 joining links and shackles should never be welded in place due to the
probable resultant loss of tensile strength of the component.
Figure 4-1. Mooring Material Markings
4.2.5 BUOY COATINGS. Because protective coatings are frequently damaged by
impact or abrasion, it may be necessary to make in-service repairs to coatings of
mooring buoys. In order to repair these coatings, it is necessary to first clean the
exposed steel and the area surrounding the steel of rust, salt, and loose material.
This can be accomplished by wire brushing the steel (preferably power wire
brushing) or by scrubbing with a bristle brush and then drying the area with an
airhose connected to an oil free compressor (when required). The intact coating
surrounding the damaged areas should be abraded to ensure proper bond of the
repair material. There are several proprietary putty-like coatings available called
splash-zone compounds, that can be spread over the cleaned area, wet or dry. MI L-
P-28579(YD) describes such a curing epoxy-polyamide formulation. There are also
available a number of proprietary brush on coatings that can be applied to damp
surfaces and will cure either above or under water. Either type of coating should
completely cover the steel and extend at least one-half inch over the cleaned
coating surrounding the steel.
