Written by GovTribe AI · Sep 3, 2026

This is a technical engineering drawing prepared by TGMD, Inc. for a Great Lakes Research Vessel, specifically depicting the anchor handling arrangement. The document serves as a detailed design plan that illustrates the vessel's structural configuration and mechanical systems related to anchor deployment and management.

The drawing presents multiple plan views and sectional details across six columnar sections, including an upper deck plan view, main deck plan view, elevation view, bulkhead detail, and various cross-sectional details labeled 1-D through 6-B. The document contains anchor calculations and specifications in the upper left quadrant, outlining the mathematical basis for the anchor system's design load capacity and structural requirements. Key components depicted include the anchor winch system, existing bull units, control mechanisms, and the vessel's frame structure. The drawing references specific marine engineering standards and includes a revision table noting document control information. Technical specifications appear throughout, with measurements and material callouts embedded in the various detail views. The references section identifies this as part of a broader marine vessel design project, with plan numbers and marine design center documentation noted in the lower right corner.
