Recent advances in LNEC´s monitoring of maritime works in Portugal

Abstract

This paper describes a programme under the responsibility of LNEC for the systematic observation and monitoring of maritime works that has successfully been applied to an extensive number of maritime structures on the Portuguese mainland coast and abroad. The now-called OSOM+ programme comprises the following four main components for each structure: periodic visual inspections by an experienced technician; periodic aerial inspections with a UAV/drone; a ANOSOM-GIS database, to store and/or query obtained information on the observation campaigns, as well as to diagnose present, evolution and risk conditions of the structure; 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, the Faro-Olhão’s entrance breakwaters, in the south coast of Portugal.
