cALMS PLC Support

All operators generally have maintenance/service contracts in place for the main automation system and larger rotating equipment. However, for the larger equipment packages, the focus is more on the mechanical equipment rather than the controls and the smaller packages generally have no maintenance contracts in place at all.

Subsea Tieback Project

A two-well subsea tieback to an existing Central North Sea Installation has recently been commissioned and started up in 4th Qtr 2020. The project had challenges due to the gas of the tieback being richer than the gas process on the host installation. This caused several control system challenges which had to be addressed. Core was involved in addressing some of the more complicated control challenges and was also involved in the start-up phase.

Control & Systems Upgrade

A key North Sea operator was looking to upgrade a problematic and obsolete control system on one of its platform generators. The generator was driven by a Rolls-Royce Avon 200 gas turbine and a EAS1-35 GEC power turbine. The Generator which has been in service since 1978 provides base load and supplies the power for the main gas lift and export compressor.

Safety System Upgrade

The original ESD system on the offshore installation was supplied by Wormald in 1993. An obsolescence status review had determined that spare parts for the system were no longer available and support of the system in its present form was no longer available from the OEM.
