5.
Map and complete description of all chafe, bearing or nip points and any chafing gear used. Include
Polaroid photos when practical.
6. Description of use of carpenter stopper, chain stopper or other hardware on rope. Where
(lengthwise) was stopper placed on rope?
7. For fiber line hawsers, how it was secured on towing vessel' e.g, wrapped around mia traction
n
sheave/drum, stopped on the H-bitts, etc.
8. Give minimum depth of water traversed. Did hawser drag bottom9 Give details.
9. If hawser was passed to a wreck, was it:
a.
Floated
b.
Dragged across bottom
(1)
Distance dragged
(2)
Type of bottom.
10. Other experiences of note (surging against hawser/components, fouling on rocks or ship's
appendages, etc.).
11. Between-tow maintenance; give information on type of lubricant used, how used and by whom
applied.
PART C: POST-OPERATIONS ENTRY
Record after every use:
1.
Specific inspection of hawser for wear points such as carpenter or chain stopper wear points,
caprail/nipping chafe area, shock bearing points, sheaves and fairleads, etc. Include photographs.
2. Quantification of wear:
a. General and wire rope. Include count of fish hooks and record and identify (map) spots. Count
fish hooks per strand lay. Count all broken wires, not just those that protrude from the rope.
Record maximum number of broken wires per lay (total) and maximum number of broken wires
per strand lay Include information on any birdcaging, kinking, broken surface wires and surface
wire flattening.
Indicate surface corrosion. Include photographs.
Periodic inspection/
maintenance of hawser or components, which includes opening the lays and internal inspection,
need not be performed after every employment, but when undertaken, it should be logged When
lubrication is performed, carefully log stock number and manufacturer's data on lubricant as well
as who performed the maintenance and inspection.
b. Fiber line. Include information on surface chafing and abrasion wear, kinking or any other visible
damage. Include photographs.
c. Chain. Pay particular attention to the link bearing points (the "grip" area). Pay special attention
to places along the chain where it passed through or bore against chocks or fairleads. In these
latter places a straight edge should be laid against the flat face of the link to ensure that the link
is not bent in this plane. Any bending is to be reported as failure and requires replacement.
d. Joining links and shackles of all kinds. Inspect the mechanical joints and screw threads. In the
case of safety shackles, measure the mortice to ensure that the bow is not sprung. If sprung,
dispose of the shackle. Ensure that all detachable link pieces have serial numbers and are
matched in sets. Ensure also that the hairpins fit snugly.

General comments . Include as a minimum a general post-operations observation of hawser,
component and end-fitting.
