Drill Rig - Power plant upgrade
The power plant consists of four EMD engines, two 16 cylinder- and two 12 cylinder engines.
The four engines distribute their power through four generator circuit breakers onto the bus. No split options in place. From the main bus the power is transformed for its user-groups and also converter via for main power equipment.
Parts obsolescence, engine instabilities were the reason why Turner Engine Control Solutions received in 2012 the turn-key order to replace for each engine the existing generator control system at Scarabeo 6.
The generator control system consists of a Hill Graham AC40 master/slave module, automatic voltage regulator.
The spinning reserve power was calculated by an obsolete power limit module which had an interface signal through the SCR’s to reduce power. The functionality provided by the module has been replaced as well.
