After the Caribbean Princess and the Crown Princess had already been equipped in the past with the new IREG excitation system, LST has now received another order from the shipping company Princess Cruises to modernize the excitation systems on the Island Princess.
It contains the delivery of 3 digital IREG excitation systems, as a replacement for the existing Alstom voltage regulator for supplying the 3 x 18 MVA generators on board.
