🔍 Key Concepts

• Effect of removing weight (discharging liquids) on vessel draft and displacement • How to use the TPC (tons per centimeter immersion) or MT1" (Moment to Trim 1 inch) data on the load form or hydrostatic table • Relationship between weight removed, change in displacement, and change in mean draft

💭 Think About

• First, think about what happens to the vessel’s displacement and draft when you pump out water from tanks 6 and 25. Does the draft increase or decrease? • Use the sample load form: identify how many tons of drill water you are removing and subtract this from the original displacement. Then determine the new mean draft from the displacement–draft data. • Consider whether removing water from tanks 6 and 25 will mainly change the overall mean draft, or if trim (bow vs. stern) could significantly affect the draft readings used in the question.

✅ Before You Answer

• From Sample Load Form 1, find the original displacement and corresponding original mean draft. • Accurately calculate the total weight of drill water removed from tanks 6 and 25 (check tank capacities, specific gravity, and percent full). • Use the hydrostatic/displacement–draft table on the form to match the new, reduced displacement to the closest mean draft before picking a choice.
