About this file
This document is a detailed technical drawing for shaft seal modifications on the R/V KIYI, a research vessel operated by the US Geological Survey in Ashland, WI. The drawing specifies the installation of a new 5" Drymax shaft seal and adapter plate for MDC Hull 589, which involves modifying the existing propulsion system components. Key technical specifications include replacing the existing shaft seal and adapter plate while rerouting the 1" SCH 80 water supply to the new seal housing, with all work to be performed in accordance with ABS (American Bureau of Shipping) rules for marine vessel construction.
The drawing provides precise installation instructions, including requirements that all dimensions be confirmed prior to installation, welding must conform to ABS rules, and all materials and components must meet ABS requirements. The modifications involve working with an existing Cummins QSK-19 engine (660HP @ 1800RPM) and existing engine girder, with the shipyard responsible for supplying any additional hardware not provided by the equipment manufacturer. The technical drawing is prepared by JMS Naval Architects, located in Mystic, CT, and is dated 05/21/2025.
