Question 1 of 27070

Which of the following describes the purpose of a striker or doubler plate?

🔍 Key Concepts

• Striker / doubler plates on tank tops or bulkheads • Where a sounding tape and bob actually makes contact with the structure • Difference between supporting machinery vs. protecting structure from repeated impact

💭 Think About

• On a real ship, where would you physically see a striker or doubler plate installed? Picture yourself taking soundings in a tank. • Ask yourself: is the main job of a striker/doubler plate to carry continuous load, to stop over‑travel, or to take repeated small impacts in one location? • Which option talks about a function that happens right at the steel surface where a weight or tool keeps hitting the same spot over and over?

✅ Before You Answer

• Verify which choice relates directly to tanks and soundings. • Check which answer best fits the idea of local reinforcement of plating rather than a general foundation for heavy machinery. • Eliminate any option that describes a device inside the valve or machinery, instead of extra steel plate welded to the structure.
