Pierce, R H

A marine riser is described for use in drilling or production of hydrocarbons from a subsea formation comprising: elongated tubular body means constructed of a composite of elongated filaments of a material in a resin matrix having a modulus of elasticity not less than about 27x10/sup 6/ psi. The filaments is bonded in a resin matrix to form a load bearing member of the tubular body means having an elastic elongation strain characteristic under stress in tension not substantially greater than steel; and coupling means at opposite ends of the tubular body means for coupling the riser to a member for transmission of tensile loads through the tubular body means between the ends.
