🔍 Key Concepts

• Shoring principles for damaged bulkheads (support vs. force applied) • Difference between supporting existing loads and attempting to straighten/bend steel during damage control • Risks of changing the shape of a set (permanently deformed) bulkhead under water pressure

💭 Think About

• Ask yourself: when a bulkhead has a permanent set from pressure, is it usually safer to try to push it back into place, or to secure it in the position it has taken? • Consider what can happen to watertight integrity if you try to force a deformed bulkhead back toward its original position while pressure is still acting on it. • Which option best matches the idea of "controlling" the set so it does not worsen, rather than trying to reverse the damage?

✅ Before You Answer

• Verify which choices involve adding force to move/straighten the bulkhead versus simply supporting and holding it. • Double-check which option aligns with standard DC practice: shores are meant to support and prevent further movement, not to re‑shape structure under load. • Eliminate any option that significantly alters the stress pattern on a bulkhead already under water pressure, as this can cause sudden failure.
