Then profiles of 80, 40, 20, 10, and 5 per- cent of the current speeds were used to investigate how the mooring behaved under lower current speed profiles. The drag on each section was calculated with the line section normal to the flow, using the equation: F. - C In this equation: £ is the density of seawater (approximately 3 2 slugs/ft ), A. is the projected area of the line section, its diameter times its length, U is the speed of the current, and C is the drag coefficient ( for all line) U, where not constant with depth, was calculated in two ways. In the first program a simple average of the U value at the top and the bottom of each individual line section was taken. This average value was used in the drag equation. 74.
