Power generation apparatus

A marine power generation system for generating power from an ocean current, the system comprising:

• a generally elongate in-use platform having a length extending between two ends and a width extending between two lateral sides;
• the platform being configured to be positioned on the ocean floor;
• a plurality of spaced apart turbines positioned lengthwise along the length of the platform, each of said turbines comprising blades extending radially from a rotor, the turbine being operable to undergo rotational movement when positioned within an ocean current;
• one or more power generation modules, each power generation module being operably linked with one or more of the turbines, the power generation modules being located on or within the platform;
• an anchoring assembly for anchoring the platform to the ocean floor for aligning the plurality of turbines with the ocean current;
• wherein the rotor for each of said turbines is associated with a respective hydraulic pump that pumps hydraulic oil via hydraulic lines during rotation of the rotor and wherein the each power generation module comprises a hydraulic motor that is rotated with the hydraulic oil pumped by one or more of said hydraulic pumps associated with the turbines, the hydraulic generator being arranged to produce an electric output;
• and
• wherein the platform comprises an oil tanker vessel submerged to be positioned on the ocean floor with anchoring lines from the anchoring assembly being coupled to anchor locations located on one of two lateral side walls of the oil tanker extending along the length of the oil tanker.
