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 Pascagoula, MS.
