Ships without large openings on the upper deck, such as tankers, possess sufficient torsional strength, and no damage due to torsion has been reported. Bulk carriers and container ships have large openings on their upper decks, requiring hull structural designers to pay attention to torsional strength. In this chapter, two examples of actual damage due to torsion are explained, one for a container ship and the other for a bulk carrier.

摘要

Ships without large openings on the upper deck, such as tankers, possess sufficient torsional strength, and no damage due to torsion has been reported. Bulk carriers and container ships have large openings on their upper decks, requiring hull structural designers to pay attention to torsional strength. In this chapter, two examples of actual damage due to torsion are explained, one for a container ship and the other for a bulk carrier.
