These force coefficients are also a function of the angle of incidence of the current ฮฑ c, with respect to the tug heading, defined according to the Oil Companies International Marine Forum (OCIMF, 2008) convention, with 0 โ being at the tugboat's stern, increasing counterclockwise.. Note that, when calculating the final current forces on the tugboat, one must assume that the tugboat is.
