We are estimated to begin stack testing on the BlackHawk on June 3.

Hope everyone has a good weekend!

Hey Eva,

It will not be a compliance test on the BlackHawk. This stack test will only be to gather data on the

engines.

Thanks,

Sara

Sara,

David McNeal has revi ewed the Emission Test Protocol for the Diamond BlaclHawk drillship and does

not see any problems with the test methods that you are proposing to use.

However, we would like to know why only two of the eight engines will be tested. Based upon test data

w e have seen in the past, emissions from “identical” engines can vary quite a bit. From what we have

seen during previous engine testing on drill rigs, we would be concerned if the upcoming test results will

be used for determining compliance if only two en gines are tested. Yet, if the testing is not being used

for compliance than it will be fine, but we would like to know the reason for only testing two of the eight

engine.

Thank you for your submittal.

Eva Land
