About this file
This technical drawing depicts a 3 Meter VE Discus Buoy Flotation Element for the National Data Buoy Center (NDBC) at Stennis Space Center. The detailed engineering schematic shows a yellow circular flotation component with precise dimensional specifications. The hull is constructed from ionomer foam using Surlyn or Iotek resin, specifically requiring closed-cell foam with individual non-connecting cells. Key technical specifications include a 120.00 OD diameter, 6x 0.63 inch through holes on a 43.00 BC, and a color specification of yellow (Federal Standard 595 color #13655). The drawing includes top view, section A-A view, and an isometric view, with tolerances of +/- 0.05 inches for decimals and +/- 0.5 degrees for angular measurements. The document is part of contract EA133W-12-CN0050 and was approved by multiple NDBC engineering personnel in early 2018.
