About this file
This document is a technical drawing detailing davit modifications for the R/V KIYI, a research vessel owned by the US Geological Survey located in Ashland, WI. The drawing, created by JMS Naval Architects, shows a detailed schematic for modifying existing pipe sections and equipment on the vessel's deck, specifically focusing on a 36" long, 6" Schedule 40 pipe section. The technical specifications include requirements for welding in accordance with ABS Rules for Building and Classing Marine Vessels, with all steel materials to conform to ABS requirements and be ABS Grade A.
The drawing includes precise measurements for the vessel (106'-7" x 27' x 11-10 3/4"), and indicates modifications to existing equipment such as grease fittings, plate flanges, and deck brackets. The technical drawing is dated 05/21/2025 and is part of the documentation for MDC Hull 589, providing a detailed engineering view of the proposed davit modifications with scaled views of the focsle deck and main deck configurations.
