Sitra Sub-Sea Cable Water Quality Monitoring

Sitra Sub-Sea Cable Water Quality Monitoring

Prysmian Group were appointed as the contractor to undertake the installation of a 400kV High Voltage power line between the Al-Hidd Grid 400 kV Substation and the Riffa Grid 400 kV Substation. A total of 4.25km of this cable installation involved laying a sub-sea cable.

The Supreme Council for Environment (SCE) requires that levels of Total Suspended Solids (measured as TSS in mg/l) should be monitored to ensure that any deterioration in water quality can be readily detected so that immediate action can be taken.

Sitra Sub-Sea Cable Water Quality Monitoring

Our Role

As part of the offshore cable laying and burial works, Ayesa developed a Total Suspended Solids (TSS) Monitoring Protocol which outlined the water quality monitoring programme in compliance with the SCE’s guidelines on TSS monitoring (EIA-9). The protocol also recommended additional mitigation measures and provided best practice measures for the land-based cable works, where applicable.

Ayesa supervised the TSS monitoring and conducted fortnightly environmental health and safety inspections of the land-based activities.

The findings of the TSS monitoring and site inspections were presented in monthly reports to the client and the SCE.
