Objective:
The project objective is to determine the feasibility and cost savings of reducing or eliminating temporary bracing, additional back up structure, and deck and bulkhead inserts with the use of equalizing loader bars for lifting and turning thin plate blocks and grand blocks as compared to traditional lifting arrangements.
Summary:
The project team will focus on the following methods and procedures to accomplish goals and objectives:
- Develop traditional lifting arrangements for a set of thin plate blocks and grand blocks
- Develop lifting arrangements using “equalizing loader” type lifting bars for the same set of thin plate blocks and grand blocks by applying best practices
- Assess the potential for reducing or eliminating temporary bracing, additional back up structure, and deck and bulkhead inserts based on a comparison of the lifting arrangements
- Perform a gap analysis in overall work content using both lifting arrangements
- Identify potential cost reductions
The results of the research accomplished will enhance the collective understanding of using an equalizing load bar. Savings gained from industry-wide availability of the study will collectively reduce the cost of building ships.
