Wharf Repairs at Naval Submarine Base Kings Bay

PROJECT DETAILS

This project involved extensive repairs and improvements to the Explosive Handling Wharf (EHW1) at SUBASE Kings Bay. Key components of the scope included approximately 5,420 cubic yards of reinforced concrete repairs on piles, pile caps, bull rails, beams, under-deck areas, and capstan foundations. A metalizing and cathodic protection system was installed on reinforced concrete pile caps, covering approximately 1,887 square feet of wharf concrete pile cap and 140 square feet of concrete piles. Anodes were installed and repairs were made to the bonding harness system on approximately 667 steel piles.

Additionally, the fender wraps on 207 steel piles (30″ and 24″) were cleaned, coated, and replaced using Denso wraps. The driver’s float was replaced, and repairs were made to guide piles, along with miscellaneous repairs to mooring hardware, fender piles, and utility structures. Divers were utilized for pressure washing, chipping, and cleaning loose concrete, and they installed Cathodic Protection Jackets for approximately 667 concrete piles. Various electrical repairs were conducted, including the replacement of power cable brackets, and additional incidental work was performed as required. Throughout the project, strict adherence to maritime safety requirements was maintained.

Specialized Marine Construction at Kings Bay

Precon Marine’s work at Naval Submarine Base Kings Bay required a combination of concrete repair, cathodic protection, commercial diving and specialized marine construction capabilities. Work was performed on critical wharf infrastructure both above and below the waterline while maintaining strict maritime safety requirements.
