Case Study
USNS SBX-1
EBDG led a complex weld engineering and inspection project for the USNS SBX-1 X-band radar vessel, part of the United States Department of Defense (DoD) Missile Defense Agency. Project success was attributed to a strong team of industry experts including our certified weld inspector (CWI) licensed engineers.
EBDG developed an optimized weld procedure for an uncommon grade of steel for Tote Services, LLC, in support of work on the SBX-1. The challenge on the project was to develop a regulatory-approved weld procedure appropriate to the steel used for the hull of the SBX-1. The steel is ABS grade FH-36 low temperature steel, suitable for service in arctic conditions, able to retain higher impact toughness in very cold ambient temperatures when compared to more common ABS grade A steel.
The existing weld procedure required expensive and specialty post-weld heat treatment. EBDG's weld procedure was carefully designed to avoid the need for heat treatment, saving weeks of schedule and expense during each shipyard period.
The regulatory agencies in control of the approval and oversight of the procedure included the American Bureau of Shipping (ABS) and United States Coast Guard (USCG), in support of the DoD Military Sealift Command (MSC).
