New London State Pier in 2023

Haley & Aldrich geotechnical team supports first U.S. pier tailored to offshore wind industry 

Eight times

the typical shipping pier loading requirements

First of its kind

port on the East Coast of the United States

1 million homes

estimated to be powered by related wind projects


  • The port of New London, Connecticut, is ideally located to support offshore wind installations. But its two existing piers — both of which were built more than 100 years ago — needed significant upgrading to support the heavy weight of offshore wind turbine components.  
  • The new single pier would have to bear more than eight times as much weight as a typical shipping pier. Poor subsurface conditions and historical structures complicated the design and construction. 
  • To meet the project’s challenges, we drew on our extensive port experience to efficiently conduct land and underwater subsurface investigations. We also provided geotechnical engineering recommendations to guide the construction of the new pier and improvements to the site, and we monitored construction, including the installation of piles, the placement of infill placement, and the vibrocompaction of underwater soils. 
  • Our work made it possible for New London to position itself as a hub for offshore wind development and provided the infrastructure to deliver on the first three wind projects planned for the region.
