Disconnect tools for Shah Deniz intervention system

Offshore staff

ACCRINGTON, UKAllspeeds will supply two Webtool emergency disconnection tools for well intervention and workover operations at the Shah Deniz 2 field development in the Azeri sector of the Caspian Sea.

Shah Deniz 2, 70 km (43 mi) southeast of Baku in water depths of 50-550 m (164-1,804 ft), involves drilling 26 gas production wells and laying 500 km (310 mi) of subsea pipelines, connected to 10 subsea manifolds and the production wells.

Webtools are designed for fast cutting of umbilical multiple fluid transfer jumpers, electrical lines and tension wire in the event of an emergency disconnect subsea.

The two deployed for Shah Deniz 2 will form part of an IWOCS-deployed, well commissioning tool.

Within this, an umbilical is connected to sacrificial hoses and a cable bundle securely positioned in the mouth of the Webtool emergency cutter. Once activated the sacrificial bundle is cut in a single operation within seconds.
