The dredging works of 31.82 m.3 has been completed by using more man ten of trailed suction hopper dredge with which are in hopper capacity from 6500,4500 to 2000m3. By the end of March, 2000, the depth has been reached up to the required -8.5m navigable depth. This paper gives a presentation of the process, problems and measures taken and some lessons and experience drawn from the execution of the works. About the authors:
