WP-07G AHU-9 Addition V1.pdf

Abstract The intent of this work package is to describe the modification of HVAC currently serving the forward staterooms on the 01 Level (spaces between frames 16-36). The forward staterooms are currently served by AHU-2 which is located in 01-60-2. A new AHU (air handler unit) will be installed in the space that is currently Deck Locker 01-16-4. Deck Locker 01-16-4 will be divided into two spaces. HVAC ducting will be modified such that the newly installed AHU will serve the spaces between Frames 16 and 36 on the 01 Level as well as Scientific Stores (1-8-0). Following these modifications, AHU-2 will serve the Mess, Conference Room, Lounge, and Galley.

These modifications were implemented on two sister ships (Roger Revelle and Atlantis) and resulting as-built drawings were developed. The as-built for the Roger Revelle is shown in Reference 4. This work package will implement the same modifications on the Ronald H. Brown.
