Grouting Installation Services
Nautec’s offshore installation grouting services are based on the application of Ordinary Portland Cement (OPC) or High Performance Cementitious (HPC, NaX Q80™ and NaX™ Q110) grouts. Nautec operates custom-built grouting equipment using computerised or PLC controlled batch mixing technology to ensure accurate grout feeding either from offshore certified storage silos or FIBC jumbo bags. Nautec’s grouting spreads are all configured with 100% redundancy and can be delivered with capacities in excess of 40 metric tonne per hour.
The use of HPC grouts significantly reduces the risk of leakage, eliminates the need for circulation and results in significantly less material usage and contingency requirement – contingency levels of 15 to 20% have been widely accepted by our Clients. Due to the high viscosity and the high inner cohesion of the mixed material, there is no risk of cement dispersion or dilution which results in faster offshore installation operations. NaX™ Q80 and NaX™ Q110 HPC grouts are designed and manufactured by Nautec and marketed under the NaX™ Premix System series.
Nautec works in close collaboration with prominent offshore contractors to deliver swift, reliable and cost effective grouting services for the installation of new offshore structures.
