Abstract
An arrangement and a method for use in installation procedures for subsea transformers. A central, hole or tube is included in an encapsulation enclosing a transformer that is to be installed. Three core elements of the transformer are arranged symmetrically around the hole or tube forming a triangle or a delta. The transformer is lowered towards a a foundation placed on the sea floor wherein a guide pin is mounted. When the transformer has found its way to the foundation, the guide pin will enter the tube, and the transformer will slide down onto the guide line pin. The tube is terminated by a funnel shaped opening, thus making it easier not to miss the guide pin by the tube opening. The transformer is horizontally oriented by means of orientation keys localized within the tube.
