trained technician;
Periodic aerial inspections with a UAV/drone;
The ANOSOM-GIS database, to store and/or query obtained information, as well as to diagnose present, evolution and risk conditions;
A mobile, portable, application, for real-time input and visualization of the database information.
This recently updated methodology encompasses a number of tools and functionalities that are illustrated in this paper with applications to a real case scenario, the Ericeira’s breakwater, in Portugal.
