| Abstract | After numerical and physical modeling, and alternate analysis, the proposed solution to mitigate wave energies entering Kahului Harbor, Maui was to construct a submerged concrete caisson breakwater, just outside the harbor that would economically improve the harbor tranquility and be environmentally friendly. One of the major challenges of this project is that construction is to be completed over a five-month period, during the summer months, when there are no swells. This requires as much prefabrication as possible, detailed planning, and precise scheduling. Construction of the individual caisson units is proposed to take place in a dry dock, cast in a single pour to avoid cold joints. On completion, it will be floated and tugged away from the dry dock and placed onto a heavy lift vessel and transported to its installation site at Kahului. Various alternate methods of transportation were studied and discarded. Also proposed is the transplantation and seeding of coral fragments on the caisson units to enhance the durability and increase the longevity of the submerged breakwater. This submerged breakwater caisson project will be the first of its kind for mitigating wave energies entering a harbor. This paper aims to present a viable construction methodology. |
