Location

Pearl Harbor Naval Shipyard & Intermediate Maintenance Facility (PHNSY & IMF), Honolulu, HI

Project Overview

NAVFAC Pacific awarded a $2.8-billion task order to the Dragados/Hawaiian Dredging/Orion JV for the five-year construction of Dry Dock 5 at Pearl Harbor. This critical infrastructure project will expand the Navy’s ability to maintain and modernize nuclear-powered submarines, ensuring the continued readiness of the U.S. Pacific Fleet.

As part of the Navy’s Shipyard Infrastructure Optimization Program (SIOP), this dry dock replacement supports the modernization of shipyard facilities, equipment, and layouts to handle the Navy’s nuclear-powered warships well into the future.

Objective

To safeguard sensitive construction activities during dredging and dry dock development, NAVFAC required a specialized turbidity curtain capable of reaching unprecedented depths. The curtain needed to contain suspended solids, prevent environmental impact, and maintain compliance with strict Navy and environmental standards.

GEI Works Solution

GEI Works manufactured and delivered a custom 50-foot deep specialty turbidity curtain, designed to perform in the demanding marine environment of Pearl Harbor.

Key Features:

• Depth: 50 feet – engineered for stability in deep-water operations
  
• Durability: Heavy-duty construction to withstand tidal changes, currents, and marine conditions
  
• Precision Fit: Tailored to safeguard dredging and construction zones within the Navy’s submarine facility
  
• Compliance: Met NAVFAC environmental protection requirements for sediment and turbidity control

Project Highlights

1. Mission-Critical Infrastructure Support
   The curtain played a key role in enabling dredging operations for the $2.8B Dry Dock 5 project, part of the Navy’s largest shipyard modernization initiative.
   
2. Custom Engineering Excellence
   GEI Works’ ability to deliver a 50-foot deep specialty curtain showcased innovation and adaptability for defense-related marine projects.
   
3. Environmental & Operational Safeguards
   The solution contained suspended solids effectively, allowing work to proceed while protecting Pearl Harbor’s waters.

Outcome

The custom GEI Works turbidity curtain successfully safeguarded construction operations at one of the Navy’s most strategic facilities. By preventing sediment dispersion, the curtain ensured compliance with environmental regulations while supporting uninterrupted progress on Dry Dock 5.

This project demonstrated GEI Works’ capacity to provide tailored, mission-critical solutions for some of the most demanding marine construction projects in the world.
