About this file
This document is a technical drawing for a ventilation modification plan for the R/V Kiyi, a research vessel operated by the US Geological Survey. The drawing details specific ventilation improvements, including the installation of a new 120 VAC axial fan with 115 CFM capacity and modifications to existing ventilation systems. The technical specifications include precise measurements, welding requirements, and material specifications, with notes specifying that all components must conform to ABS (American Bureau of Shipping) rules for marine vessel construction. The modifications involve changes to vents, sea chest areas, and piping, with detailed diagrams showing installation methods for the new ventilation components on the vessel's main deck and around ballast tank areas.
