This document is a technical drawing specification for remote operating gear modifications on the NOAA Ship Gordon Gunter, a ballast water research vessel. The drawing set comprises detailed engineering plans and sections showing structural modifications, piping installations, equipment mounting, and component specifications for retrofitting remote operating systems throughout the vessel.

The specifications include comprehensive bill of materials detailing pipe fittings, valves, tanks, couplings, and associated hardware with material requirements (primarily steel and stainless steel per ASTM standards), precise dimensional specifications across multiple deck plans and sections, and installation requirements for systems including fuel oil piping, freshwater systems, ballast tank modifications, and auxiliary equipment. General notes establish construction standards requiring adequate supports for remote operating gear assemblies, painted finishes matching surrounding areas, photographic documentation of label plates on aluminum per specifications, and universal joint restrictions for shaft connections. Test procedures mandate hydrostatically testing new cross-flooding piping at 100 PSI with a 10-minute hold period, post-test pressure testing and tightness verification of ballast cross-flooding installations, tank vents tested in conjunction with tank service, and sounding tube testing for proper operation and unobstructed flow. The drawings reference multiple plan views, elevations, details, and sections across the vessel including main deck, hold configurations, and various tank installations to ensure complete integration of the remote operating gear modification system throughout the vessel structure.
