Allspeeds has been awarded a contract to supply Webtool emergency disconnection tools for well intervention and workover in the Shah Deniz 2 field in the Caspian Sea. Webtool enables rapid cutting of umbilical multiple fluid transfer jumpers, electrical lines and tension wire, in the event of an emergency disconnect subsea.
Shah Deniz Stage 2 is located 70 kilometres south-east of Baku, at water depths of 50 to 550 metres, field development includes drilling 26 gas production wells and laying 500 km of subsea pipelines, which will connect ten subsea manifolds and the production wells.
The two Webtools are an integral part of an IWOCS-deployed, well commissioning tool. Within the tool, an umbilical is connected to sacrificial hoses and 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.
The Webtool offers a highly effective way of managing emergency disconnections using a sacrificial bundle that can be readily replaced if needed. It is also one of a few tools to cut tension wire together with cables and hoses and meet required Technology Readiness requirements for this important subsea application.
