Wave Powered Generator Reliability Analysis:
A developer of an innovative renewable energy device required some guidance on prototype testing. The near-shore wave energy
device used untested technology and presented some maintenance
challenges due to its proposed location in heavy seas.
We provided a reliability study for the testing of the
prototype using an ARMS approach, which examines the complex
relationship between Availability, Reliability, Maintainability and Safety.
Using generic component reliability data and experience of marine
maintenance and technology development, we provided valuable advice on the
expected reliability, on which components would be likely to require attention during the
test programme, on a spares strategy and on maintenance procedures.
This information allowed the client to provide their investors with a
detailed picture of the investment risk associated with the testing and
further development of this device.
Nuclear Power Station Aircraft Impact Assessment:
An aircraft impact on a nuclear power station could lead to a catastrophic
radiological release. It is therefore necessary to demonstrate, for each
station, that the risk associated with such an event is acceptable.
The client had evaluated the consequences of an accidental impact by various categories of aircraft on various parts of the power station. In order to
calculate the risk, they needed to know the likelihood of each of these
events. We used international aviation accident data, along with details of
local military, commercial and private aviation activity to calculate the
frequency of an impact on various parts of the station.
This allowed the client to demonstrate to the regulator, using independently
generated data, that the risk associated with this hazard was acceptable.
