The Department of Defense, specifically the Portsmouth Naval Shipyard, is seeking to extend the rental of the DCCU System under Purchase Order N3904021P0201 on a Sole Source basis for an additional 18 weeks. This extension is necessary due to delays in the repair schedule of the USS Greenville caused by safety issues, which have resulted in a work stoppage and subsequent slowdown. The DCCU System is critical for maintaining strict environmental conditions required for shipyard operations, and any interruption in service could violate essential environmental and safety regulations.
