  "textContent": "A power transmission and distribution system is described that it is suitable for subsea electrical loads. The system includes a primary dc transmission cable (8) that can be connected to an onshore AC/DC converter module (2) that connects the onshore end of the cable to an ac supply network (4). The subsea end of the cable (8) is connected to a primary subsea power distribution unit (10) which functions as a central power unit. The primary subsea power distribution unit (10) includes a DC/DC converter module (14) having a modular topology with a series of interconnected DC/DC converter units. The DC/DC converter module (14) is connected between the cable (8) and a primary dc distribution network (16). Secondary dc transmission cables (24) and associated circuit breakers (26) connect the primary subsea power distribution unit (10) to secondary subsea power distribution units (18a,18b) that are located near to the subsea electrical loads. Each secondary subsea power distribution unit (18a,18b) includes a DC/DC converter module (20a,20b) having a modular topology with a series of interconnected DC/DC converter units. Respective secondary dc distribution networks (22a,22b) are used to supply power to one or more subsea electrical loads, optionally be means of power converters (30,36,38,44).",
