The current speed influences the safety of subsea and marine operations. This paper proposes an algorithm to estimate the depth-dependent current profile though data from existing commercial sensors, that is the mooring line tension measurements and riser end angle measurements. This will aid prediction of the weather window to enhance the safety during the subsea operations. The influence of various current profile types and the vessel’s motion are discussed. A governing equation is proposed for the algorithm. A simulation is conducted to verify the algorithm.
