Fittings should not exhibit outward signs of distress or failure prior to
conducting a load test.
Test Preparation - General
Testing personnel should provide test jigs, jacks, pumps, wire rope
rigging, chain falls and dynamometer, as required to perform the test
Precautionary measures should be taken to prevent damage to the fitting,
dock structure, or fender system. Wood blocks, sheet copper, etc. should be provided
to prevent chafing and rope burns as necessary.
Monitoring points should be established on the fitting or fastener to track
movement under load. Movement should be recorded in the three principal axes. A
reference point independent of the fitting or fastener and its foundation should be
established to find movement. Surveying methods can be employed to track movement
from a safe distance. A target could be affixed to the fitting and readings taken (x, y, z)
during the test.
The strip of concrete surrounding the base plate of each fitting and the
surface of the free edge of the concrete in front of the fitting must be visually inspected
for shear cracks. To aid detection of potential shear cracks, it is recommended that and
approximately 0.3 meters (1 foot) wide strip surrounding the base plate and the surface
of the free edge of the concrete in front of the fitting, be painted with white wash or light
colored brittle paint.
\ Accomplish all work operations in accordance with the standards
identified in Appendix A. Provide U.S. Coast Guard (USCG) approved life jackets or
buoyant work vests to employees working over or near water, where the danger of
falling into the water and/or drowning exists. Encourage employees to utilize such
equipment. Evaluate the requirement for the use of personal floatation devices (PFDs)
on piers, taking into consideration falling/tripping hazards, proximity to edge,
obstacles/obstructions, availability and placement of life rings with lines, access ladders,
Provisions should be made for keeping personnel not involved in the test
clear of the test site and any danger areas.
Using the test jig, chain falls, dynamometer, etc. and a wire rope pendant,
exert a horizontal pull equivalent to 110% of the rated working load for the test fitting or
fastener. Application of the load should be 100 mm (4 inches) below the lip, horn, or
other line holding device on fittings. The load should be held for 10 minutes. At the end
of 10 minutes, the fitting or fastener should be examined for any evidence of failure.
The results should be recorded on the load test record sheet.
SECTION 6 REPORTING
All results of testing should be recorded on the deck fitting load test record shown in
Figure B-1. These records should be included in the baseline report prepared under
Section 5 of this document.
