8、.1.1 and 3.1.2) aredesigned to be installed from the deck or pier without a personphysically coming in contact with the mooring lines or hawser,by lowering and positioning the guards away from the shipshull with two ropes that are permanently attached as guide andtie ropes (see Fig. 1).3.3 Type III

9、rat guards (see 3.1.3) require a person to contactthe mooring line to pull the two halves of the conical guardaround the mooring line, wrap the slotted sleeves (see Fig. 2)to the line, and physically close any opening between themooring line and the circular opening at the center of theguard.4.
