Master of System Support Engineering - HMAS Westralia Fire - Assignment Help

Assignment Task:

Task:

Problem 1: Show that the mean time to failure of a parallel system of n identical components, each with an exponential time to failure with mean 1/λ, is(8 points)
Problem 2). A pump/filter system supplies clean fluid to a production process. The system consists of two subsystems in parallel (S1 and S2), to increase reliability. Each subsystem consists of one pump and a filtering element in series. S1 has one filter as the filtering element. The filtering element of S2 has two filters in parallel. Failure rate of each pump is 1.5 per year (failure time exponentially distributed), and of each filter, 2.5 per year (exponentially distributed), when they operate.

a). Draw the reliability block diagram of the pump/filter system.
b). Calculate the reliability of the system for 9 months of operation.
c) Find Mean Time To Failure (MTTF) of the system.

Problem 3).
a). What are the operational risks in a supply chain network? How do they differ from disruption risks? Explain with appropriate examples.

b). How well are supply chain risks recognised across a network? What can Companies do to enhance supply chain risk management capabilities?

c). A large medical device manufacturer has experienced a number of disruptions to operations and customer service within their supply chain. As a result of this, the supply management team at the company is tasked with creating a framework to better understand the drivers that create supply disruptions and mitigate the risk. How will the team develop a framework for reducing the impact of disruptions to the supply chain?

d). How can the implementation of Supply Chain Risk Management processes be organised within and across companies?

Summary

On 5 May 98, WESTRALIA sailed from Fleet Base West for the Western Australia Exercise Area to rendezvous with HMA Ships SUCCESS, DARWIN and ADELAIDE. A fire in the main machinery space of WESTRALIA resulted in the loss of the lives of four crew and injuries to several other crew members. Prior to the ship sailing from Fleet Base West on 5 May 98, WESTRALIA had undergone an assisted maintenance period for about 6 weeks. During this period, members of the ship’s company of WESTRALIA in conjunction with Fleet Intermediate Maintenance Authority and the ship’s contractor, ADI Limited, carried out maintenance work. The work included the fitting of new flexible fuel hoses to the ship’s main engines by a subcontractor under the direction of ADI Limited.

After departing at 0900 on 5 May 98, at about 1030, when about 21⁄2 miles east of the Fairway Buoy in the Deepwater Channel, a fuel leak was noticed in the area of the number 9 cylinder on the inboard side of the port main engine. It was a significant leak, with fuel emerging under pressure in a manner similar to a garden hose.
