The efforts in this project are focused specifically on analyzing the pertinent noise transmission and radiation mechanisms associated with driving large monopile foundations. Further, the project will identify specific mitigation concepts appropriate to those mechanisms and assess the potential performance of those approaches with the context of achievable engineering design.
Phase 1 of the study is complete and the final report for Phase 1 is posted below. A second phase is exploring the engineering feasibility of a dewatered cofferdam. APS, along with the subcontractor RPS Group of Houston, has developed the initial design drawings. The draft final report on this phase is under preparation.
