(1) Núcleo
The Laboratório Nacional de Engenharia Civil (LNEC – the Portuguese Civil Engineering Laboratory) is a public
institution of science and technology, covering the broad field of civil engineering.
The Hydraulics Department started its activities in 1948, two years after LNEC was created, and includes the
Harbours and Maritime Structures Division (NPE, its Portuguese acronym) which is responsible at LNEC for the
research in the area of Port Engineering.
NPE activity consists of applied research and research under contract in the fields of design, safety and exploitation
of maritime works, particularly harbours, port structures, underwater structures and coastal defense structures. It
must be pointed out that almost all the maritime structures designed in Portugal were tested through scale models
built in the wave basins and / or the wave flumes of LNEC.
Up to the present, NPE has performed more than two hundred research studies under contract, of which about fifty
for foreign clients, in Europe, Asia, Africa and South America. Those studies comprised:
•
•
•
•
stability and overtopping tests;
wave disturbance tests;
pressure tests;
wave energy power plants scale model tests.
his paper aims to make a brief description of the division history which is followed by the description of some of the
most relevant studies under contract performed by LNEC during the last five years in the field of physical modelling,
as well as recent methodologies applied to scale modelling damage assessment, as photogrammetry and remote
access to experimental facilities (Figures 1 and 2).
