Guidelines for Handling, Inspection

and Removal from Service of

Wire Mooring Lines

8.1 HANDLING

• Prevent kink.ing of lines. When unreeling, the reel should be mounted on a spindle and the
  line pulled direct Iy off tbe reel, not over the end. If a loop forms, it should be thrown out
  immediately, before any load is placed OD the line.


• The coiling of the first layer of a line on a plain winch drum, depending on the lay of t.he
  line, should be in the direction shown in Figure 81.


• Wire lines should be lubricated periodically. Proper lubricarion reduces the abrasive effect
  of individual wires sliding against one another and helps to prevent corrosion. Wire Hnes are
  lubricated during manufacture, but litis initial lrealmenl is lost during use, particularly in
  marine applications. Ideally, the tine should be lubricated every two or three months. Several
  patent variet.ies of wire line oil are available and the lubricant may be brushed on or a box
  lubricator used. Mooring line manufacturer's recommendations should be followed.

This rute will help 10 determine the correct lay (left or righl) of rope to use on a given drum. The right

hand represents right lay rope and the lelt hand represents left lay rope. The Index finger and thumb

are extended with the olher fingers being closed inlO a list. The fisl represenls the drum. Ihe index

finger is .he rope coming onlo the drum, and the lhumb points 10 lhe side al which lhe rope is la be

fastened. For ollerwind the palrl) IS down and for underwind lhe palm IS up.
