Ship Design > Consultancy Offshore Engineering ONLINE RESOURCE CONTACT MOORING LINE CATENARY CALCULATION. Apr 26, 2020 · Fig. 5 segments with different properties can be defined along with a Buoy at each segment end (except the last segment) which basically adds an additional upward force at that end. This, in turn determines the length of the mooring line required and also the shape of the suspended catenary. Fig. Through gravity the catenaries, between the floating unit and the seabed, will show the typical shape of a free hanging line. The catenaries are hanging horizontally at the seabed. Appreciating that AtoN buoy mooring lines are often dimensioned with a rule of thumb and regularly end up as being too short for most site conditions, IALA has developed an easy to use numerical catenary mooring line calculator, derived from their own mooring calculators. 1.
