Placing and Compacting 400,000 Cubic-Yards of Fill in the Thames River for the Redevelopment of the Connecticut State Pier Complex, New London, Connecticut
The State Pier complex in New London, Connecticut was redeveloped as a purpose-built facility for marshalling heavy cargo, specifically offshore wind turbine components. The facility prior to redevelopment consisted of two adjacent piers with a deepwater berth between them, referred to as “Central Wharf”. The redesign intended to connect the two piers by filling Central Wharf and creating a solid-filled staging area. The infill of Central Wharf needed to be placed and compacted through 35 feet of water over a thin layer of soft organic silt present at the former mudline. The soft organic soils had to remain in place and could not be mobilized (mud wave) as the fill was placed. The project team developed an innovative, low-cost method to immobilize the organic silt prior to mass filling. The team then developed deep compaction strategies to meet the project specifications. The unique observational approach utilized provided a simple and low-cost solution to challenging site conditions.
Nearshore /Offshore Pile Driving and High Strain Dynamic Testing: Prediction, Installation, and Results
Glenn Santulli, P.E.
GRL Engineers
Glenn will be presenting on dynamic testing and wave equation analysis for offshore and near shore projects on the east coast of the US and Caribbean Sea. Drivability analyses and bearing graph analyses were performed via wave equation analysis along with high strain dynamic testing performed on Jacket piles in the Delaware River for new lighting tower foundations for the US Coast Guard. Dynamic testing results were utilized immediately after testing to allow for construction of pile jackets to be constructed in a timely fashion and cost-effective manner in the Delaware River. Drivebility analyses were performed to estimate if pile order lengths would need to be adjusted prior to barging piles to the site location. Other topics to be discussed will be jacket piles in the Caribbean sea that had dynamic testing performed that showed soil set-up would be necessary after a wait period in order for the offshore loads to be achieved by use of developed setup factors. Additional topics include offshore wind mono-pile dynamic monitoring and the future of testing in the offshore wind industry.
