Commercial Shipyards, Docks & Piers
Commercial shipyards are aging as well. Piers, docks, piles, tieback systems, and seawalls (bulkheads) are deteriorating and losing their ability to carry their intended loads. Infraspect has performed Deterioration Condition Assessments on commercial loading docks and tie-back systems that support thousands of tons of cargo a day.
Infraspect can provide vital information on the condition of a shipyard so that it may be repaired and await transport without interruption. The company loses money if it cannot load its vessels for shipment, but with Infraspect, there will always be peace of mind knowing the shipyard is in good condition.
Dock Pier & Tie Back Condition Assessments
Infraspect performed a dock, pier, and tie-back condition assessment of the commodores point terminal on the St Johns River in Jacksonville, Florida using our proprietary Non-Destructive Testing (NDT) methods. The terminal was constructed in 1938 and rebuilt in 1960. The terminal began experiencing breakthroughs of the deck with the outriggers of its 125-ton cranes.
Infraspect was called in to perform an in-depth deterioration assessment of 458,000 square feet of surface area and 768 tie-back rods. The owners were deciding whether to keep the terminal open or close it and turn it into waterfront townhomes.
The results of Infraspect’s inspection resulted in an overall fair to good condition with designated areas of repair. The tie-back system was intact and stable. The shipyard owners decided to repair the terminal and keep it open for service.
Dock Deterioration & Load Rating Analysis
Infraspect was contacted to perform a dock deterioration and load rating analysis of NASA’s MAF Barge dock in New Orleans, LA also utilizing our proprietary NDT methods. The facility was used to build fuel tanks for the space shuttle, load them onto a barge and transport them to Florida.
The dock was damaged during Katrina in 2005 and began showing signs of cracking in 2010.
Infraspect’s inspection results showed a stable substructure and normal aging of the dock surface. The deck cracking was due to pile failure under that section of the deck. The deck was repaired and is still in service today.
