A turret mooring system for a tidal turbine assembly uses a bifurcated mooring line 116, 118 attached at spaced attachment points 128 to increase the torque exerted by the turret 100 so that it will not be over-rotated by frictional forces between the turret 100 and the assembly 150 moored to the turret 100. The bifurcation 120 may be located within 10% of the length of the line from the chain table attachment points 128. The main length of the mooring line 116 may use chain, while the bifurcated portion 118 may use a pair of low mass synthetic cables, connected via a bridle 120. Alternatively, frictional forces may be reduced by the turret providing an upward force to the assembly, which may also resist pitching moments.
