1.3.3 Mooring lines/anchoring systems<br />
1.3.3.1 Mooring line components – materials<br />
Mooring chains<br />
One <strong>of</strong> the most common components used in all the different types <strong>of</strong> mooring lines are<br />
chains. In most cases the chain will be placed in the upper or/and lower part <strong>of</strong> the mooring<br />
line. There are two general types <strong>of</strong> chain; the stud link chain and the stud-less chain. A<br />
variety <strong>of</strong> chain dimensions, with different breaking loads, is available for all the types <strong>of</strong><br />
mooring lines. The main advantage <strong>of</strong> the stud link chain is that the stud geometry prevents<br />
the chain to entangle. However, the stud in the chain has a negative effect on the fatigue life<br />
<strong>of</strong> the mooring line. Therefore, stud-less chains are more commonly used in open sea<br />
mooring systems.<br />
