September 2014 - July 2018

Objective:
The objective of this project was to perform basic research related to lifting attachment devices used for ship construction, expanding on the volume of work already completed during previous projects and work in progress at San Diego State University (SDSU). The emphasis was to perform full-scale or near-full-scale structural tests of lifting components with several application methods similar to those used during ship production. Of particular interest was to capture the effects of different loading scenarios, for various padeye shapes and alignment configurations.
Summary:
The project was divided into three, one-year phases. Each phase focused on a select few areas of shipyard rigging. The first phase focused on loading and transmission of padeyes and bulkheads. The second phase focused on the alignment and configuration of padeyes and supporting structure. The final phase looked into padeyes of different materials, and the effects of temporary stiffening structure used during block rotations.
The Final Report is available to the U.S. shipbuilding and ship repair industry.
