A MODU with the TCG off the longitudinal centerline inclines to an angle of _______________.

A loll
B heel
C trim
D list
AI Explanation

The correct answer is D) list. When a MODU (Mobile Offshore Drilling Unit) has the TCG (Transverse Center of Gravity) off the longitudinal centerline, it will incline or "list" to one side. List refers to the inclination of a vessel from the upright position in the transverse (side-to-side) direction, caused by an off-center distribution of weight. This is different from heel, which is the inclination in the longitudinal (front-to-back) direction, or trim, which is the difference in draft between the forward and aft ends of the vessel. The other options, loll, heel, and trim, do not accurately describe the inclination caused by an off-center TCG on a MODU, which is correctly referred to as a list.
