A method is described for using a particular spring element to facilitate the transfer of deck modules to a hull or jacket during the construction of an off-shore well platform. The spring element not only absorbs energy from the compressive loading expected during the transfer, but also resists any shear loading caused by relative motion between the module and the jacket or hull caused by the operation being performed in a body of water. The spring element includes two significantly different resistances to crushing when subjected to compressive loading including an initial resistance during which significant energy is absorbed. The spring element is also provided on the carrier barge between the barge and the deck module so that if the carrier barge should reengage the module once the transfer has been started, damage will be inhibited.

Off-shore platform construction, and method for transferring loads

A shock absorbing pad system for a missile launch tube, wherein the shock absorbing pad system comprises a continuously acting inner sheet, an outer segmented sheet and a plurality of chevron shaped struts disposed between the sheets. The continuously acting inner sheet provides compressive, shear, and tensile forces or a combination thereof to resist lateral shock loads and to restore the missile to its central location within the launch tube.
