To ensure the mooring legs are efficient in resisting the imposed

environmental horizontal forces, a target horizontal distance of 170 feet (52 meters) is

chosen between the predicted daylight location (where the chain exits the soil) and the

attachment point on the ship for each of the mooring legs. Therefore, anchor locations

are established at a horizontal distance of 270 feet (82 meters) away from the vessel.

at the various wind and current attack angles, as shown in Figure 4-2, with the origin of
