Bureau Veritas says detailed warping analysis is the key to a crack-free new generation of containerships. "Some large containerships appear to be suffering cracking of longitudinals caused by fatigue and warping stress," says Pierre de Livois, technical director of Bureau Veritas Marine Division. "We are pleased that the many Panamax and post-Panamax containerships built with Bureau Veritas class show that extensive Finite Element Model analysis and attention to fatigue and structural details at the building stage have paid off. De Livois says, "We have been able to incorporate all our positive experience into different series of containerships built this year in various shipyards.
