The DEEP DRILLER, loaded as shown in Sample Load Form #2 (Ballast to Survival), suffers major damage which results in flooding in tank 10S. Your best countermeasure is to __________.
ā¢ Effect of flooding on stability (heel, trim, GM) when a side tank like 10S is damaged ā¢ How counterflooding can correct a list vs. how pumping from sound tanks can worsen it ā¢ Reading the Sample Load Form #2 (Ballast to Survival) to see which tanks are paired and how they affect transverse balance
ā¢ When a single side tank (10S) floods, which way will the rig tend to heel, and why? ā¢ If you remove ballast from another starboard tank versus a port tank, what happens to the list? Think about moments around the centerline. ā¢ Look at the load form: which tank is the proper āopposite partnerā to 10S in terms of transverse location and effect on stability?
ā¢ Identify whether 10S is port or starboard and how its flooding shifts the center of gravity (G) and center of buoyancy (B). ā¢ Determine which listed tank(s) are on the same side as the damage and which are on the opposite side. ā¢ Verify from the Sample Load Form which option best restores transverse balance without creating an excessive loss of overall stability.
