About this file

Written by GovTribe AI · Jun 23, 2025

This document is a detailed engineering drawing set for keel cooler modifications for the R/V Kiyi research vessel, prepared by JMS Naval Architects for the US Geological Survey. The technical drawings provide comprehensive schematics for modifying existing keel coolers, including multiple detailed views and cross-sections showing piping configurations, mounting details, bolt patterns, and dimensional specifications. The drawings are marked "PRELIMINARY" and cover modifications to the vessel's cooling system, with specific attention to recess guards, pipe connections, and structural adjustments to the existing keel cooler infrastructure.

The technical specifications include precise measurements for various components, a bill of materials listing pipe sizes and quantities, and general notes emphasizing dimensional accuracy and welding requirements. The drawings are part of project MDC HULL 589 for the vessel located in Ashland, WI, and are dated January 2020. The technical drawings provide engineering-level detail for fabrication and installation of the keel cooler modifications, with scaled views and intricate mechanical design elements that would guide manufacturing and installation processes.
