About this file
This document is a technical engineering drawing for a Landing Platform-R1, a stainless steel marine structure designed for maritime applications. The assembly includes a fabricated 316L stainless steel base platform weighing 3,717 pounds total (2,662 pounds for stainless fabrication alone), measuring 168 inches in length, 69 inches in width, and 72-83 inches in height.
The platform incorporates molded fiberglass grating (McNICHOLS Products F261111C51) as the deck surface, with dimensions of 60" x 120" and cut-to-length sections. The structure features UHMWPE (ultra-high-molecular-weight polyethylene) fender pads per ASTM D6712 in black, including four central pads, one center horizontal pad, and two end horizontal pads. An aft face Duramax 4-inch fender with washer backing provides additional protection. The fabrication utilizes 316L stainless steel filler metal with 1/4-inch fillet welds throughout, with weld-affected zones to be scotch-brightened and polished. Hardware specifications include 130 units of 1/2" UNC x 3-1/2" stainless steel bolts with nuts and washers for UHMWPE fender assembly, and 14 units of 1/2" UNC stainless steel nuts and washers for Duramax hardware. The grating is fastened to the rim using McNICHOLS stainless steel clips (Type J2 and Type M2) spaced 12 inches on center around the perimeter. Detailed specifications for tolerance, materials, and construction methods are provided throughout the five-sheet drawing package.
