Guam Underwater
Construction
Precon Marine has completed multiple underwater construction projects in Guam involving dredging and excavation, underwater cable installation, marine equipment installation, and specialized diving operations. One documented project involved the installation of an Underwater Electro-Magnetic Measurement System at Polaris Point. The project included approximately 1,200 cubic yards of dredging, MEC/UXO screening, underwater sensor installation, and more than 100,000 linear feet of cable lay connecting the underwater system to shore-based equipment.
This work required careful coordination of underwater construction, excavation, commercial diving, cable installation, and shore-side infrastructure. Precon Marine’s experience with these specialized operations allows the company to approach Guam marine projects where construction and installation activities must be performed safely and accurately below the waterline.
