Question 3 [7 marks] In the reliability analysis of offshore wind turbine support structures, one of the Limit State Functions (LSF) is based on the plastic yielding criteria. This LSF can be defined at the relevant points on a specific structure as: gD - D - 2TS - M where D is the tower base and platform diameter, T is the thickness at tower base level, S is a stress parameter, and M is the bending moment at tower base. Assume that S, M, and T are independent normal random variables with the following parameters: Basic Mean Coefficient of variable variation S 235 MN/m^2 0.04 M 160 MN.m 0.07 T 0.027 m 0.03 Assume that D is a deterministic parameter equal to 6 m. Determine the reliability index and probability of failure corresponding to this LSF. All the variables are given in compatible units.

Question 6: List the steps involved in computing the Internal Rate of Return (IRR) and Modified Internal Rate of Return (MIRR) of an investment. XYZ Ltd is considering an investment proposal for a new item of equipment for its plant. The equipment would cost \$360 000 (including installation). It is estimated that the equipment would generate positive cash flows of \$120,000 in year 1, 80,000 in year2, 75,000 in year 3, 90,000 in year 4 and 100,000 in year 5, and would have a five-year useful life. The required rate of return is 10%. a. What is the IRR of this investment? b. What is the MIRR of this investment? On the basis of IRR and MIRR analysis, should the project be accepted? Give reasons for your decision. Use the Discount Rate of 8%.
