7、es as follows:3.1.1 Type IMultiple-line (doubling up), self-adjustable, accommodating the mooring line combinations listed in Table 1.3.1.2 Type IISingle-line, self-adjustable, accommodating a single 5-mm wire to a 76-mm-diameter mooring line.3.1.3 Type IIIConical shape with tapered, slotted sleeve.

8、 Type III rat guards shall be of the following sizes: (a) 75 mm, (b)125 mm, and (c) 200 mm.3.2 Types I and II rat guards (see 3.1.1 and 3.1.2) are designed to be installed from the deck or pier without a person physicallycoming in contact with the mooring lines or hawser, by lowering and positioning

9、 the guards away from the shipsships hull withtwo ropes that are permanently attached as guide and tie ropes (see Fig. 1).3.3 Type III rat guards (see 3.1.3) require a person to contact the mooring line to pull the two halves of the conical guard aroundthe mooring line, wrap the slotted sleeves (see

10、 Fig. 2) to the line, and physically close any opening between the mooring line andthe circular opening at the center of the guard.4.
