{"title":"1965","authors":"C.

The mechanism is mechanically latched, unlatched, and packed off with a device which is operable internally of the well tool by rotating a translatory member. This invention relates to an apparatus for use at off shore wells and pertains more particularly to latch means for securing a well tool, such as a blowout preventer, a riser pipe or a production mandrel, to a wellhead. In the search to find new oil fields, an increasing amount of drilling has been conducted at offshore locations. As the depths have increased, it has become necessary to drill these wells from floating barges and locate the cas ing head and the wellhead equipment underwater to ob viate the need for erecting a platform for placement of : the wellhead equipment. In order to install equipment of this type underwater in depths greater than the shallow depth at which a diver can operate, it has become neces sary to look to remotely installed equipment. Concur rently on the market are designs of underwater latches that are hydraulically actuated through flexible hoses that may become broken. These broken hoses may be repaired by a diver in relatively shallow water; but at the greater depths this becomes increasingly difficult, if not impos sible. It is therefore one object of this invention to provide a new and improved latch means for securing well tools to a wellhead. Another object of the invention is to provide mechani cal latch means for (releasably) securing well tools to a wellhead. Still another object is to provide a mechanical latch means which is controllable from a location remote there from for securing a well tool to a wellhead. A still further object of this invention is to provide a mechanical latch means, which is remotely controlled, for releasably securing a well tool to a wellhead. Another object of this invention is ot provide a me chanically actuated latch means for latching a well tool to an underwater wellhead whereby substantially all axial movement and lateral movement of said well tool may be prevented. Still another object of this invention is to provide a mechanically actuated latch means having a mechanically actuated compression seal. It is also an object of this invention to provide a tool for latching a tubular body into an open ended tubular member which tool can be mechanically internally released. Additional objects and advantages of the invention will become apparent from the following description on an embodiment of the present invention when taken in con junction with the appended claims and the accompany ing drawings, wherein: FIG. 1 is an elevational view, partially in section, of the latch means in the position just after inserting the well tool to be latched into an underwater wellhead; FIG. 2 is an elevational view, partially in section, show O","PeriodicalId":172815,"journal":{"name":"Lie on your wounds","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116991446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
