Purpose of the mooring system is to maintain the floating drilling vessel within certain horizontal limits of the well's center line (usually not exceeding 5 to 6% of water depth) so that drilling operations can be successfully carried out. In general there are two types of mooring patterns which can be used with any particular type of vessel: omni-environmental loads from any attack angle (0 to 360 deg); and uni-directional pattern in which there is a strong, prevailing environmental direction. Paper analyses types of anchors, anchor-, cables and chains and presents in graphical form: wind, wave, drift and current loads: mooring forces vs displacement: chain deployment geometry; and hp requirements to deploy an anchor chain.
