877. A jack-up level at 12.5 feet draft transfers 100 kips of drill water from a tank with a TCG of -30 feet to a starboard tank with a TCG of 70 feet. The resulting starboard draft is 13 feet. The moment required to change list one inch (MCL1″) is __________.

The 100-kip weight shift creates a 10,000 foot-kip heeling moment, resulting in a 1-foot difference in drafts. Therefore, the moment required to change list one inch is calculated by dividing the total heeling moment by the change in list in inches, yielding 833 foot-kips.
