    摘要: The coupling comprises a radially outer connection e.g. between tree surface 116 and conductor housing 114, adapted to make a rigid joint with a conductor casing 112. A radially inner connection, e.g. depending skirt 142 of the tree, is adapted to make a sealed joint directly with a casing hanger assembly 132, 136, 146, 150, 128 of the mudline suspension system 130. The invention thus substantially eliminates the use of additional hangers besides those of the mudline suspension system, simplifying the coupling assembly, and providing the possibility of reduced stackup heights. The relatively compact and simple coupling thus obtained gives shorter installation times and lower costs. The rigid joint between the coupling and the conductor casing 112 ensures that any external loading is transferred to the conductor casing 112.

    摘要: A method and apparatus for installing a metal annular seal (54) between the outer rough surface of a casing member (11) which has had a portion thereof cut away with a remaining portion projecting upwardly from the upper end of a casing head (12). A slip installation tool (18) mounted on the upper end of the casing head (12) carries a slip assembly which includes segmented slips (40), a bushing (22), and a cam member (42). The slip installation tool (18) secures the slips (40) about the outer rough surface of the casing (11) with bushing (22) acting as a supporting base or foundation to oppose the forces from the camming action because of support from lock down screws (24). After mounting of the slip assembly about the casing (11), the installation tool (18) is removed, and the metal seal (54) is mounted over the extending end of the casing (11) and deformed into metal-to-metal sealing relation between casing (11) and tubing head (50).

    摘要: A process for preparing an alkyl α-2-chloro-5- [4-(difluoromethyl)-4,5- dihydro-3-methyl-5- oxo-1H-1,2,4-triazol -1-yl]-2,4-substituted -benzene-propanoate herbicide, by reacting an alkyl α-acetyl-5- [4-(difluoromethyl)-4,5- dihydro-3-methyl-5- oxo-1H-1,2,4-triazol -1-yl]-2,4-disubstituted -benzene-propanoate, Intermediate D, first with sodium hypochlorite, then with a base, and recovering the herbicide. Intermediate D is prepared by reacting a 1-(2,4-disubstituted-5- halophenyl)-4-difluoromethyl-4, 5-dihydro-3-methyl-5- oxo-1H-1,2,4-triazole, Intermediate B, with an alkyl alkanoate in the presence of a palladium catalyst and a tertiary amine. Intermediate B is prepared by reacting a 1-(2,4-disubstituted- phenyl)-4-difluoromethyl-4, 5-dihydro-3-methyl-5- oxo-1H-1,2,4-triazole with a halogenating agent in the presence of an acid. The 2,4-substituents are independently selected from halo, alkyl, cycloalkyl, alkoxy, nitro, or hetercyclyl.

    摘要: A bucket conveyor apparatus (10) includes one or more conveyor chains, and a plurality of conveyor buckets which are pivotally mounted on the conveyor chains (24). While the buckets are positioned in spaced apart relationship along the chains (24), the present apparatus includes an arrangement for relatively reducing this relative spacing at an infeed station (12) of the apparatus. An arrangement of guide members (44) is provided for relatively reducing the effective length of the conveyor chains (24) thereby relatively reducing the spacing between the conveyor buckets at the infeed station (12). Efficient loading of material into the buckets is thus facilitated since spillage of material between the buckets during loading is substantially abated.

    摘要: A spread mooring arrangement is provided for use in deep water (greater than 200 meters) when it is advantageous to maximize the clearance between shuttle tankers (20) used for product off loading and the anchor legs associated with a spread mooring of the permanently moored tanker (10). Mooring insert tubes are provided at the bow and stern of the vessel. Bow mooring lines (30) extend from the sea floor through an opening of the bottom of the hull of the vessel and via a bow mooring insert tube (100) for securement on a chain pull-up deck (15). Stern mooring lines (40) extend from the sea floor through an opening in the bottom of the hull of the vessel and via a stern mooring insert tube (120) for securement on a chain pull-up deck (15). Space is available on one side of the vessel for a porch (65) for securement of production risers (70), work over risers and control umbilicals, thereby providing flexibility of the use of the vessel for the circumstance where production methods for the oil field change during its leftime or where other fields need to be coupled to the vessel with risers.
