Quality port infrastructure is a prerequisite for the development of trade, which is a factor in human and social development. STUDI offers a wide range of services for the design and supervision of works for commercial, fishing, pleasure and other coastal and coastal protection projects. STUDI acts both on behalf of governments and private investors by taking these port infrastructures into account in their economic and geographical environment. Our references include projects in some fifteen countries each with diverse and complex problems, including bathymetry, dredging and financing, in addition to the structures themselves (docks, ears, embankments, dikes).
