GCI announces completion of system
upgrade for Noble Drilling, USA
GCI has installed and commissioned a
Digital SCR and Generator Controls Upgrade for Noble
Drilling, USA. The upgrade was made on a legacy
International Switchboard Corporation (ISC) Type II control
system. The existing SCR controls were replaced with
an ABB DCR 500 rebuild kit designed to provide modern
controls and technology while utilizing the existing power
section components (SCR Bridge); the existing analog
Engine-Generator components were also replaced with a
digital Basler voltage regulator and Woodward digital
governor module providing a modern control and protection
scheme. Communication lines between the SCR room and
the Drill floor were upgraded to fiber optic cable providing
a high speed noise free channel.
A third Generator control bay and
custom 480VAC switchgear were also installed and
incorporated into the existing lineup. These additions will
provide the rig with additional power required to
accommodate modern drilling programs.
The
installation and upgrade was performed via shipyard
availability in Sabine Pass, TX.
