Statement of Work 26Q8039.pdf

This is a Performance Work Statement (PWS) specification for floating mast wire rope maintenance pendants for a Portal Crane.

The contractor must provide two maintenance pendants to support a Portal Crane's floating mast in the vertical position. The wire rope shall be 6×19 (or 6×36) class, improved plow steel (IPS/Grade 1570) or greater, pre-formed with a bright non-galvanized finish and Right Regular Lay (RRL) construction. The rope must have a fiber core, independent wire rope core (IWRC), wire strand core, or steel core, with a nominal diameter of 2-1/4" (±5%/-0%), a length of 45 feet (±1/2"), and a minimum breaking strength of 400,000 pounds. The rope must conform to Federal Specification RR-W-410J and feature two open spelter socket end connections using unpainted cast steel alloy Crosby S-416 open spelter sockets (Crosby part number 1039888). End connections shall be either poured spelter or resin-fabricated per Naval Ships' Technical Manual (NSTM) S9086-UU-STM-010 Chapter 613 Rev. 5 specifications.

Inspection requirements include pre-delivery socket examination and full wire rope inspection by government Code 700 personnel at Portsmouth Naval Shipyard at destination. End connections must be inspected for excessive wear, broken wires, stretching, kinking, twisting, or undue looseness. Pre-delivery testing requires actual breaking strength determination per ASTM A931-18 exceeding 73,464 pounds, with the socket end connection pull-tested to the same load. The contractor must submit ASME B30.30-2023 certifications with positive traceability, documentation of socket end connection pull-test results, and Charpy V-notch test reports for each open spelter socket. Final government acceptance occurs at Portsmouth Naval Shipyard receiving activity only after all inspection criteria are met, deficiencies are corrected, and government approval is obtained for all data items.
