On the COASTAL DRILLER, the maximum aft extension of the cantilever places the rotary __________.

🔍 Key Concepts

• Cantilever maximum aft extension as shown on the COASTAL DRILLER rig plan/arrangement drawing • How the rotary table centerline is located relative to a reference point like the transom • Using distances and offsets from the rig’s cantilever load chart or general arrangement (GA) plan

💭 Think About

• Look at where the cantilever is when it is fully extended aft: how far does the rotary center move from its neutral/zero position? • Identify what point on the drawing is called the transom and then trace the dimension line that shows the rotary location at maximum aft extension. • Compare the listed answer choices to the dimension(s) on the drawing – which one directly matches the labeled rotary-to-transom distance at max aft?

✅ Before You Answer

• Confirm you are reading the maximum aft extension position, not the neutral or forward position on the cantilever diagram. • Verify that the measurement is from the rotary centerline to the transom, not to another reference such as the jackhouse or bow. • Double-check the units and scale on the drawing so the feet value you read aligns with one and only one of the four answer choices.
