Fire tested for
steel equivalency........ As part of a DNV approval
process for one of our decks, we conducted a full blown fire test on a
sample helideck to established the equivalency between an aluminum and
steel deck. A 5m x 5m helideck comprised of the Heliflex 6000CL decking
planks supported by the Heliflex I12 aluminum girders, was fire tested
at our facilities in South Carolina under the guidance of a DNV
surveyor. The test procedure was defined and requirements set by DNV
Oslo. A 12,000# concrete block supported by a four legged support
frame was fitted above the deck at a location required by DNV. The
concrete weight simulated the weight of a typical helideck. The deck was
filled with 400 gallons of Kerosene and was lighted. The test consisted
of monitoring any damage, structural failure or any other signs of
distress to the helideck after a 10 minute burn test. No damage was
observed after the test and DNV certified the equivalency of aluminum
deck to a steel one.
Friction Coefficient, Safety net Drop
Test, Tie-downs Pull test - DNV certified....
Tests to confirm
compliance with CAP 437 requirements for the deck friction, safety net
drop test and tie-downs pull test have been performed at our facilities
in South Carolina and have been witnessed and certified by third party
inspectors and DNV.
- Friction coefficient:
The test revealed a coefficient of friction above 1.0 in both
directions of the deck top surface.
- Safety net Test: An
actual safety net panel supported by two aluminum outriggers was
tested as per CAP 437 test requirements and the safety net
components sustained the test loads without any damage or failure.
- Tie-downs Pull test:
Our standard D-ring tie down assembly was test in the presence of a
DNV surveyor who confirmed the pull value of 6000#. The test was
stopped at the 6000# mark without any signs of failure of the D-ring
or its attachment to the deck.
