101-6634906 Structural standards.pdf

This is a structural standards drawing for TAGS 51/52 coastal hydrographic survey ships for the Department of the Navy Naval Sea Systems Command. The document serves as a technical specification and design reference for deck covering schedules and associated structural details.

The drawing package contains 47+ detailed sheets establishing structural standards for ship construction, including specifications for welding details, bracket configurations, connection types, and component positioning. Key structural elements detailed include bulkhead (BHD) stiffeners, deck connections, chine bars, pipe stanchions, and various bracket types at specific locations throughout the vessel. The drawing incorporates multiple revisions (designated A through J) with modifications tracked through change zones, addressing items such as welding schedules, note revisions, detail designations, and dimensional adjustments. Specific details covered include watertight/oiltight (WTRTT/OT) bulkhead end connections in 12", 15", and 18" variants, deck-to-bulkhead connections, typical deck connections, and stair cutout configurations. All welding is specified to comply with ABS (American Bureau of Shipping) rules for building and classing steel vessels. The document references contract number N00024-89-C-2079 and establishes construction standards for the referenced class of coastal survey vessels through detailed engineering drawings and technical specifications.
