Attachment 09 - IX528 General Specifications.docx

Attachment 09 is a technical specification document detailing the physical characteristics of the IX528 Service Craft, a naval vessel used at the Southeast Alaska Acoustic Measurement Facility (SEAFAC). The vessel specifications include precise measurements such as a 150'-0" molded length, 46'-0" beam, 6'-6" draft, 1035 long tons displacement, and constructed of welded steel with 24-inch frame spacing. The craft features a significant sail area of 5,345 square feet, stands 85'-6" tall including the mast, and was originally keel-laid in 1943.

This specification document is part of a larger Naval Sea Systems Command solicitation (N0016725R1001) for Barge Preservation, Inspection, Repair, and Maintenance (PIRM) Support Services. The solicitation involves maintaining two service craft (IX527 and IX528) permanently moored at the SEAFAC static site in Western Behm Canal near Back Island, Alaska. These modified vessels are critical to acoustic research and development for Pacific Fleet submarines, with specialized features including a moon pool and large deckhouse structure.
