Ports and Coastal Infrastructure

Menard Oceania’s years of experience, range of activities and ownership of equipment in-house, allows us to provide solutions to many problems associated with Ports and Coastal Infrastructure.

Quays, jetties

Infrastructure built on the coast often require complex geotechnical works. Permanent prestressed anchors, caissons, caissons lying on underwater stone columns, jet grouting stabilisation… all techniques in the Menard Oceania range of skills acquired over several decades of involvement in large international projects.

Reclamation and seabed improvements

Construction projects at ports generally involve vast areas of land, either reclaimed or natural deposits. Treatment objectives can range from retention systems, settlement control and increased bearing capacity, to liquefaction prevention against seismic events. Often reclaimed land lies over wetlands which are recovered using dredged or imported fill materials. The resulting areas of reclaimed land frequently present challenges to the designer to identify economical means of improving such large areas of land. The designer’s primary objective is to induce a soil treatment which stabilises the fill for short-term and long-term performance in the most cost-effective manner. Menard Oceania provides the methods combined with experience to address this objective.

Marine structure remediation

Remediation of quay and marine structures is often complex, but provides a cost-effective way to maintain a port‘s activity at full capacity. Menard Oceania’s years of experience, range of activities and ownership of equipment in-house, enables it to provide solutions to many problems associated with long-term settlement, erosion and corrosion of retaining structures that are present in existing port and jetty facilities. Global warming and associated rise in sea level create an ever increasing requirement for coastal and offshore infrastructure maintenance.
