    Abstract: A power supply assembly, which is placed subsea and is connected to an umbilical from a platform, supplies electrical power to subsea equipment. The power supply assembly supplies power during drilling operations to a pump for pumping drilling fluid from the sea floor to the sea surface. During production operations, the power supply assembly provides power to a booster pump to pump the well fluid away from the subsea well for collection. The subsea power supply assembly optionally also provides power to electrically charged portions of subsea separators that remove water from the oil in the well fluid. The booster pump the pumps the oil from the separator away from the subsea wellhead for collection.

    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.

    Abstract: System and method for coupling of a bottom based pipeline to an adjacent riser pipe or another pipeline, of the kind wherein is utilized a bottom based coupling frame. The underside of the frame (2) is designed in order to undergo displaceable movements along the sea bottom or on a fundament thereon both during and subsequent to coupling of the pipelines to the frame. On the frame are mounted coupling members for one importing and one exporting pipeline, and a pipe connection between the pipe couplings, optionally including a valve and other equipment. In accordance with the method, a tool including a winch and a pulling wire, is mounted on the frame whereby the frame, including the pipeline, can be pulled together in order to accomplish the coupling operations.
