Abstract

1,268,064. Wells &c. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 29 July, 1969 [31 July, 1968], No. 37936/ 69. Heading E1F. Apparatus for carrying out operations on a subaqueous wellhead 17 comprises a drill string 27, a housing 28 engageable with a removable wellhead closure 19 and a support member 30 co-operating with a guide post 22 to set a latch 37 connected to a guideline 38. Guideline tensioning means 39 cause the latch to bear on a shoulder 36 of a sleeve 31 which is prevented from sliding relative to the member 30 by a detent. A sonar unit 41 and TV camera 42 are used to guide the member 30 down over to the guidepost and to set the latch on a coupling member 26. Further downward movement releases the detent and the member 30 slides downwardly relative to the sleeve so that co-operating means on the member 30 and guidepost orient the housing 28 for locking members 44 to engage the closure, when the drill string, is withdrawn the closure 19 is lifted away by the housing.
