    摘要: An off-shore floating oil production system is provided with an improved riser support.
    The oil production system comprises a floating vessel 2 having a moonpool 3 and a support system for supporting a riser 16 running through the moonpool 3. The support system comprises guides 7 in the moonpool 3, a carriage 6 which runs on the guides 7 and means 11 for supporting the carriage 6 which contains a pivoted support (12, 13) for the riser 16. Means 17 are also provided for permitting rotation between a section of the riser 16 and the carriage 6.
    Vertical movement of the carriage compensates for heaving of the vessel, movement of the pivoted support for pitching and rolling and movement of the rotatable means for «weathervaning».

    摘要: A hardenable epoxy resin composition comprising a curable epoxy resin, a hardener for the epoxy resin and a polyetherimide having the general formula;
    where

    X is CyH 2 y, or
    , or -S-
    y is a positive integer from 1 to 5
    m is 0 or 1
    n is a positive integer from 20 to 150 and
    R' is an aromatic hydrocarbon radical having from 6 to 20 carbon atoms, or a cycloalkylene radical having from 2 to 20 carbon atoms or a divalent radical of the formula
    where
    and
    x is a positive integer from 1 to 5. Preferably X is C 3 H 6 and R' is preferably


    The compositions are particularly suitable for use in fibre composite materials.
