Incident Narrative
"WHILE PERFORMING AN IN SERVICE 10 YEAR (IFR) INTERNAL FLOATING ROOF SEAL INSPECTION OF EQ111 GASOLINE TANK AT EAST COLEX THE INSPECTOR FOUND WHAT APPEARED TO BE A TEAR IN THE IFR STRUCTURE ALLOWING APPROXIMATELY 42 BBLS OF GASOLINE TO LEAVE PRIMARY CONTAINMENT LEFT SITTING IN 2 OF THE IFR PONTOONS. UPON INTERNAL INSPECTION OF THE TANK, TEARS WERE REVEALED AT FILLET WELDS WHERE TWO TANK LEG SLEEVES WERE WELDED TO THE INTERNAL FLOATING ROOF. THE TORN WELDS ARE BELIEVED TO BE THE RESULT OF THESE TWO ROOF LEGS BEING PINNED IN THE HIGH LEG POSITION, WHILE ALL OTHER ROOF LEGS WERE PINNED IN THE LOW LEG POSITION. THESE TWO LEGS BEING PINNED IN HIGH POSITION CAUSED THEM TO SLIDE ALONG THE TANK FLOOR AS THE ROOF WAS LANDED, CAUSING THEIR COLLARS TO BEND AND TEAR AT THE WELDS, CREATING TWO POINTS FOR GASOLINE TO ENTER THE PONTOON COMPARTMENTS. CURRENTLY TANK IS OUT OF SERVICE AND REPAIR WORK IS IN PROGRESS."
