  • Patent number: 5461904
    Abstract: It is an object of the present invention to provide a leak detection means that directs any leaked fluid to a single preselected radial point where it contacts and activates an indicating means. The means for defining the leakage flow path to the indicating means also acts as a barrier preventing contamination of the flange bolts by any leaking fluid.

  • Patent number: 4793418
    Abstract: An offshore marine structure and method, which structure includes a leg supported deck which holds hydrocarbon fluid processing equipment above the water's surface, and includes vertically aligned conductor guides. A self supporting fluid separator is positioned in said marine structure to receive a multi-phase stream of a hydrocarbon fluid from one or more wells. An upper segment of the fluid separator is slidably registered in vertically aligned conductor guides. A lower segment of the separator is embedded in the sea floor and operably engaged with said upper segment. A conductor riser is adjacently positioned by conductor guides in the marine structure to receive hydrocarbon liquid from the fluid separator. Discrete liquid, and combined vaporous flows are then conducted to the processing equipment for further handling.

  • Patent number: 4721163
    Abstract: A tubing hanger alignment system for a subsea well, periodically subjected to treatment by removing the well tubing and inserting treating tools therein, wherein a tubing guidance system cooperating with the wellhead for engaging a downwardly moving tubing hanger running system thereby to rotate said tubing hanger sufficiently to position the carried tubing at a predetermined relationship with the wellhead, thereby providing access into the tubing hanger for sealing elements of an over-positioned subsea tree co-operative with the wellhead.

  • Patent number: 4705114
    Abstract: A subsea system for transmitting a multiphase flow of hydrocarbons produced from a subsea well positioned remotely from fluid storing and treating facilities. The system includes a subsea well template which encloses a plurality of well heads. A composite hydrocarbon flow is manifolded from the respective wells and conducted to a fluid separator which causes the composite stream to separate into discrete liquid and vaporous flows. The latter are then conducted through a multi-conductor riser to the treating and storage facility.

  • Patent number: 4644983
    Abstract: Apparatus for reducing spillage in connection with a liquid product loading dock. It has a double funnel arrangement with one funnel attached to the first swivel of plural fill pipes which have swivel joints to permit placing the free end into a mobile tank to be filled. That funnel moves with the fill pipes through about one hundred eighty degrees of freedom, and has structure for receiving the free end of the fill pipes after a filling operation. Consequently, run off of product from the fill pipes goes into the funnel. There is a conduit connected to the funnel outlet that moves with it and extends into a second funnel that is coaxial with the product delivery pipe. From there, the run off is returned to a collection tank.

  • Patent number: 4563032
    Abstract: A pulling head adapted to removably engage the end fitting of a conduit to facilitate the latter being pulled with a substantial tensional force. The head includes an engaging ring at one end thereof which is removably operable to register about and firmly engage the cable end fitting. A wire line extending from the pulling head nose end is attachable to a winch or other mechanism capable of applying the necessary pulling force thereto.

  • Patent number: 4519727
    Abstract: A well head protector for a well which is located at the floor of an offshore body of water. The protector includes a plurality of discrete sub-assemblies which, for installation purposes, are initially transported to a drilling vessel and positioned above the well head. The sub-assemblies are sequentially lowered from the vessel deck and assembled above the water surface into a composite unit. The completed unit is guidably lowered by the vessel's drilling derrick to its position surrounding the well head. The deflecting elements are then lowered into place.

  • Patent number: 4519726
    Abstract: Riser for an offshore marine platform which includes facilities to receive, treat, and/or store hydrocarbon fluid from a plurality of dispersed submerged wells. The riser includes means to accommodate a plurality of conduits between the platform deck and the floor of the body of water. As a rigid, or non-rigid conduit is pulled downwardly through the riser, it engages a deflecting shoe. The latter deflects the pulled conduit into a direction away from the platform and along the ocean floor, whereby it can readily engage a pipeline, or attach to one of the dispersed wells.

  • Patent number: 4287098
    Abstract: A large scale method is provided for the production of exhaust and industrial gas filters comprising aluminium oxide produced by the decomposition of alumina hydrate deposited on a substrate.A plurality of substrates are mounted on a stand, immersed in an alkali metal aluminate solution while the stand is subjected to motion through the solution, thereby causing the solution to flow over and through the substrates while alumina hydrate is deposited on them.
