Disadvantages of Double Hull Design

• Depending on their location, geometric configuration and construction, a combination of service loads, residual stresses and corrosion can result in coating breakdown and fatigue cracks.
• This can lead to ongoing propagation and eventual structural failure.
• Use of higher tensile steel has also contributed to fatigue failures.
• Undetected corrosion has been a major cause of some of the most noteworthy marine disasters.
• A paper produced by OCIMF highlights the difficulties of coating, inspecting and maintaining the ballast spaces, with a complex arrangement of internal stiffeners, brackets and associated structural details.
