TTI-FSS Delivers World’s Largest Sulfur Melter Tank

Shipping completed tank instead of field erection created substantial savings for client, reduced safety risks and decreased project completion time.

The world's largest sulfur melter tank measures 21' 6" in outside diameter, is 29' 6" tall and weighs approximately 85,000 pounds.

In mid-May, Tampa Tank Inc.-Florida Structural Steel (TTI-FSS) delivered the world’s largest sulfur melter tank from its fabrication facility in Lakeland, Florida, to a plant in central Florida. The tank, with an outside diameter of 21 feet and six inches, is 29 feet and six inches tall and weighs approximately 85,000 pounds.

The 20-mile delivery trek, which took 12 hours over two nights, required teamwork among 12 different companies and 30 people with 21 vehicles. TTI-FSS designed and built a cradle and trailer specifically for the transition. The fontain trailer was fabricated with outrigging ballast supports, which were stacked with 15,000 pounds of ballast plate to drop the tank’s center of gravity for stabilization during the trip.

On Friday, May15, after a 9:00 p.m. safety meeting, the tank was released to begin its voyage, which required careful navigation around such obstacles as trees, ditches and power lines and telephone lines. Eight hours later, the tank was three-quarters of the way to its destination. The hardworking team parked the entourage of vehicles at daybreak to comply with Florida Department of Transportation (FDOT) permit regulations.

At 9:00 p.m., the team resumed the journey to the job site, where the tank was delivered at 12:01 a.m. It was off-loaded on Monday morning, May 17, and set in place.

Moving costs for the sulfur melter tank totaled more than $50,000.00, but the bill represented a fraction of what it would have cost to move the tank in pieces and erect it on site. Constructing the tank in the field would have added some $119,857.00 to the contract amount. By shipping the completed tank, the contracting company, Devco USA, saved $63,357.00, in addition to alleviating safety risks and decreasing project completion time.
