About this file
This document is a drydock evaluation form for the USS EMORY S LAND (AS-39) undergoing a regular overhaul and drydocking. The form provides ship characteristics including length, breadth, draft, and displacement to determine drydock suitability. Minimum clearances for positioning the ship in drydock and maximum loading pressures on blocks are also specified. The form outlines minimum services required from drydocks including electrical power, sewage connections, fire main, seawater, fresh water, compressed air, and steam. Safety response plans for firefighting, flooding, earthquakes, and typhoons are required. Shipyards must certify their drydock meets the ship's particulars and required services.
The related federal contract opportunity is solicitation N3220520R6501 issued by the Department of the Navy Military Sealift Command for the USS EMORY S LAND regular overhaul and drydocking.
