    Abstract: An optical cable (31) includes: a stress wave detection optical cable (30) having an optical fiber (7) and a plurality of first steel wires (8) which are helically wound so as to surround the optical fiber (7) and which are surrounded by a flexible material (9); and second steel wires (32) different from the first steel wires (8). The stress wave detection optical cable (30) and the plurality of second steel wires (32) are helically wound to form one annular body as a whole, and a winding angle (α) of the stress wave detection optical cable (30) with respect to the axis is determined by a property value prescribed by Lamé constants of the flexible material (9).

    Abstract: Methods and systems for calculating a probability of failure and/or estimating a lifetime of an equipment component are disclosure. In an embodiment, a method of calculating a probability of failure of an equipment component comprises: generating a finite element model of the equipment component using device properties of the equipment component; using the finite element model of the equipment component to construct a polynomial basis for a polynomial chaos expansion; calculating expansion coefficients for the polynomial chaos expansion which express creep stress and strain in the equipment component as a function of operating parameters of the equipment component; receiving measured operating parameter values for the equipment component; and calculating a probability of failure of the equipment component using the measured operating parameter values.
