Intact stability of double hull tankers

A SNAME Ad Hoc Panel on Tanker Stability was formed in response to concerns about the potential for lolling incidents dangerous to life, property, and the environment associated with certain double hull tankers. A working group was formed to investigate the influence of design parameters on the intact stability of double hull tankers. This report describes the results of that investigation. The value of tank arrangements utilizing centerline bulkheads in both cargo and ballast spaces was brought forth. The roles of breadth/depth ratio, specific gravity, lightship vertical center of gravity are documented. An addendum, titled ''Considerations for Lolling Prevention,'' was prepared by the full SNAME Ad Hoc Panel on Tanker Stability
