Nautec has completed its grouting of pipeline crossings and freespans for Mumbai High South Redevelopment Phase III project (MHSRD-III). Nautec was awarded the contract by Kreutz Subsea Pte Ltd.

Nautec provided grout bags and grouting services for the installation of crossings and freespan pipeline support. The crossing support and grout bag installation work was carried out utilising a Kreuz Installer (KI).

The grouting team used Nautec’s range of high performance cement (HPC) NaX Q80. The HPC materials are designed to meet the special demands of very high and long-distance flows and rapid strength development reaching more than 50 MPa in 24 hours (at 25 deg C).

These special features allowed for the grout bags to be lifted and moved to other locations underwater much faster than if a conventional cementitious product had been applied.

The project was completed ahead of schedule and to client satisfaction.
