You are planning the stowage of two incompatible products on your multiple-product tankship. What will NOT provide the minimum required segregation?

Correct Answer: Option D — Solid (non-intercostal) bulkhead

Under 46 CFR Part 153, a solid non-intercostal bulkhead provides physical continuity and absolute containment between adjacent tanks, thereby preventing cargo intermixture and failing to provide the specific minimum required segregation distance for incompatible reactive chemicals.
