1547-2510 Rev 7 Long l Struct Sections 3.pdf

This is an engineering drawing showing longitudinal structural sections and modifications for a vessel, with detailed technical specifications related to the Training Vessel Freedom Star dry dock repairs. The drawing illustrates several key modifications including typical lightening holes created when converting a void to a centerline flume tank, new sewage tanks outboard port and starboard, and various structural details like bulkhead sections, doors, and face plates.

The drawing contains multiple longitudinal sections at different offset positions from the centerline, with specific dimensions and technical specifications for materials such as face plates (FB4x3/8"), collar details, and manhole specifications. Notable features include details of a bulkhead at 21" off centerline, engineering girders, and tank modifications between frames 41-35 port and starboard. The revision notes indicate these changes were made in July 2013 and include the addition of "as-found" lightening holes and modifications to existing structures.
