Without proper management, the shifting liquid in a ship’s tanks can create a lethal scenario. Free surface moment (FSM) is one of the most frequently misunderstood elements in ship operation. The deck officer that values their life wants to understand free surface moment. The physics behind it, and how it applies to ship operating limits.

What science could possibly link moving a few weights on deck with calculating the light ship weight? Armed with knowledge, we carefully exploit physics to achieve high quality science without the fancy equipment. Today I explain some of the theory behind the stability test.

PANIC! That should be your reaction if your ship developed a permanent list. Angle of loll shines like a bright red warning sign, indicating serious stability problems. Today we discuss an angle of loll (AOL): what it is, how to find it, and what to do about it.
