Abstract

1470943 Wells &c VETCO OFFSHORE INDUSTRIES INC 19 May 1975 [24 July 1974] 21331/75 Heading E1F A control system for operating a wellhead valve system at a subsea wellhead includes hydraulically actuated valve operators 14, 15, 16 connected through lines 28b, 29b, 30b, shuttle valves 28, 29, 30, and lines 28a, 29a, 30a respectively to an electro-hydraulic control pad 23 which receives electric signals from surface control 20 through supply line 22b, 23a and a pressure responsive sequencing valve 27 which is supplied with fluid from the surface through a single line 22a, 26 and whose output, under normal conditions, is supplied through line 27a to the control pad 23 but which can be switched, by changing the pressure in input line 22a, 26, to a selected one of the shuttle valves 28, 29, 30 through lines 27b, 27a, 27d respectively, to supply fluid directly to the valve operators 14, 15, 16 should the control pad 23 fail.
