Art Anderson partnered with Granite Construction to provide critical engineering support for the large-scale repair and maintenance operations on the dam site at Deer Creek Dam and Reservoir on Provo River, Utah. This project had us performing multiple barge stability analyses, mooring assessments, turbidity curtain mooring, and various other engineering services to ensure safe operational loading and adequate mooring. Deer Creek is home to an earthen dam that’s undergoing significant component replacements. Built over 80 years ago, Deer Creek Dam and Reservoir delivers water to 1.5 million Utah residents.
The barge stability analysis scenario we developed was used to evaluate supporting dive and dredging operations. The stability analysis included the proper loading of equipment onto the barge.
Both our Naval Architecture team and Civil team worked closely together to tackle the project’s unique challenges, including the complex mooring scheme that involved both waterborne and shore-based anchors and all sorts of lifting analysis.
The scope of this project included a stability analysis of a crane barge with a 110-ton crane on board that sets the anchors and turbidity curtains, and included the installation and removal of a 192-inch bulkhead. We followed this work up with three barge stability analysis that contained 300 Ton crawler crane barge stability, excavator barge stability, and 200 Ton crane barge stability. For mooring and anchoring, two mooring analyses were performed – one at the dam and one at the sailboat beach. For each location, the worst condition mooring was considered. In addition, Art Anderson provided walk-on stability analysis, dive & material barge stability analysis, crane & excavator tie-down analysis, and ramp design when the barges are loaded at the sailboat beach location.
