NOVELTY - The method involves turning turbine blades of turbine provided at a region of a subsea pipe (203) or umbilical (260) through respective motion of seawater (280) through a swept area associated with the turbine blades. The electrical power is generated responsive to turning of the turbine blades. The power is generated locally through the turbine on the pipe. The power is provided to auxiliary equipment on or proximate to the region of the pipe. The respective motion of seawater is provided by continuously moving the blades through a surface of seawater.    USE - Method for generating electrical power.    ADVANTAGE - The electrical power is generated locally near a region of a subsea pipe or umbilical or other such structure. The electrical power is generated endlessly through respective motion of sea water through a swept area of turbine blades of a turbine which can be located or is located subsea on a pipe or umbilical or other such structure. The dynamic control is obtained over the movement of a riser pipe in a water column with an ability to generate power from the current and/or tidal action experienced in the area. The electricity is generated locally in sufficient amounts to power monitoring and communication systems and other such auxiliary equipment to enable systems remote from more permanent power reserves to operate independently of umbilical-like connections. The surplus energy is enabled to be stored in batteries or capacitance devices or transmitted through umbilical to a platform to supplement existing power supplies and/or provide green power. The electrical power is obtained as endless source for the auxiliary equipment without the need for complex electrical connection systems or for batteries to be replaced or recharged.
