ABSTRACT
This paper describes a program under the responsibility of LNEC for the systematic observation and monitoring of maritime works that has successfully been applied to a number of maritime structures on the Portuguese mainland coast. The now-called OSOM+ program comprises the following four main components for each structure: i) periodic visual inspections by an experienced technician; ii) periodic aerial inspections with a UAV/drone; iii) a ANOSOM-WEB 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; iv) a mobile, portable, application, for real-time input and visualization of the database information. OSOM+ has recently been updated with a number of tools and functionalities that are illustrated in this paper with applications to two real case studies: the Portim�o harbor breakwaters and Faro-Olh�o inlet entrance breakwaters, both located in the south coast of Portugal.

Keywords: Breakwater, Inlet, Harbour, Risk assessment.

RESUMO
Este artigo descreve um programa, sob responsabilidade do LNEC, de observa��o e monitoriza��o sistem�tica de obras mar�timas, denominado OSOM+, que tem sido aplicado com sucesso a v�rias estruturas mar�timas na costa continental portuguesa. O programa OSOM+ inclui as seguintes componentes principais, para cada estrutura: i) inspe��es visuais peri�dicas, com um t�cnico experiente; ii) inspe��es a�reas peri�dicas, com um VANT/drone; iii) uma base de dados ANOSOM-WEB, para armazenar e/ou consultar informa��es obtidas nas campanhas de observa��o, bem como para diagnosticar os estados atual, de evolu��o e de risco da estrutura; iv) uma aplica��o inform�tica m�vel, port�til, para preenchimento em tempo real e visualiza��o das informa��es da base de dados. Esta metodologia foi recentemente atualizada com uma s�rie de ferramentas e funcionalidades que s�o ilustradas neste documento com aplica��es a dois casos de estudo reais: os quebra-mares do porto de Portim�o e os quebra-mares da embocadura da barra de Faro-Olh�o, ambos na costa sul de Portugal.
