Tank Jacking Procedure Oil Storage Tank Installation Guide

Jacking Method.Jacking method is a kind of storage tank installation method that refers to the bottom of storage tank as the reference plane,the wall in the top of the storage tank and the tank roof will be installed firstly,then assemble and weld the storage tank wall from top to the bottom of the storage tank until the installation of tank bottom is completed.Tank Water Reservoir Anchor CAI Safety SystemsOur tank fall protection anchor is designed to be installed without penetrating the tank surface through drilling or welding.The OSHA compliant anchor clamps against tank and water reservoir vent and can be set to provide fall arrest or fall restraint safety.The basic system comprises of one each anchor,trolley,cable grab with lifeline,and shock absorbing lanyard.THIS PAGE INTENTIONALLY LEFT BLANKOct 11,2016 self anchored tanks bottom plate#0183;bottom of Tank 5 is an estimated 100-feet above the groundwater lens.The Navy operates a Maui-type water well under Red Hill about 1000-feet makai (towards Pearl Harbor) of Tank 5.The Honolulu Board of Water Supply operates wells on either side of Red Hill in the area of Moanalua and Halawa Valleys.
