🔍 Key Concepts

• Review the loading chart or table for the COASTAL DRILLER’s cantilever pipe rack at various extension lengths, especially at 40 feet aft of the transom. • Understand how uniformly distributed load (UDL) in kips/foot is applied over the available rack length when the cantilever is extended. • Pay attention to any notes or limits on maximum allowable load or governing capacity (e.g., pipe rack capacity vs. structural limit of the cantilever).

💭 Think About

• What is the allowable uniformly distributed load (kips per foot) for the pipe rack when the cantilever is extended 40 feet aft? • Over what effective length of the cantilever pipe rack is that load applied for this specific extension, according to the vessel’s loading data? • When you multiply the allowable kips/foot by the applicable length, how close do your results come to each answer choice?

✅ Before You Answer

• Verify you are using the correct UDL value that corresponds specifically to 40 ft aft extension, not another extension length. • Confirm the length used in your calculation matches the portion of the pipe rack that is allowed to carry the uniform load when extended 40 feet aft. • Check that your final total load is expressed in kips and that you haven’t mixed up kips/foot with total kips.
