2.6 MANUAL ESD PUSH-BUTTONS
Manual ESD push-buttons have been located on the WHCP and on the ICSS Panel of the Platform (on a dedicated manual shut-down panel).
ESD push-buttons on WHCP are of a key reset type or pull ring with pin, specifically manufactured for this purpose. Once operated, the station shall remain in alarm position until manual reset.
The resultant actions of Manual ESD push-buttons will be:
• close the Sub-Surface Safety Valves of the Wells (SSSV);
• automatic ESD.
