Dredging and Underwater Operations

Naval Submarine Base (NSB) Kings Bay

8-koi removed sediment, undisturbed soils and other debris from the MSF and dry dock areas. The operation involved divers assisted by surface supplied air. 8-koi managed the dredging and diving operations from a 150’ barge with a 230-ton capacity crane and a tugboat. The teams used a 60-foot airlift maneuvered by the crane and a 2” Hand Water Jet operated by divers for critical areas near structures, to remove the materials from the dredge area. Underground sensors were calibrated, High voltage underwater cabling and other structures were protected. Required depth was in excess of 40 feet of mllw. 8-koi removed approximately 7,000 cubic yards of materials during the dredge operations.

Trident Wharf Utility Replacement

Cape Canaveral Space Force Station

This Design/Build Construction project required replacement of all mechanical piping, valves and appurtenances on the Trident Wharf. Value engineering consisted of changing the pipe material in the underground distribution to HDPE for corrosion resistance. Measures were taken for all the pier side utility replacement to ensure environmental permitting would not be required.

Systems replaced include:
-Force Main Sewer System
-Force Main Oily Waste System
-Segments of the DI Water distribution system
-Fire Water Distribution System including the replacement of existing and addition of redundant back flow preventers, new risers and -pier side hose reels.
-Low Pressure Air piping and replacement of the air drier
-Gravity sewer system from the support building

Communications Project

NAS JAX Hospital

This construction project involved the removal and replacement of the nurse call system, Public Address system, all synchronized clocks, and select phone circuits throughout the Naval Hospital at Naval Air Station Jacksonville. All work needed to be completed while the hospital was staffed and remained fully operational. Coordination was required with multiple departments and logistics were key for the successful acceptance of the new system prior to dismantling and removing the existing systems. Also, as part of this project several spaces were remodeled including new MPE services and finishes. Detailed record drawings, product data and video training programs were required as part of the project.
