Load Testing of Padeyes
Load-testing of Padeyes
Padeyes are welded above equipment where a vertical lift only is required, usually located above heavy valves or compact pump units.
Padeyes welded on the deck are used to secure loose equipment such as inflatable liferafts or rope ladders and to secure tie wires.
They are both static load tested using the proof loads being witnessed by the Certifying Authotity (see sketches in image section)
Load-testing Padeyes Above Equipment
The padeye i/d is stamped onto the padeye using soft nose stamps. (I used to request the padeyes stamped both faces when being fabricated at the plate shop.) They are welded to the support structure above the equipment and this welding is subjected to pre-test NDT.
The proof is suspended from the padeye for a few minutes then removed. The attachment is then subjected to post test NDT. Following successful NDT report, the padeye can be painted yellow, with the I/D and SWL stencilled alongside, a Padeye Load-test Certificate can be issued.
Load-testing Padeyes Welded to Deck
These are fabricated and hard stamped with I/D No, and welded to the deck, and post test NDT carried out on the attachment welds.
Most of these padeyes can be load tested using an overhead crane, with a load-cell between the crane hook and the padeye. Some are inaccessible by crane so a small hydraulic jack can be used to simulate a static load condition, and support welding subjected to post test NDT. As before once NDT clear report has been issued the padeyes are painted yellow and a padeye Load-test Certificate issued.
All padeye load test certification packages will be sent offshore at sailaway.
