Operational Review/Report

The objective of this task is to publish a report on operational performance and use the report to support exploitation.

Key results:

Video showing the CREEV Expander unit is bested to capture the performance data

At 5500rpm, SFC improved by 21% from previous Gen1 expander

288.83g/kWhr to 238.7 g/kWhr.

SFC Vs rpm; Gen1 & Gen2 Expander Comparison
SFC Vs rpm; Gen1 & Gen2 Expander Comparison

At 5500rpm, power improvement by 14% from previous Gen1 expander

18.32kW to 21.39kW.

Further work is required to develop the oil strategy to improve hydrocarbon emission for Euro6. 65db noise level is achievable, again further development required in post project activities.
